Chapter 9- Joints

Front 1

Fibrous Joints

Back 1

bones held together by dense collagen fibers

Front 2

Cartilaginous Joints

Back 2

bones held together by cartilidge

Front 3

Synovial Joint

Back 3

bones held together by ligiments

Front 4

List the three STRUCTURAL classifications of joints.

Back 4

Fibrous Joints
Cartilaginous Joints
Synovial Joints

Front 5

List the three FUNCTIONAL classifications of joints.

Back 5

Synarthrosis
Amphiarthrosis
Diarthrosis

Front 6

Synarthrosis

Back 6

an immovable joint

Front 7

Amphiarthrosis

Back 7

a slightly movable joint

Front 8

Diarthrosis

Back 8

a freely movable joint

Front 9

Fibrous Joints

Back 9

-Lack a synovial cavity
-held closely together by dense irregular connective tissue
-permit little to no movement

Front 10

Three types of Fibrous Joints

Back 10

-Sutures
-Syndesmoses
-Gomphoses

Front 11

Sutures

Back 11

Occur only between the bones of the skull

Front 12

Syndesmoses

Back 12

-Permit slight movement
-Interossesous membrane
-between the tibia and fibula of the the leg

Front 13

Gomphoses

Back 13

-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

Front 14

Cartilaginous Joints

Back 14

-Lack a synovial cavity
-allows little to no movement
-joint is tightly connected by either cartilidge

Front 15

Two types of Cartilaginous Joints

Back 15

-Synchondroses
-Symphyses

Front 16

Synchondroses

Back 16

-Connecting tissue in hyaline cartilidge
-Epiphyseal (growth) plate

Front 17

Symphyses

Back 17

-Slightly movable joint
-Ends of articulating bones, a fibrocartilage connects the bones.

Front 18

Pubic Symphyses

Back 18

Between the anterior surfaces of the hip bone

Intervetebral joints between the vertebraes.

Front 19

Synovial Joints

Back 19

Allows a joint to move freely

Ligaments hold bones together in synovial joint

Front 20

Articular Capsule

Back 20

a sleeve like capsule encloses the synovial cavity.

Front 21

Two layers of the Articular Capsule

Back 21

A outer fibrous capsule
An inner synovial membrane

Front 22

Synovial Fluid

Back 22

fluid sectreted by the synovial membrane

Front 23

Four Functions of Synovial Fluid

Back 23

-Lubricating the joint
-absorbing shocks
-supplying oxygen and nutrients to the cartilidge
-removing C02 and metabolic waste from the cartilidge.
