- Eighth Or Auditory Nerve
- The auditory nerve consists of two elements, cochlear and vestibular, the fibres of which arise in the internal ear from the spiral and vestibular ganglia respectively. Central Connections (a) C...
- Ninth Or Glosso-Pharyngeal Nerve
- Deep Origin From the dorsal nucleus, nucleus ambiguus and tractus solitarius in the floor of the fourth ventricle, at the back of the medulla. The greater number of the fibres, however, arise from ...
- Tenth Or Vagus Nerve
- Deep Origin Similar to that of the glossopharyngeal nerve, but only a few afferent fibres pass to the tractus solitarius. Superficial Origin Twelve to fifteen rootlets emerge from the medulla...
- Eleventh Or Spinal Accessory Nerve
- The spinal accessory is derived partly from the brain, and partly from the spinal cord. (A) Cerebral Portion. (1) Deep Origin The nucleus ambiguus in the medulla oblongata immediately below the ...
- Twelfth Or Hypoglossal Nerve
- Deep Origin From the grey matter of the floor of the fourth ventricle, and the antero-lateral part of the grey matter around the central canal. The hypoglossal nucleus extends from immediately abov...
- Spinal Nerves
- There are thirty-one pairs of spinal nerves. They are named according to the vertebrae in relation to which they emerge. The thirty-one pairs comprise eight cervical, twelve thoracic, five lumbar, fiv...
- Anterior Primary Divisions Of Spinal Nerves
- The anterior primary divisions are generally much larger than the posterior divisions. Each is connected, near its origin, by one or two filaments, with a ganglion of the sympathetic. With the excepti...
- Brachial Plexus
- The brachial plexus occupies the lower part of the posterior triangle of the neck and the upper part of the axilla. It is formed by the anterior primary divisions of the lower four cervical nerves tog...
- From Lateral And Medial Cords. Median Nerve
- (C. 6, 7, 8, T. 1). The nerve arises from the lateral and medial cords by two heads, the medial of which passes superficially to the third part of the axillary artery to reach its lateral side. It des...
- Thoracic Nerves
- With the exception of the first, the anterior primary divisions of the thoracic nerves do not form plexuses, but extend forwards singly under the name of intercostal nerves. The upper six are termed t...
- Lumbar Plexus
- This plexus is produced by the anterior primary divisions of the first four lumbar nerves, the first being reinforced by a communicating twig from the last thoracic. The fourth lumbar, in addition to ...
- Sacral Plexus
- The sacral plexus occupies the posterior wall of the pelvic cavity, lying on the anterior surface of the piriformis muscle and behind the pelvic fascia. It is formed by the union of the lumbo-sacral c...
- Internal Popliteal
- This is the larger of the two popliteal nerves, and passes down the middle of the popliteal space as far as the lower border of the popliteal muscle, where it becomes the posterior tibial nerve. At fi...
