Types of Muscles

Ligaments vs. Tendons

• Skeletal/Voluntary- Skeletal muscle fibers occur in muscles which are attached to the skeleton. Those muscles that can be moved by our thoughts and actions.

• Smooth/Involuntary Muscle- Muscles that moves internal organs, such as the bowels, and vessels. Reflex action is made without our thought.

• Cardiac- The muscle of the heart Ex: This muscle is constantly working automatically without thought or reflex being needed. Without this cardiac functioning muscle, we die!

• Ligaments connect bones while tendons connect muscles to bones.

Muscle Anatomy

• Deltoids- a large, triangular muscle covering the joint of the shoulder, the action of which raises the arm away from the side of the body.

(any movement involving wrist rotation)
