Flashcards in Arthrology Deck (33):
1

Congruency Functional Continuum

Mobility Stability

Mobility loose binding tissues
Poor Bony Congruency
Multiplanar movement

Stability - Tight binding tissues
Good boney congruency
No or uni-planar movement

2

DAS

Diarthroses
Amphiarthroses
Synarthroses

3

Diarthroses

Very mobile, Poor boney congruency, multiplanar movement most commonly synovial joints.

Ex. The glenohumeral joint

4

Amphiarthroses

Tight binding tissues, good bony congruency, very little movement.

Ex. pubic symphysis

5

Synarthroses

Tight binding tissue, good boney congruecy, no movement.

Ex. Skull sutures.

6

Categories of Joints Based on Binding Tissue

Synovial
Cartilaginous
Fibrous

7

Types of Fibrous Joints

Sutures
Syndesmoses
Gomphoses

All of the fibrous joints are made of Dense fibrous connective tissue.

8

Types of Cartilaginous Joints

Synchondroses
Symphsis

9

Suture Joints

Joints of the skull, like a jidsaw puzzles.

Allows no movement.

Made of dense fibrous connective tissue.

10

Syndesmoses

Made out of dense Fibrous connective tissue.

Found in interosseous membranes in the radius and ulna and the tibia and fibula.

11

Gomphoses

Made out of dense fibrous connective tissue.

Found only in the teeth.

12

Synchondroses

Made out of hyalin cartilage.

Found in epiphyseal growth plates and in the joint joining the sternum and the first rib.

Other ribs form synovial capsules.

13

Symphsis

Made out of Fibrocartilage.

Pubic Symphsis

14

Synovial Joints

Has a fibrous joint capsule (Binding Tissue).
It is made out of dense Irregular connective tissue.

There is cartilage within these fibrous joint capsules, depend on the joint but mostly all have hyalin

15

Synovial Membrane

A membrane within the Fibrous joint capsule that produces synovial fluid.

16

Synovial Fluid Functions

Reduces friction associated with movement. Lubricates the joint.

Nourishes articular cartilage.

17

Fibrocartilage pads Functions

These pads arent in every joint.

Increase bony fit/congruency

Reduces compressional stress.

18

Ligaments

Intrinsic: completely within the joint
Extrinsic: Completely Outside of the joint
Capsular: continuous with the joint capsule, thickening of the joint capsule.

19

Types of synovial Joints

Plane
HInge
Pivot
Condyloid
Saddle
Call and Socket

20

Plane Joint

Surfaces are flat and allowing glide.

Allows only translation.

Carpals

21

Hinge

Cylindrical end conforms to trough-shaped end allowing motion flexion/extension.

Elbow, knee

22

Pivot

Rounded end conforms to a sleeve or ring of bone or ligaments allowing only rotation.

Radio ulnar joint proximal.

23

Condyloid/Ellipsoid

Oval surface of one bone fits to complementary depression of another bone allowing all angular motions.

Biaxail

Radio carpal joint

24

Saddle

Resemble condyloid joint but bone ends have both concave and convex surfaces that fit together to allow more movement.

Biaxial joint.

CMC of thumb.

25

Ball and Socket

Sperical/hemispherical head articulate with a cuplike socket allowing multi-axial movements.

GH joint

26

Osteokinematics

Movement between bone relative to sagittal, frontal, and tranverse planes (joint rotations)

Axis of Rotations

27

Arthokinematics

Movement at the articular surfaces between bones.

Roll, Glide and Spin

28

Frontal Plane Axis

Anterior/posterior

29

Sagittal Plane Axis

Medial/Lateral

30

Transverse Plane Axis

Superior/Inferior (longitudinal).

31

Roll

Multiple point along one rotation ariticular surface contacting multiple points on another articular surface.

Wheel

32

Slide

A single point on one articular surface contacting multiple points on another articular surface.

Ice skate

33

Spin

A single point on one articular surface rotates on a single point on another articular surface.

Spinning a quarter.
