Nerve cells in the rabbit cavernous sinus

Twelve rabbits were sacrificed in this research and the cavernous sinuses were taken and processed for ordinary histological stains. Nerve cells were found in the cavernous sinus of all cases alongside the internal carotid artery. These cells were exactly similar to those found in the sympathetic ganglia. These nerve cells may send sympathetic nerve fibres, like the satellite ganglion, around the internal carotid artery

Nerve cells in the three peripheral divisions of trigeminal nerve in albino rat

Ten albino rats were sacrificed in this study. Specimens from the three main division of the trigeminal nerve were prepared and stained with onlinary haematoxylin and eosin, silver and toluidine blue. The distal principal peripheral divisions of the trigeminal nerve were found to contain groups of nerve cells among their nerve fibres. Histologically, these nerve cells were found to be active and similar to the ganglionic cells, hence a new term which is "accessory trigeminal ganglion" can be suggested. These cells were detected in all the sensory divisions: ophthalmic, maxillary and mandibular, and in the motor branch of the mandibular division of the trigeminal nerve as well

Topographical representation of the teeth of the upper jaw in the trigeminal ganglion in cat

Twenty one cats were sacrificed. Three animals were used as a control group. The remaining animals were classified into three groups. The incisors of the upper jaw were extracted from the first group: three animals from their right side and three from their left side. The canines were removed from the second group while the premolars and molars were removed from the last group following the ame numbers and sides as the first group. After 3 weeks, the corresponding trigeminal ganglia were dissected, processed and stained with ordinary haematoxylin and eosin and with silver stain. The topographical representation of the teeth in the trigeminal ganglion was studied. The nerve cells supplying the incisors were found randomly distributed throughout the ganglion but more located in its center. On the other hand, the neurons supplying the canines were found more distributed in the posterior part of the ganglion. while the neurons supplying the premolars and molars were situated anteriorly

Anatomical study of auriculotherapy

Fifteen rabbits were utilized in this study. Surgically induced lesions were done in the stomach, lung, kidney, suprarenal and pancreas. The electrical resistance of the corresponding acupuncture points of the left auricle were measured and recorded before and after the operation. After the operation these points showed marked decrease in theft resistance. This effect can not be demonstrated after injection of local anaesthesia in the auricle. This study confirmed the viewpoint that the body being represented on the auricle and suggested that the effect of auriculotherapy may be due to a nervous mechanism

Correlation between anatomy and acupuncture

Ten cadavers were utilized in this study. Long needles were followed after being inserted in the acupuncture points of the urinary bladder channel on the back of the trunks. These points, which were called Back-Shu points, believed by the Chinese to affect the internal organs. In this research the needles were found either passing through or very close to the sympathetic ganglia of the sympathetic chain. This finding insures the relation of the Bach-Shu points to the internal organs through the medial branches of the sympathetic chain which if stimulated may maintain a balance in the activities of the sympathetic and parasympathetic divisions of the autonomic nervous system

Anatomical study of the intermediate ganglion of the cervical sympathetic chain

40 human cadavers were utilized in this study. The intermediate, ganglion of the cervical sympathetic trunk was studied bilaterally i.e. 80 specimens. The frequency, location and branches of this ganglion were recorded. The frequency of the intermediate ganglion was 23.75% of which the middle cervical ganglion was also present, in the same chain, in 12.50% the intermediate ganglion was more frequently found anterior to the transverse process of the 7th cervical vertebra i.e in 41.25%. The intermediate ganglion gives branches to the larynx, trachea, oesophagus and vascular branches to the adjacent plexuses i.e. Carotied subclavian 6th and 7th cervical nerves to the recurrent laryngcal nerve and to the middle and inferior [or stellate] ganglion
