Ca 2+ in sarcoplasmic reticulum is released, exposing actin active sites, which the myosin head to bind to them. This results in the power stroke that contracts muscles. However, the Ca 2+ is still around, keeping the active sites exposed, which means myosin stays locked in. This muscle contraction is what is known as rigor mortis
An organism that kills and eats all or part of another organism is called a carnivore.
The genes an organism contains is called the organism's genotype.
When one organism benefits and the other organism is unaffected it is called commensalism.
That's called a parasite.
The outside of an organism has a surface area.
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.
The organs that can contract or relax in order to produce bodily movements are called muscles.
smooth muscles have the ability to sustain the prolong contraction with a little use of energy.this latching of energy in smooth muscles is called latch phenomena,smooth muscles have ability to reduce strength of stimulus once they have fully contracted
I'm not sure what you mean by how does it attack. It is normally contracted by getting a deep wound from a filthy object. It causes muscles to draw up tight. It often attackes the muscles in the jaw, causing you to not able move your jaw. For this reason it's also called lockjaw.
The deep muscles of the human body are generally called intrinsic muscles. The muscles that are closer to the skin are called superficial muscles.
An organism that eats another organism is called a consumer.
the arm muscles which are called reflexs. the arm muscles which are called reflexs. the arm muscles which are called reflexs.

The deep muscles of the human body are generally called intrinsic muscles. The muscles that are closer to the skin are called superficial muscles.
The muscles that require conscious control are called voluntary muscles, or skeletal muscles.
they are called antagonistic muscles.
The state of partial skeletal muscle contraction is known as tonus. Muscles of the body do not have a real state of total relaxation.
