1. where would you not expect to find epithelial tissue?

a. outer layer of the skin
b. lining of the stomach
c. within the brain
d. lining of the urinary bladder

1. which phrase best fits the function of epithelial tissue?

a. movement
b. boundary
c. sending messages
d. connecting

1. what is the difference between the apical surface of epithelial tissue and the basal surface?

a. the apical surface is not attached and is exposed; the basal surface is attached to underlying connective tissue
b. the basal surface is not attached and is exposed; the apical surface is attached to underlying connective tissue
c. the apical surface attaches to the basement membrane; the basal surface does not
d. the apical surface is avascular; the basal surface is vascular

1. which type of epithelial cell classification describes a flat cell?

a. squamous
b. simple
c. cuboidal
d. columnar
e. pseudostratified

1. which type of epithelial cell classification describes cells that appear layered, but actually are only one layer?

a. simple
b. cuboidal
c. squamous
d. pseudostratified
e. stratified

Explanation:

1. All tissues are composed of cells. Organs are made of tissues, organ - systems are made of organs, matrix is part of connective tissues, and collagen is a protein in connective tissues.
2. A group of cells with similar anatomy and physiology is a tissue. Organs are made of different tissues, organ - systems are made of organs, cell groups are a general term, and configuration is not the correct term here.
3. Epithelial tissue is not found within the brain. It is found on the outer layer of the skin, lining of the stomach, and lining of the urinary bladder.
4. One of the main functions of epithelial tissue is to act as a boundary. Movement is related to muscle tissue, sending messages is related to nervous tissue, and connecting is related to connective tissue.
5. The apical surface of epithelial tissue is not attached and is exposed, while the basal surface is attached to underlying connective tissue.
6. A flat epithelial cell is described as squamous. Simple refers to the number of layers, cuboidal cells are cube - shaped, columnar cells are tall and rectangular, and pseudostratified appears layered but isn't.
7. Pseudostratified epithelial cells appear layered but are actually only one layer. Simple refers to a single layer without the false - layered appearance, cuboidal cells are cube - shaped, and squamous cells are flat.

Answer:

1. b. Cells
2. a. Tissue
3. c. Within the brain
4. b. Boundary
5. a. The apical surface is not attached and is exposed; the basal surface is attached to underlying connective tissue
6. a. Squamous
7. d. Pseudostratified
