What Type Of Receptor Will Sense The Stretching Of The Quadriceps Muscle? (Solved)

The spindles in the quadriceps detect the stretch and send impulses to the spinal cord, and a response is sent back to the muscles resulting in the quadriceps contracting more in order to resist the stretch.

  • Tapping the patellar tendon stretches the quadriceps muscle and causes the sensory receptor of the muscle, called a spindle fiber, to send a signal along the afferent neuron to the spinal cord. This causes the efferent neuron to return a signal to the quadriceps muscle to contract and lift the lower leg.

What sensory receptors detect muscle stretch?

Cutaneous receptors are sensory receptors found in the dermis or epidermis. Muscle spindles contain mechanoreceptors that detect stretch in muscles.

What type of receptor is a stretch receptor?

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. Examples include stretch receptors in the arm and leg muscles and tendons, in the heart, in the colon wall, and in the lungs.

What is the sensory receptor for the stretch reflex?

(A) Diagram of muscle spindle, the sensory receptor that initiates the stretch reflex.

What are the types of stretch receptors?

A receptor that detects stretching in a muscle. There are two main types: Golgi tendon organs at the junction between a muscle and its tendon; and muscle spindle organs in the belly of a muscle.

What are stretch receptors quizlet?

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 are the sensory receptors quizlet?

Sensory receptors are parts of the nervous system that give us information about our external and internal environment. What is the general function of a sensory receptor? The general function of a sensory receptor is to respond to a stimulus and initiate sensory input to the central nervous system.

What are muscle receptors?

The muscle spindle is a remarkable sensory receptor whose supporting structure has a complexity that is often compared to that of the eye. Each spindle consists of a set of specialized muscle fibers called intrafusal fibers embedded within the normal or extrafusal muscle fibers.

What are the sensory receptors?

Sensory receptors are dendrites of sensory neurons specialized for receiving specific kinds of stimuli. Sense organs (such as the eyes and ears) consist of sensory neurons with receptors for the special senses (vision, hearing, smell, taste, and equilibrium) together with connective, epithelial, or other tissues.

What is the stretch receptors used for?

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 stretch reflex reaction?

The stretch reflex (myotatic reflex), or more accurately “muscle stretch reflex”, is a muscle contraction in response to stretching within the muscle. The reflex functions to maintain the muscle at a constant length. When a muscle lengthens, the muscle spindle is stretched and its nerve activity increases.

How does the stretch reflex cause the quadriceps?

The spindles in the quadriceps detect the stretch and send impulses to the spinal cord, and a response is sent back to the muscles resulting in the quadriceps contracting more in order to resist the stretch.

What is the muscle spindle stretch receptor?

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 are the stretch receptors in the muscles called?

Stretch receptors called Golgi tendon organs are found within the collagen fibers of tendons and within joint capsules. They are generally located in series with the muscle rather than the parallel arrangement of the intrafusal muscle fibers.

What are the major types of stretch receptors found in vertebrate muscle and tendons?

In skeletal muscle tissue, these stretch receptors are called muscle spindles. Golgi tendon organs similarly transduce the stretch levels of tendons. Bulbous corpuscles are also present in joint capsules, where they measure stretch in the components of the skeletal system within the joint.
