Unit 2 - Tissues

groups of similar cells performing a definite function

Four major types of tissues

This tissue lines outer and inner surfaces of the body. In most types of epithelial tissue, the cells are compactly arranged and rest on a basement membrane.

made up of one layer of cells (The number of cell layers)

made up of one layer of cells but of different heights, thus showing a stratified appearance (The number of cell layers)

made up of more than two layers of cells (The number of cell layers)

Based on the shape of the cell Source: outermost layer of the skin DESCRIPTION: Thin, scaly-look like, flattened on the surface, fried-egg appearance with rounded nucleus.

Based on the shape of the cell Source: lining of kidney tubules DESCRIPTION: Dice shape, square-like shape with large and spherical nuclei.

Based on the shape of the cell Source: inner lining of the digestive tube DESCRIPTION: Taller rather than wide column in shape, long and rectangular shape with oblong nuclei or elongated nucleus contain goblet cells.

Based on function specialized for reception of stimulus

Based on function specialized for secretion

Based on function specialized for production of germ cells

This type of tissue all develop from the mesenchyme found in the embryo. The cells are loosely arranged and are supported by a solid or liquid matrix. The solid matrix may contain other cells or fibers produced by ____________________.

Types of CONNECTIVE TISSUE

Types of CONNECTIVE TISSUE fibers in the matrix are loosely arranged

Types of CONNECTIVE TISSUE fibers in the matrix are compactly arranged
