Cranial Nerves Flashcards
Sensory fibers conduct impulses associated with a sense of smell
I-Olfactory-sensory
Sensory fibers conduct impulses associated with a sense of vision
II- Optic- sensory
Motor fibers conduct impulses to muscles to raise the eyelid move the eye and adjust amount by entering the eye and focus lens. Some sensory fibers conduct impulses associated with proprioceptors
III- Oculomotor- motor
Motor fibers conduct impulses to muscles that move the eyes. Some sensory fibers conduct impulses associated with proprioceptors. Eyes down and medially
IV- Trochlear- motor
Facial expression, sensation, and mastication
V- Trigeminal - mixed
Motor fibers conduct impulses to muscles that move the eyes some sensory fibers conduct impulses associated with proprioreceptors. Eyes laterally
VI- Abducens- motor
Sensory fibers conduct impulses associated with taste receptors of the anterior tongue. Motor fibers conduct impulses of muscles a facial expression tears glands and salivary glands
VII- Facial- mixed
 Hearing and equilibrium
VIII- Vestibulocochlear- sensory
Sensory fibers conduct impulses from the pharynx ,tonsils, posterior tongue, and carotid arteries. Motor fibers conduct impulses to salivary glands and muscles of the pharynx used in swallowing
IX- Glossopharyngeal- mixed
Sensory fibers conduct impulses from the pharynx larynx esophagus and viscera of the thorax and abdomen. Somatic motor fibers conduct impulses to muscles associated with speech and swallowing. Autonomic motor fibers conduct impulses to the viscera of the thorax and abdomen
X- Vagus- mixed
Motor fibers conduct impulses to muscles of the soft palate, pharynx, and larynx. Motor fibers conduct impulses to muscles of the neck and back some proprioceptor input. Shoulder shrugs
XI- Accessory- motor
Motor fibers conduct impulses to muscles that move the tongue some proprioceptor input
XII- Hypoglossal- motor
