Question

1) Identify the joints and label the picture.

2) Write the functions of different joints.

3) What will happen if you don’t have joints.

4) How many bones are there in our body?

5) Name the largest bone and smallest bone in our body.

6) What are tendons?​

Answer 1

Explanation:

1) 1. Pivot joint

2. Ball and socket joint

3. Hinge joint

4. Hip joint

5. Knee joint

6. Hinge joint

2) 1. The structure allows rotational movement, as the rounded bones move around its own axis.

2.Ball-and-socket joint, also called spheroidal joint, in vertebrate anatomy, a joint in which the rounded surface of a bone moves within a depression on another bone, allowing greater freedom of movement than any other kind of joint.

3. Hinge joints function by allowing flexion and extension in one plane with small degrees of motion in other planes.

4. The hip joint is a ball and socket synovial joint, formed by an articulation between the pelvic acetabulum and the head of the femur.

5. As the knee is a synovial hinge joint, its function is to permit the flexion and extension of the lower leg relative to the thigh.

3) Joints are where two bones meet. They make the skeleton flexible. Without them, movement would be impossible.

4) Bones provide the structure for our bodies. The adult human skeleton is made up of 206 bones.

5) Femur is the largest and stapes is the smallest bone.

6) It is a fibrous connective tissue which attaches muscle to bone. It may also attach muscles to structures such as the eyeball. It also serves to move the bone or structure.
