Joints (1)

Question 1

Describe what a joint is

Answer 1

• holds bone together
• is where bones meet/articulate
• involves bone shapes and soft tissues
• Allows free movement/control of movement

Question 2

What soft tissues are associated with joints

Answer 2

• Cartilage –> Hyaline (articular) and Fibrocartilage

- have NO inorganic component

Question 3

describe what a fibrous joint is

Answer 3

has DFCT tissue
structure = ligament
has limited movement stability

Question 4

describe what a cartilaginous joint is

Answer 4

has some movement
has fibrocartilage tissue
various structures have special functions

Question 5

Describe what a synovial joint is

Answer 5

is free moving
most of the limbs are this join
the amount of direction of movement is determined by the joint structure

Question 6

what are the features of a synovial joint

Answer 6

• complex, involves many different tissues + structures
• facilitation of free movement AND control of movement
• bone ends determine the range of motion at the joint

Question 7

name what’s in a synovial joint’s structure(function)

Answer 7

• bone ends
• articular cartilage
• joint capsule
• joint cavity
• synovial membrane
• ligaments

Question 8

what does the synovial membrane line, also what does it secretes

Answer 8

it lines the surface of the joint capsule

- it secretes synovial fluid which lubricates the joint and give nutrients to the tissue

Question 9

what are the names of the synovial joint shapes

Answer 9

• plane joint
• hinge joint
• pivot joint
• condylar joint
• ellipsoid joint
• saddle joint
• ball and socket joint
