Question

1 Define the following. a) skeleton (b) joints (c) ligaments
​

Answer 1

Answer:

a. Skeleton-The adult human skeleton is made up of 206 bones. These include the bones of the skull, spine (vertebrae), ribs, arms and legs. Bones are made of connective tissue reinforced with calcium and specialised bone cells. Most bones also contain bone marrow, where blood cells are made.

b.Joints- A joint is the part of the body where two or more bones meet to allow movement. Generally speaking, the greater the range of movement, the higher the risk of injury because the strength of the joint is reduced. The six types of freely movable joint include ball and socket, saddle, hinge, condyloid, pivot and gliding.

c. ligaments-A ligament is a fibrous connective tissue that attaches bone to bone, and usually serves to hold structures together and keep them stable.
