Definition. a tissue is a group of similar cells with intercellular material that together perform a specific function. Four basic tissues and germ layer derivative 1. Epithelialtissue: ectoderm, endoderm, mesoderm 2. Connective tissue: mesoderm 3. Muscle tissue: mesoderm. Epithelialtissue can have what's called microvilli. Basically it's finger-like projections off the outside of the cell. What this does is it actually increases the surface area. Instead of just having this straight length of cell membrane, we actually have all of this. This allows us to more efficiently absorb nutrients through the cell.
Epithelial tissue (textus epithelialis) covers the surface of the body and lining the mucous membranes, separating the body from the external environment (the cover epithelium). ... Microvilli cells prevail in the epithelium of the intestinal mucosa and gallbladder. The pseudo-layered (multi-row) epithelium is formed mainly by cells with an. A tissue is a group of cells, in close proximity, organized to perform one or more specific functions. There are four basic tissue types defined by their morphology and function: epithelialtissue, connective tissue, muscle tissue, and nervous tissue. Epithelialtissue creates protective boundaries and is involved in the diffusion of ions and. The free surface of epithelial tissue forms from the free or apical surfaces of epithelial cells. Apical surfaces of cells do not attach to other cells. Free surfaces can contain microvilli or cilia. Microvilli are cell surface modifications which increase surface area of a cell without significantly increasing the size of the cell.Microvilli are often seen in organs where the epithelium plays.
