Accepted Answer

Signs

Question 3

Which of the following is an example of extrinsic regulation in homeostasis?

Accepted Answer

Question 4

Which anatomical plane divides the body into superior and inferior portions?

Accepted Answer

Transverse (horizontal) plane

Question 5

A surgeon needs to access the heart for a procedure. Which body cavity and serous membrane will be involved?

Accepted Answer

Thoracic cavity; pericardium

Question 6

Which of the following best describes the difference between gross anatomy and microscopic anatomy?

Accepted Answer

Gross anatomy studies structures visible to the naked eye, while microscopic anatomy requires magnification to study cells and tissues.

Question 7

A patient is lying face down on an examination table. What is the correct anatomical term for this position?

Accepted Answer

Prone

Question 8

Which of the following is the correct order of levels of organization in the human body, from simplest to most complex?

Accepted Answer

Chemical, cellular, tissue, organ, organ system, organism

Question 9

Which of the following best describes a negative feedback mechanism?

Accepted Answer

A process in which the response of the effector opposes the original stimulus, maintaining homeostasis.

Question 10

During childbirth, uterine contractions trigger the release of oxytocin, which intensifies the contractions. This is an example of:

Accepted Answer

Positive feedback

Question 11

Question 12

Which organ is located in the retroperitoneal space?

Accepted Answer

Kidney

Question 13

Which of the following best describes the function of serous fluid within body cavities?

Accepted Answer

Question 14

A patient has a stab wound in the right lower quadrant (RLQ) of the abdomen. Which organ is most likely to be injured?

Accepted Answer

Appendix

Question 15

Which of the following is an example of autoregulation?

Accepted Answer

A blood vessel dilates in response to decreased oxygen levels in the surrounding tissue.

Question 16

Which of the following best describes the role of the control center in a homeostatic regulatory mechanism?

Accepted Answer

It receives and processes information from the receptor and sends out commands to the effector.

Question 17

Which of the following is NOT a function of body cavities?

Accepted Answer

Producing red blood cells

Question 18

A patient is diagnosed with a disease that affects the structure of tissues but not individual cells. Which specialty of anatomy would be most relevant for studying this disease?
