41Cranial nerve VI — The sixth cranial nerve is the abducent nerve. It is a small motor nerve that has one task: to supply a muscle called the lateral rectus muscle that moves the eye outward. Paralysis of the abducent nerve causes inward turning of the eye (internal …
42Cranial nerve VII — The cranial nerves emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column. There are twelve cranial nerves. The facial nerve is the seventh cranial nerve. The facial nerve supplies the …
43Cranial nerve XI — The eleventh cranial nerve is the accessory nerve. The twelve cranial nerves, the accessory nerve included, emerge from or enter the skull (the cranium) as opposed to the spinal nerves which emerge from the vertebral column. The accessory is so… …
44Cranial nerve, eleventh — The eleventh cranial nerve is the accessory nerve. The twelve cranial nerves, the accessory nerve included, emerge from or enter the skull (the cranium) as opposed to the spinal nerves which emerge from the vertebral column. The accessory is so… …
45Cranial nerve, fifth — The fifth cranial nerve is the trigeminal nerve. The trigeminal nerve is quite complex. It functions both as the chief nerve of sensation for the face and the motor nerve controlling the muscles of mastication (chewing). Problems with the sensory …
46Cranial nerve, first — The cranial nerves emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column. There are twelve cranial nerves. The first cranial nerve is the olfactory nerve which carries impulses for… …
47Cranial nerve, second — The second cranial nerve is the optic nerve, the nerve that connects the eye to the brain and carries the impulses formed by the retina the nerve layer that lines the back of the eye, senses light and creates the impulses to the brain which… …
48Cranial nerve, sixth — The sixth cranial nerve is the abducent nerve. It is a small motor nerve that has one task: to supply a muscle called the lateral rectus muscle that moves the eye outward. Paralysis of the abducent nerve causes inward turning of the eye (internal …
49Cranial nerve, third — The third cranial nerve is the oculomotor nerve. The cranial nerves emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column. There are twelve cranial nerves. The oculomotor nerve is… …
50cranial nerve — Anat. any of the nerves arising from the brainstem and exiting to the periphery of the head through skull openings, including 10 pairs in fish and amphibians and 12 pairs in reptiles, birds, and mammals: in humans, these are the abducens nerve,… …
