Explanation / Answer

1. Adduction is movement of parts of a body (limbs) towards the body's midline. (G)

2. flexion: is the movement that decreases angle between two bones like ulna and humerus at the elbow. (D)

3. supination is rotating the forearm laterally so that palm faces anteriorly (A)

4. extension is opposite of flexion and thus is movement that increases angle between two bones (F)

5. abduction is the opposite to adduction and thus is the movement of limbs away from the body's midline (B)

6. dorsiflexion is moving foot towards anterior leg. the toes are moved superior direction. (C)

7. plantar flexion is the movement that points foot down (E)

Compact bone is the hard and dense bone made up ground substance and inorganic salts. It has cylindrical structure called osteons. the osteon is made up of concentric circles or lamellae. osteocytes are also present within the osteon of the compact bone. Thus the compact bone has osteocytes, osteons and lamellae are present in the concentric circles.

trabeculae is presen in spongy bone tisue which is why it is also called trabecular bone

chondrocytes are present in neither type o bone tissue because they are present in cartilage

covered by endosteum: endosteum is the thin vascular lining the lines the interior of both types of bone tissue
