Study Notes
Muscle Types and Functions
- Skeletal muscles are responsible for maintaining posture.
- Smooth muscles are found in the walls of blood vessels and digestive organs.
- Cardiac muscles are responsible for circulating blood throughout the body.
Muscle Structure
- The connective tissue that surrounds individual muscle fibers is called endomysium.
- The thick middle part of a muscle is called the belly.
- The outermost connective tissue layer that surrounds the entire muscle is called epimysium.
Muscle Contraction and Movement
- Isometric contraction occurs when the muscle length does not shorten, but its tension increases, and no movement occurs.
- The starting point of a muscle that does not move or moves less is called the origin.
- The muscle responsible for opposing or reversing the movement of a prime mover is called an antagonist.
Facial Muscles
- There are 43 muscles in the face.
- The muscle responsible for closing the eyelids is the orbicularis oculi.
- The muscle responsible for lifting the upper lip and wing of the nose is the levator labii superioris.
- The group of muscles that includes the muscles of the scalp, eye, lip, nose, and ears is called the facial muscle group.
Other Key Facts
- There are two types of muscle fibers in the body.
- The muscular system's function is to move the body, maintain posture, and circulate blood throughout the body.
- Aponeurosis is the term used for the leaves of hard, thick, and large connective tissue associated with the adhesion of muscles.
