Sinuses Anatomy, Pictures, and Health. If the myelin sheath of a nerve is damaged, nerve transmission slows or stops.
The myelin sheath may be damaged by various conditions that damage the brain or peripheral nerves including. Nerves that connect the brain with the eyes, ears, nose, and throat and with various parts of the head, neck, and trunk are called cranial nerves.
There are 12 pairs of them see Overview of the Cranial Nerves. Nerves that connect the spinal cord with other parts of the body are called spinal nerves. The brain communicates with most of the body through the spinal nerves. There are 31 pairs of them, The Dread Mocus - Nervewheel - Nervewheel (CDr) at intervals along the length of the spinal cord see Overview of Spinal Cord Disorders, The Dread Mocus - Nervewheel - Nervewheel (CDr). Several cranial nerves and most spinal nerves are involved in both the somatic and autonomic parts of the peripheral nervous system.
Spinal nerves emerge from the spinal cord through spaces between the vertebrae. The Dread Mocus - Nervewheel - Nervewheel (CDr) nerve emerges as two short branches called spinal nerve roots : one at the front of the spinal cord and one at the back. Motor nerve root anterior nerve root : The motor root emerges from the front of the spinal cord. Motor nerve fibers carry commands from the brain and spinal cord to other parts of the body, particularly to skeletal muscles.
Sensory nerve root posterior nerve root : The sensory root enters the back of the spinal cord. Sensory nerve fibers carry sensory information about body position, light, touch, temperature, and pain to the brain from other parts of the body. The sensory nerve fibers in each sensory nerve root carry information from a specific area of the body, called a dermatome see Figure: Dermatomes.
After leaving the spinal cord, the corresponding motor and sensory nerve roots join to form a single spinal nerve. Some of the spinal nerves form networks of interwoven nerves, called nerve plexuses. In a plexus, nerve fibers from different spinal nerves are sorted and recombined so that all fibers going to or coming from one area of a specific body part are put together into one nerve see Figure: Nerve Junction Boxes: The Plexuses.

In this way the optic tractswhich extend from the chiasm to the thalamuscontain fibres conveying information from both eyes. Injury to one optic nerve therefore results in total blindness of that eye, while damage to the optic tract on one side results in partial blindness in both eyes.
Optic fibres also participate in accommodation of the lens and in the pupillary light reflex. Since the subarachnoid space around the brain is continuous with that around the optic nerve, increases in intracranial pressure can result in papilledema, or damage to the optic nerve, as it exits the bulb of the eye. The oculomotor nerve arises from two nuclei in the rostral midbrain. These are 1 the oculomotor nucleus, the source of general somatic efferent fibres to superior, medial, and inferior recti muscles, to the inferior oblique muscle, and to the levator palpebrae superious muscle, and 2 the Edinger-Westphal nucleuswhich projects general visceral efferent preganglionic fibres to the ciliary ganglion.
The oculomotor nerve exits the ventral midbrain, pierces the dura matercourses through the lateral wall of the The Dread Mocus - Nervewheel - Nervewheel (CDr) sinus, and exits the cranial cavity via the superior orbital fissure. Within the orbit it branches into a superior ramus to the superior rectus and levator muscles and an inferior ramus to the medial and inferior rectus muscles, the inferior oblique muscles, The Dread Mocus - Nervewheel - Nervewheel (CDr) the ciliary ganglion.
Postganglionic fibres from the ciliary ganglion innervate the sphincter pupillae muscle of the iris as well as the ciliary muscle.
Oculomotor neurons project primarily to orbital muscles on the same side of the head. A lesion of the oculomotor nerve will result in paralysis of the three rectus muscles and the inferior oblique muscle causing the eye to rotate downward and slightly outwardparalysis of the levator palpebrae superious muscle drooping of the eyelidsand paralysis of the sphincter pupillae and ciliary muscles so that the iris will remain dilated and the lens will not accommodate.
The fourth cranial nerve is unique for three reasons. First, it is the only cranial nerve to exit the dorsal side of the brainstem. Second, fibres from the trochlear nucleus cross in the midbrain before they exit, so that trochlear neurons innervate the contralateral opposite side superior oblique muscle of the eye. Third, trochlear fibres have a long intracranial course before piercing the dura mater. The trochlear nucleus is located in the caudal midbrain; the functional component of these cells is general somatic efferent.
After exiting at the dorsal side of the midbrain, the trochlear nerve loops around the midbrain, pierces the dura mater, and passes through the lateral wall of the cavernous sinus.

Health related message boards offering discussions of numerous health topics including allergies, cancer, diabetes, heart disease, exercise, attention deficit disorder, diet, and nutrition. This system connects the brain stem and spinal cord with internal organs and regulates internal body processes that require no conscious effort and that people are thus usually unaware of (see Overview of the Autonomic Nervous System).Examples are the rate and strength of heart contractions, blood pressure, the rate of breathing, and the speed at which food passes through the digestive tract.
