Accepted Answer

Homeostasis

Question 3

Which of the following scenarios best illustrates a negative feedback mechanism?

Accepted Answer

When blood glucose rises, insulin is secreted to lower it back to normal levels.

Question 4

In anatomical position, which of the following statements is correct?

Accepted Answer

The body stands upright, feet slightly apart, and palms facing forward.

Question 5

A surgeon makes a cut that divides the body into anterior and posterior parts. Which plane is this?

Accepted Answer

Frontal (coronal) plane

Question 6

Which of the following best describes the difference between the terms 'proximal' and 'distal'?

Accepted Answer

'Proximal' means closer to the origin of a body part or the point of attachment, while 'distal' means farther away.

Question 9

A patient presents with pain in the left lower quadrant (LLQ) of the abdomen. Which organ is most likely involved?

Accepted Answer

Descending colon

Question 10

Which of the following best describes the function of serous membranes?
