Concept explainers
To discuss:
Epithelial exfoliation and its clinical relevance.
Introduction:
Epithelial cells are a sheet of adhering cells that cover the body surfaces and cavities in the form of internal and external linings of body organs and tissues of glands. The main functions of the epithelial cells are protection, secretion, absorption, excretion, sensation, and filtration.
Stratified epithelial cells consist of 2 to 20 layers of epithelial lining, which appear in simple, cuboidal, and columnar in shape. It acts as a protective layer because it has more number of layers. It has capabilities to withstand epithelial abrasions. It undergoes self-renewing process, where the epithelial cells constantly fill the cavities of organs.

- Which type of epithelial tissue specializes in moving particles across its surface and is found in airways and lining of the oviduct? transitional stratified columnar pseudostratified ciliated columnar stratified squamousarrow_forwardLigaments connect bones together and withstand a lot of stress. What type of connective tissue should you expect ligaments to contain? areolar tissue adipose tissue dense regular connective tissue dense irregular connective tissuearrow_forward11.This type of tissue is found in many organs, including the spleen, liver, kidney, lymph nodes, tonsils, and the appendix, providing a supporting framework. dense regular connective tissue loose connective tissue reticular tissue areolar tissue dense irregular connective tissuearrow_forward
- 7. List five important characteristics of epithelial tissue.arrow_forwardThe following type of tissue is composed of a single layer of cells that looks like many: O a. Simple Cuboidal Epithelium b. Simple Squamous Epithelium O c. Simple Columnar Epithelium d. Keratinized Stratified Squamous Epithelium e. Ciliated Pseudostratified Columnar Epitheliumarrow_forwardNumerous hair-like structures extend from the cell membrane of the following type of tissue: O a. Simple Cuboidal Epithelium O b. Simple Squamous Epithelium c. Simple Columnar Epithelium O d. Keratinized Stratified Squamous Epithelium Oe. Ciliated Pseudostratfied Columnar Epitheliumarrow_forward

List five important characteristics of epithelial tissue.? short answerarrow_forward1. IDENTIFY THE EPITHELIUM. 2. IDENTIFY THE POINTED STRUCTURE. 3. WHAT GROUP OF EPITHELIUM DOES IT BELONG?arrow_forward
- Fill in the blank: 1. The or an internal passageway. 2. The rarest type of epithelium is is the side of the epithelial cell that faces the external environment and is only found in certain sweat glands. 3. The majority of connective tissue volume is matrix that consist of and 4. fibers are strong and unbranching. They resist forces in one plane of direction.arrow_forward20. Draw side views of the following tissues. Label the apical surface, basement membrane, cell membrane, and nucleus. a. simple columnar epithelium b. stratified squamous epitheliumarrow_forwardLoose Connective Tissue Please refer to the pic that's attached to answer my question Compare the structures and functions of loose connective tissue to those of epithelial tissue. What percentage of loose connective tissue is composed of cells, as opposed to the matrix? What is the function of each type of cell observed? What percentage of the matrix are fibers and what is the function of each type of fiber?arrow_forward
