Chapter 4 Reading

D) within the cartilage divide and secrete new matrix

Chondroblasts ________. A) never lose their ability to divide B) are mature cartilage cells located in spaces called C) remain in compact bone even after the epiphyseal plate closes D) within the cartilage divide and secrete new matrix

A) tissue

Groups of cells that are similar in structure and perform a common or related function form a(n) ________. A) tissue B) organism C) organ system D) organ

A) provide flexibility Elastic fibers contain elastin, a rubberlike protein that allows them to stretch and recoil like rubber bands, making them very flexible.

In connective tissue, the role of elastic fibers is to __________. A) provide flexibility B) provide tensile strength C) form delicate networks around blood vessels D) retain fluid

D) absorption Absorption, the movement of substances into the body, is a role of epithelial tissue. Roles of connective tissue include binding and support, protection, insulation, and transportation of substances, via blood, within the body.

Which of the following is NOT a role of connective tissue? A) support B) insulation C) transport D) absorption

D) Epithelial tissue is innervated. Epithelial tissue is an innervated, avascular tissue that exhibits polarity. Epithelial tissue is also highly regenerative.

Which of the following is a property of epithelial tissue? A) Epithelial tissue is typically unable to regenerate. B) Epithelial tissue contains blood vessels. C) Epithelial tissue does not exhibit polarity. D) Epithelial tissue is innervated.

C) epithelial tissue Epithelial tissue is a sheet of cells that covers a body surface or lines a body cavity (epithe = laid on, covering). In addition to coverings and linings, epithelial cells can also form glands, called glandular epithelium.

Which tissue type consists of a sheet of cells that covers a body surface or lines a body cavity? A) connective tissue B) muscle tissue C) epithelial tissue D) nervous tissue

C) They have a common origin: mesenchyme. Adipose tissue, bone, and blood (like all connective tissues) are derived from mesenchyme, an embryonic tissue. Also common to all connective tissues is the presence of cells and an extracellular matrix that consists of fibers bathed in ground substance.

Why are adipose tissue, blood, and bone all considered to be connective tissues? A) They have the same types of cells. B) They all have collagen and elastic fibers in their extracellular matrix. C) They have a common origin: mesenchyme. D) They connect to each other.

C) Pseudostratified columnar

________ epithelium appears to have two or three layers of cells, but all the cells are in contact with the basement membrane. A) Transitional B) Stratified columnar C) Pseudostratified columnar D) Stratified cuboidal
