1

Collateral ligaments of the shoulder joint

The tendons of insertion of M. infraspinatus, M. supraspinatus and M. subscapularis

2

Lig glenohumerale laterale/mediale

Ligaments of the shoulder joint. Poorly developed thickenings of the fibrous part of the joint capsule

3

Transverse humeral ligament

Ligament of the shoulder joint. A collagenous thickening across the tendon of origin of m. biceps brachii at the intertubercular groove

4

The articulations of the Elbow joint

Humeroradial joint (Humeral capitulum and trochlea with head of Radius); Humeroulnar joint (Humeral trochlea with incisura trochlearis on the Ulna); Proximal Radioulnar joint (Circumferentia articularis radii with Incisura radialis on the Ulna)

5

Ligament collaterale cubiti lateraleqmediale

Ligaments of the elbow joint. Pronounced thickenings in the fibrous layer of the capsule. The beceps' and brachialis' tendons cover the distal portion of the medial collateral ligament

6

Ligament anulare radii

Ligament of the elbow joint. A thin band that runs transversely around the radius. It attaches to the lateral and medial coronoid processes of the Ulna. Lies deep to the collateral ligament

7

Ligament olecrani

Ligament of the elbow joint. An elastic ligament thet passes between the craniomedial aspect of the olecranon to the medial border of the olecrenon fossa

8

Ligament interosseum antebrachii

Ligament of the elbow joint. A condensation of collagenous tissue that units the radius and ulna proximally

9

Membrana interossea antebrachii

The dense membrane that connects the interosseus margins of the Radius and Ulna, forming the Radioulnar syndesmosis. It also separates between the exensor and flexor compartments of the forearm

10

Articulatio radioulnaris distalis

The distal radioulnar joint is formed between the circumferenca articularis ulnare and the incisura ulnaris of the Radius. Incorporated into the antebrachiocarpal joint.

11

Ligament radioulnare

Ligament of the distal radioulnar joint. This is a short lig. which tightly connects the cranial surfaces of the distal Radius and Ulna

12

Artriculations of the carpal joint

Antebrachiocarpal joint - most proximal, lies between the distal radius and ulna and the proximal row of carpal bones. Includes the distal radioulnar joint and the articulations of the accessory carpal bones; Middle carpal joint - lies between the proximal and distal rows of carpal bones; Carpometacarpal joint - most distal, lies between the distal row of carpal bones and the bases of the metacarpal bones. Includes the articulations between the bases of adjecent metacarpal bones

13

Fibrous joint

Without joint space; Little or no mobility

14

Cartilaginous joint

Without a joint space; limited mobility (streching, etc.)

15

Synovial joint

With a joint space; greater mobility

16

Synarthrosis

Another name for fibrous joint

17

Amphiarthrosis

Anoter name for cartilaginous joint

18

Diarthrosis

Another name for synovial joint

19

Syndesmoses

May include interosseus membrane. Example: Radius-Ulna

20

Sutures

Between flat bones of the skull

21

Gomphosis

Between tooth cementum and bone of dental alveoli

22

Hyaline cartilage joint

Mostly temporary. Example: growing plates

23

Fibrocartilaginous joint

Midline cartilage that connects two symetrical bones (Symphysis). Examples: Pelvis, Mandible

24

Synostosis

Fusion of bones. Example: cow's Radius and Ulna

25

Simple joint

Between two bones

26

Compound joint

More than two bones

27

Complex joint

Two bones or more + articular disc (fibrocartilaginous)

28

Gliding joint

Non-axial, plane. Example: vertebrates

29

Hinge joint (ginglymus)

Movement axis vertical to the longitudinal axis of the bones. Allows flexion/extension. Example: Elbow joint

30

Pivot joint

Rotation parrallel to the bone's longitudinal axis. Example: between the the Radius and Ulna (head of radius can rotate). Mostly pronation/supination movement

31

Sledge joint

Knee-cap

32

Saddle joint

Opposite surfaces are reciprocally concave-convex. The joint is bi-axial and allows flexion/extension, abduction/adduction and circumduction without axial rotation. Example: The base of the thumb

33

Condyloid/Elipsoid joint

An ovoid articular surface (condyle) that is recieved into an elliptical cavity. Permits movement in two planes: flexion/extension,  abduction/adduction and circumduction (all of the others together)

34

Spheroid joint

Also known as "Ball and Socket". The ball-shaped surface of one bone fits into the cup-like depression of another. Capable of motion around an idefinite number of axes. Example: pelvic joint

35

Ligament collateral carpi mediale

consists of two parts: the straight part runs from a tubercule above the radial styloid process to the most medial part of the intermedial carpal; the oblique part runs from the styloid process to the palmaromedial surface of the intermedioradial carpal

36

Ligament collaterale carpi laterale

Extends from the ulnar styloid process to the ulnar carpal

37

Extensor Retinaculum

Transversely oriented condensation of carpal fascia that aids in holding in grooves all the tendons that cross the dursum of the carpus

38

Flexor retinaculum

Modification of the palmar part of the carpal fascia. Attaches laterally to the medial part of the enlarged free palmar end of the accessory carpal bone and passes medially to the styloid processes and the palmar projections of the intermedioradial and first carpals

39

Carpal canal

Superficial border - superficial part of the flexor rtinaculum; Deep border - Palmar carpal fibrocartilage; Lateral border - the accessory carpal bone. Contains tendons and synovial sheaths, some veins and arteries and nerves.

40

Metacarpophalangeal joint

Between the distal end of a metacarpal bone, the proximal end of P1 and one (in digit I) or two (in digits II-V) sesamoid bones

41

Proxinal interphalangeal joint

Between the distal end of P1 and proximal end of P2. In digit I there is no P2, so this entire joint is missing

42

Distal interphalangeal joint

Between the distal end of P2 (P1 in digit I) and the base of P3. Supported by the subcutaneous cushion of the digital pad
