There are four main types of tissues in the body: epithelial, connective, muscular, and nervous tissue. Epithelial tissue forms protective layers and lines body cavities and organs. Connective tissue binds organs together, provides structure and support, stores fat, transports substances, and repairs tissue damage. Muscular tissue contains three types of muscle - skeletal, cardiac, and smooth muscle - that produce movement, maintain posture, and generate heat. Nervous tissue is made up of neurons and neuroglia found in the brain, spinal cord, and nerves to coordinate body functions and activities.

- 1. TISSUE ANATOMY AND PHYSIOLOGY MABM 0114 SEM 1 /YEAR 1 PN NOR AINI
- 2. LEARNING OBJECTIVE At the end of the course, the student will be able to: List the body's four major tissue types and describe their roles. State the types and functions of epithelial cells. Expalin the structures and functions of the various types of connective tissues. State how epithelial and connective tissues combine to form four types of membranes and specify the functions of each. State the three types of muscle tissue and the special structural features of each.
- 3. Introduction Tissue is a group of cells that have similar structure and that function together as a unit. There are 4 main type of tissue Epithelial tissue Connective tissue Muscular tissue Nervous tissue
- 5. Epithelial Tissue They form the covering of all body surface, line body cavities and hollow organs and are the major tissue gland. Rapid reproduction of cell. Function :- 1. Secretion 2. Absorption 3. Protection 4. Filtration
- 7. Simple Squamous Epithelium Single layer of flat cell. Lines heart, blood vessels, air sac of lung, glomerular capsule of kidney, inner surface of tympanic membrane and forms epithelial layer of serous membrane. Function: Filtration, diffusion, osmosis, and secretion in serous membrane.
- 9. Simple Cuboidal Epithelium Single layer of cube- shape cells. Found in glandular tissue and kidney tubule. Function : Secretion and absorption.
- 10. Simple Columnar Epithelium Ciliated and nonciliated Ciliated Layer of ciliated column like, contain goblet cell in some locations. Found in upper respiratory tract, uterine tube Function : Moves mucus and other substances by ciliary action.
- 12. Simple Columnar Epithelium (cont.) Nonciliated Layer of nonciliated column like cell. Found GIT, ducts of many gland. Function : secretion and absorption.
- 13. Ciliated Columnar Epithelium Consist of Cilia Function Cilia sweap the dust out .to prevent the dust go into the lung - Helps in movement of : Ovam , sperm in fallpian tube
- 14. Transitional Epithelium Appearance is variable, shape of cell from squamous to cuboidal. Location : Urinary bladder, portion of ureters and urethra. Function : Permits distension.
- 15. Connective Tissue : Structure:
- 16. Connective Tissue (cont.) Highly vascular – rich of blood supply. Except cartilage – avascular and tendons with scanty blood supply. Types of connective tissue : Loose Connective Tissue Adipose Tissue Dense Connective Tissue Elastic Connective Tissue Cartilage Bone Tissue Blood tissue and lymph.
- 17. Connective Tissue Areolar C T Adipose Fibrous
- 18. Connective Tissue : Function Connective tissue bind organs together. Form a framework and support for organs and the body as whole. Store fat. Transport substance. Protect against disease. Help repair tissue damage.
- 19. Muscular Tissue Structure : Consist of elongated cells called muscle fibers that can use ATP to generate force. Usually arrange in bundle and layers that surrounded by connective tissue. The tissue is highly cellular and well supply with blood vessel.
- 20. Type of Muscle Tissue Skeletal muscle tissue Attached to the bones of the skeleton. Cylindrical, multinucleated, striated and under voluntary control.
- 22. Type of Muscle Tissue Cardiac muscle tissue Most of the wall of the heart. Branched striated fibers, one or two nucleus. Involuntary. Function: Pump blood to all parts of the body.
- 23. Type of Muscle Tissue Smooth muscle tissue Non-striated, small, thickest in the middle and tapering at the end. Location : Hollow internal structures such as blood vessel – blood vessel, airway to the lung, the stomach, intestine, gallbladder, and urinary bladder. Involuntary. Function : Motion.
- 25. Muscular Tissue :Function Produces body movement. Maintain posture. Generate heat. Protection.
- 26. Nervous Tissue Consist of neuron (nerve cell) and neuroglia. Location: Brain, spinal cord and nerves. (Nervous system) Function : 1. Sensitivity to various types of stimuli. 2. Responsible coordinating and controlling many body activities.
- 27. Nerve cells Generate and conduct impulses. Nerve cells have 3 part :- 1. Dendrite 2. The cell body 3. One axon
