      \n
    1. Ear pinna –<\/strong> The pinna or the external ear collects the sound waves from different directions and send them to the middle ear.<\/li>\n
    2. External auditory meatus It forms a passage from the pinna to the eardrum.<\/li>\n
    3. Cochlea –<\/strong> It converts vibrations into nerve impulses and thus helps in hearing.<\/li>\n
    4. Semicircular canals –<\/strong> It responds to change in position and maintains balance.<\/li>\n
    5. Lachrymal gland –<\/strong> It secretes a watery fluid which washes the surface of eyes.<\/li>\n
    6. Eyelids –<\/strong> It blinks to clean the dust and grit from the cornea.<\/li>\n
    7. Retina –<\/strong> It is a photosensitive layer to receive the image.<\/li>\n
    8. Eye lens –<\/strong> It focuses the image on the retina.<\/li>\n
    9. Pupil –<\/strong> It regulates the amount of light that enters the eye.<\/li>\n
    10. Olfactory lobe –<\/strong> These are concerned with the sense of smell.<\/li>\n
    11. Optic lobe –<\/strong> These are concerned with vision.<\/li>\n
    12. Medulla oblongata –<\/strong> It controls involuntary functions of the body like – coughing, swallowing, breathing, heartbeat, etc.<\/li>\n<\/ol>\n

          \n
        1. Nerve impulse –<\/strong> It is an electrochemical change occurring in the membrane of a nerve fibre produced by a stimulus.<\/li>\n
        2. Axon –<\/strong> It is a fibre like process of the neuron which carries impulses away from the cell body.<\/li>\n
        3. Cyton –<\/strong> It is an oval, angular, polygonal or stellate body which contains a large central nucleus.<\/li>\n
        4. Action potential –<\/strong> A momentary change in electrical potential on the surface of a cell, or a nerve or muscle cell, that occurs when it is stimulated, resulting in the transmission of an electrical impulse.<\/li>\n
        5. Reflex action –<\/strong> It is an immediate and involuntary response to a stimulus.<\/li>\n
        6. Yellow spot –<\/strong> It is the region of best vision where more cone cells are present.<\/li>\n
        7. Blind spot –<\/strong> It is the region of no image formation because of lack of cone cells.<\/li>\n
        8. Power of accommodation –<\/strong> It is the ability of the lens to focus on far and distant objects.<\/li>\n<\/ol>\n

          1. A – Cerebrum; B – Cerebellum; C – Medulla oblongata<\/li>\n
          2. (A) Cerebrum –<\/strong> It is concerned with intelligence, memory and voluntary activities.<\/li>\n
          3. Cerebellum –<\/strong> It is concerned with body equilibrium.<\/li>\n
          4. Medulla oblongata It controls all involuntary activities like heart beat, respiration, etc.
