The myotatic reflex is provoked by activation of muscle spindles in a stretched muscle. These muscle spindles are sensory receptors that detect changes in muscle length and help regulate muscle contraction and body position. When a muscle is stretched, the muscle spindles send signals to the spinal cord, leading to a reflex contraction to prevent overstretching.

What is an injury caused by a muscle being overstretched?
An injury caused by a muscle being overstretched is called a muscle strain. It occurs when the muscle fibers are stretched beyond their normal limits, leading to tearing of the muscle fibers. Common symptoms include pain, swelling, and reduced range of motion.
What is an injury to a muscle or tendon?
An injury to a muscle or tendon is typically referred to as a strain or a sprain. A strain occurs when a muscle is stretched or torn, while a sprain occurs when a ligament is stretched or torn. These injuries can range from mild to severe, leading to pain, swelling, and reduced function in the affected area.
What is another name for a muscle pull?
Another name for a muscle pull is a muscle strain. It occurs when muscle fibers are stretched or torn, usually due to overexertion or sudden movements. Symptoms include pain, swelling, and limited range of motion.
What is excitation coupling and list the process?
Excitation coupling is the process by which an action potential in a muscle cell triggers the release of calcium ions from the sarcoplasmic reticulum, leading to muscle contraction. The steps of excitation coupling in muscle cells involve depolarization of the cell membrane, activation of voltage-gated calcium channels, release of calcium ions from the sarcoplasmic reticulum, and activation of the contractile proteins within the muscle cell.
List the Basic steps of simple reflex arc like the stretch reflex?
Muscle stretch: When a muscle is stretched, sensory receptors called muscle spindles detect the change in length. Sensory neuron activation: The muscle spindles send a signal through sensory neurons to the spinal cord. Motor neuron activation: In the spinal cord, the sensory neuron synapses with a motor neuron, which sends a signal back to the muscle causing it to contract in response to the stretch.
What tissue can contract and be stretched but not expand?
muscle
When a muscle pulls what happens?
you have then stretched your tendon / muscle beyond the normal range .
What are the injuries found in a muscle strain?
A strain is a torn or stretched muscle or tendon.
When the arm is stretched the biceps muscle will become?
LENGTHENED
A strain is an injury in which a muscle?
Over stretched or torn
What injury occurs when a muscle is over stretched?
CRAMPS
What happens to muscle force production when the muscle is too short?
Force produced is reduced, when the muscle is over-stretched or under-stretched it is weaker. Most muscles will produce max force at roughly 90 degrees.
When a muscle is stretched by a contraction of the opposing muscle it is called?
if you're on OdysseyWare your answer would be Active stretching.............. =)
When a muscle is suddenly stretched what is called to action?
Stretch Reflex
What muscle do you stretch when you do the butterfly stretch?
Your groin is being stretched.
What activity is musicle spindle?
A muscle spindle tightens when the muscle is stretched too far too fast to prevent damage to the muscle.
What are two proprioceptors that tell how much and how fast a muscle is being stretched?
Golgi tendon Muscle spindles
