Human Anatomy and Physiology Chapter 13 Study Guide Notecards
The patellar "knee jerk" reflex is an example of a
stretch reflex
The cervical nerve is not a branch of the
trigeminal nerve
The phrenic nerve does not arise from the
brachial plexus
Sensory receptors are classified by
type of stimulus detected, location in the body, and structural complexity.
The posterior side of the thigh, leg, and foot is served by the
tibial nerve
Starting at the spinal cord, the subdivisions of the brachial plexus are (in order):
roots, trunks, divisions, and cords.
The cranial nerve with a cervical origin (spinal cord) is
the accessory
A major nerve of the lumbar plexus is
the femoral
Spinal nerves exiting the cord from the level of L4 to S4 form the
sacral plexus
Inborn or intrinsic reflexes are involuntary, yet may be modified by
learned behavior
Visceral identification is not an aspect of
sensory perception
Striking the "funny bone" is actually stimulation of (or injury to) the
ulnar nerve
A reflex that causes muscle relaxation and lengthening in response to muscle tension is called a
tendon reflex
Pressure, pain, and temperature receptors in the skin are
exteroceptors
Potentially damaging stimuli that result in pain are selectively detected by
nociceptors
Pressure receptors
adapt most slowly
Nerves that carry impulses toward the CNS only are
afferent nerves
After axonal injury, regeneration in peripheral nerves is guided by
Schwann cells
Regeneration within the CNS is prevented due to
growth-inhibiting proteins of oligodendrocytes.
In a crossed-extensor reflex
if the right arm was grabbed it would flex and the left arm would extend.
Pattern recognition allows us
to see a familiar face
All processing at the circuit level going up to the perceptual level must
synapse in the thalamus.
The sciatic nerve is a combination of two nerves
common fibular and tibial
The median nerve is compressed in
carpal tunnel syndrome
Bell's palsy is characterized by
paralysis of facial muscles
Receptor, afferent neuron, integration center, efferent neuron, effector is
the correct simple spinal reflex arc.
Mixed cranial nerves containing both motor and sensory fibers include
all oculomotor, trigeminal and facial nerves.
Transduction refers to
conversion of stimulus energy into energy of a graded potential.
The flexor muscles in the anterior arm (biceps brachii and brachialis) are innervated by the
musculocutaneous nerve
The cranial nerves that have neural connections with the tongue include all except the
trochlear
Problems in balance may follow trauma to the
vestibulocochlear nerve
A fracture of the ethmoid bone could result in damage to
the olfactory nerve
Ganglia associated with afferent nerve fibers contain
cell bodies of sensory neurons
A fall or an improperly delivered gluteal injection could result in
sciatica
Feeling a gentle caress on your arm would likely involve all of the following except
Pacinian corpuscles.
