Question 6

In-Text Figure Based Questions
-In "simple columnar epithelium," which word describes cell shape and which word describes the number of celllayers? (Figure 4-6)

Accepted Answer

"Columnar" describes the shape of the cells (they are tall and column-like), while "simple" refers to the tissue having a single layer of cells.

Question 7

In-Text Figure Based Questions
-Which muscle tissue consists of multinucleate cells? (Figure 4-19)

Accepted Answer

Figure 4-19 clearly shows that multinucleate cells are present in skeletal muscle tissue. Cardiac and smooth muscle tissues both consist of uninucleate cells.

Question 11

In-Text Figure Based Questions
-Which type of loose connective tissue provides padding, cushions shock, reduces heat loss, and stores energy? Where are some places in the body this type of tissue is commonly found? (Figure 4-11)

Accepted Answer

Adipose tissue provides padding, cushions shock, reduces heat loss, and stores energy. It is commonly found deep to the skin at the sides, buttocks, and breasts. Reticular tissue is found in the spleen, lymph nodes, and bone marrow, while areolar tissue is found deep to the dermis, between muscles, and around joints.

Question 12

In-Text Figure Based Questions
-Which method of secretion destroys the cell? (Figure 4-8)

Accepted Answer

Holocrine secretion involves the destruction of the entire gland cell, as seen in Figure 4-8. Merocrine and apocrine secretions release their products without destroying the cell. Endocrine secretion involves the release of hormones into the bloodstream, and exocytosis is simply the process of releasing any substance from a cell through the cell membrane.

Question 13

In-Text Figure Based Questions
-Which is the only type of cell junction shown here that allows the diffusion of ions and molecules between cells? (Figure 4-3)

Accepted Answer

Gap junctions are the only type of cell junction shown in Figure 4-3 that allow the diffusion of ions and molecules between cells. Tight junctions seal adjacent cells together, hemidesmosomes and spot desmosomes anchor cells to the extracellular matrix, and adhesion belts help maintain the shape of tissues.

Question 14

Compare the three types of muscle tissue. List three similarities and three differences among them.

Accepted Answer

The answer of Compare the three types of muscle tissue....

Question 15

In-Text Figure Based Questions
-What is the only type of cell found in cartilage matrix? (Figure 4-16)

Accepted Answer

Figure 4-16 shows a diagram of cartilage matrix and identifies chondrocytes as the only type of cell present.

Question 16

In-Text Figure Based Questions
-Which formed element of the blood contains a nucleus? (Figure 4-14)

Accepted Answer

White blood cells, also known as leukocytes, contain a nucleus.

Question 17

Explain why sunburned skin peels rather than being shed as a powder.

Accepted Answer

The answer of Explain why sunburned skin peels rather than...

Question 18

Why is cardiac muscle tissue that has been damaged by injury or disease incapable of regeneration?

Accepted Answer

The answer of Why is cardiac muscle tissue that has...

Question 19

Harriet had liposuction several years ago, but has since gained back all the weight lost through the procedure. She does not understand her weight gain because adipocytes are incapable of dividing. Provide a plausible explanation.

Accepted Answer

The answer of Harriet had liposuction several years ago, but...
