OBJECTIVE The purpose of this study was to determine if diagnostic and therapeutic procedures for the cervical and cranial spine taught to students during the undergraduate program at Canadian Memorial Chiropractic College are required to be used during their internship by their supervising clinicians and, if so, to what extent these procedures are used. METHODS Course manuals and course syll...

This study was performed to reveal the anatomy of the cervical canal in Angora goats. For this purpose, sixty genital tracts of adult Angora goats in estrus, weighing from 40 to 50 kg, obtained from Konya slaughterhouses, were used. The materials were examined by dissection and latex cast techniques. In dissections, the vaginal protrusions were star, duckbill, crescent, spiral, cluster and bump...

Administration of 6-hydroxydopamine to adult rats results in changes in the superior cervical ganglion similar to those noted after axotomy; namely, a decrease in muscarinic receptor binding and increases in activities of the oxidative enzymes of the pentose phosphate pathway. These changes were either prevented or attenuated markedly by the systemic administration of nerve growth factor. Admin...

Changes in cochlear microphonics (CM) were observed by the injection f vegetative stimulants into the abdominal cavity, by the application f nicotine to the superior cervical ganglion, and by excision or electric stimulatian of the cervical sympathetic nerve and vagus nerve on guinea-pigs. 1) C. M. is reduced by the injection fatropine and acetylcholine while it is induced at the biginnig and t...

A 60-year-old male patient was evaluated for cervical pain, hiccups, dysphonia and dysphagia for five months. Physical examination showed left IX and X cranial nerve palsy. Brain MRI was normal. A cervical CT scan showed an elongated styloid process and stylohyoid ligament pseudoarthrosis (Figure). Eagle’s syndrome is a rare entity caused by abnormal enlargement and ossification of the styloid ...

BACKGROUND AND OBJECTIVES Recent studies showed that, in addition to parasympathetic nerves, cervical vagal nerves contained significant sympathetic nerves. We hypothesized that cervical vagal nerve stimulation (VNS) may capture the sympathetic nerves within the vagal nerve and activate the stellate ganglion. MATERIALS AND METHODS We recorded left stellate ganglion nerve activity (SGNA), left...

Fractures of the occipital condyle are rare. Their prompt diagnosis is crucial since there may be associated cranial nerve palsies and cervical spinal instability. The fracture is often not visible on a plain radiograph. We report the case of a 21-year-old man who sustained an occipital condylar fracture without any associated cranial nerve palsy or further injuries. We have also reviewed the l...

The neurotrophic factors that influence the development and function of the parasympathetic branch of the autonomic nervous system are obscure. Recently, neurturin has been found to provide trophic support to neurons of the cranial parasympathetic ganglion. Here we show that GDNF signaling via the RET/GFR(alpha)1 complex is crucial for the development of cranial parasympathetic ganglia includin...

To delineate the anomaly and frequency of their occurrence in a pig model, we reported the topography of the vagus laryngeal branches and compared the differences with humans. Thirty sides of cervical vagus nerve in 15 fresh cadavers (Sus scrofa) were microdissected. We measured the branch diameters and lengths of the laryngeal branches using a Vernier caliper with a resolution of 0.01 mm. Two ...
