The ability to forcefully contract their muscle fibers

The ability of the muscles to stretch or extend

Tough fibrous connective tissue that connects muscle to bone

When the myocardium contract its forces blood into which of the following?

Wave like contraction, longitudinal and circular layer alternating

ATP- the P stands for?

A nerve impulse to the axon terminal causes and influx of this into the axon terminal

Calcium influx into the axon terminal cause what to be released from vesicles

When the channels on the sarcolemma open what rapidly goes in help generate a + charge:

After the action potential has been generated what is released into the synaptic cleft to remove Acetylcholine?

In the ATP-PC system what broken down to release energy initially?

In the ATP-PC system, what has to be broken down in order to change ADP back in ATP?

What is the end result of anaerobic glycolysis?

In anaerobic glycolysis the glucose used to fuel glycolysis yield which of the following ending anaerobic glycolysis

final step within the aerobic pathway that yields high amounts of ATP is called?

the step within the aerobic pathway that converts acetyl coenzyme A into carbon dioxide

responsible for sending nerve impulse away from the CNS

plasma membrane that wraps the muscle fibers and where the motor neuron "connects" to

The sarcoplasmic reticulum surrounds each

after an action potential, what is released from the sarcoplasmic reticulum?

ACTIN

In comparison to other cells, skeletal muscles has more of which organelle?

The epimysium blends into which part in the body

This will allow troponin to unblock and cause tropomyosin to shift allowing for cross bridge formation

an influx of what cause a change in charge in the neuromuscular junction?

The point of ________is distal and typically crosses a joint when contracted.

The orbicularis oris is a circular muscle around which of the following?

when myosin head attach to actin this is called?

When myosin head slide toward the middle of the sarcomere, this is called a

motor neuron and the muscle fiber it stimulates

overstretching the muscle or tendon is called?

overuse resulting in inflammation

A smooth, sustained contraction, with no evidence of relaxation

A small involuntary movement

muscle fibers receive an impulse before complete relaxation occurs

__________ contain(s) actin and myosin, which are crucial for muscle contraction.

Muscle contraction is a process where __________.

A. The sarcomere shortens

B. Myosin and troponin bind

C. Troponin and tropomyosin block calcium

D. Actin and myosin are at rest in the sarcomere

How many types of muscles are there?

What is the role of myosin heads in the sarcomere structure as depicted in the diagram?

What causes the muscle cell membrane gates to open during muscle contraction?

Which of the following muscle type is not striated?

What is the role of the sarcoplasmic reticulum in muscle fibers?

Identify the muscle labeled #4
