Accepted Answer

Areolar connective tissue

Question 5

Which of the following best explains the role of parathyroid hormone (PTH) in calcium homeostasis?

Accepted Answer

Question 8

Which equation best represents the relationship between force generated by a muscle and the number of motor units recruited?

Accepted Answer

$F = n 	imes f_{unit}$

Question 9

Which of the following is a structural component of the osteon in compact bone?

Question 12

Question 18

Which of the following best describes the difference between muscle origin and muscle insertion?

Accepted Answer

Origin is the immovable attachment, insertion is the movable attachment.

Question 19

Which of the following best describes the role of acetylcholinesterase in muscle contraction?

Accepted Answer

It breaks down acetylcholine, stopping the signal for muscle contraction.

Question 20

Which of the following best describes the difference between osteoarthritis and rheumatoid arthritis?
