Upper Extremity Articulation
The Point of articulation between the ulnar notch of radius and head of the ulna
Distal Radioulnar
Located between the 8 carpal bones are stabilized by numerous ligaments. Movements are generally gliding, with some ABDuction
and flexion
Intercarpal & Midcarpal Joints
Funny Bone
The ulnar nerve runs between the olecranon process and the medial epicondyle
The joint between the head of the humerus and the glenoid cavity
Glenohumeral Joint
Lateral articulation of capitulum of the humerus with the head of the radius
Humeroradial Joint
Radioulnar Joint movements
Permits pronation and supination of the forearm.
Joints in the hand
Carpometacarpal joints (CMC joints)
Metacarpophalangeal joints (MCP joints)
Interphalangeal joints (IP joints)
Articulation of
the sternum and clavicle
Sternoclavicular Joint
Medial articulation of trochlea of the humerus with the trochlear notch of the ulna.
Humeroulnar Joint
most numerous and anatomically complex joint
Synovial Joints
What articulations make up the wrist joint?
Radiocarpal joint
Intercarpal/Midcarpal joints
Between the head of the radius and radial notch of the ulna
Proximal Radioulnar Joint
Articulation of the acromion process of the scapula and the clavicle
Acromioclavicular Joint
Lays directly with the carpal bones(scaphoid and lunate) distally
Only the radius articulates
Synovial Functional classification
Diarthroses
3 types of Fibrous joints
Syndesmoses= distal radius & Ulna Distal tibia & fibula
Sutures =Found only in the skull
Gomphoses = Formed between the root
of a tooth and the sockets of the mandible.
2 types of Cartilaginous Joints
Synchondroses= Epiphyseal plate, Between 1st rib & manubrium
Symphyses= Pubic symphysis, Articulation between
vertebrae
Joint with no cavity, fits closely, and permits little or no movement.
Fibrous
Angular Movements
▫Increase or decrease in the angle between the bones
▫Flexion, extension, abduction, adduction, lateral flexion
3 types of synovial joints and examples
Biaxial= saddle joint
Uniaxial= Hinge, pivot joint
multiaxial= Gliding joint
Special movements that synovial joints can do
▫Occur only in certain joints
▫Include: elevation/depression, protraction/retraction, inversion/eversion, dorsiflexion/plantarflexion, supination/pronation, and opposition
Immovable
Fibrous (Synarthroses)
Slightly movable
Cartilaginous (Amphiarthroses)
Freely movable
Synovial (Diarthroses)
location of gliding joint
Intervertebral joints
