Q

Synchondroses

A

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.

Q

Synovial Joints

A

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

Q

Synovial Fluid Functions

A

Reduces friction associated with movement. Lubricates the joint.

Nourishes articular cartilage.

17
Q

Fibrocartilage pads Functions

A

These pads arent in every joint.

Increase bony fit/congruency

Reduces compressional stress.

18
Q

Ligaments

A

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

19
Q

Types of synovial Joints

A
Plane
HInge
Pivot
Condyloid
Saddle
Call and Socket
20
Q

Plane Joint

A

Surfaces are flat and allowing glide.

Allows only translation.

Carpals

21
Q

Hinge

A

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

Elbow, knee

22
Q

Pivot

A

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

Radio ulnar joint proximal.

23
Q

Condyloid/Ellipsoid

A

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

Biaxail

Radio carpal joint

24
Q

Saddle

A

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
Q

Ball and Socket

A

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

GH joint

26
Q

Osteokinematics

A

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

Axis of Rotations

27
Q

Arthokinematics

A

Movement at the articular surfaces between bones.

Roll, Glide and Spin

28
Q

Frontal Plane Axis

A

Anterior/posterior

29
Q

Sagittal Plane Axis

A

Medial/Lateral

30
Q

Transverse Plane Axis

A

Superior/Inferior (longitudinal).

31
Q

Roll

A

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

Wheel

32
Q

Slide

A

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

Ice skate

33
Q

Spin

A

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

Spinning a quarter.
