What kind of muscles are triceps and biceps?

Triceps and biceps are both skeletal muscles, which are voluntary muscles that are attached to bones and are responsible for movement.

Triceps are muscles located on the back of the upper arm. They are composed of three heads: the long head, lateral head, and medial head. The long head originates from the scapula, while the lateral and medial heads originate from the humerus. The triceps insert into the olecranon process of the ulna. The triceps are responsible for extending the elbow joint.

Biceps are muscles located on the front of the upper arm. They are composed of two heads: the short head and long head. The short head originates from the coracoid process of the scapula, while the long head originates from the supraglenoid tubercle of the scapula. The biceps insert into the radius. The biceps are responsible for flexing the elbow joint and supinating the forearm.
