ECPI 2020: ANATOMY & PHYSIOLOGY
EXAM UNIT 3 (CH. 8-11):UPDATED
ACTUAL Questions and CORRECT
Answers
Joints: - CORRECT ANSWER - - Articulations
- Bones coming together, so the joint can make the movement.


Structural Classification of Joints: - CORRECT ANSWER - 1. Fibrous joints: Syndesmosis,
suture, gomphosis
2. Cartilaginous joints:
3. Synovial joints:


Functional Classification of Joints: - CORRECT ANSWER - 1. Synarthrotic: immoveable
2. Amphiarthrotic: slightly moveable
3. Diarthrotic: Freely moving


Fibrous Joints: - CORRECT ANSWER - 3 types:
- Syndesmosis
- Suture
- Gomphosis


Syndesmosis: - CORRECT ANSWER - - Fibrous joint
- Fibrous membrane that connects bones
- Amphiarthrotic (slightly moveable)
- Ex: interosseous membrane, interosseous ligament, in between radius and ulna in forearm, in
between tibia and fibula in leg

,Suture: - CORRECT ANSWER - - In between skull bones
- Synarthrotic (immoveable)


Gomphosis: - CORRECT ANSWER - - Joint between teeth and jaw bone (holds teeth
together)
- Peridontal ligament links the tooth with jaw bone
- Synarthrotic (immoveable)


Cartilaginous Joints: - CORRECT ANSWER - 2 types:
- Synchondrosis
- Symphysis


Synchondrosis: - CORRECT ANSWER - - Hyaline cartilage that links bones together
2 places:
- between rib and sternum (linking them)
- synarthrotic (immoveable)
- Ex. Epyphyseal line - temporary until bone stops growth


Symphysis: - CORRECT ANSWER - - Fibrocartilage joint
- Ex: intervertebral discs & Pubic symphysis (link between 2 pubic bones)
- Amphiarthrotic (slight movement)


Pubic Symphysis: - CORRECT ANSWER - - Joint that does not move except when giving
birth (pregnant women feel pain because this joint usually does not move)


Joints can permit the bones to grow? - CORRECT ANSWER - Yes, because of synchondrosis



Endochondral Ossification: - CORRECT ANSWER - All long bones are hyaline cartilage

, Synovial Joints: - CORRECT ANSWER - - Diarthrotic (freely moveable)



6 Types of Synovial Joint Classifications: - CORRECT ANSWER - 1. Ball-and-Socket Joint
2. Condylar Joint
3. Plane Joint
4. Hinge Joint
5. Pivot Joint
6. Saddle Joint


Ball-and-Socket Joint: - CORRECT ANSWER - Also called spheroidal joint
- Synovial joint
- In hip and shoulder
- Multiaxial


Hinge Joint: - CORRECT ANSWER - - Synovial joint
- In elbow, knee
- Uniaxial (in 1 plane)


Plane Joint: - CORRECT ANSWER - Also called gliding joint
- Synovial joint
- Carpal bones, tarsal bones
- Nonaxial


Condylar Joint: - CORRECT ANSWER - Also called ellipsoidal joint
- Synovial joint
- Between metacarpals and phallanges
- Biaxial movement
