Joint Exercises 1

Question 1

What is the name for where 2 or more bones come together to create body movement or articulation?

Answer 1

The joint

Question 2

There are 3 types of joints and they are classified according to the amount of movement they permit. Which one starts with F?

Answer 2

Fibrous or immovable joints - do not move e.g. the dome of the skull is made of bony plates which must be immovable to protect the brain.

Question 3

There are 3 types of joints and they are classified according to the amount of movement they permit.Which one starts with C?

Answer 3

cartilaginous or partially movable = move a little.

Question 4

There are 3 types of joints and they are classified according to the amount of movement they permit.; Which one starts with S?

Answer 4

synovial or freely movable joints - move in many directions. Some of the main joints are hip, shoulder, elbows, knees, wrists & ankles.

Question 5

What is the name of the joints that are fixed and unable to move because thick membranous collagen fibres hold the bones together?

Answer 5

Fibrous joints (immovable joints)- AKA sutures, found in the skull bones, coronal suture joins the frontal & parietal bones.

Question 6

What is the name of the joints that have cartilage between them. Although they allow movement this is restricted.

Answer 6

cartilaginous joints (partially movable)- vertebral column & the pelvis are examples of this type of joint

Question 7

What is the name of the joint that permits the greatest range of movement?

Answer 7

Synovial joints - In between the bones are spaces covered with synovial membrane which fill with syn.fluid. This lubricates & protects the bones as they move.

Question 8

There are 6 kinds of freely moveable joints that play a part in voluntary movement which one allows a rotating or twisting motion?

Answer 8

pivot (or swivel) joints. e.g. C1 joins the axis of C2 in this way allowing the head to move from side to side.

Question 9

There are 6 kinds of freely moveable joints that play a part in voluntary movement, which ones allow the greatest freedom of movement?

Answer 9

ball & socket joints. The hips & shoulders have this type of joint in which the round ball end fits into the hollow socket of another bone.

Question 10

There are 6 kinds of freely moveable joints that play a part in voluntary movement, which joints have nearly flat surfaces where they meet which allow the bones surfaces to glide.

Answer 10

planar (or gliding joints) - they allow limited side to side & back & forth movements. e.g. between the carpals in the hands.

Question 11

There are 6 kinds of freely moveable joints that play a part in voluntary movement, which ones allow movement in one direction (flex and extend) e.g.; elbow

Answer 11

hinge joints e.g. knees as well as in the fingers and toes.

Question 12

There are 6 kinds of freely moveable joints that play a part in voluntary movement, which bones interlock like a pair of curved saddles allowing great mobility?

Answer 12

saddle joint. e.g allowing the thumb to rotate & bend back and forth.

Question 13

There are 6 kinds of freely moveable joints that play a part in voluntary movement, the dome of one bone fits into the recessed depression of another allowing limited movement?

Answer 13

ellipsoidal (or condyloid) joint. e.g. the joint in the wrist between the radius & carpals, which allows side to side & back & forth movement.
