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.
