How the muscle of the heart different from other muscle of the heart?
The heart muscle is different from smooth and skeletal muscles because it does not require a nerve to cause it to contract. The heart has it's own built in conduction system that cause's the automatic contraction and relaxation that is required for circulation. Smooth and Skeletal muscle whether it uses voluntary or involuntary muscle contraction all have innervation to cause the contraction. Sara, RN
How different kinds of muscles work effectively and efficiently?
Muscles are supplied by different nerves and they are placed at different parts of the body. But all the muscles are controlled by brain only. It regulates the movement of all muscles. It means contraction of muscles are relaxation of reciprocal muscles in controlled manner.
What is reciprocal contraction and relaxation of muscle?
Reciprocal innervation occurs when the prime mover contracts, such as the triceps in an arm extension and its antagonist -- the biceps -- relaxes. This allows the movement, say of a punch, to be ballistic rather than positional or gradual. The purpose of the antagonist is to stop the extension of the joint to avoid injury or to achieve a particular joint angle for a task, such as reaching for something.
The alternating expansion and contraction of artery walls caused by the contraction and relaxation of the ventricles?
This process is known as the pulse and is the result of the heart pumping blood into the arteries. As the heart contracts (systole), blood is pushed into the arteries causing them to expand. When the heart relaxes (diastole), the arteries recoil back to their original shape, creating a pulse that can be felt in different parts of the body.
What is an example to illustrate anatomy vs physiology?
A good example to illustrate the relationship between anatomy and physiology is the relationship between how a skeletal muscle is structured (anatomy) and how it works (physiology) to produce a muscle contraction. Skeletal muscles are organized into units called sarcomeres which are overlapping chains of two different proteins, actin and myosin. That in a nutshell is the microscopic anatomy of skeletal muscle. Physiologically how it works is that the myosin heads latch onto the actin chain pulling it into the center of the sarcomere shortening it which causes the contraction.
What is a sentence that uses the word interaction?
The interaction between male and female children is different to when they are adults.
What is the contraction of may be?
There is no contraction for may be. There is a word maybe, but that is not a contraction. "May be" and "Maybe" are different, and not directly related to each other. "Maybe" is an adverb. "May" acts as a modal verb for the verb be when "may be" is used.
Contains the ciliary muscle of the eye?
The ciliary muscle is located within the eye and is responsible for controlling the shape of the lens, which is crucial for focusing on objects at different distances. Contraction and relaxation of the ciliary muscle affect the thickness of the lens, allowing for accommodation of near and far vision.
What is the contraction for we had?
The contraction of "we had" (pronoun and past tense verb) is we'd (weed).It is also the contraction for "we would."Examples:We'd returned late from the party. (we had)We'd like a different look for our kitchen. (we would)
What are some calming exerciseS?
There are many different calming exercises a person can do. Most popular exercises are breathing practice, muscle relaxation and mind relaxation.
What is the relaxation modulus of plastics or polymers?
It differs between different polymers. Relaxation Modulus is the time dependent change in stress while maintaining a constant strain.
which statement best describes why the neuron and muscle cell are different?
muscle cells and nerve cells is that muscle cells are responsible for the contraction and relaxation of muscles whereas nerve cells are responsible for the coordination of the functions of the body through the transmission of nerve impulses between the body and the central nervous system.
