1.THE TISSUES

Epithelial:Epithelial tissue consists of cells that cover the internal and external surfaces of the body.It functions to protect and allow for the secretion and absorbtion of substances out of and into the body.pes of tissues : epiteal, conective,muscular,and nerou

b) Connective:Connective tissue consists of cells dispersed in a non-cellular matrix of several types.It functions to bind other tissue types and the organs together, provides support and protection, produces blood cells, and stores fat

) Muscular:Muscular tissue consists of cells called muscle fibers .Muscle fibers contain filaments of the proteins actin and myosin which allow the cell to contract to produce move

d) Nervous:Nervous tissue consists of cells called neurons and neuroglia located in the brain, spinal cord, and nerves.It functions to produce and conduct nervous impulses. These nervous impulses may be sensory (internal and external stimuli), integrative (within the brain and spinal cord), and motor (to muscles and glands)

THE TISSUES. Types of TissuesThere are four types of tissues: epithelial, connective, muscular, and nervous.a) Epithelial:Epithelial tissue consists of cells that cover the internal and external surfaces of the body.It functions to protect and allow for the secretion and absorbtion of substances out of and into the body.The shapes of the cells that make-up epithelial tissue are:1. Squamous.2. Cuboidal.3. Columnar.These cells can be arranged as a single layer called simple or into multiple layers called stratified or pseudostratified. Epithelial cells may hold cilia or microvilli and can form glands that secrete their product into ducts or directly into the blood.b) Connective:Connective tissue consists of cells dispersed in a non-cellular matrix of several types.It functions to bind other tissue types and the organs together, provides support and protection, produces blood cells, and stores fat.The types of connective tissue are:1. Loose fibrous .2. Dense fibrous - proteins matrix forms tendons and ligaments.3. Adipose - store fat. 4. Reticular5. Cartilage6. Bone - rigid, mineralized matrix.7. Blood - plasma matrix containing erythrocytes, leukocytes, and thrombocytes.TS
