Lec. 8 Joints/ligaments Flashcards
1
Q
4 categories of types of movements at synovial joints
A
- gliding (side to side)
- angular (increase/decrease angle between bones - flexion/extension/abduction/adduction)
- rotation
- special movements
(Elevation & depression, protraction & retraction, upward & downward rotation, supination & pronation, inversion & eversion)
2
Q
What joint do the Tibia and Fibula make
A
Tibiofibular joint
3
Q
What joint do the Glenoid Cavity (scapula) and Humerus make
A
Glenohumeral joint
4
Q
What joint do the temporal bone and mandible make
A
Temporal mandibular joint
5
Q
What joint to the sacrum and ilium (hip bone) make
A
Sacroiliac joint
6
Q
What joint do the metacarpal and proximal phalanx make
A
Metacarpophalangeal joint
7
Q
Joints are classified _____ and ______
A
Structurally (anatomical characteristics)
Functionally ( type of movement)
8
Q
What are the structural classification of joints
A
- fibrous
(bones held together by connective tissue) - cartilagenous
(Bones held together by cartilage) - synovial
(Has synovial cavity & held together by an articular capsule)
9
Q
What are the functional classifications of joints
A
- synarthrosis = immovable
- amphiarthrosis = slightly moveable
- diarthrosis = freely movable (synovial joints only)
10
Q
3 types of fibrous joints in body
A
- suture (connects bones in skull)
[In adults: amphiarthrosis = slightly moveable] - syndesmosis (joints between teeth and the mandible and maxilla, and the tibiofibular joint)
[amphiarthrosis = slightly moveable] - interosseous membrane (between bones in forearm and leg) [amphiarthrosis = slightly moveable]
11
Q
2 types of cartilagenous joints in body
A
- synchondrosis (1st sternocostal joint and epiphyseal growth plates) [synarthrosis = immovable] - symphysis (Pubic symphysis & intervertebral discs) [amphiarthrosis = slightly moveable]
