What Are Stretch Reflex Receptors Called?

Stretch receptors

What are the receptors for the stretch reflex?

A receptor –

muscle spindle

. An afferent fibre – muscle spindle afferent. An integration centre – lamina IX of spinal cord. An efferent fibre – α-motoneurones.

What is another name for stretch reflex receptors?

The stretch reflex (

myotatic reflex

), or more accurately “muscle stretch reflex”, is a muscle contraction in response to stretching within the muscle.

Which reflexes are stretch responses?

The stretch reflex or

myotatic reflex

refers to the contraction of a muscle in response to its passive stretching by increasing its contractility as long as the stretch is within physiological limits.

What is the effector of the stretch reflex?

Stretch Reflex

In this reflex, when a skeletal muscle is stretched,

a muscle spindle in the belly of the muscle is activated

. The axon from this receptor travels to the spinal cord where it synapses with the motor neuron controlling the muscle, stimulating it to contract.

What do stretch receptors do?

muscle systems

…has important sensory structures called stretch receptors, which

monitor the state of the muscle and return the information to the central nervous system

. Stretch receptors are sensitive to the velocity of the movement of the muscle and the change in length of the muscle.

What is the difference between stretch and tendon reflex?

Contrast to stretch reflex

The stretch reflex operates as a feedback mechanism to control muscle length by causing muscle contraction. In contrast, the tendon reflex operates as

a negative feedback mechanism to control muscle tension

. … Like the stretch reflex, the tendon reflex is ipsilateral.

What are the two types of stretches?

Stretches are either dynamic (meaning they involve motion) or static (meaning they involve no motion). Dynamic stretches affect dynamic flexibility and static stretches affect static flexibility (and dynamic flexibility to some degree). The different types of stretching are:

ballistic stretching

.

What is Golgi tendon?

Golgi tendon organs (GTOs) are proprioceptors that are located in the tendon adjacent to the myotendinous junction. … The Golgi tendon organ is a

tree-like sensory ending enclosed in a spindle-like connective tissue capsule

, that lies near the junction of a tendon with a muscle.

Is stretch reflex bad?

The stretch reflex is very important in posture. It helps maintain proper posturing because a

slight lean to either side

causes a stretch in the spinal, hip and leg muscles to the other side, which is quickly countered by the stretch reflex.

What is a simple stretch reflex?

The stretch reflex is also referred to as the deep tendon reflex or myotatic reflex. It is a

simple pre-programmed response by the human body in response to the muscle being passively stretched

e.g. by a tendon hammer, or a sudden change in the ground surface.

What is a tendon reflex?

Tendon reflexes are

single synapse reflexes

. A rapid stretch of the muscle stimulates the muscle spindles and this message is conveyed via the sensory root to the spinal cord at the segmental level of the muscle stimulated.

What is the Golgi tendon organ reflex?

Stretch receptors called Golgi tendon organs are found within the collagen fibers of tendons and within joint capsules. … This reflex, which connects high force in the Golgi tendon organs with relaxation, is the

opposite of

the myotatic reflex, the stretch reflex, in which stretch elicits a reflex contraction.

What is not required for a reflex arc?

A

reflex does not require any thought input

. The path taken by the nerve impulses in a reflex is called a reflex arc. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord.

What is an example of a Polysynaptic reflex?

An example of a polysynaptic reflex arc is seen

when a person steps on a tack

—in response, their body must pull that foot up while simultaneously transferring balance to the other leg.

How can I improve my stretch reflex?

1. Create a strong stretch.
2. Strongly contract the muscle that is stretching and hold for 5 to 30 seconds.
3. Stop contracting stretching muscle.
4. You should feel release in stretching muscle; if so move deeper into pose.
5. Repeat.
