68wm6 cranial nerves

68wm6 cranial nerves and special senses

anosmia complete or partial loss of sense of smell
anopia absence of an eye
aqueous humor thin, watery fluid that fills the space between the cornea and the iris (anterior chamber)
blepharitis inflammation of the eyelid margins
choroid middle, bascular layer of the eye
cochlea coiled tube in the inner ear
conjunctivitis the transparent front part of the eye that covers the iris, pupil, and anterior chamber
chranial nerve a nerve that arises from the underside of the brain or the brainstem
diplopia double vision
hemianopia blindness in one half of the visual field
iris colored muscular part of the eye
labyrinth complex system of connecting chambers and tubes of the inner ear
lacrimal gland tear gland
sclera tough outer protective layer of the eye
somatic nervous system consists of the cranial and spinal nerve fibers that connect the cns to the skin and skeletal muscles
special senses senses that stem from receptors associated with specialized sensory organs; nose eye, ear, tongue
tympanic membrane eardrum
vitreous humor clear jellylike substance within the eye
the olfactory nerve that is a sensory nerve that carries the sense of smell cranial nerve I
the optic nerve that is a sensory nerve that carries visual signals from the eye to the brain cranial nerve II
the oculomotor nerve is a motor nerve that helps raise eyelid, move the eye upward, toward midline and away from midline, and downward and away from midline, constricts the pupil and focuses the lens cranial nerve III
the trochlear nerve is a motor nerve, helps move the eye downward and away from midline cranial nerveIV
the trigeminal nerve is a mixed nerve that caries sensation from parts of the face and eye, motor impulses to the muscles of mastication cranial nerve V
the abducens nerve is a motor nerve that moves the eye away from the midline cranial nerve VI
the facial nerve is a mixed nerve it carries taste sensation from the tongue and stimulates muscles of facial expression cranial nerve VII
the vestibulocochlear nerve carries sensory information for hearing and equilibrium, cranial nerve VIII
the glossopharyngeal nerve is a mixed nerve, the sensory fibers cary impulses from the lining of the pharynx, tonsils and posterior third of the tongue, motor fibers are responsible for the gag reflex and contols swallowing action cranial nerve IX
the vagus nerve is a mixed nerve, involves both the somatic and autonomic nervous system, somatic motor responsible for swallowing and speech, autonomic control smooth muscles and glands in the thorax and abdomen, cranial nerve X
the hypoglossal nerve, controls muscles that move the tongue (e.g. chewing swallowing and speaking) cranial nerve XII
craial nerves of the eye cranial nerves II, III, IV, VI
