Q

Dorsiflextion

A

Flexing the ankle so that the foot moves anteriorly in the sagittal plane.

24
Q

Plantarflexion

A

26
Q

Supination (foot/ankle)

A

Combined movements of adduction and inversion resulting in raising of the medial margin of the foot.

27
Q

Synovial Joints have 5 distinct features

A
  1. Enclosed by fibrous joint capsule.
  2. The joint capsule encloses the joint cavity.
  3. The joint cavity is lined with synovial membrane.
  4. Synovial fluid occupies the joint cavity.
  5. The articulating surfaces of the bones are covered with hyaline cartilage, which helps absorb shock and reduces friction.
28
Q

Joints are classified as:

A
  1. Synarthrodial (sutures of the skull)- do not move appreciably.
  2. Amphiarthrodial move slightly and are held together by ligaments (syndesmosis- inferior tibiofibular joint) or fibrocartilage (synchondrosis- pubic symphysis)
  3. Diarthrodial (Synovial)- only joints that contain articular cavity, synovial membrane and synovial fluid.

S-ynarthrodial
A-mphiarthrodial
D-iarthrodial

29
Q

Suture joint- type and example

A

Fibrous- tight union unique to the skull

30
Q

Syndesmosis joint- type and example

A

Fibrous- Interosseous membrane between bones (the union along the shafts of the radius and ulna, tibia and fibula, and the distal tibiofibular joint)

31
Q

Gomphosis joint- type and example

A

Fibrous- Unique joint at the tooth socket

32
Q

Primary Joint (synchondroses; hyaline cartilaginous)- type and example

A

Cartilaginous- Usually temporary to permit bone growth and typically fuse (epiphyseal plates); some do not (at the sternum and rib)

33
Q

Secondary joint (symphyses; fibrocartilaginous)- type and example

A

Cartilaginous- Strong, slightly movable joints (intervertebral discs, pubic symphysis)

34
Q

Plane (arthrodial) Joint- type and example

A

Synovial- Gliding and sliding movements (acromioclavicular joint)

35
Q

Hinge (ginglymus) Joint- type and example

A

Synovial- Uniaxial movements (elbow extension and flexion)

36
Q

Ellipsoidal (condyloid) Joint- type and example

A

Synovial- Biaxial joint (radiocarpal extension, flexion at the wrist)

37
Q

Saddle (sellar) Joint- type and example

A

Synovial- Unique joint that permits movements in all planes, including opposition (the carpometacarpal joint of the thumb)

38
Q

Ball and socket (enarthrodial) Joint- type and example

A

Synovial- Multiaxial joints that permit movements in all directions (hip and shoulder joints)

39
Q

Pivot (trochoidal) Joint- type and example

A

Synovial- Uniaxial joints that permit rotation (proximal radioulnar and atlantoaxial joints)

40
Q

Bicondylar Joint- type and example

A

Synovial- Allow movement primarily around one axis with some limited rotation in a second axis (knee flexion and extension with limited internal and external rotation)
