e. The trachea is lined by pseudostratified squamous epithelium. Epithelium lines body cavities and surfaces. Pseudostratified squamous epithelium is "pseudostratified" because it is only one cell layer thick, yet it appears to be stratified. In reality, every cell touches the basement membrane.

e. the lining of the bladder is transitional epithelium. Epithelium lines body cavities and surfaces. There are domed shapes cells on the apical surface.

what type of gland secretes its product directly into the bloodstream a. endocrine gland b. multicellular gland c. exocrine gland d. all of the above e. none of the above

a. an endocrine gland secretes its product directly into the bloodstream without a duct or tube. An exocrine gland secretes its product through a duct or tube.

what do you call a tissue composed of a conglomeration of cells which are tightly packed together, yet which does not have a free surface? an example of such a tissue would be the parenchyma of the adrenal gland a. epithelioid tissue b. mesothelium c. endothelium d. transitional e. pseudostratified

a. epithelial tissue has cells that are very tightly packed together. There is always a free surface associated with epithelial tissue. If a tissue is composed of a conglomeartion of cells in tightly packed together, but it does not have a free surface, the tissue is called epithelioid tissue. An example of epithelioid tissue is the parenchyma of the adrenal gland

What forms the brush border a. microvilli b. stereocilia c. cilia d. keratinization e. Both a and b

a. microvilli are the finger like projections seen on the surface of some cells. The appearance of microvilli form what is also called the brush border or striated border. Stereocilia ere very long microvilli. Stereocilia are seen in the epidymis and the hair cells of the ear. Cilia is the hair like surface modification seen on some epithelia. Cilia are made of microtubules. Keratinizatiion is seen in the epidermis. Cells in the stratum corneum are essentially just bags of keratin.

what type of tissue lines most ducts a. simple squamous epithelium b. simple cuboidal epithelium c. simple columnar epithelium d. stratified squamous epithelium e. transitional epithelium

b. the lining of most ducts is simple cuboidal epithelium. Epithelium lines body cavities and surfaces. Simple cuboidal epithelium is ,,simple" because it is one cell thick. "cuboidal" refers to the shape of the cells

what cell type makes up the mucosa of the gallbladder a. simple squamous epithelium b. simple cuboidal epithelium c. simple columnar epithelium d. stratified squamous epithelium e. transitional epithelium

c. The mucosa of the gallbladder is made of simple columnar epithelium. The simple columnar epithelium of the gallbladder is very tall!

what type of gland secretes its product through a duct or tube a. endocrine gland b. multicellular gland c. exocrine gland d. all of the above e. none of the above

c. an endocrine gland secretes its product directly into the bloodstream, without a duct or tube. An exocrine gland secretes its product through a duct or tube.

what do you call the simple squamous epithelium that lines the blood vessels a. epitheloid tissue b. mesothelium c. endothelium d. transitional e. pseudostratified

c. epithelial tissue has cells that are very tightly packed together. There is always a free surface associated with epithelial tissue. If a tissue is composed of a conglomeration of cells in tightly packed together, but it does not have a free surface, the tissue is called epithelioid tissue. An example of epithelioid tissue is the parenchyma of the adrenal gland. Mesothelium is simple squamous epithelium that lines the abdominal cavity, the peridcardial cavity, and the thoracic cavity. Endothelium is simple squamous epithelium that lines the vascular system. Transitional epithelium is seen in the urinary tract. Transitional epithelium has dome shaped cells on the apical surface. Pseudostratified epithelium is a type of epithelium that has cells which all touch the basement membrane. Pseudostratified epithelium is only one cell layer thick. Pseudostratified epithelium appears stratified, but it is not really stratified. Thus the name. The prefix "pseudo" means false, such as pseudonym or pseudo-science.

what type of epithelium is associated with goblet cells a. simple squamous epithelium b. simple cuboidal epithelium c. simple columnar epithelium d. stratified squamous epithelium e. pseudostratified epithelium

c. goblet cells are associated with simple columnar epithelium of the gastrointestinal tract. Epithelium lines body cavities and surfaces. Simple columnar epithelium is "simple" because it is one cell thick. "columnar" cells are taller than they are wide and have an oval nucleus

what is a characteristic of the cells in the epidermis of the skin a. microvilli b. stereocilia c. cilia d. keratinization e. both a and b

d

which of the following is NOT lined by a serosa a. peritoneal cavity b. pericardial cavity c. pleural cavity d. respiratory tract e. all of the above are lined by a serosa

d . serosa lines the peritoneal cavity, pericardial cavity and pleural cavity. Mucosa lines the alimentary canal, genitourinary tract and respiratory tract

what is a gland called if the secretory portion is flask shaped a. simple gland b. compound gland c. tubular d. alveolar e. tubuloalveolar

d. a simple gland has an unbranched duct. A compound gland has a branched duct. If the secretory portion of a gland is tube shaped, it is called "tubular". If the secretory portion of a gland is flask shaped, it is called "alveolar" or "acinar". If the secretory portion of a gland is a tube shaped but at the terminus is flask shaped, it is called "tubuloalveolar".

what type of epithelial cells are as tall as they are wide a. simple b. stratified c. squamous d. cuboidal e. columnar

d. epithelium that is classified by the number of cell layers and the cell shape. Epithelium that is one cell thick is classified as simple. Epithelium that is more than one layer thick is classified as stratified. If the cells are flat, the epithelium is termed squamous. If the cells are as tall as they are wide, it is cuboidal. If the cells are taller than they are wide, the epithelium is classified as columnar.

which of the following is lined by a mucosa a. peritoneal cavity b. pericardial cavity c. pleural cavity d. alimentary canal e. all of the above are lined by a mucosa

d. serosa lines the peritoneal cavity, pericardial cavity and pleural cavity. Mucosa lines the alimentary canal, genitourinary tract and respiratory tract.
