the Ia fibres of the muscle spindles
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.
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.
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.
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.
receptor: initiate impulse: receive something sensory neuron: will carry impulse from receptors to the central nervous system motor neuron: tranmits impulse away from central nervous system into effector internuncial neuron: carry impulse from pre- synaptic to post synaptic effector: muscles or glands

you have then stretched your tendon / muscle beyond the normal range .
A strain is a torn or stretched muscle or tendon.
Over stretched or torn
CRAMPS
LENGTHENED
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.
if you're on OdysseyWare your answer would be Active stretching.............. =)
Your groin is being stretched.
Stretch Reflex
A muscle spindle tightens when the muscle is stretched too far too fast to prevent damage to the muscle.
