Types and Characteristics of Muscles
Visceral Muscles
They are also known as smooth or involuntary muscles.
They cannot be consciously controlled.
Cardiac Muscles
They are a special type of involuntary muscles, not under conscious control.
They form the walls of the heart.
Skeletal Muscles
They are also known as voluntary muscles.
They can be consciously controlled.
Muscle Action and Control
Agonist muscles initiate movement by contracting, while antagonist muscles relax to allow motion. For example, in a bicep curl, the biceps act as the agonist, and the triceps function as the antagonist.

The muscle shortens as it contracts.
For example, during the upward phase of the bicep curl, the biceps shorten as
they contract.
When the muscle contracts, the insertion moves towards the origin.
The belly is the fleshy part of the muscle between the origin and the insertion. This is where the muscle contraction takes place.
The insertion is where the muscle joins the moving bone. For example, the biceps is attached to the radius at the insertion in the elbow.
The origin is where the muscle joins the fixed bone. For example, the biceps is attached to the scapula at its origin in the shoulder.
