Animal tissues can be categorised into four basic types based on their structure and functions: Epithelial tissue, connective tissue, muscular tissue, nervous tissue.
Blood: A red coloured fluid connective tissue consisting of plasma and blood cells (erythrocytes, leukocytes and platelets).
Cartilage: A non-porous connective tissue.
Compound epithelium: They consists of more than one layer of cells and gives a stratified appearance.
Components and types of connective tissues: The connective tissue components are the intercellular substance known as the matrix, connective tissue cells, and fibres. They comprise areolar, adipose tissue, cartilage. bone, tendons, ligaments, blood and lymph.
Connective Tissue: Serves to ‘connect’ or ‘bind’ the cells of other tissues in the body and give them rigidity and support.
Fibroblasts: Cells of the connective tissue. They form ground substance and fibres.
Histology: The branch of biology that deals with tissues’ study (histo: tissues, logos: study).
Ligament: It consists of yellow fibres and connect one bone to another bone.
Lymph: It is a type of fluid connective tissue consisting of plasma and mainly white blood cells.
Muscular tissues: They are made of muscle cells and form the major part of contractile tissue.
Nervous tissue: Nervous tissue comprises nerve cells or neurons.
Neurons: It is the structural and functional unit of a nerve cell. It comprises the cell body or cyton, dendrites, dendron and the axon.
Osteocytes: Bone cells present between the lamellae in fluid-filled spaces called lacunae.
Simple epithelium: Simple epithelium is formed of a single layer of cells is divided into the following types. They are squamous epithelium, cuboidal epithelium, columnar epithelium, ciliated epithelium and glandular epithelium.
Tendon: They are made up of white fibres and connects muscle to bones.
