Question 1

basic functional unit

Answer 1

reflex arc

Question 2

simple neuronal pathways-sensory neurons synapse directly with motor neurons

Answer 2

monosynaptic reflex

Question 3

complex pathways and integrative centers-one or more interneurons

Answer 3

polysynaptic reflex

Question 4

muscles contract in response to a stretching force applied

Answer 4

stretch reflex

Question 5

muscle spindle

Answer 5

sensory receptor (specialized skeletal muscle fibers)

Question 6

motor neurons-innervate fibers (small axon)

Answer 6

gamma motor neurons

Question 7

motor neurons in spinal cord synapse with sensory neurons (large axon)

Answer 7

alpha motor neurons

Question 8

Golgi tendon reflex

Answer 8

prevents contracting muscles from applying excessive tension on tendons

Question 9

Golgi tendon organs

Answer 9

encapsulated nerve endings- located near muscle-tendon junction

Question 10

withdrawal reflex

Answer 10

flexor reflex- to remove a limb or other body part from a painful stimulus

Question 11

reinforces the efficiency of the withdrawal reflex

Answer 11

reciprocal innervation

Question 12

crossed extensor reflex

Answer 12

shifts weight of body to prevent falls
