Which major category of tissues has the most diverse and most numerous types of tissue?

Which major category of tissues has the most diverse and most numerous types of tissue?

Loose connective tissue can be classified as areolar, adipose, or reticular. Dense or fibrous connective tissue can be classified as regular, irregular, and elastic. The most diverse and abundant of all tissues, connective tissue holds cells together and supports the body.

What are the 4 major types of tissues?

There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue.

What major tissue group is classified by number of layers and by shapes?

Epithelial tissue

How are epithelial tissues classified and held together?

Epithelial cells are held together by tight junctions, adhering junction and desmosomes and attach to a specialized form of extracellular matrix called the basement membrane. Epithelial cells are polarized with an apical surface facing the lumen or external environment and a basal surface facing the basement membrane.

What characteristics do each type of epithelial tissue share?

All epithelial tissues have these common characteristics:

  • They form sheets of tightly bound cells or roll into tubes.
  • Epithelial cells lie on the basement membrane.
  • Epithelial cells have two different “sides”—apical and basolateral.
  • The apical side always faces out of the body (outside or into a lumen).
