Joints Flashcards
What are the three types of joints?
Fibrous, cartilaginous, synovial
What is the structure and function of fibrous joints?
Strong collagen fibrous tissue, so has high tensile strength.
What are the 2 types of cartilaginous joints?
synchondroses and symphyses. Synchondroses disappears with age and symphyses stays for entire life
What is 1 example of each cartilaginous joint?
Syndrochondrosis - Epiphysial growth plate (no movement at all). Symphyses - intervertebral discs (little movement)
What are 3 examples of fibrous joints?
Cranal sutures in cranium. Periodontal ligaments in tooth. Interosseus membranes
What are synovial joints and where are they found?
Meaning ‘egg’, they’re found at most joints in the body. There are 6 types.
Example of 2 synovial joints
Elbow and Knee
What is a cartilaginous joint?
A joint between 2 rigid components made of any type of cartilage.
What 3 factors determine joint stability?
Presence of fibrous capsules, type of joint, presence of muscle
What is anastomoses?
Rejoining of blood vessels to produce an alternative route for blood flow if flexion of the body squeezed blood vessels.
How do joints receive nutrients?
They have a rich blood and nerve supply
What is proprioception and how is it relevant?
The sense of where your body parts are. Joints have the neutrons that control this
What are the 6 synovial joints?
hinge, saddle, planar, ball and socket, condyloid, pivot
Where can I find a condyloid joint? What does it allow?
Wrist. Allows side to side and left forward-backward movement but no rotation
Where can I find a planar joint?
Between tarsal bones on foot. Motion is limited but allows gliding
