ECPI 2024: ANATOMY & PHYSIOLOGYEXAM UNIT 3 (CH. 8-11) QUESTIONS
WITH COMPLETE SOLUTIONS
Joints: - Answer-- Articulations
- Bones coming together, so the joint can make the movement.
Structural Classification of Joints: - Answer-1. Fibrous joints: Syndesmosis, suture,
gomphosis
2. Cartilaginous joints:
3. Synovial joints:
Functional Classification of Joints: - Answer-1. Synarthrotic: immoveable
2. Amphiarthrotic: slightly moveable
3. Diarthrotic: Freely moving
Fibrous Joints: - Answer-3 types:
- Syndesmosis
- Suture
- Gomphosis
Syndesmosis: - 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: - Answer-- In between skull bones
- Synarthrotic (immoveable)
Gomphosis: - Answer-- Joint between teeth and jaw bone (holds teeth together)
- Peridontal ligament links the tooth with jaw bone
- Synarthrotic (immoveable)
Cartilaginous Joints: - Answer-2 types:
- Synchondrosis
- Symphysis
Synchondrosis: - 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: - Answer-- Fibrocartilage joint
- Ex: intervertebral discs & Pubic symphysis (link between 2 pubic bones)
- Amphiarthrotic (slight movement)
Pubic Symphysis: - 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? - Answer-Yes, because of synchondrosis
Endochondral Ossification: - Answer-All long bones are hyaline cartilage
Synovial Joints: - Answer-- Diarthrotic (freely moveable)
6 Types of Synovial Joint Classifications: - 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: - Answer-Also called spheroidal joint
- Synovial joint
- In hip and shoulder
- Multiaxial
Hinge Joint: - Answer-- Synovial joint
- In elbow, knee
- Uniaxial (in 1 plane)
Plane Joint: - Answer-Also called gliding joint
- Synovial joint
- Carpal bones, tarsal bones
- Nonaxial
Condylar Joint: - Answer-Also called ellipsoidal joint
- Synovial joint
- Between metacarpals and phallanges
- Biaxial movement
Pivot Joint: - Answer-Also called trochoid joint
- Synovial joint
- Uniaxial
- Movement around an axis (like what happens in between head of radius and ulna and
between C1 and C2)
