B and C

A,B and C

the length of a muscle

the speed of muscle contraction

involves a disynaptic neural pathway in the CNS

is accompanied by relaxation of antagonist extensor muscles in the contralateral limb

acts on a myotactic unit - all of the muscle acting at a single joint

is present even if the pathways to the brain are not intact

may be produced by noxious stimulation of the skin

The reflex can be evoked in postural muscles.

It is a reflex response to the afferent impulses of tendon organs lying in the tendon being tapped.

This reflex forms the basis for current views about the mechanism of posture.

This reflex involves a chain of two neurones.

It is possible to evoke this reflex by a brisk but light tap on the tendon of the muscle, which then responds with a contraction.

Change in blood pressure at onset of exercise

Withdrawal of the hand after touching a hot stove

Adjustment of muscle tension for a sudden change in muscle load

Change in blood flow to the muscles at onset of exercise

Maintaining a seated (upright) posture
