10. CELL CYCLE AND CELL DIVISION  The growth and reproduction of all organisms depend on the division and enlargement of cells. The mechanisms of division and multiplication of cells together constitute cell reproduction.

10. CELL CYCLE AND CELL DIVISION  MITOSIS

10. CELL CYCLE AND CELL DIVISION  MEIOSIS

22. CHEMICAL CO-ORDINATION AND INTEGRATION MECHANISM OF HORMONE ACTION

22. CHEMICAL CO-ORDINATION AND INTEGRATION 9. TESTIS (MALE GONAD)

22. CHEMICAL CO-ORDINATION AND INTEGRATION 6.   THYMUS GLAND

22. CHEMICAL CO-ORDINATION AND INTEGRATION 4.   THYROID GLAND

22. CHEMICAL CO-ORDINATION AND INTEGRATION Endocrine system includes endocrine (ductless) glands and their secretions (hormones). Hormones are non-nutrient chemicals that act as intercellular messengers and are produced in trace amounts.

21. NEURAL CONTROL AND CO-ORDINATION SENSORY RECEPTION & PROCESSING (SENSE ORGANS) EAR (STATO-ACOUSTIC ORGAN)

21. NEURAL CONTROL AND CO-ORDINATION SENSORY RECEPTION & PROCESSING (SENSE ORGANS) These are the organs that detect the changes in the environment and convey the information to the CNS. It includes eye, ear, nose, tongue & skin.

21. NEURAL CONTROL AND CO-ORDINATION PERIPHERAL NEURAL SYSTEM (PNS) It includes cranial nerves and spinal nerves.

21. NEURAL CONTROL AND CO-ORDINATION HUMAN NERVOUS (NEURAL) SYSTEM It has 2 parts:

21. NEURAL CONTROL AND CO-ORDINATION GENERATION & CONDUCTION OF NERVE IMPULSES Impulse transmission is electrochemical. It has 3 steps:

21. NEURAL CONTROL AND CO-ORDINATION Neural (Nervous) system is a system that controls and coordinates the body activities, conducts and integrates the information and responds to stimuli.

20. LOCOMOTION AND MOVEMENT  JOINTS Joints are points of contact between bones, or between bones and cartilages. 3 types:

20. LOCOMOTION AND MOVEMENT  HUMAN SKELETAL SYSTEM It consists of a framework of bones (206) & few cartilages. Human skeletal system has 2 parts: axial & appendicular.

20. LOCOMOTION AND MOVEMENT  MECHANISM OF MUSCLE CONTRACTION According to sliding filament theory, contraction of a muscle fibre occurs by the sliding of thin filaments over thick filaments.

20. LOCOMOTION AND MOVEMENT  Locomotion is the voluntary movements resulting in a change in location.  All locomotion are movements but all movements are not locomotion. Both are interlinked. E.g.

19. EXCRETORY PRODUCTS & THEIR ELIMINATION HUMAN EXCRETORY SYSTEM It includes kidneys, ureters, urinary bladder & urethra.

19. EXCRETORY PRODUCTS & THEIR ELIMINATION Excretion is the elimination of metabolic wastes like ammonia, urea, uric acid etc. from the tissues.

19. EXCRETORY PRODUCTS & THEIR ELIMINATION URINE FORMATION (PHYSIOLOGY OF KIDNEY) 3 processes: Glomerular filtration, reabsorption & secretion.

19. EXCRETORY PRODUCTS & THEIR ELIMINATION REGULATION OF THE KIDNEY FUNCTION It is done by hormonal feedback mechanisms involving the hypothalamus, JGA and the heart.

19. EXCRETORY PRODUCTS & THEIR ELIMINATION DISORDERS OF EXCRETORY SYSTEM

18. BODY FLUIDS AND CIRCULATION  LYMPHATIC SYSTEM

18. BODY FLUIDS AND CIRCULATION  CARDIAC CYCLE

18. BODY FLUIDS AND CIRCULATION  3. HEART

18. BODY FLUIDS AND CIRCULATION  BLOOD VASCULAR SYSTEM It includes Heart, Blood & Blood vessels.
