Muscular System #2 Flashcards
Cardiac Muscle
Type of muscle that is self-exciting
Skeletal Muscle
Contracts in response to acetylcholine
Smooth Muscle
Stimulates each other to contract
Cardiac Muscle
The muscle that is slowed by acetylcholine
Smooth Muscle
The muscle that has the action of peristalsis
Skeletal Muscle
The muscle that is under voluntary movement
ATP
Needed for sustained or repeated muscle contractions
Creatine Phosphate
Produces rapid energy
Aerobic Respiration
Uses the body’s store of glucose
Pyruvate Acid
Converts to lactic acid with strenuous exercise
Lactic Acid
Causes muscle fatigue
Epimysium
The thin covering under the fascia that surrounds the muscle
Fascia
Separate the muscles from each other
Tendons
Connects muscles to bones
Perimysium
Divides a muscle into sections called fascicles
Endosyium
Surrounds individual muscle cells
Aponeurosis
Attaches muscles to the other muscles
Visceral Smooth Muscle
Type of muscle is found on hollow organs
Multiunit Smooth Muscle
Type of muscle found in the iris of the eye and walls of blood vessels
Peristalsis
The rhythmic contraction that pushes substances through tubes of the body
Pyruvic Acid
Supplies energy to living cells
ATP
Energy carrying molecule
Acetylcholine
Causes the skeletal muscle to contract ( muscle fibers respond to this neurotransmitter)
Acetylcholinesterase
Breaks down acetylcholine, allows muscles to relax
