Question	Answer
Cardiac muscle has what?	intercalated discs.
Skeletal muscle is what?	striated.
Smooth looks just like what? BUT...	cardiac muscle but doesn't have intercalated discs.
Smallest to largest units of a muscle...	sarcomere, myofibril, muscle fiber, muscle fasicle, and THE muscle.
What are the three layers of a muscle?	epimysium, perimysium, & endomysium.
What does epimysium surround?	THE muscle.
What does perimysium surround?	the muscle fasicle.
What does endomysium surriound?	the muscle fiber.
The sarcoplasm is basically what?	the cytoplasm for the muscle.
What is the sarcolemma basically?	the cell membrane. surrounds the muscle fiber.
What is the sarcoplasmic reticulum?	a pouch filled with calcium.
What are the T tubules?	where the electronic signal travels through.
What is the triad?	formed by an T tubule and two terminal cisternae.
Thick filaments contain what?	myosin.
Thin filaments contain what?	actin.
F-actin and G-actin are?	the active sites.
Nebulin is what?	holds F-actin together.
Contraction duration depends on what three things?	duration of neural stimulus, number of free calcium ions in sarcoplasm, and availability of ATP.
What are the three twitch periods?	latent, contraction phase, & relaxation phase.
Muscle cells do not do what?	increase in number but they do increase in diameter or size.
Glycolysis is primarily for what?	peak muscle activity.
Creatine is what?	storage for excess ATP.
Cori cycle is what?	lactic acid removal and recycling through the liver. Converts into pyruvate to use as energy.
EPOC=	out of breath & repay of oxygen debt.
EPOC stands for what?	excess post-exercise oxygen consumption.
What are the functions of skeletal muscle?	produce skeletal movement, maintain posture and body position, support soft tissues, guard entrances and exits, maintain body temperature, & store nutrient reserves.
The collagen fibers of the epimysium, perimysium, and endomysium come together to form what?	bundles known as tendons or broad sheets called aponeuroses.
What is the neuromuscular junction?	is the synapse between a motor neuron and a muscle cell. This connection enables communication between the nervous system and a skeletal muscle fiber.
Muscle fatigue is in result from?	muscle's reduced ability to contract due to low pH, low ATP levels, or other problems.
What is oxygen debt?	is the amount of oxygen required to restore normal, pre-exertion conditions in muscle tissue.
What are the three types of skeletal muscle fibers?	fast fibers, slow fibers, intermediate fibers.
The connective tissue coverings of a skeletal muscle, listed from superficial to deep, are	epimysium, perimysium, and endomysium.
The command to contract is distributed deep into a muscle fiber by the	transverse tubules.
The detachment of the myosin cross-bridges is directly triggered by	the hydrolysis of ATP.
A muscle producing near-peak tension during rapid cycles of contraction and relaxation is said to be in	incomplete tetanus.
The type of contraction in which the tension rises, but the load does not move, is	an isometric contraction.
An action potential can travel quickly from one cardiac muscle cell to another because of the presence of	gap junctions and intercalated discs.
Lise the three types of muscle tissue in the body.	smooth, cardiac, and skeletal.

The ________ contains vesicles filled with acetylcholine.	synaptic terminal.
What structural feature of a skeletal muscle fiber is responsible for conducting action potentials into the inferior of the cell?	transverse tubules.
What five interlocking steps are involved in the contraction process?	exposure of active sties; attachment of cross-bridges; pivoting of myosin heads; detachment of cross-bridges; and activation of myosin heads.
What two factors affect the amount of tension produced when a skeletal muscle contracts?	both frequency of motor unit stimulation and the number of motor units involved affect the amount of tension produced when a skeletal muscle contacts.
What forms of energy reserves do resting skeletal muscle fibers contain?	resting skeletal muscle fibers contain ATP, creatine phosphate, and glycogen.
What two mechanisms are used to generate ATP from glucose in muscle cells?	aerobic metabolism and glycolysis generate ATP from glucose in muscle cells.
What is the calcium-binding protein in smooth muscle tissue?	calmodulin.

Areas of the body where you would not expect to find slow fibers include the	eye and hand.
