1

The patellar "knee jerk" reflex is an example of a

stretch reflex

2

The cervical nerve is not a branch of the

trigeminal nerve

3

The phrenic nerve does not arise from the

brachial plexus

4

Sensory receptors are classified by

type of stimulus detected, location in the body, and structural complexity.

5

The posterior side of the thigh, leg, and foot is served by the

tibial nerve

6

Starting at the spinal cord, the subdivisions of the brachial plexus are (in order):

roots, trunks, divisions, and cords.

7

The cranial nerve with a cervical origin (spinal cord) is

the accessory

8

A major nerve of the lumbar plexus is

the femoral

9

Spinal nerves exiting the cord from the level of L4 to S4 form the

sacral plexus

10

Inborn or intrinsic reflexes are involuntary, yet may be modified by

learned behavior

11

Visceral identification is not an aspect of

sensory perception

12

Striking the "funny bone" is actually stimulation of (or injury to) the

ulnar nerve

13

A reflex that causes muscle relaxation and lengthening in response to muscle tension is called a

tendon reflex

14

Pressure, pain, and temperature receptors in the skin are

exteroceptors

15

Potentially damaging stimuli that result in pain are selectively detected by

nociceptors

16

Pressure receptors

adapt most slowly

17

Nerves that carry impulses toward the CNS only are

afferent nerves

18

After axonal injury, regeneration in peripheral nerves is guided by

Schwann cells

19

Regeneration within the CNS is prevented due to

growth-inhibiting proteins of oligodendrocytes.

20

In a crossed-extensor reflex

if the right arm was grabbed it would flex and the left arm would extend.

21

Pattern recognition allows us

to see a familiar face

22

All processing at the circuit level going up to the perceptual level must

synapse in the thalamus.

23

The sciatic nerve is a combination of two nerves

common fibular and tibial

24

The median nerve is compressed in

carpal tunnel syndrome

25

Bell's palsy is characterized by

paralysis of facial muscles

26

Receptor, afferent neuron, integration center, efferent neuron, effector is

the correct simple spinal reflex arc.

27

Mixed cranial nerves containing both motor and sensory fibers include

all oculomotor, trigeminal and facial nerves.

28

Transduction refers to

conversion of stimulus energy into energy of a graded potential.

29

The flexor muscles in the anterior arm (biceps brachii and brachialis) are innervated by the

musculocutaneous nerve

30

The cranial nerves that have neural connections with the tongue include all except the

trochlear

31

Problems in balance may follow trauma to the

vestibulocochlear nerve

32

A fracture of the ethmoid bone could result in damage to

the olfactory nerve

33

Ganglia associated with afferent nerve fibers contain

cell bodies of sensory neurons

34

A fall or an improperly delivered gluteal injection could result in

sciatica

35

Feeling a gentle caress on your arm would likely involve all of the following except

Pacinian corpuscles.
