Different types of muscles in the body,


Cardiac muscle

In between its fibres are intermittent spaces, which contain connective tissue and many capillaries to ensure a constant supply of oxygen.

The wall of the right ventricle is thinner, as it only has to pump oxygen-depleted blood the short distance from the heart to the lungs.

Smooth muscle

Smooth muscle contracts much more slowly than skeletal and cardiac muscle.

It lines organs such as the stomach and bladder as well as our blood vessels.

Smooth muscle is involuntary muscle tissue and it controlled by the autonomic nervous system.

Skeletal muscle

They typically control movement through activation by the somatic branch of the peripheral nervous system, with a rapid speed of contraction.

Skeletal muscles are our voluntary muscles, meaning that we can control them at will.

Skeletal muscles also play a role in temperature regulation, using rapid muscle contractions (shivering) to release heat to raise body temperature

which is another example of their involuntary use.

For example, if you touch a hot stove, your skeletal muscles will respond rapidly to instant chemical and electrical impulses from the brain,

withdrawing your hand from the dangerous situation without conscious thought.

This is a result of how the subunits that makes up the muscle fibres are arranged.
