After emerging from the vertebral column, what happens to the spinal nerve?
it divides into a large ventral ramus and a smaller dorsal ramus
Except for one cranial nerves serve only the?
Head and neck structures
"And" Abducens nerve (CNVI)
motor nerve, motor to the lateral rectus muscle which moves eye laterally, nerves emerge from the inferior pons
"Oh" Optic nerve (CNII)
Sensory nerve, carries afferent impulses for vision, optic nerves converge to form the optic chiasma and then separates as the optic tracts
"Oh" Oculomotor nerve (CNIII)
Motor nerve, inferior oblique muscle, superior rectus muscles, inferior rectus muscle, medial rectus muscle, and causes pupil constriction and controls lens shape for visual focusing
"To" Trochlear nerve (CNIV)
motor nerve, motor to the superior oblique muscle (depresses the eye and turns to laterally), trochlear emerge from the dorsal surface of the midbrain
"Oh" Olfactory nerve (CNI)
Sensory nerve, carries afferent impulses for the sense of smell, and olfactory bulbs are located on the inferior surface of the frontal lobes
pairs of sacral nerves?
5
"Oh" Oculomotor nerve (CNIII)
Motor nerve, inferior oblique muscle, superior rectus muscles, inferior rectus muscle, medial rectus muscle, and causes pupil constriction and controls lens shape for visual focusing
