AK Anatomy & Physiology Fundamentals 2

Question 1

Which proprioceptive receptor is primarily responsible for detecting changes in muscle length and triggering the stretch reflex?

Accepted Answer

Muscle spindle

Answer

Muscle spindles are intrafusal fibers sensitive to muscle length changes and initiate the monosynaptic stretch reflex arc.

Question 2

In Applied Kinesiology, the neurolymphatic reflex points associated with the pectoralis major clavicular muscle are located on which structure?

Accepted Answer

Sternum

Answer

Chapman's neurolymphatic reflex points for the pectoralis major clavicular are found on the sternum and are used to evaluate stomach function.

Question 3

The Golgi tendon organ (GTO) responds primarily to:

Accepted Answer

Tension developed during active contraction

Answer

GTOs are located at the musculotendinous junction and fire in response to muscle tension, particularly during active contraction, triggering autogenic inhibition.

Question 4

Which cranial nerve provides motor innervation to the sternocleidomastoid and trapezius muscles?

Accepted Answer

CN XI (Accessory)

Answer

The spinal accessory nerve (CN XI) provides motor innervation to both the sternocleidomastoid and the trapezius muscles.

Question 5

In AK muscle testing, a facilitated muscle that tests strong is most consistent with which finding?

Accepted Answer

Hypertonicity or over-facilitation of that muscle

Answer

A facilitated (hypertonic) muscle tests strong but represents an abnormal neurological state of over-excitability that can accompany dysfunction.
