The muscle spindle detects excessive stretch within the muscle?
True
What structure detects the amount of stretch or tension in skeletal muscles tendons and joint's?
Proprioceptors
What is past participle of stretch?
"Stretch" is a regular verb; therefore, the past participle is "stretched".
What is the Name of the receptor for the stretch reflex?
The receptor for the stretch reflex is called the muscle spindle. Muscle spindles are sensory receptors located within the belly of muscles, and they detect changes in muscle length and the rate of that change. When a muscle is stretched, the muscle spindle initiates the stretch reflex, leading to a contraction of the muscle to resist the stretch. This reflex helps maintain posture and balance.
Which does not belong cutaneous receptors free dendritic endings stretch pain and touch?
Free dendritic endings do not belong as they are a type of nerve ending located in connective tissue that detects pain and temperature changes, whereas the other options are types of cutaneous receptors that detect touch, stretch, and pain.
Which ligament of the initiates the knee jerk reflex when tapped?
The patellar ligament initiates the knee jerk reflex when tapped. When the patellar tendon is tapped just below the patella, the sensory neurons detect the sudden stretch and send an impulse to the spinal cord. This reflex causes the contraction of the quadriceps muscles, resulting in the extension of the leg.
What is a type of receptor that responds to changes in stretch of skeletal muscle and initiates a stretch reflex?
Muscle spindle receptors which are located in the belly's of muscles measure length of stretch and speed of change. They send this afferent neural information to the posterior horn of the spinal cord where and interneuron interprets the information and if the stretch is ballistic (if it changes length too rapidly) it will trigger an efferent motor unit, or many motor units, through the anterior horn of the spinal cord to contract the muscle.
Why does the muscle cell have a long shape?
The cell is long because the , muscle needs to stretch and contract when you use that muscle. Therefore it needs to be long in order to stretch.
When does the activation of a motor neuron occur in a stretch flex?
The activation of a motor neuron in a stretch reflex occurs when a muscle spindle detects a quick stretch in a muscle. This sensory information is relayed to the spinal cord, where it synapses with the motor neuron corresponding to the stretched muscle. The motor neuron is then activated, causing the muscle to contract and counteract the stretch, leading to the reflexive response. This process happens rapidly, often without conscious thought, to protect the muscle from excessive stretching.
Sensory receptors found in muscle and tendons that detect their degree of stretch?
the muscle spindle detects it, and causes reflexes that automatically make slight alterations to muscle tentions, so that you stand up right.
Is it ok to stretch without warm up if the weather is hot and your body is warm already?
Stretching is warming up. Therefore, it is OK to stretch if the weather is hot and body is already warm.
What are the neural circuits in the spinal cord?
Central pattern generators are one type of circuit. These are related to compound muscle activation. Stretch and inverse stretch reflexes are other kinds of circuits that, respectively, contract or relax muscles upon lengthening. Another kind of circuit is the withdrawl reflex, which protects limbs from noxious stimuli.
