acetylcholine is broken down by enzyme acetylcholesterase, when it's supply is no longer renewed, a calcium pump removes calcium ions from the muscle fiber and returns them to the cisternae of the sarcoplasmic reticulum. Tropomyosin then blocks the linkage site and actin slides back to it's resting place.
What else can I help you with?
What must relax in order for urination to occur?
The external urethral sphincter, a muscle that surrounds the urethra, must relax to allow the flow of urine out of the bladder and through the urethra. Relaxation of this muscle is controlled by the autonomic nervous system.
How long do I need to go without eating in order to lose muscle?
Muscle loss can start to occur after about 3-4 days of not eating, as the body begins to break down muscle tissue for energy.
What has to happen in order for the relection of the occur?
light has to hit the object then the miror then go into your eye
What controls your smooth muscle?
Smooth muscle is controlled by the autonomic nervous system, which includes both sympathetic and parasympathetic divisions. The sympathetic nervous system typically causes smooth muscle contraction, while the parasympathetic nervous system usually promotes relaxation of smooth muscle. Additionally, hormones and local factors can also influence the contraction and relaxation of smooth muscle.
What is the description of complex tics?
Complex tics consist of a repeated pattern of movements that can involve several muscle groups and usually occur in the same order.
What must happen to pollen grains in order for pollination to occur?
True pollen comes from artichokes in which farts come from natural gas.
What is the function of smooth muscle in the bronchioles?
Smooth muscle in the bronchioles helps to regulate and control the diameter of the airways. Contraction of this muscle narrows the bronchioles, while relaxation widens them, allowing for control of air flow in and out of the lungs.
What must the muscle cells be provided with in order for the muscle fatigue to end?
In order for the muscle fatigue to end the muscle cells must be provided with oxygen to 'burn' the lactic acid.
In order for the muscle fatigue to end the muscle cells must be provided with?
In order for the muscle fatigue to end the muscle cells must be provided with oxygen to 'burn' the lactic acid.
When a muscle is at rest the active sites on the actin are blocked by?
When a muscle is at rest, the active sites on the actin are blocked by tropomyosin. Tropomyosin prevents myosin binding to actin, which helps to keep the muscle relaxed. In order for muscle contraction to occur, tropomyosin must be moved out of the way to expose the active sites on actin.
In order for the muscle fatigue to end the muscle cells must be provided with what?
In order for the muscle fatigue to end the muscle cells must be provided with oxygen to 'burn' the lactic acid.
Muscle that contracts in order to cause a miotic effect?
circular muscle
