Skeleton

Question 1

Musculoskeletal system

Answer 1

name to describe the muscular and skeletal systems working together

Question 2

Articulating bones

Answer 2

bones that meet at a joint to enable movement

Question 3

Synovial joint

Answer 3

where 2 or more articulating bones meet to enable movement

Question 4

Tendons

Answer 4

Very strong, non-elastic cords that join muscle to bone

Question 5

Bursae

Answer 5

Sac filled with liquid floating inside the joint to reduce friction between tendon and bone

Question 6

Cartilage

Answer 6

Tough but flexible tissue that acts as a buffer between the bones, preventing bones rubbing together and causing friction

Question 7

Synovial fluid

Answer 7

Clear and slippery liquid that lubricates the joint and stops the bones rubbing together

Question 8

Ligaments

Answer 8

Bands of elastic fibre that attach bone to bone, keeping joints stable by restricting movement

Question 9

Synovial membrane

Answer 9

The lining inside the joint capsule that secretes synovial fluid

Question 10

Joint capsule

Answer 10

Tissue that stops synovial fluid from escaping and encloses, supports and holds the bones together

Question 11

Extension

Answer 11

Increase in angle of bones at a joint

Question 12

Flexion

Answer 12

Decrease in the angle of bones at a joint

Question 13

Abduction

Answer 13

Movement of a bone or limb away from the midline of the body

Question 14

Adduction

Answer 14

Movement of a bone or limb towards the midline of the body

Question 15

Dorsi flexion

Answer 15

Decrease in angle at ankle joint (flexes foot upwards)

Question 16

Plantar flexion

Answer 16

Increase in angle at ankle joint (points the toes)

Question 17

Rotation

Answer 17

Circular movement around a joint / movement around an axis
