Introduction to Animal Tissue

  • It is a group of connected cells with similar function within an organism.

  • These tissues vary in their structure, function, and origin.

  • Including the human body there are four basic types of tissue in the body of all animals.

Types of Animal Tissue

Types of animal tissue

Types of Animal Tissue

Blood

  • It is a fluid connective tissue.

  • Plasma is the fluid part of the blood.

  • It defends the body action against infection, repairs body tissues, transports hormones, and controls the pH of the body.

  • The arteries present in the blood carry oxygen and nutrients to all the body’s cell.

Bone Tissue

  • It is also known as osseous tissue and is a hard tissue.

  • It is a type of dense connective tissue.

  • It helps in giving rigidity to the bone.

  • It is made up of different types of bone cells.

Epithelial Tissue

  • It forms the protective covering and inner lining of the body and organs.

  • These can be single-layered or multi-layered.

  • These tissues can regenerate.

  • The plasma membrane is specialized into flagella, cilia, and microvilli.

Sensory Epithelium

To perceive stimuli.

Glandular Epithelium

It secretes chemicals.

Pigmented Epithelium

It imparts colour to retina.

Absorptive Epithelium

It is used for absorption.

Cartilage Tissue

  • It is a firm tissue but is softer and much more flexible than bone.

  • It is one of the main supporting tissues in animals.

  • During development, bone substitutes cartilage by endochondral ossification.

Adipose Tissue

  • It is present in mammals and some non-mammal animal species.

  • It functions as the major storage site for lipids.

  • The adipose tissue is formed by the cells known as adipocytes.

  • The second larger storage of lipids is the liver besides adipose tissue.

Nervous Tissue

  • It makes up the peripheral and the central nervous system.

  • It also could initiate and transmit the nerve impulse.

Main Components:

  • Neurons: Structural and functional unit of nervous system.

  • Neuroglia: Special cell sins the brain that provide support to the neurons and fiber.

  • Neurosecretory Cells: They are responsible for releasing chemical rom the axons directly into blood.

Muscular Tissue

It develops from the mesoderm of the embryo.

Classification

  • Cardiac: Helps in the circulation of blood.

  • Smooth: It helps in peristalsis and other involuntary functions of the body.

  • Skeletal: It provides support and help in movement.

Connective Tissue

  • It develops from develop from the mesodermal cells of the embryo.

  • They store fat in the form of adipose tissues.

  • The also protect the organs from mechanical shocks.

  • They further help in repairing tissues.

Three components:

  • Intercellular Matrix:

  • Cells: It includes fibroblasts, adipocytes, plasma cells, etc.

  • Fibres: Collagen fiber, elastic fiber, reticular fiber is the three types of fiber in Connective tissues.
