Question 1

what are the 3 classes of anatomical joints?

Answer 1

synovial, cartilaginous, fibrous

Question 2

function of a synovial joint:

Answer 2

synovial joints allow for a lot of movement, but are less stable

Question 3

structure of synovial joint:

Answer 3

Synovial capsule: surround the joint and holds joint in place
Synovial membrane: lines synovial capsule, and secretes synovial fluid, to help with frictionless movement
Ligaments: stabilises the joint, helps prevent unwanted movements (intra & extra capsular ligaments)
Fibrocartilaginous menisci: helps with absorbing shock

Question 4

What are the different ligaments in a synovial joint?

Answer 4

Collagen rich capsular ligaments, they are the thickenings of outer fibrous synovial capsule.
intracapsular ligaments, with the synovial capsule

Question 5

Types of connectives tissue involved in synovial joints:

Answer 5

hyaline cartilage, covers bones at meeting points to allow for smooth movements.
synovial capsules, synovial membranes, ligaments

Question 6

Example of a synovial joint:

Answer 6

Knee

Question 7

function of cartilaginous joint:

Answer 7

allows small amount of movement, but more stable than synovial joints

Question 8

example of cartilaginous joint:

Answer 8

Pubic symphysis

Question 9

structure of cartilaginous joint:

Answer 9

Firbrocartilage connection: resists tension and compression, control the amount of movement

Question 10

connective tissue involved in cartilaginous joints:

Answer 10

Fibrocartilage

Question 11

function of fibrous joints:

Answer 11

Fibrous joints allow almost no movement, but are the most stable

Question 12

structure of fibrous joints:

Answer 12

Held together by dense fibrous connective tissue, found at places requiring protection (eg. brain)

Question 13

example of fibrous joint:

Answer 13

Cranial sutures

Question 14

connective tissue involved in fibrous joints:

Answer 14

dense fibrous connective tissue
