SKELETAL MUSCLE REFLEXES

Question 1

a specific response to a specific stimulus

Answer 1

reflex

Question 2

this is a receptor that is stimulated by the stretch of a skeletal muscle fiber (extrafusal skeletal muscle)

Answer 2

muscle spindle (intrafusal skeletal muscle)

Question 3

the elongated portion of the spindle running parallel to the nuclear bag, monitors the chain in length of the muscle fiber (static activity)

Answer 3

nuclear chain

Question 4

the beginning of the I, fiber surrounding the nuclear bag and the nuclear chain

Answer 4

annulospiral

Question 5

afferent nerve fibers specifically from the annulospiral of muscle spindle synapses on alpha motorneurons

Answer 5

type I fibers

Question 6

the afferent fibers from the trailing ends of the muscle spindle monitor changes in muscle fiber length (static)

Answer 6

type II fibers

Question 7

innervate the skeletal muscle fibers directly

Answer 7

alpha motorneuron

Question 8

innervates the muscle spindle fiber directly, receives information from the descending pathways, regulates spindle sensitivity and muscle tonus

Answer 8

gamma motoneurons
