Which muscle has highest density of muscle spindles?
The muscle with the highest density of muscle spindles is typically the extraocular muscles, which control eye movement. Muscle spindles are sensory receptors that detect changes in muscle length and the rate of that change, playing a crucial role in proprioception and reflexes. Their high density in the extraocular muscles allows for precise control and rapid adjustments necessary for eye coordination and stability.
Richmond lang effect is produced by?
The Richmond Lang effect is produced by the increased firing rate of muscle spindles that occurs when a muscle is subjected to a sudden stretch. This reflex response helps to protect the muscle from potential injury by quickly contracting in response to stretching.
Differences between annulospiral and flower ending?
Afferent innervation in the musclespindle :a) Primary afferent:That forms annulo-spiral endings to the central part of both nuclear bag and nuclear chain intrafusal muscle fibers. They are thick and rapidly conductingb) Seconderyafferent:That forms flower-spray endings on both sides of annulospiral endings in intrafusal muscle fibers. They are thinner and slower in conduction.
How can you measure how hard your heart muscle is working?
Heart rate monitor
What does rate pressure product indicate physiologically?
Rate pressure product indicates the amount of stress being placed on the heart muscle. The measure is taken by multiplying the heart rate with the systolic blood pressure.
Explain the function of stretch receptors in regulating breathing?
The function of the stretch receptors in regulating breathing is to reduce the respiratory rate.
Can rocks stretch?
Rocks can stretch if you apply the force over a long time and the deformation occurs at a very slow strain rate.
Increased return of the blood to the heart stretche's the muscle which does what?
increases the heart rate. ---- Increases the force of contraction, and therefore, the amount of blood pumped out at a time. Think of a rubber band...the more you stretch it, the harder it contracts when you let go.
What is the primary rate limiter for running?
Rate limiters retard or impede development. In running the primary rate limiters are self-organizing, muscle endurance, and muscle strength of each individual.
What is the most useful measure of interest rate?
APR is the most useful measure of interest rate.
What rate does muscle turn to fat without exercise?
Muscle does not turn to fat.
What do stretch marks on your bum mean?
Stretch marks are usually the result of the tissue under the body grows faster than the skin can expand, causing it to stretch. So you might have gained some weight in your bum at a fast rate creating stretch marks.
