Spinal nerves are the major nerves of the body. A total of 31 pairs of spinal nerves control motor, sensory, and other functions. These nerves are located at the cervical, thoracic, lumbar, sacral, and coccygeal levels.

The Facial Nerve (CN VII)

Spinal Cord Injury Model System. What does the spinal cord do? What is a spinal cord injury? What causes spinal cord injury? What is paralysis? What is paraplegia? What is tetraplegia? What recovery is expected following spinal cord injury? The brain is the command center for your body, and the spinal cord is the pathway for messages sent by the brain to the body and from the body to the brain.

The peripheral nervous system is the network of nerves strands that branch off from the left and right sides of the spinal cord through openings between each vertebra on the spinal canal.

These nerve pairs spread throughout your body to deliver commands from your brain and spinal cord to and from parts of your body. Sensory Functions — monitors sensation of touch, pressure, temperature and pain. There is no cure for SCI but you can learn the potential areas for improvement. Understanding Spinal Cord Injury: What you should know about spinal cord injury and recovery This video uses simple language and images of real people who have sustained a spinal cord injury, as well as medical experts and advocates.

Understanding Spinal Cord Impairments and Functional Goals This 26 minute video offers a basic understanding of the normal function of the spinal cord and the impact of impairment at different types and levels of injury. In addition, functional goals are addressed for levels of impairment.

Spanish Spinal Anatomy Center Feature Articles and Video and Animation Directory from SpineUniverse provides patient and healthcare professional education, providing clear, straightforward information on conditions related to the spine, including degenerative disc disease, spinal stenosis, arthritis, fibromyalgia, and scoliosis.

UAB also encourages applications from individuals with disabilities and veterans.

In this article, we shall look at the anatomy of the facial nerve — its anatomical course, functions and clinical correlations. The facial nerve is associated with the derivatives of the second pharyngeal arch :. The course of the facial nerve is very complex. There are many branches, which transmit a combination of sensory, motor and parasympathetic fibres. The nerve arises in the pons , an area of the brainstem. It begins as two roots; a large motor root , and a small sensory root the part of the facial nerve that arises from the sensory root is sometimes known as the intermediate nerve.

Spinal nerve , in vertebrates, any one of many paired peripheral nerves that arise from the spinal cord. In humans there are 31 pairs: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. Each pair connects the spinal cord with a specific region of the body. Near the spinal cord each spinal nerve branches into two roots. One, composed of sensory fibres , enters the spinal cord via the dorsal root; its cell bodies lie in a spinal ganglion that is outside the spinal cord. The other, composed of motor fibres , leaves the spinal cord via the ventral root; its cell bodies lie in specific areas of the spinal cord itself.

A spinal nerve is a mixed nerve , which carries motor, sensory, and autonomic signals between the spinal cord and the body. In the human body there are 31 pairs of spinal nerves, one on each side of the vertebral column. These are grouped into the corresponding cervical , thoracic , lumbar , sacral and coccygeal regions of the spine. The spinal nerves are part of the peripheral nervous system. Each spinal nerve is a mixed nerve, formed from the combination of nerve fibers from its dorsal and ventral roots. The dorsal root is the afferent sensory root and carries sensory information to the brain.

Brain Made Simple. Spinal nerves are bundles of nerve fibers connected to the spinal cord. These nerves carry information to and away from the spinal cord.

The sciatic nerve is the largest and longest nerve in the human body, originating at the base of the spine and running along the back of each leg into the foot. The sciatic nerve originates in the lower spine and is responsible for motor and sensory functions of the lower body. Watch: Sciatic Nerve Anatomy Video.

 Чед? - В дверях его кабинета возникла Мидж Милкен, эксперт внутренней безопасности Фонтейна. В свои шестьдесят она была немного тяжеловатой, но все еще весьма привлекательной женщиной, чем не переставала изумлять Бринкерхоффа. Кокетка до мозга костей, трижды разведенная, Мидж двигалась по шестикомнатным директорским апартаментам с вызывающей самоуверенностью. Она отличалась острым умом, хорошей интуицией, частенько засиживалась допоздна и, как говорили, знала о внутренних делах АНБ куда больше самого Господа Бога. Черт возьми, - подумал Бринкерхофф, разглядывая ее серое кашемировое платье, - или я старею, или она молодеет.

 - Однажды в колледже Беккер прокатился на мотоцикле и чуть не разбился. Он больше не хотел искушать судьбу, кто бы ни сидел за рулем. - Как скажете.  - Лейтенант направился к двери.  - Я должен выключить свет. Беккер держал коробку под мышкой. Я ничего не упустил.

Только сейчас она поняла, почему он настаивал на том, чтобы ТРАНСТЕКСТ продолжал работать. Если Цифровой крепости суждено стать любимой игрушкой АНБ, Стратмор хотел убедиться, что взломать ее невозможно. - Ты по-прежнему хочешь уйти.

Если мы - охранники общества, то кто будет следить за нами, чтобы мы не стали угрозой обществу. Сьюзан покачала головой, не зная, что на это возразить. Хейл улыбнулся: - Так заканчивал Танкадо все свои письма ко. Это было его любимое изречение.

 - Ты, наверное, не понял.
