Chapter 9: Joints Flashcards
What are the functions that joints have
Synarthrosis
Amphiarthrosis
Diarthrosis
This is the name of a joint that is immovable
Synarthrosis
This is the name of a joint that is freely movable
Diarthrosis
This is the name of a joint that is slightly moveable
Amphiarthrosis
Structure of the joint ( connecting tissues between the neighboring bones)
Fibrous= Dense irregular connective tissue
Cartilaginous= Uses cartilage between bones
Synovial= Lubricated cavity that contains connective tissue and cartilage
What are Fibrous Joints
They are joints in which neighboring bones are joined together by a solid mass of dense irregular connective tissue
- Sutures
- Syndesmosis
- Gomphosis
What are Sutures
Fibrous joints composed of thin layer of dense irregular connective tissue called sutural ligament
- Adds strength
- Decrease any chances of fracturing
Function
- Important role as sites of growth
- Shock absorption for the skull
What is Syndesmosis
Permits limited movement
What is Gomphosis
Binds the root of the tooth to the alveolar socket, anchors the tooth to its socket in the jaw
What is Cartilaginous Joints
Solid connective tissue, that allows little or no movement
We have two types
Synchondrosis (Hyaline cartilage)
Symphysis ( Fibrocartilage)
What is Synchondroses
Hyaline cartilage, it is slightly immovable joint
What is Symphysis
Hyaline cartilage, All occur in the midline of the body
What are Synovial joints
Slightly moveable, are the most mobile joints of the body
They are between the carpal bones
Types of Synovial Joints we have
Planar Joint
Hinge Joint
Pivot Joint
Condyloid Joint
Saddle Joint
Ball and Socket
What is a Planar Joint
-Flat or slightly curved
