Completely separates joints
Tougher, sock absorber

That joints these joints together?
1 dof
Pivot
Distal ulna head stays put, distal MEDIAL radius pivots around in opposite (convex onto concave)

Tfcc
Ttcc
Triangular firbrocartilaginous complex
A ligament that binds the distal ends ulna and radius together.

Joint type
Dof
Action to confirm
Pivot
1dof
Supination pronation
Annular ligament
Articulating with
Ligament that attached to it
Head of the radius & radial notch on ulna
The radius head sits inside so it doesn’t slide everywhere
Radial collateral ligament
Carrying angle
Who had a larger angle and why
Women
Hips
Ulnar nerve location
Feels like
Medial Epicondyle (posterior) to the olecranon
Feels like a string

Functional joint classifications
3 & meaning
Synarthrodial
Amphiarthrolial
Diathrodial
3 structural classification of joints
Fibrous
Cartilaginous
Synovial
Fibrous joints
3
Suture - skulls suture - (synarthrodial)
Syndesmosis - ulnar and radius between (amphiarthrodial)
Gomphosis - tooth cavity (synarthrodial)
Cartilaginous joint types
Symchondrosis - primary cartilaginous joint Ossification Hyaline Epiphyseal growth plate
Symphysis - secondary cartilaginous joint Allows tendons to attach Ligaments to attach Mobile throughout life
Synovial
Hyaline cartilage
Joint capsule
Filled with synovial fluid, accessory ligaments
Menisci
Partial separation of firbrocartilaginous disc
Eg
Fumur tibia
Congruency
Fits better together
Tendon sheath
Surrounds tendons
Allows for smooth movement
Biceps with intertubercular groove
What determines the movement of bones
The shape of the articulating surface
Kinematics
Study of body movement in space
Radio carpal joint
Type of joint
Dof
Articulating surfaces
Condyle ( oval carpals convex on distal radius concave)
2 dof
Flex extend ulnar and radial deviate (circumduction)
Ulna does not participate
Scaphoid / lunate / with distal radius and tfcc
