types of muscle tissue
skeletal, cardiac, smooth
skeletal muscle tissue
Voluntary muscle pulls on bones and causes body movements.
cardiac muscle tissue
specialized muscle tissue found only in the heart
smooth muscle tissue
Involuntary muscle is found in the intestines where it pushes food along the digestive
tract. Also found in arteries and veins.
Muscle makes up approximately what percentage of the body's weight?
40%-50%
Functions of muscles
movement, stability, control of body openings and passages, heat production, glycemic
control
Extensibility
the ability to be stretched or extended
Elasticity
The ability of a material to bounce back after being disturbed
Perimysium
The connective tissue that surrounds fascicles.
Epimysium
covers the entire skeletal muscle
Endomysium
Connective tissue surrounding a muscle fiber
Sarcoplasm
cytoplasm of a muscle cell
Myoglobin
An oxygen-storing, pigmented protein in muscle cells.
actin and myosin
Tropomyosin
A protein of muscle that forms a complex with troponin regulating the interaction of actin
and myosin in muscular contraction
Troponin
A protein of muscle that together with tropomyosin forms a regulatory protein complex
controlling the interaction of actin and myosin and that when combined with calcium
ions permits muscular contraction
Sacromere
Contractile unit of muscle
muscle fatigue
Inability of muscle to maintain its strength of contraction or tension; may be related to
insufficient oxygen, depletion of glycogen, and/or lactic acid buildup
Difference between red and white muscle
