Question 1

A patient is stabbed in the right side, 2nd medial to his anterior superior iliac spine. Which organ is most likely to be injured based on the anatomical location?

Accepted Answer

The appendix

Question 2

Which membrane layer directly lines the organ pointed to by the arrow in Figure 1?

Accepted Answer

Visceral peritoneum

Question 3

Which of the following is an example of a positive feedback mechanism in the human body?

Accepted Answer

As the head of the fetus pushes against the mother’s cervix, the uterus contracts, causing the head to be forced in further, which leads to more uterine contractions.

Question 4

Which of the following correctly lists the major structural levels of the body from least complex to most complex?

Accepted Answer

Atom, molecule, cell, tissue, organ, organ system, organism

Question 5

Which of the following would be an example of something an anatomist would investigate?

Accepted Answer

The developmental changes of mesenchymal tissue from an embryo, to a fetus, to a neonate

Question 6

Which of the following directional term statements is/are correct?

Accepted Answer

The femoral region is proximal to the crural region

Question 7

Which anatomical view is shown in Figure 2?

Accepted Answer

Posterior

Question 8

To properly see an image, a photon of light must pass through your cornea, be appropriately refracted by your lens, and activate either a rod or cone cell on your retina. In response to the arrival of numerous photons (bright light) on the retina, a reflex is generated by the Superior Colliculi of the Midbrain that causes the muscles of your iris to contract and decrease your pupil size. Which of the following statements correctly identifies the components of the feedback loop?

Accepted Answer

Receptor = Retina; Control Center = Superior Colliculi; Effector = Iris

Question 9

Which of the following statements best demonstrates the relationship between anatomy and physiology?

Accepted Answer

The function of the small intestine is to absorb nutrients. Nutrient absorption happens most rapidly when the surface area of the epithelium is increased. Therefore, the small intestine contains numerous microvilli.

Question 10

Which of the following is in the thoracic cavity?

Accepted Answer

The lungs

Question 11

Which of the following characteristics correctly describes epithelial tissue that contains exocrine glands?

Accepted Answer

Contains ducts for the release of its substances

Question 12

You are looking at a tissue that contains very little extracellular matrix, a large density of nucleated cells, and is found lining a body cavity. Identify this tissue.

Accepted Answer

Simple squamous epithelium

Question 13

Which of the following features is most characteristic of connective tissue?

Accepted Answer

Protein fibers

Question 14

Which type of epithelial tissue would be least protective?

Accepted Answer

Simple squamous

Question 15

Identify the outer covering at the end of the arrow in Figure 3 (labeled '15').

Accepted Answer

Periosteum

Question 16

Which of the following tissues has a free-flowing ground substance that is primarily made of water?

Accepted Answer

Blood

Question 17

Using Figure 4, identify the type of epithelium at the end of the arrow and a location where you would find that epithelium.

Accepted Answer

Simple squamous; alveoli

Question 18

A researcher is studying the effect of surface area on nutrient absorption in the small intestine. If the surface area is doubled, and the rate of absorption is directly proportional to the surface area, which equation best describes the relationship?

Accepted Answer

$$R = k 	imes A$$

Question 19

If a tissue sample contains cells with multiple layers and the apical surface is flat, which type of epithelium is present?

Accepted Answer

Stratified squamous epithelium
