Answer 3

Hinge joint

Question 4

Name and describe this joint

Answer 4

Plane joint (intercarpal joint)

The bones of plane joints have flat articular surfaces that allow bones to glide past one another.

Question 5

Name and describe this joint

Answer 5

Ball-and-socket joint (shoulder joint)

Ball-and-socket joints are named for the rounded, ball-like end of one bone that fits into the concave “socket” of another bone.

Question 5

What type of joint somewhat resembles condyloid joints, but permit a greater range of motion?

Answer 5

Saddle joint

Question 6

What is the term used to describe joints that are immovable?

Answer 6

Question 8

What type of joint consists of a bone with a rounded projection that fits into the groove of another bone?

Answer 8

Question 8

The bones in a synovial joint are held together by _______ that further reinforce the joint.

Answer 8

ligaments

Question 9

Name and describe this joint

Answer 9

Pivot joint (proximal radioulnar joint)

In a pivot joint, one bone rotates or “pivots” around another bone. Generally, pivot joints consist of one bone with a rounded projection that fits into a groove of another bone.

Question 10

Name and describe this joint

Answer 10

Saddle joint (thumb carpometacarpal joint)

Saddle joints somewhat resemble condyloid joints but permit a greater range of motion

Question 12

What type of joint has bones that fit together much like the hinge of a door?

Answer 12

Hinge joint

Question 13

What is made of dense irregular collagenous connective tissue and provides strength and structural reinforcement for the joint? It is also lined by the synovial membrane.

Answer 13

Joint capsule

Question 14

The articulating ends of the bones are covered with _______, usually hyaline cartilage.

Answer 14

articular cartilage

Question 16

What type of joints are named for the rounded, ball-like end of one bone that fits into the concave “socket” of another bone?

Answer 16

Ball-and-socket joint

Question 17

______ are fibrocartilage pads that improve the fit of two bones to prevent dislocation.

Answer 17

Articular discs

Question 18

What provides a smooth, nearly frictionless surface for articulation?

Answer 18

Articular cartilage

Question 19

What are articular discs also known as?

Answer 19
