Unit 3: Muscles: Chapter 6: The Muscular System:
Essential function of muscles: 1. Contraction and 2. Shortening. Both of these
are responsible for essential all body movement.
Overview of Muscle Tissues: Muscle Types:
3 Types of Muscle Tissues: 1. Skeletal Muscle, 2. Cardiac Muscle, 3. Smooth
Muscle. The 3 types are different in cell structures, body location, and how
they’re stimulated to contract.
Similarities of the 3 Muscle Types:
-Skeletal and smooth muscle cells are elongated and they’re called muscle
fibers.
-Ability for muscles to shorten or contract.
-Terminology: prefixes of myo- and mys- (“muscle”) and sacro- (“flesh”) is when
the muscle is being referred to such as muscle cells=cytoplasm=sacroplasm.
Types of Muscle Types in detail:
1. Skeletal Muscle:
-Packaged into organs called skeletal muscles that attaches to the body’s
skeleton.
-Helps to form smoother, contours of the body. They’re huge, cigar-shaped,
multinculeate cells, it is the largest one out of the fiber types.
-These muscles are only activated by reflexes.
-These muscles contract rapidly, they must rest after short periods of activity.
-This muscle can also be known as striated muscle based on it’s obvious stripes
and voluntary muscle because, it is the only muscle type that is subject to
conscious.
Key Words:
-Endomysium: is when every muscle fiber is enclosed in a connective tissue
sheath.
