Question 1

The dominant fiber type in dense connective tissue is ________.&#10;A) actin&#10;B) myosin&#10;C) elastin&#10;D) collagen

Accepted Answer

Collagen is the dominant fiber type in dense connective tissue, providing strength and durability. Actin and myosin are contractile proteins found in muscle tissue, while elastin is found in elastic connective tissue.

Question 2

What protein is involved in the formation of a blood clot?&#10;A) fibrin&#10;B) myosin&#10;C) keratin&#10;D) actin

Accepted Answer

Fibrin is the protein that is involved in the formation of a blood clot. When there is an injury, the body's natural response is to form a clot to stop the bleeding. Fibrinogen, a soluble protein found in blood plasma, is converted into fibrin, which forms a mesh-like structure that helps to seal the wound and form a clot.

Question 3

What type of connective tissue is found only in the umbilical cord?&#10;A) mucous connective tissue&#10;B) cartilage&#10;C) dense connective tissue&#10;D) loose connective tissue

Accepted Answer

The specialized connective tissue found in the umbilical cord is called mucous connective tissue. It is found exclusively in the umbilical cord and contains Wharton's jelly, which is a gel-like substance that provides support and protection for the blood vessels within the cord.

Question 4

Mesenchymal cells are most commonly found in connective tissue.&#10;A) embryonic&#10;B) areolar&#10;C) reticular&#10;D) dense irregular connective tissue

Accepted Answer

Mesenchymal cells are derived from embryonic tissue and are most commonly found in embryonic connective tissue. They are also found in adult connective tissue, such as adipose tissue and bone marrow. However, they are not specifically associated with any particular adult connective tissue, making choice B, C, and D incorrect.

Question 5

The most common cells of the lymphatic system are ________.&#10;A) eosinophils&#10;B) monocytes&#10;C) basophils&#10;D) lymphocytes

Accepted Answer

Lymphocytes are the most common cells of the lymphatic system, as they are responsible for immune responses such as recognizing and attacking foreign substances in the body. Eosinophils, monocytes, and basophils are all types of white blood cells, but they are not as prevalent in the lymphatic system as lymphocytes.

Question 6

How is hyaline cartilage different from fibrocartilage and elastic cartilage?&#10;A) it has more blood vessels&#10;B) it has more collagen fibers&#10;C) lack of fibers in the matrix&#10;D) it has more elastic fibers

Accepted Answer

Hyaline cartilage has a clear, glassy appearance due to the lack of visible fibers in its matrix, which sets it apart from fibrocartilage and elastic cartilage.

Question 7

All of the following are types of loose connective tissue EXCEPT ________.&#10;A) areolar tissue&#10;B) adipose tissue&#10;C) elastic tissue&#10;D) reticular tissue

Accepted Answer

Areolar tissue, adipose tissue, and reticular tissue are all types of loose connective tissue, while elastic tissue is a type of dense connective tissue.

Question 8

Which type of connective tissue stabilizes the positions of the vertebrae, cushions shocks, and permits expansion and contraction of organs?&#10;A) elastic tissue&#10;B) dense regular connective tissue&#10;C) dense irregular connective tissue&#10;D) areolar tissue

Accepted Answer

Elastic tissue is specialized to allow expansion and contraction of organs and structures, such as stabilizing the positions of the vertebrae and cushioning shocks, due to its high content of elastic fibers.

Question 9

The three basic types of fibers that found in connective are ________.&#10;A) tendons, ligaments, and elastic ligaments.&#10;B) cartilage, bone, and collagen&#10;C) collagen, reticular, and elastic&#10;D) loose, dense, and irregular

Accepted Answer

The three basic types of fibers found in connective tissue are collagen, reticular, and elastic. Option A lists specific types of connective tissues rather than fibers. Option B lists different types of connective tissue matrix rather than fibers. Option D lists different types of connective tissue based on density and organization rather than fibers.

Question 10

All of the following are cell types of connective tissue proper EXCEPT ________.&#10;A) erythrocytes&#10;B) adipocytes&#10;C) fibroblasts&#10;D) macrophages

Accepted Answer

Erythrocytes are red blood cells, which are part of the blood tissue and not connective tissue proper. Adipocytes, fibroblasts, and macrophages are all cell types found in connective tissue proper.
