Synovial joints Skeletal Module 2

Question 1

what types of synovial joints exist?

Answer 1

• 6 synovial joints exist which are pivot, hinge, saddle, plane, condyloid, and ball-and-socket joints

Question 2

what is a ligament

Answer 2

fibrous bands connecting bone to bone. Maintains stability in joint by restraining excessive movement. Controls degree and direction of movement

Question 3

what is a tendon

Answer 3

inelastic cords of tissue attaching muscle to bone. Extends across the joint which strengthens the joint and assists ligaments to hold joint closed

Question 4

what is synovial fluid

Answer 4

acts as a lubricant by keeping the joint well-oiled and the bones separated.

Fills a cushion between the two bones forming the joint.

Provides nutrition for cartilage and removes waste.
‘Pumps’ fluid into joint space when articular cartilage is under pressure during movement.
Fluid is more viscous in colder weather (cause of joint stiffness)

Question 5

what is hyaline cartilage

Answer 5

smooth cartilage covering articulating surface of bones allowing free movement over each other.
