Supporting collaborative dissection through the development of an online wiki positively impacts the learning of veterinary anatomy.

An innovative series of dissections of the canine abdomen was created to facilitate social distancing in the dissection room following COVID-19 restrictions imposed in the UK. In groups of six, first-year veterinary students took turns dissecting selected parts of the canine abdomen while maintaining social distancing and documenting their work with video and photographs. Here, students learned about the canine abdominal anatomy by dissecting, recording the dissections of others in their group, and compiling the recorded material into a collaborative electronic media portfolio (Wiki). An online formative multiple-choice test was created to test students' knowledge of the canine abdominal anatomy. The result analysis showed that although students achieved the learning outcomes only by studying the Wiki, they had better performance in the anatomical areas where they learned through the dissection (p < 0.05). Student performance was very similar in the areas in which they were present in the dissection room and participated in recording the dissection compared with the areas that they effectively dissected (p > 0.05). A qualitative thematic analysis was developed to understand students' opinions via their feedback on this dissection approach. Our results showed that student collaboration and the development of practical skills were the most valued aspects of this dissection teaching initiative. Moreover, these results show that developing a group Wiki has a positive impact on student achievement of learning objectives, with a practical hands-on dissection being fundamental for the optimal learning of the canine abdominal anatomy.

Establishing a veterinary anatomy core syllabus through a modified Delphi process.

Anatomy forms a key component of veterinary curricula, but, in the context of an evolving profession, curricula are adapting and changing accordingly. There is a lack of guidance for educators regarding the levels of anatomical knowledge required for a graduate to be considered safe or competent. A formal review of veterinary anatomy learning outcomes (LOs) is therefore timely to support curriculum development in this rapidly evolving field. This study aimed to create a set of LOs which reflect the recommended core requirements for a new graduate veterinarian. A consensus approach using a modified Delphi method was used. The Delphi panel consisted of 23 experienced and active veterinary anatomy educators from veterinary schools within the UK and Ireland. The process had four stages: (1) Research team review, pre-screening and modification of a list of existing LOs (adapted from the Core Regional Anatomy Syllabus) which then formed the initial set of outcomes sent for review; (2) Delphi Round 1; (3) Delphi Round 2; (4) Post-Delphi final screening and review. Qualitative data outlining the rationale for modification and rejection of LOs were analysed via content analysis. 167 LOs were initially presented to the Delphi panel in Round 1. 64 of those were accepted, 79 recommended for modification and 23 rejected. 122 LOs were presented to the Delphi panel in Round 2. Of these, 86 outcomes were accepted, 10 modified and 26 rejected. 160 LOs were ultimately accepted and form the Veterinary Anatomy Core Syllabus. Key themes arising from analysis include the removal of unnecessary detail and increased focus on the relevance of competencies required of a new veterinary graduate. The syllabus presented may be used by curriculum planners, teachers and students within veterinary education worldwide.

Anatomy in Practice: How Do Equine and Production Animal Veterinarians Apply Anatomy in Primary Care Settings?

To successfully prepare veterinary undergraduates for the workplace, it is critical that anatomy educators consider the context in which developing knowledge and skills will be applied. This study aimed to establish how farm animal and equine general practitioners use anatomy and related skills within their daily work. Qualitative ethnographic data in the form of observations and semi-structured interviews were collected from 12 veterinarians working in equine or farm animal first-opinion practice. Data underwent thematic analysis using a grounded theory approach. The five themes identified were relevant to both equine and farm animal veterinarians and represented the breadth and complexity of anatomy, its importance for professional and practical competence, as well as the requirement for continuous learning. The centrality and broad and multifaceted nature of anatomy was found to challenge equine and farm animal veterinarians, highlighting that essential anatomy knowledge and related skills are vital for their professional and practical competence. This aligns with the previously described experiences of companion animal clinicians. In equine practice, the complexity of anatomical knowledge required was particularly high, especially in relation to diagnostic imaging and assessing normal variation. This resulted in greater importance being placed on formal and informal professional development opportunities. For farm animal clinicians, anatomy application in the context of necropsy and euthanasia was particularly noted. Our findings allow anatomy educators to design appropriate and effective learning opportunities to ensure that veterinary graduates are equipped with the skills, knowledge, and resources required to succeed in first-opinion veterinary practice.

Effect of gamified perceptual learning on visual detection and discrimination skills in equine gait assessment.

BACKGROUND: Visual assessment of equine lameness is an everyday veterinary task suffering from poor diagnostic accuracy. The aim of this study was to quantify the impact of the perceptual learning game 'LamenessTrainer' on skill development. METHODS: Thirty-six undergraduate veterinary students engaged in four game modules teaching the assessment of fore- and hindlimb lameness. Computer animations of horses in this game displayed 0% (sound) to 70% (moderately lame) vertical movement asymmetry of head and pelvis. Performance, learning effects, diagnostic accuracy, detection thresholds and survey responses were analysed. RESULTS: Following staircase learning, more than 80% of students reliably classified horses with ≥20% asymmetry for forelimb lameness, ≥40% asymmetry for simplified hindlimb lameness and ≥50% asymmetry for realistic hindlimb lameness. During random presentation, on average 82% of sound and 65% of lame horses were assessed correctly during forelimb lameness evaluation, dropping to 39% of sound and 56% of lame horses for hindlimb lameness. CONCLUSION: In less than two hours, systematic perceptual learning through deliberate practice can develop visual assessment skills to an accuracy level comparable to expert assessors scoring the same animations. Skills should be developed further to improve misclassifications of sound and mildly lame horses, especially for hindlimb lameness evaluation.

