JOINTS are known as
|
ARTICULATION
|
|
Define JOINTS
|
The functional junctions between bones:
1) Enable wide variety of movements 2) Classified according to degree of movement and type of tissue that binds them together |
|
What are the 3 types of JOINTS: The functional classifications
(pg 11 Kinesiology text) |
1) SYNARTHRODIAL
2) AMPHIATHRODIAL 3) DIATHRODIAL |
|
SYNARTHRODIAL JOINTS
Made of: Movement: Examples: |
FIBROUS JOINT
NONE SUTURES |
|
AMPHIATHRODIAL JOINTS:
Made of: Movement: Examples: |
CARTILAGINOUS JOINT
SLIGHT INTERVERTEBRAL DISC, PELVIS SYMPHYSIS |
|
DIARTHRODIAL JOINTS:
Made of: Movement: |
SYNOVIAL JOINT
FREE *MOST JOINTS ARE THESE |
|
SYNOVIAL JOINTS
Describe 3 things |
*Articular ends are covered ARTICULAR CARTILAGE
*joint capsule consist of CONNECTIVE TISSUE outside that joins the PERIOSTEUM *Inner layer made of the SYNOVIAL MEMBRANE |
|
LIGAMENTS
|
hold JOINTS together (bone to bone attachement)
|
|
BURSAE
|
Act as SHOCK ABSORBER
found between bone and tendon filled w/SYNOVIAL FLUID |
|
SYNOVIAL FLUID
|
Egg white consistency
LUBRICATES the articulating surfaces Secreted by SYNOVIAL MEMBRANE |
|
BURSITIS
|
INFLAMMATION OF THE BURSAE. Usually from over use
|
|
Dislocation
|
Bones comes out of the joint
|
|
Sprain
|
Tearing of ligament:
from micro to extensive |
|
