|
bones held together by dense collagen fibers
|
|
Cartilaginous Joints
|
bones held together by cartilidge
|
|

|
bones held together by ligiments
|
|
List the three STRUCTURAL classifications of joints.
|
Fibrous Joints
Cartilaginous Joints Synovial Joints |
|
List the three FUNCTIONAL classifications of joints.
|
Synarthrosis
Amphiarthrosis Diarthrosis |
|
Synarthrosis
|
an immovable joint
|
|
Amphiarthrosis
|
a slightly movable joint
|
|
Diarthrosis
|
a freely movable joint
|
|
Fibrous Joints
|
-Lack a synovial cavity
-held closely together by dense irregular connective tissue -permit little to no movement |
|
Three types of Fibrous Joints
|
-Sutures
-Syndesmoses -Gomphoses |
|
Sutures
|
Occur only between the bones of the skull
|
|
Syndesmoses
|
-Permit slight movement
-Interossesous membrane -between the tibia and fibula of the the leg |
|
Gomphoses
|
-Immovable joint
-Joint in which a cone shaped peg fits into a socket -articulations of the teeth with the sockets of the maxillae and mandible |
|
Cartilaginous Joints
|
-Lack a synovial cavity
-allows little to no movement -joint is tightly connected by either cartilidge |
|
Two types of Cartilaginous Joints
|
-Synchondroses
-Symphyses |
|
Synchondroses
|
-Connecting tissue in hyaline cartilidge
-Epiphyseal (growth) plate |
|
Symphyses
|
-Slightly movable joint
-Ends of articulating bones, a fibrocartilage connects the bones. |
|
Pubic Symphyses
|
Between the anterior surfaces of the hip bone
Intervetebral joints between the vertebraes. |
|
Synovial Joints
|
Allows a joint to move freely
Ligaments hold bones together in synovial joint |
|
Articular Capsule
|
a sleeve like capsule encloses the synovial cavity.
|
|
Two layers of the Articular Capsule
|
A outer fibrous capsule
An inner synovial membrane |
|
Synovial Fluid
|
fluid sectreted by the synovial membrane
|
|
Four Functions of Synovial Fluid
|
-Lubricating the joint
-absorbing shocks -supplying oxygen and nutrients to the cartilidge -removing C02 and metabolic waste from the cartilidge. |
