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.
