$$\text{Response} = -\text{Stimulus}$$

Question 1

Which of the following best describes the principle of 'complementarity' in anatomy and physiology?

Accepted Answer

The structure of a body part is directly related to its function; changes in structure can alter function.

Question 2

Which of the following is an example of negative feedback in the human body?

Accepted Answer

Regulation of blood glucose levels by insulin and glucagon.

Question 3

Which anatomical plane divides the body into anterior and posterior sections?

Accepted Answer

Frontal (coronal) plane

Question 4

If a patient is experiencing pain in the right lower quadrant (RLQ) of the abdomen, which organ is most likely involved?

Accepted Answer

Appendix

Question 5

Which of the following best describes positive feedback?

Accepted Answer

A process that amplifies the initial stimulus, leading to an enhanced response.

Question 6

Which membrane directly covers the organs within the ventral body cavity?

Accepted Answer

Visceral membrane

Question 7

Which of the following is NOT one of the nine abdominopelvic regions?

Accepted Answer

Inferior thoracic region

Question 8

Which directional term describes the relationship of the heart to the lungs?

Accepted Answer

Medial

Question 9

Which of the following is a component of a feedback mechanism responsible for detecting changes in the environment?

Accepted Answer

Receptor

Question 10

Which of the following best describes the transverse plane?

Accepted Answer

Divides the body into superior and inferior portions.

Question 11

Which of the following equations best represents the concept of homeostasis in feedback mechanisms?

Accepted Answer

$$	ext{Response} = -	ext{Stimulus}$$

Question 12

Which of the following is a subdivision of the dorsal body cavity?

Accepted Answer

Cranial cavity

Question 13

A patient has a stab wound that penetrates the parietal pericardium. Which structure is directly affected?

Accepted Answer

The membrane lining the pericardial cavity wall

Question 14

Which of the following is the correct order of components in a feedback mechanism?

Accepted Answer

Receptor → Control center → Effector

Question 15

Which of the following is a real-life example of positive feedback?

Accepted Answer

Release of oxytocin during labor to intensify uterine contractions

Question 16

Which anatomical term describes the position of the nose relative to the ears?

Accepted Answer

Medial

Question 17

Which of the following best describes the sagittal plane?

Accepted Answer

Divides the body into left and right portions.

Question 18

Which of the following is NOT a subdivision of the ventral body cavity?

Accepted Answer

Vertebral cavity

Question 19

Which of the following is the correct formula for calculating the change in a physiological variable during feedback?

Accepted Answer

$$\Delta X = X_{final} - X_{initial}$$

Question 20

Which of the following regions is located directly inferior to the umbilical region?

Accepted Answer

Hypogastric (pubic) region
