What is posterior?

Answer 5

Towards the back; for example the back-bone is posterior to the heart

Question 6

What is medial?

Answer 6

Towards the midline of the body; e.g. The big toe is on the medial side of the foot

Question 7

What is lateral?

Answer 7

Towards the side of the body; for example the little toe is on the lateral side of the foot

Question 8

What is proximal?

Answer 8

Towards the body’s mass; e.g. The shoulder is proximal to the elbow

Question 9

What is distal?

Answer 9

Away from the body’s mass; e.g. The elbow is distal to the shoulder.

Question 10

What is the function of the clavicle (collar bone)?

Answer 10

Gives greater mobility to the shoulder joint when movement is taking place, such as throwing a soft ball.

Question 11

What is the function of the scapula (shoulder blade)?

Answer 11

Allows the arm to attach to the trunk portion of the skeleton. Many muscles involved in movement attach to this bone

Question 12

What is the humerus bone?

Answer 12

The upper arm joining the shoulder to the elbow. It can move in most directions and rotate within the shoulder joint

Question 13

What is the Radius?

Answer 13

The long bone on the thumb side of the forearm providing movement with rotating the palm of the hand and elbow joint

Question 14

What is the ulna?

Answer 14

The longer bone of the forearm on the pinky side

Question 15

What are carpals, metacarpals and phalanges?

Answer 15

These are the bones that comprise of the wrist and fingers providing structure to the hand

Question 16

What is the function of the pelvic girdle?

Answer 16

Is to support the weight of the upper body. Also has the hip joint where the femur attaches

Question 17

What is the femur?

Answer 17

The femur is the thigh bone and the longest and strongest bone in the body.

Question 18

What is the patella?

Answer 18

The kneecap provides protection to the knee and allows protection to the knee and allows movement to the lower leg

Question 19

What is the tibia?

Answer 19

The shinbone. The larger bone of the lower leg

Question 20

What is the fibula?

Answer 20

The bone that lies parallel with the tibia in the lower part of the leg

Question 21

What are the tarsals, metatarsals and phalanges?

Answer 21

They comprise the bones of the foot

Question 22

What is a fibrous joint?

Answer 22

A joint where no movement is possible

Question 23

What is a cartilaginous joint?

Answer 23

A joint that permits limited movement

Question 24

What is a synovial joint?

Answer 24

A joint which allows maximum movement

Question 25

What is a ligament?

Answer 25

Well-defined, fibrous bands that connect the articulating bones

Question 26

What is a tendon?

Answer 26

Tough, in elastic cords of tissue that attach muscle to bone

Question 27

What is the function of synovial fluid?

Answer 27

Acts as a lubricant, keeping the joint well oiled and the moving surfaces apart

Question 28

What is a hyaline cartilage?

Answer 28

Has a limited blood supply but receives nourishment via the synovial fluid. This cartilage is ticker in the leg joints

Question 29

What is flexion?

Answer 29

A movement that increases the angle between the bones at the joint e.g. Straightening the leg at the knee

Question 30

What is extension?

Answer 30

A movement that increases the angle between the bones at the joint e.g. Straightening the leg at the knee

What is abduction?

Answer 31

The movement of a body part away from the midline of the body; e.g. Raising the leg or arm to the side

Question 32

What is adduction?

Answer 32

The movement of a body part towards the midline of the body e.g. Lowering the arm to the leg

Question 33

What is inversion ?

Answer 33

Rotation of the foot to make the sole of the foot face inwards

Question 34

What is eversion?

Answer 34

Rotation of the foot to make the sole of the foot face outwards

Question 35

What is rotation?

Answer 35

Moving a body part such as the head or trunk around on its long axis

Question 36

What is circumduction?

Answer 36

The circulation of a body part e.g. Making a large movement with the arm
