Animal Tissues Flashcards
Animal tissues are divided into;
Epithelial, connective, muscular and nervous tissues
The protective covering of the body and inner lining of the body and organs.
Epithelial tissue
First to evolve during evolution and were first formed during embryonic development.
Epithelial tissue
It can be single-layared or multi-layared and have the power to generate.
Epithelial tissue
They are held together by gap and junctions, tight junctions, zonula adheren, demosomes, or interdigitating.
Epithelial tissue
Classification of epithelial tissue
sensory, glandular, pigmented, and absorptive epithelium
Secrets chemicals
Glandular epithelium
To perceive stimuli
Sensory epithelium
Imparts colour of retina
Pigmented epithelium
For absorption
Absortive epethelium
It is developed from the mesodermal cells of the embryo.
Connective tissue
They support and bind other tissues in the body.
Connective tissue
Three components of connective tissue
Intercellular matrix, cells and fiber
It is made up of mucopolysaccharides, specifically hyaluronic acid.
Intercellular matrix
The major cells include fibroblast, adipocytes, plasma cells and mast cells.
Cells
Connective tissues that are made up of three types of fibers
Collagen, elastic and reticular fiber
Attaches organs and tissues together. Stores fat in the form of adipose tissues
Connective tissue
Prevent organs from mechanical shock
Connective tissue
Classification of connective tissue
Connective tissue proper, vascular and skeletal
Provides support and protection to the body
Connective tissue proper
Transport of materials in the body
Vascular tissue
Supports the body and gives it proper shape and form
Skeletal tissue
It develops from mesoderm of the embryo.
Muscular tissue
Classification of muscular tissue
Cardiac, smooth and skeletal muscle