Ontogenetic scaling of pelvic limb muscles, tendons and locomotor economy in the ostrich (Struthio camelus).

In rapidly growing animals there are numerous selective pressures and developmental constraints underpinning the ontogenetic development of muscle-tendon morphology and mechanical properties. Muscle force generating capacity, tendon stiffness, elastic energy storage capacity and efficiency were calculated from muscle and tendon morphological parameters and in vitro tendon mechanical properties obtained from a growth series of ostrich cadavers. Ontogenetic scaling relationships were established using reduced major axis regression analysis. Ostrich pelvic limb muscle mass and cross-sectional area broadly scaled with positive allometry, indicating maintained or relatively greater capacity for maximum isometric force generation in larger animals. The length of distal limb tendons was found to scale with positive allometry in several tendons associated with antigravity support and elastic energy storage during locomotion. Distal limb tendon stiffness scaled with negative allometry with respect to body mass, with tendons being relatively more compliant in larger birds. Tendon material properties also appeared to be size-dependent, suggesting that the relative increased compliance of tendons in larger ostriches is due in part to compensatory distortions in tendon material properties during maturation and development, not simply from ontogenetic changes in tendon geometry. Our results suggest that the previously reported increase in locomotor economy through ontogeny in the ostrich is due to greater potential for elastic energy storage with increasing body size. In fact, the rate of this increase may be somewhat greater than the conservative predictions of previous studies, thus illustrating the biological importance of elastic tendon structures in adult ostriches.

Anatomy Teaching, a "Model" Answer? Evaluating "Geoff", a Painted Anatomical Horse, as a Tool for Enhancing Topographical Anatomy Learning.

Development of new methods for anatomy teaching is increasingly important as we look to modernize and supplement traditional teaching methods. In this study, a life-sized equine model, "Geoff," was painted with surface and deep anatomical structures with the aim of improving students' ability to convert theoretical knowledge into improved topographical anatomy knowledge on the live horse. Third and fourth year veterinary medicine students (n = 45) were randomly allocated into experimental (used "Geoff") and control (used textbook) groups. The efficacy of the model was evaluated through a structured oral exam using a live horse. Questionnaires gathered information on student confidence and enjoyment of the task. There was no significant difference in the performance of experimental and control groups either immediately (44±20% vs. 40±21%; P = 0.504) or 9 weeks after the learning intervention (55±17% vs. 55±20%; P = 0.980). There were however specific questions on which the experimental group performed better than controls, and for which gender effects were apparent. The students using "Geoff" showed a transient gain in confidence following the session (Likert scale 2.7 to 3.6) however the initial increase was no longer present at the second test. There was a significant influence of gender on confidence with greater confidence gains in females in the Experimental group. The students found the model to be extremely useful and both groups found the sessions enjoyable. The model will be of benefit as a complementary learning tool for students.

Comparative functional anatomy of the epaxial musculature of dogs (Canis familiaris) bred for sprinting vs. fighting.

The axial musculoskeletal system of quadrupedal mammals is not currently well understood despite its functional importance in terms of facilitating postural stability and locomotion. Here we examined the detailed architecture of the muscles of the vertebral column of two breeds of dog, the Staffordshire bull terrier (SBT) and the racing greyhound, which have been selectively bred for physical combat and high speed sprint performance, respectively. Dissections of the epaxial musculature of nine racing greyhounds and six SBTs were carried out; muscle mass, length, and fascicle lengths were measured and used to calculate muscle physiological cross-sectional area (PCSA), and to estimate maximum muscle potential for force, work and power production. The longissimus dorsi muscle was found to have a high propensity for force production in both breeds of dog; however, when considered in combination with the iliocostalis lumborum muscle it showed enhanced potential for production of power and facilitating spinal extension during galloping gaits. This was particularly the case in the greyhound, where the m. longissimus dorsi and the m. iliocostalis lumborum were estimated to have the potential to augment hindlimb muscle power by ca. 12%. Breed differences were found within various other muscles of the axial musculoskeletal system, particularly in the cranial cervical muscles and also the deep muscles of the thorax which insert on the ribs. These may also highlight key functional adaptations between the two breeds of dog, which have been selectively bred for particular purposes. Additionally, in both breeds of dog, we illustrate specialisation of muscle function by spinal region, with differences in both mass and PCSA found between muscles at varying levels of the axial musculoskeletal system, and between muscle functional groups.
