Fill In The Blanks:
1. Movement is the action taken by living organism to reduce its irritation.
2. Locomotory movement require skeletal system, Muscular system.
3. Osteoporosis is more common in female than male.
4. Skeleton provides support to the body, especially limbs. i.e. Hind Limbs and pelvic girdle.
5. Cartilages also support larynx, trachea and bronchi of respiratory system.
6. There are three types of cells associated with bones i.e. bones forming cells (osteoblast), mature bone cell (osteocyte) and bone dissolving cells (osteoclast).
7. In humans 206 bones are present which can be categorized into two groups.
8. The junction of two bones is called a joint.
9. There are two types of joints.
10. Immovable or fixed joint are those joint where bones are fixed like puzzle pieces.
11. Hinge Joints (e.g knee joint) allow movement in one plane only.
12. Ball and socket allow movement in many plans.
13. The strong connective tissue in the ligaments protects these structures and prevents them from bending twisting or tearing.
14. Skeletal muscles are attached to bones on either side of the joint by bands of tough, fibrous connective tissues called tendons.
15. The type of working of two muscles against each other called antagonism.
16. The pair of skeletal muscles which work against each other called an antagonistic pair.
17. The action of biceps and triceps muscles of arm is a good example of an antagonistic pair.
18. When the biceps muscle contracts it pulls upon the radius bone of lower arm, which bend the arm at elbow, this bending process is called flexon.
19. When triceps muscle contracts it pull on the ulna which straightens or extends the arm. The straighten process is called extension.
20. In arm the biceps is the flexor muscle and tricep is the extensor muscle.
21. A long term calcium deficiency can lead to dental weakness, osteoporosis, in childhood rickets.
21. Osteoporosis is a disorder related to the aging process.
22. Rickets is the softening and weakening of bones in children, usually because of an extreme and prolonged vitamin D deficiency.
