Question 1

What is a acromioclavicular joint?

Question 2

What is atlantoaxial joint?

Answer 2

The joint between the first two vertebrae, the bones of the spine

Question 3

What is a ball-and-socket joint?

Answer 3

A rounded protuberance on the end of one bone in that joint that fits into a cup-shaped indentation on the end of the other bone in the joint

protuberance = bump

Question 4

What is carpometacarpal joint?

Answer 4

Where the carpal bones connects to the end of the metacarpal bone that leads to the thumb

-is a saddle joint

Question 5

What are condyloid joints?

Answer 5

The end of one bone in the joint curves outward and the end of the other bone in the joint curves inward

-Motion along two plains
ex. toes

Question 6

What is a gliding joint?

Answer 6

Joints where two bones coming together are flat and slide past each other (plane joints)

• enables sliding motion in multiple directions (no rotations)
  ex.
  acromioclavicular (AC) joint

Question 7

What is a hip joint?

Answer 7

Where the femur meets the pelvic bone

(ball-and-socket joint)

Question 8

What is a metacarpophalangeal joint?

Answer 8

Joint between metacarpal & proximal phalange that allows wiggling movement

-enables motion along 2 planes (one outward and one inward)

(condyloid joint)

Question 9

What are pivot joints?

Answer 9

When one bone twists around another bone (rotational joints)

ex. atlantoaxial joints (allows head to move side to side)

Question 10

What is a saddle joint?

Answer 10

The end of one bone curves outward and the end of the other bone curves inward like two u-shapes hooked together

ex. thumb
