Palsies of Cranial Nerves That Control Eye MovementMichael Rubin, MDCM
Abducens: Associated with muscle movement. The abducens nerve controls another eye muscle (lateral rectus muscle) that allows for outward eye movements such as looking to either side. Facial: Associated with muscle movement and collecting information. The facial nerve takes information from your taste ...
Cranial nerves supply sensory and motor information to structures of the head and neck, controlling the activity of this region. Only the vagus nerve extends beyond the neck, to innervate thoracic and abdominal viscera. We’re sure that while reading textbooks, you encountered with terms such as...
symmetrically arranged so that they are distributed mainly to the structures of the head and neck. The one exception is thevagus nerve, which extends down to serve structures in the chest and abdomen. Some of the cranial nerves are both sensory and motor (controlling motion as well as conducti...
Along with the oculomotor nerve (CN III) and the trochlear nerve (CN IV), it is a purely motor nerve responsible for controlling movement of the eyeball. Similar to oculomotor and trochlear nerves, the abducens nerve attributes its name to its function. It supplies the muscle (lateral rectus...
Cranial nerves III, IV and V are motor nerves and are responsible for the movement of the human eye. CN III, better known as the oculomotor nerve, is perhaps the most important of the three. The oculomotor nerves originate in the oculomotor nucleus in the midbrain and separate into superior...
(e) Terminal nerve GnRH3 cells arise from the premigratory cranial neural crest [48,63]. (f) Midbrain GnRH2 cells are proposed to arise from the cranial neural crest [63]. Part (c) is modified (from the cover of the issue in which Ref. [67] appears), with permission, from the ...
4. Trochlear Nerve.This is also a motor neuron that aids in eye movement. 5. Trigeminal Nerve.This is the largest of the cranial nerves. It's both a sensory and a motor nerve and aids in sensory feelings like touch and pain in the face (cheeks, lips, scalp, eyelids, head, etc) an...
Cranial Nerve VII (The Facial Nerve) Anatomy of Cranial Nerve VII (Facial Nerve) Cranial nerve VII (the facial nerve) (Fig. 10.1) is a mixed nerve with both motor and sensory components. Fibers from the motor division supply the facial mimetic musculatur
Trigeminal placode cells differentiate into sensory neurons of cranial nerve V and innervate the sensory apparati in the muscles of the eye region, upper and lower jaw, as well as the tongue (Gillig and Sanders, 2010). Based on our results above revealing truncated to absent outgrowth of proc...
