The Myotatic Reflex Is a MonoSynaptic Reflex Between Ia Afferents and the α Motor Neuron. The myotatic reflex is the “knee-jerk” reflex in which a muscle contracts in direct response to its stretch.
Which reflexes are stretch reflexes?
- Jaw jerk reflex (CN V)
- Biceps reflex C5/C6.
- Brachioradialis reflex C6.
- Extensor digitorum reflex C6/C7.
- Triceps reflex C7/C8.
- Patellar reflex L2-L4 (knee-jerk)
- Ankle jerk reflex S1/S2.
What receptors initiate the stretch reflex?
As already mentioned, the sensory signal for the stretch reflex originates in muscle spindles, sensory receptors embedded within most muscles (see previous section and Chapter 9).
What is dynamic stretch reflex and static stretch reflex?
The static component of the stretch reflex is in place as long as the muscle is stretched. The dynamic phase occurs only when the muscle is stretched e.g. when the tendon is struck with a tendon hammer. When the muscle is stretched, they send an impulse via the sensory neurons to the relevant spinal cord segment.
What does dynamic stretching do?
Dynamic stretches are active movements where joints and muscles go through a full range of motion. They can be used to help warm up your body before exercising. Dynamic stretches can be functional and mimic the movement of the activity or sport you're about to perform.
What is not a safe way to incorporate stretching?
Bouncing while stretching Bouncing is counterproductive as it can cause small tears to the muscle tissue, which are experienced as muscle soreness or tenderness. Instead of 'bouncing, try: concentrating on slow, sustained stretches. holding the stretch for 10 to 20 seconds.
