Question 1

Types of joints:

Answer 1

1. Fibrous joints - immovable/fixed (protection) (Ex. Skull)
2. Cartilaginous joints- slightly movable (slight protection)
   (Ex. Cartilage in nose or ribs)
3. Synovial joints - movable

Question 2

Fibrous joints

Answer 2

immovable/fixed (a lot of protection)
(Ex. Skull)

Question 3

Cartilaginous joints

Answer 3

slightly movable (slight protection)
(Ex. Cartilage in nose or ribs)

Question 4

Answer 4

movable
(Ex. Limb connectors)

Ball and socket - Ex. Shoulder, hip

Gliding - Ex. Tarsals (hands and feet)

Hinge - Ex. Knee, elbow

Pivot - Ex. Neck

Saddle joints (looks like a horse saddle) (Ex. Thumb)

Ellipsoid joints 2 bowls in eachother (Ex. Wrist)

  -EX. Thumb

Question 11

Question 12

Periosteum

Answer 12

Outside lining of the bone which connects the tendon to the muscle. (Peri=surrounding & osteo=bone)

Question 13

Joint cavity

Answer 13

Space between the bones in a synovial joint.
It is filled with synovial fluid which acts as lubricant that smoothes and provides nutrients.

Question 14

Joint capsule

Answer 14

Bag-like outer structure surrounding the joint to protect the structure within.
Allows certain nutrients to pass through its membrane into the joint.

Question 15

Tendons

Answer 15

MUSCLE TO BONE
Located in each end of skeletal muscles and cross joint to attach to bones

Question 16

Ligaments

Answer 16

BONE TO BONE
Thick fibrous tissue bands helping the joint capsule and preventing dislocation in regular movement.

Question 17

Articular cartilage

Answer 17

Cartilage on end of bone that contact with each other instead of direct bone to reduce friction and allow smooth contact surface.
