Study Notes
Synovial Joints
-
Synovial Plane Joints: Allow gliding movements.
- Intercarpal joint: Located between carpal bones at the wrist.
- Intertarsal joint: Found between tarsal bones at the ankle.
- Sternoclavicular joint: Connects the manubrium of the sternum with the clavicle.
- Acromioclavicular joint: Joins the acromion of the scapula and the clavicle.
- Sternocostal joint: Links the sternum with the costal cartilages of the second to seventh ribs.
- Vertebrocostal joints: Formed between rib heads/tubercles and thoracic vertebrae.
-
Synovial Modified Hinge Joint: Allows flexion and extension with slight rotational movement.
- Knee joint: Complex joint allowing for both bending and a degree of rotation.
-
Synovial Hinge Joints: Permit movement in one plane (flexion and extension).
- Elbow joint: Classic hinge joint connecting the humerus with the radius and ulna.
- Ankle joint: Allows for dorsiflexion and plantarflexion movements.
- Interphalangeal joints: Joints between finger and toe phalanges.
-
Synovial Pivot Joints: Permit rotational movement around a single axis.
- Atlanto-axial joint: Allows head rotation, essential for "no" movement.
- Radioulnar joint: Enables rotation from palm facing down (pronation) to up (supination).
-
Synovial Condyloid Joints: Allow movement but restrict rotation.
- Radiocarpal joint: Connects the radius and carpal bones allowing wrist movements.
- Metacarpophalangeal joints II-V: Joints between metacarpals and proximal phalanges.
-
Synovial Saddle Joint: Allows for movement in two planes.
- Carpometacarpal joint: Between the trapezium bone and metacarpal I, critical for thumb mobility.
-
Synovial Ball-and-Socket Joints: Enable a wide range of motion including rotational.
- Shoulder joint: Humeral head fits into the glenoid cavity of the scapula.
- Hip joint: Femoral head fits into the acetabulum of the pelvis, supporting weight and facilitating a range of movements.
Fibrous Joints
-
Fibrous Sutures: Immovable joints united by connective tissue.
- Coronal suture: The fibrous joint between the frontal and parietal bones of the skull.
-
Fibrous Syndesmosis: Slightly movable joints where bones are connected by ligaments.
- Distal tibiofibular joint: Connects the tibia and fibula near the ankle, allowing limited movement.
-
Fibrous Interosseous Membrane: A type of syndesmosis.
- Found between the tibia and fibula, providing stability and support.
Cartilaginous Joints
-
Cartilaginous Synchondrosis: Joints where bones are joined by hyaline cartilage.
- Epiphyseal plate: Found between the diaphysis and epiphysis of long bones, crucial for growth during development.
-
Cartilaginous Symphysis: Joints where fibrocartilage is present.
- Pubic symphysis: Located between the pubic bones, allows slight movement.
- Intervertebral joints: Connect the vertebrae with fibrocartilage, aiding shock absorption and flexibility.
