contracted muscle and relaxed muscle whats are the difference?
contracted muscle means its very very contracted
and relaxed muscle means its very very relaxed
one would be the amount of contractile strength that results from a muscle contraction.
i don't no what is the answer?
This question is confusing. Are you asking if you see only a relaxed muscle fiber in EMs? Yes, you would only see that, not a contracted muscle fiber. The preparation could only be of a relaxed fiber.
Yes, the ciliary muscle is relaxed for distant vision, but is contracted for close vision.
What are the events that influence the width of each of sarcomere when a muscle being contracted and relaxed
The ciliary muscle is relaxed when you look at something that is far away.
The opposite of extended (moved out) could be retracted (moved in). The opposite of extended (relaxed, as with a muscle) is contracted.
Yes. If not, the action at the joint will be incomplete and dysfunctional. As a whole, a muscle fiber is either contracted or relaxed (the all-or-none principal).
We mostly talk about agonists and antagonists with regards to cellular receptors. An agonist binds to a receptor and activates it, an antagonist binds to the receptor, but DOES NOT activate it, and prevents it from being activated.
Systole and diastole describe the phase/state the heart is in during a heartbeat. Systole refers to the heart when contracted, and blood is pumped into the arteries. Diastole refers to the heart when it is relaxed and blood enters the upper chambers.
During distant vision, the ciliary muscle is relaxed, the suspensory ligament is taut, the convexity of the lens is increased, and light refraction is decreased. During close vision, the ciliary muscle is contracted, the suspensory ligament is relaxed, lens convexity is increased, and light refraction is increased.
The state when even relaxed muscles are almost always in a slightly contracted state is called muscle tone. It does not produce active movement, but it keeps the muscles firm and healthy and ensures that they are ready to respond to a sudden stimulus. Muscle tone also helps to stabilize joints and to maintain posture.
