Coenzyme Q10 is a vitamin-like substance used in the treatment of a variety of disorders primarily related to suboptimal cellular energy metabolism and oxidative injury.
Cranial Nerves: OLFACTORY (1) NERVE. - this nerve is entirely sensory, it contains axons that conduct nerve impulses for olfaction, the sense of smell. - bundles of axons of olfactory receptors extend through foramina in the cribiform plate of the ethmoid bone.ROCHLEAR (4) NERVE. - is a motor cranial nerve. It is the smallest of the 12 cranial nerves and is the only one that arises from the posterior aspect of the brain stem. - the somatic motor fibers innervate the superior oblique muscle of the eyeball.
They share many similarities with peripheral nerves that emerge from the spinal cord. Most cranial nerves exit the central nervous system (CNS) at the level of the brainstem (Fig. 14-1). Two cranial nerves (i.e., the olfactory [I] and optic [II]) enter the CNS at the level of the forebrain.Only one cranial nerve, the accessory nerve (cranial nerve [CN] XI), does not emerge from the brain.4-1). Two cranial nerves (i.e., the olfactory [I] and optic [II]) enter the CNS at the level of the forebrain. Only one cranial nerve, the accessory nerve (cranial nerve [CN] XI), does not emerge from the brain.
