Exam 2 (ch 5,6) Flashcards
deep inside brain; important for horone function and behavior
hypothalamus
once outside the spinal cord, the anterior (motor) and posterior (sensory) roots joint together to form the spinal nerve which passes through the (x)
intervertebral foramen
symptoms: severe headache, sudden hypertension, facial flush, sweating, gooseflesh
autonomic dysreflexia
size of muscles: pectoralis major and minor
large v small
muscle innervation: pronators, wrist and finger flexors on radial side; most thumb muscles; 1st and 2nd lumbricals
median nerve
controls mostly visceral structures
autonomic nervous system
Where does the transition from medulla to spinal cord occur?
foramen magnum
what is this called when there is loss of median nerve?

Pope’s blessing
T1 exits (x) T1 and so on down the vertebral column
under
What muscle is highlighted?

subscapularis; oblique, multipennate muscle
bony defect through which the meninges protrude; little or no nerve damage
meningocele
caused by injury to the common peroneal nerve; commonly caused by pressure to the head of fibula due to a tight cast or bed positioning during periods of prolonged immobility
foot drop
begins at anterior horn of spinal cord; sends motor impulses out of the muscles and receiving sensory impulses from the skin; all nervous tissue outside of the vertebral canal and brainstem
peripheral nervous system
hyperreflexia; serious and potentially life-threatning complication associated with spinal cord injuries at or above T10; usually triggered by noxious stimulus below level of injury
autonomic dysreflexia
unmyelinated fibers; includes the cerebral cortex and central portion of spinal cord
gray matter
fundamental unit of nervous tissue
neuron
point where tendon meets bone
tenoperiosteal junction
clinical motor features of paralysis: loss of elbow flexion, weakened supination
musculocutaneous nerve
each hemisphere is divided into four lobes
lobes
transmit impulses away from the body
axon
purpose of ascending (sensoru) and descending (motor) pathways
carries a particular type of impulse such as touch from and to a specific area
divides into superficial and deep fibular (peroneal) nerves
common fibular nerve
of heads/divisions: sternocleidomastoid
attaches on sternum, mastoid, and clavicle
What muscle is highlighted?

Rectus femoris; oblique, bipennate muscle
