Muscular Structures and Functions Flashcards
1
Q
functions
A
- make body movement possible
- hold body erect
- move body fluids, blood through the veins
- produce body heat
- move food through the digestive system
- more than 600 muscle
- make up 40-45% of the body’s weight
- made up of fibers that are covered with fascia and are attached to bones by tendons
2
Q
muscle fibers
A
long, slender cells that make up muscles, each muscle consists of a group of fibers bound together by connective tissue
3
Q
fascia
A
a band of connective tissue that envelops, separates or binds together muscles or groups of muscles, flexible, but strong
4
Q
tendons
A
a narrow band of nonelastic, dense, fibrous connective tissue that attaches a muscle to a bone
5
Q
types of muscle
A
- skeletal
- smooth
- cardiac
6
Q
skeletal muscle
A
- attached to bones of the skeleton
- makes body motions possible
- voluntary muscles
- striated muscles - view under microscope
7
Q
smooth muscle
A
- located in walls of internal organs, blood
- move and control the flow of fluids through these structures
- involuntary, unstriated and visceral muscles; spindle shaped cells
8
Q
cardiac muscle
A
- form the muscular walls of the heart
- myocardium or cardiac muscle
- striated, involuntary muscle
