Joints and Muscles Flashcards
1
Q
What are the 7 joints?
A
- Ball and Socket
- Hinge
- Pivot
- Condyloid
- Saddle
- Gliding
- Fixed
2
Q
Ball and Socket?
A
- Hip; Shoulder
- A joint in which the rounded surface of a bone moves within a depression on another bone, allowing greater freedom of movement than any other kind of joint.
3
Q
Hinge?
A
- Elbow
- A type of synovial joint that exists in the body and serves to allow motion primarily in one plane.
4
Q
Pivot?
A
- Neck
- Allows only rotary movement
5
Q
Condyloid?
A
- Radial/Carpal (wrist)
- Although similar to a ball and socket joint, condyloid joints only allow for forward-backward and side-to-side movement and do not allow rotation.
6
Q
Saddle?
A
- Thumb
- Allows movements on two planes–flexion or extension and abduction or adduction.
7
Q
Gliding?
A
- Clavicle; Hand; Foot
- Formed between two bones in which the articular, or free, surfaces of the bones are flat or nearly flat, enabling the bones to slide over each other.
8
Q
Fixed?
A
- Skull
- Joints that provide stability to certain areas of the body
9
Q
Abduction?
A
Movement away from the mid-line of the body
10
Q
Adduction?
A
Movement towards the mid-line of the body
11
Q
Extension?
A
Straightening limbs at a joint
12
Q
Flexion?
A
Bending the limb at a joint
13
Q
Supination?
A
Overturned arm (palm upward)
14
Q
Pronation?
A
Overturned arm (palm downward)
15
Q
Circumduction?
A
Round movements e.g. wrist movement in circles
