Why can cell specialization be considered hazardous?
Cell specialization can be hazardous to the organism when an indispensable group of cells is damaged and looses the functionality can paralyze or destroy the organism.
A group of cells that is similar in structure and function is a tissue.
Name the four primary types of tissues.
The four primary types of tissues are nervous tissue, muscle tissue, connective tissue, and epithelium.
What is the purpose of organs?
To perform specialized function for the organism.
What is histology?
The study of tissues.
What are the 2 ways epithelial tissue occurs in the body?
1. Covering or lining epithelium (skin, internal body cavity lining) and 2. Glandular epithelium (endocrine/exocrine organs)
What are the function of epithelium?
The epithelium serves to protect, absorb, filter, excrete, secrete and sense stimuli.
What characteristics differentiate epithelial tissue from other substances?
Polarity, specialized contacts, supported by connective tissue, avascular but innervated, and regeneration.
Describe polarity of epithelial tissue and the 2 features.
Epithelium has an apical surface and basal surface.
Describe the specialized contacts between epithelial cells.
Cells of the epithelium fit together tightly and are bound by specialized junctions
