-Science of joints
-branch of anatomy that deals with joints and ligamnets |
|
|
Term
|
Definition
| -Study of ligaments,joints, their movement and their disorders |
|
|
Term
|
Definition
| Description of movement of bone surfaces within a joint when bone moves through ROM ie movement of joint surfaces |
|
|
Term
| 3 types of Arthrokinematic movement |
|
Definition
1.Rolling or rocking
2.Sliding or gliding
3.Spinning
Most normal joint movemement has a combination of the 3. |
|
|
Term
|
Definition
-Bone movement when bone swings through a ROM around a joint axis, i.e. movement of shaft bones.
-Rotary motion produced w/most movements of shaft bones ex flex, ext, abd/add.
-use goniometer to measure osteokinematic movement |
|
|
Term
|
Definition
| -Connection between 2 bones |
|
|
Term
| 3 characteristics of joints |
|
Definition
1.Allow motion
2.Bear weight of the body
3.Provide stability |
|
|
Term
| Amount of joint movement depends on these 2 things: |
|
Definition
1.Shape of the bone ends
2.Articular surfaces |
|
|
Term
|
Definition
Fibrous connective tissue interlaces for strength and flexibility NOT elasticity.
-connects bone to bone |
|
|
Term
|
Definition
| Protective covering over a joint. |
|
|
Term
| 2 Layers of joint capsule |
|
Definition
1.Outer layer is fibrous (supports & protects)
2.Inner layer lined w/ synovial membrane & secretes synovial fluid |
|
|
Term
|
Definition
a fibrous membrane that lines the inner surface of articular capsules and serve as a joint "cushion"
-keeps joint freely moveable
-reduces friction |
|
|
Term
|
Definition
-fills and lubricates synovial membrane
-thick, viscous, alkaline fluid that looks like an egg-white.
-membrane formes a "film" over the articular cartilages and serves to lubricate. |
|
|
Term
|
Definition
-Dense fibrous connective tissue, resembles gristle.
-can withstand great amounts of pressure/tension. |
|
|
Term
|
Definition
1.Hyaline
2.White fibrocartilage
3.Yellow or elastic cartilage |
|
|
Term
| Characteristics of hylaline cartilage |
|
Definition
-Elastic, firm and bluish in color, found on articular ends of long bones
-NO blood or nerve supply
-Nutrition from synovial fluid
-Provides smooth articular surface. |
|
|
Term
| Characteristics of White Fibrocartilage |
|
Definition
-mixed white fibrous tissue, acts as a shock absorber
a. interarticular - found @ wrist, knee(meniscus)
b.Connecting-between vertebral bodies (intervertebral discs)
c.Circumferential-glenoid labrum to deepen socket
d.Stratiform-found in tendons of some muscles(tibialis posterior-where it glides over bone). |
|
|
Term
| Characteristics of Yellow or elastic fibrocartilage |
|
Definition
| -cartilage of larynx, epiglottis, eustachian tube, also symphasis pubis to allow for the birth of a child. |
