The proprioceptors detect any changes in physical displacement (movement or position) and any changes in tension, or force, within the body. They are found in all nerve endings of the joints, muscles, and tendons. The proprioceptors related to stretching are located in the tendons and in the muscle fibers.

What receptors detect muscle stretch?
Muscle spindles are stretch receptors that signal the length and changes in length of muscles. They lie within an independent capsule, parallel to the main muscle. They are therefore stretched when the muscle lengthens but shorten when the muscle contracts.
What sensory receptor is used in the stretch reflex?
(A) Diagram of muscle spindle, the sensory receptor that initiates the stretch reflex.
What are muscle stretch reflexes?
The stretch reflex or myotatic reflex refers to the contraction of a muscle in response to its passive stretching. When a muscle is stretched, the stretch reflex regulates the length of the muscle automatically by increasing its contractility as long as the stretch is within the physiological limits.
What are stretch receptors?
Stretch receptors are mechanoreceptors responsive to distention of various organs and muscles, and are neurologically linked to the medulla in the brain stem via afferent nerve fibers.
What are stretch receptors quizlet?
Terms in this set (5) Name two types of stretch receptors. Spindle cells and Golgi tendons. They warn of the danger of a muscle and/or tendon tearing when too much force is exerted on the muscle. They signal the muscle to relax.
What controls the stretch reflex?
When a muscle lengthens, the muscle spindle is stretched and its nerve activity increases. A secondary set of neurons also causes the opposing muscle to relax. Gamma motoneurons regulate how sensitive the stretch reflex is by tightening or relaxing the fibers within the spindle.
Are sensory receptors that detect stretch in skeletal muscles tendons and joints?
Sensory receptors located in the inner ear, muscles, tendons, and joints that use internal stimuli to detect changes in position or movement of the body or its limbs are called proprioceptors.
What causes a stretch reflex?
The stretch reflex is activated (or caused) by a stretch in the muscle spindle. When the stretch impulse is received a rapid sequence of events follows. The motor neuron is activated and the stretched muscles, and its supporting muscles, are contracted while its antagonist muscles are inhibited (relaxed).
What is passive stretching?
Passive stretching is a technique in which you are relaxed and make no contribution to the range of motion. Instead, an outside agent creates force, either manually or mechanically. Examples include using a towel, band, gravity or another person to help you stretch.
What is a stretch reflex example?
For example, this reflex occurs is when a person is standing in an upright position then begins to lean on one side. Some of the stretch reflexes are jaw jerk reflex, biceps reflex, brachioradialis reflex, triceps reflex, patellar reflex, and ankle jerk reflex. Synonyms: myotatic reflex.
What are stretch receptor used for?
Stretch receptors are essential for coordinated muscle activity, passing information about the state of muscles to the central nervous system (see kinaesthesis).
What is responsible for signaling the activation of the stretch receptors?
They can be activated by either stretch or muscle contraction. Golgi tendon organs signal the force that develops in the tendon on muscle contraction, whereas muscle spindles provide feedback about the amount and rate of muscle stretch.
What do stretch receptors in the heart do?
Special pressure sensors called baroreceptors (or venoatrial stretch receptors) located in the right atrium of the heart detect increases in the volume and pressure of blood returned to the heart. These receptors transmit information along the vagus nerve (10th cranial nerve) to the central nervous system.
