  1. 1. SABARIGIRI COLLEGE OF EDUCATION ANCHAL Presented by Ajeesh Kumar.N. Natural Science Reg. No. 13379001
  2. 2. ANIMAL TISSUES The human body is composed of billions of cells to perform various functions. In multicellular animals, a group of similar cells along with intracellular sub an organisation called tissues. Tissues are different and are broudly classified in to four types 1. Epithelial tissue 2. connective tissue 3. Muscular tissue 4. Neural Tissue.
  3. 3. EPITHELIAL TISSUE we commonly ruler to an epithelial tissue epitheliam. This tissue has a free surgace, which faces either a body fluid or the outside environment. and thus provides a covering or a lining for some part of the body. They are two types.
  4. 4. SIMPLE EPITHELIUM Simple epithelium is composed of a single layer of cells and function as a living for body cavities, ducts and tubes. Simple epithelium is divided into 3 types:- Squamom epithelium, Cuboidal epithelium, Columnar epithelium
  5. 5. COMPOUND EPITHELIUM It is made up of more than one layer of cells and thus has a limited role in secretion and absorption. their main function is to provide protection against chemical and mechanical stresses.
  6. 6. CONNECTIVE TISSUE They are named connective tissues, because of their special function of linking and supporting other tissues or organs of the body.
  7. 7. Connective tissues are classified in to three types. they are: 1. Loose connective tissue 2. Dense connective tissue 3. Specialised connective tissue
  8. 8. LOOSE CONNECTIVE TISSUE It has cells and fibers loosely arranged in a semi-fluid ground substances. Eg: Areolar tissue
  9. 9. DENSE CONNECTIVE TISSUE Fibers and fibroblasts are compactly packed in this sense connective tissue. Orientation of fibers show a regular or irregular pattern and are called dense regular and are called dense regular and dense irregular tissues.
  10. 10. SPECILISED CONNECTIVE TISSUE This tissue is present in the skin, cartilage, bones and blood
  11. 11. Bones: Have a hard and non- pliable grand substance rich in calcium salts and collagen fibers which give bone its strength. Cartilage: is solid and pliable and resist compression. Blood: is fluid connective tissue containing plasma, red blood cells (RBC), white blood cells (WBC) and platelets.
  12. 12. MUSCLE TISSUE It is made up of many long cylindrical fibers arranged in parallel arrays. Muscles are of three types, they are Skeletal Muscle, Smooth Muscle, Cardiac muscle.
  13. 13. Skeletal Muscle: tissue is closely attached to skeletal bones Smooth Muscle: Fiber taper at both ends and do not show striations. Cardiac Muscle tissue: is a contractile tissue present only in the heart.
  14. 14. NEURAL TISSUE Neural tissue exerts the greatest control over the body’s responsiveness to changing conditions. Neurons, the unit of neural system are excitable cells.
