$$\text{Stimulus} \rightarrow \text{Receptor} \rightarrow \text{Control Center} \rightarrow \text{Effector} \rightarrow \text{Response}$$

Question 1

Which of the following best describes the concept of emergent properties in biological systems?

Accepted Answer

New properties that appear with each step upward in the biological hierarchy, resulting from the organization and interactions of parts.

Question 2

A patient is experiencing difficulty breathing due to inflammation of the serous membrane surrounding the lungs. Which membrane is affected?

Accepted Answer

Pleura

Question 3

Which anatomical plane divides the body into right and left portions?

Accepted Answer

Sagittal plane

Question 4

During a homeostatic response to increased body temperature, which of the following best describes the sequence of events?

Accepted Answer

Stimulus activates the receptor, which sends information to the control center; the control center directs the effector to respond.

Question 5

Which term refers to the anatomical direction toward the front of the body?

Accepted Answer

Ventral

Question 6

A surgeon makes a cut that separates the body into superior and inferior portions. Which plane was used?

Accepted Answer

Transverse plane

Question 7

Which of the following is the correct order of the biological hierarchy from smallest to largest?

Accepted Answer

Cell → Tissue → Organ → Organ system → Organism

Question 8

Which of the following best illustrates negative feedback in homeostasis?

Accepted Answer

Sweating increases as body temperature rises, helping to cool the body.

Question 9

If a structure is described as 'distal' to another, what does this mean?

Accepted Answer

It is farther from the point of attachment of the appendage.

Question 10

Which serous membrane surrounds the abdominal organs?

Accepted Answer

Peritoneum

Question 11

A patient has a tumor located in the axillary region. Where is this tumor found?

Accepted Answer

In the armpit

Question 12

Which of the following is an example of positive feedback?

Accepted Answer

Release of oxytocin during childbirth to intensify uterine contractions

Question 13

Which term refers to the anatomical direction toward the midline of the body?

Accepted Answer

Medial

Question 14

Which organ system is primarily responsible for transporting oxygen and nutrients throughout the body?

Accepted Answer

Cardiovascular system

Question 15

A medical student is asked to identify the region located on the anterior aspect of the knee. Which term should they use?

Accepted Answer

Patellar

Question 16

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

Accepted Answer

It lubricates the surfaces of serous membranes to reduce friction between organs.

Question 17

Which of the following is the correct sequence for the components of a homeostatic mechanism?

Accepted Answer

$$	ext{Stimulus} ightarrow 	ext{Receptor} ightarrow 	ext{Control Center} ightarrow 	ext{Effector} ightarrow 	ext{Response}$$

Question 18

Which of the following best explains why the study of anatomy and physiology are interrelated?

Accepted Answer

The structure of body parts determines their function, and function influences structure.

Question 19

A patient is described as having a wound on the plantar surface. Where is the wound located?

Accepted Answer

On the sole of the foot

Question 20

Which of the following is an example of anabolism in metabolism?

Accepted Answer

Synthesizing proteins from amino acids
