Chapter 4 Wiley Extra Practice Questions

Electrical excitability is important to muscle fibers and neurons because it allows them to receive messages and respond to stimuli.

true

Granulation tissue is important because it forms a framework for epithelial cells to move into an open area and fill it and because it secretes an antibacterial substance.

true

1, 3, and 4

Which of the following statements is/are false? Select all that apply. 1) Mucous membranes would be found lining the digestive tract, respiratory tract and reproductive tract. 2) Serous membranes, such as the pericardium, line the thoracic cavity and cover the lungs. 3) The skin is a cutaneous membrane. 4) In synovial membranes, synovial fluid lubricates and nourishes the cartilage that covers bones at moveable joints.

2

Epithelial and connective tissues are found adjacent to each other because: a) Epithelium is avascular and needs to exchange oxygen, nutrients and waste with the blood of highly vascular connective tissue. b) Connective tissue is avascular and needs to exchange oxygen, nutrients and waste with the blood of the highly vascular epithelium. c) The two tissues are seldom adjacent to each other. d) The two are coupled by gap junctions to allow for nutrient, oxygen and waste exchange.

a) Epithelium is avascular and needs to exchange oxygen, nutrients and waste with the blood of highly vascular connective tissue.

Which of the following statements is incorrect? a) Simple squamous epithelium consists of one layer of long thin rectangular cells. b) Stratified cuboidal epithelium consists of two or more layers of cube shaped cells. c) Pseudostratified epithelium has nuclei at different heights but all cells rest on the basement membrane. d) Transitional epithelium is a type of stratified epithelium.

a) Simple squamous epithelium consists of one layer of long thin rectangular cells.

all of the above

Which of the following statement is incorrect? a) Simple squamous epithelium is found in thin layers so substances can pass through them rapidly. b) Transitional epithelium change shape to allow structures such as the urinary bladder to distend and collapse. c) Keratinized stratified squamous epithelium is adapted for absorption. d) Ciliated simple columnar epithelium moves mucus by ciliary action.

c) Keratinized stratified squamous epithelium is adapted for absorption.

Which of the following statements is incorrect? a) Mucous membranes line a cavity that opens directly to the exterior. b) Serous membranes line body cavities that do not open to the exterior. c) Cutaneous membranes cover the entire surface of the body and consist of the epidermis and dermis. d) Synovial membranes line the thoracic cavity and are double layered.

d) Synovial membranes line the thoracic cavity and are double layered.

All of the following characteristics are shared by all epithelial cells EXCEPT: a) Cells are arranged in continuous sheets. b) There is little space between plasma membranes. c) All cells have lateral surfaces which face the adjacent cells on either side. d) The surface of the cell in contact with the basement membrane is the apical surface.

d) The surface of the cell in contact with the basement membrane is the apical surface.

Which of the following statements is incorrect? a) Endocrine glands secrete products directly into the blood stream. b) Merocrine glands release products from the cell in secretory vesicles by exocytosis. c) Apocrine glands release products by pinching off the part of the cell containing them. d) Holocrine glands release products by rupturing the cell. e) Exocrine glands secrete their products directly into the blood stream through ducts.

e) Exocrine glands secrete their products directly into the blood stream through ducts.

Which of the following is mismatched? a) Adipocytes - Store large drops of triglycerides. b) Dense regular connective tissue - Contains parallel bundles of connective tissue that resist stretching in structure like tendons. c) Reticular tissue - Contains reticular fibers which make up the framework of organs like the liver. d) Elastic connective tissue - Is found in large arteries and allows stretching. e) Fibrocartilage - Contains stacks of chondrocytes and is designed to withstand pressure in structures such mucous membranes.

e) Fibrocartilage - Contains stacks of chondrocytes and is designed to withstand pressure in structures such mucous membranes.

A tissue is a group of cells that usually have a common origin in the embryo and function together to carry out specialized activities.

true

Interstitial growth of cartilage refers to growth within the cartilage while appositional growth refers to growth at the outer surface.

true

The two main groups of connective tissue are (1) embryonic connective tissue which contains mesenchyme and mucous connective tissue and (2) mature connective tissue which includes loose connective tissue, dense connective tissue cartilage, bone and liquid connective tissue.

true
