Joints

Question 1

What are joints?

Answer 1

The site where two skeletal components/elements come together

Question 2

What are the two main types of joints?

Answer 2

Synovial joints and solid joints

Question 3

What is a synovial joint

Answer 3

A type of joint that is separated by an articular cavity

Question 4

What is a solid joint

Answer 4

A type of joint that is connected with a connective tissue

Question 5

What are the characteristics of synovial joints

Answer 5

1. Has a layer of cartilage (hyaline cartilage)
2. Has a joint capsule consisting of synovial membrane and fibrous membrane
3. Usually has other components as well such as, articular disks, fat pads, and tendons

Question 6

What are synovial membranes

Answer 6

Synovial membrane is a connective tissue that lines the inner articular cavity

Question 7

Can synovial membranes form outside of joints? What is it for?

Answer 7

Yes, outside of joints, synovial membranes are known as tendon sheath or tendon bursae in which it intervenes between structures reducing friction

Question 8

What are fibrous membranes?

Answer 8

Fibrous membranes surrounds and stabilizes the articular cavity and is formed by dense connective tissue

Question 9

What are the type of synovial joints?

Answer 9

1. Plane joints or gliding joints
2. Hinge joints
3. Pivot joints
4. Bicondylar joints
5. Condylar joints
6. Saddle joints
7. Ball and socket joints

Question 10

What are the function of each joints

Answer 10

1. Plane joints provides gliding movement
2. Hinge joints provide movement in one axis
3. Pivot joints enable rotational movement
4. Bicondylar joints allows movement mostly in one axis while movement on the other axis is limited
5. Condylar joints allows movement in two axis at right angles
6. Saddle joints allows movement in two axis at right angles and have a saddle shape
7. Ball and socket joints allows movement ion multiple axis

Question 11

What are solid joints

Answer 11

Solid joints are a type of joint that are connected by a connective tissue, mainly fibrous connective tissue or cartilages

Question 12

What are the two type of solid joints

Answer 12

1. Fibrous joints
2. Cartilages joints

Question 13

What are the type of fibrous joints?

Answer 13

1. Sutures (In the skull, connects the skull with fibrous connective tissue also known as sutural ligament)
2. Gomphosis (Between teeth and adjacent bones also known as periodontal ligament
3. Syndesmosis (Two bones linked by a ligament)

Question 14

What are the type of cartilages joints?

Answer 14

1. Synchondrosis (Occurs when two ossification centers are separated)
2. Symphysis (Occur where two separate bones are connected by a cartilage)
