What are the three types of muscle?

Skeletal, Smooth and Cardiac

200

T or F: Skeletal muscle is uni-nucleated?

False

300

Name the structure that houses calcium ions.

Sarcoplasmic reticulum 

400

What is the A-band?

location in the sarcomere where actin and myosin interact

500

Correctly list the order of depolarization:

- The t-tubules

- The sarcoplasmic reticulum

- The cell membrane

1. The cell membrane 

2. The t-tubules

3. The sarcoplasmic reticulum

Function

100

What is the main function of skeletal muscle 

Movement/stability

200

T or F: Cardiac muscle works voluntarily

False

300

T or F: Cardiac muscle is located in other areas of the body besides the heart such as the lungs and liver

False - it is only in the heart

400

T or F: The main functions of smooth muscle are: peristalsis, uterine contractions, and pupil dilation

true

500

What is the correct order of these events?

- Calcium ion binds to troponin

- The sarcoplasmic reticulum becomes depolarized

- Acetylcholine is released into the NMJ

- ATP -> ADP + P on the active site of myosin

1. Acetylcholine is released into the NMJ

2. The sarcoplasmic reticulum becomes depolarized

3. Calcium ion binds to troponin

4. ATP -> ADP + P on the active site of myosin

Name it

100

What is the name of the type of muscle only located in the heart?

Cardiac muscle

200

T of F: the name of the think filament is actin

False - it is myosin

300

What is the name of the neurotransmitter located within the neuromuscular junction?

Acetylcholine

400

Name the structure which define the boundaries of the sarcomere.

Z-line

500

Name the myofilament which holds the protein structure that binds onto calcium ions in order to expose myosin binding sites.
