Nerves Flashcards
(73 cards)
t/f:
a nerve may consist of sensory or motor nerves
false
nervous system has a built in short cut that takes in the spinal cord between sensory neurons, as it enters the spinal cord and the motor neuron as it leaves the spinal cord. the shorter neuron is called
intercalated neuron
t/f:
the autonomic nervous system is part of the central nervous system
true
how many impairs of spinal nerves
31
division of ANS is for fight or flight
sympathetic nervous system
parasympathetic nerves are referred to as
craniosacral outflow
t/f:gray matter of spinal cord consists of cell bodies of motor neurons
false
divisor of V purely sensory
ophthalmic and maxillary division
t/f:
white matter of spinal cord consists of myelinated axons of both motor and sensory neurons
true
nerve innervates posterior belly of digastric muscle
facial
dorsal root ganglion collection of cell bodies of the sensory neurons entering spinal cord
true
supraorbital notch allows exit of supraorbital nerve, a branch of which division of V
ophthalmic division
muscles of mastication innervated by
V cranial nerve (trigeminal)
t/f:
point where dorsal and ventral roots meet is beginning of spinal nerve
true
nerve supplies max ant teeth
ant sup alveolar nerve
CN only has motor components
VI, abducens nerve
ophthalmic division of V exits skull through
superior orbital fissure
nerve provides taste to ant 2/3 of tongue
VII, facial
posterior superior, middle superior, and anterior superior alveolar nerves branches of
maxillary division (V3)
lesser and greater palatine nerves supply
soft and hard palate
chorda tympani branch of
VII facial
CN provides general sensation to tongue
trigeminal and glossopharyngeal
ANS has motor fibers to
smooth muscle, cardiac muscle, glands
CN has parasympathetic component to lacrimal gland
facial
