groups of similar cells performing a definite function
Tissues
Four major types of tissues
epithelial, connective, muscular, and
nervous
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.
Epithelial tissue
made up of one layer of cells (The number of cell layers)
Simple epithelium
made up of one layer of cells but of different
heights, thus showing a stratified appearance (The number of cell layers)
Pseudo stratified
made up of more than two layers of cells (The number of cell layers)
Stratified
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.
Squamous epithelium
Based on the shape of the cell
Source: lining of kidney tubules
DESCRIPTION: Dice shape, square-like shape with large and spherical nuclei.
Cuboidal epithelium
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.
Columnar epithelium
Based on function
specialized for reception of stimulus
Sensory epithelium
Based on function
specialized for secretion
Glandular epithelium
Based on function
specialized for production of germ cells
Germinal epithelium
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
Loose Connective Tissue & Dense Connective Tissue
Types of CONNECTIVE TISSUE
fibers in the matrix are loosely arranged
