1. wrist bones

2. bones of the fingers and toes

3. tibia

4. bones located in the ankle

5. color bone

6. a point at which two bones meet

7. a lubricating fluid which helps to avoid friction

8. a skeleton which consists of the shoulder girdle, the pelvic girdle, the forelimbs and the hind-limbs

9. a long bone in the upper arm

10. bones consisting of ileum, the ischium, and the pubis

 

35. Use mini-dictionary to help you:

38. Watch again and answer the following questions (from 5:46 minute):

 

1) What movements does a hinge joint allow?

2) What are the examples of hinge joints?

3) What are the examples of gliding joints, ball and socket joints?

4) What is pivot-joint? Give the examples of this type of joints.

5) Why a synovial joint is called so?

 

 

39. Watch again and decide if the sentences below are true (T) or false (F):

 

a. Our skeletal system has various joints that connect our bones to each other.

b. The appendicular skeleton is attached to the axial skeleton.

c. The lower leg contains three bones.

d. Patella has developed from the fibrous bands.

e. The scapula is flat and triangular in form.

f. Hip bones are composed of two sections.

g. Moveable joints allow less movements then immovable and partially movable joints.

h. Lubricating fluid is called a lymph.
