Joints (synovial)

Question 1

what is a joint?

Answer 1

where 2 or more bones meet

Question 2

what are the 3 types of joint?

Answer 2

-Synovial
-Slightly moveable
-Fixed

Question 3

What is a fixed joint?
give some examples

Answer 3

fixed joints have no movement and they interlock or overlap
they are held together by tough fibre

e.g. cranium and ribs

Question 4

what are slightly moveable joints?
give an example

Answer 4

slighlty moveable joints allow some movement
they have tough cartilage on the ends of bones which provide shock absorbtion and stability

e.g veterbrae

Question 5

what are synovial joints?
give an example

Answer 5

synovial joints allow a ride wange of movement and are the most common joint
synovial joints let us do sport

e.g. knee hip shoulders or elbow

hinge:
hinge joints only move in one direction like a door
examples of them are the elbow and knee

Question 8

What is the function of the synovial membrane in a synovial joint?

Answer 8

the synovial membrane creates and secretes synovial fluid, a lubricant, into the joint to allow smooth movement

Question 9

what is the function of synovial fluid in a synovial joint ?

Answer 9

synovial fluid acts as a lubricant to reduce friction so movement can be smooth

Question 10

what is the function of the synovial capsule in a synovial joint?

Answer 10

a synovial capsule surrounds the synovial joint and holds bones together this keeps the joint stable so it dosent dislocate
