What is an articulation?
the place of contact between bones, between bone and cartilage, or between bones and teeth.
What is the study of joints called?
Arthrology.
What is Kinesiology?
The Study of the functional relationship or biomechanics of the skeleton, joints, muscles, nerves.
T or F?

The more mobile a joint is the less stable it is, while if a joint is immovable it is very stable.
True.
What are the three types of structural joints?
Fibrous, cartilaginous, and synovial joints.

True.
What are the tree types of structural joints?
Fibrous, cartilaginous, and synovial joints.
What are fibrous joints?
They lack a joint cavity and are held together by dense (fibrous) connective tissue.
What are cartilaginous joints?
They lack a joint cavity and the bones are joined together by cartilage.
What are synovial joints?
They HAVE a fluid filled joint cavity that separates the articulating surfaces of the bones and these articulating surfaces are enclosed within a capsule and supported by ligaments.
What are the three types of functional joints?
Synarthroses, amphiarthroses, diarthroses.
What are synarthrose joints?
immovable joints

ex:sutures.
What are amphiarthrose joints?
Slightly movable joints.

ex:pubic symphysis.
What are diarthrose joints?
freely movable joints.

ex: ball and socket joints.
Our body is said to be..... (joints)
diarthrose synovial joints
What are Pseudoarthroses?
False joints that occur when a fractured long bone heals as two separate bones.
What are three types of fibrous joints?
Gomphoses, sutures, syndesmoses.

What are three types of fibrous joints?
Gomphoses, sutures, syndesmoses.
Describe gomphoses jonts.
A fibrous joint, which are only in the articulations of the roots of the individual teeth with the sockets of the mandible and maxillae. The tooth is held in place by fibrous "peridontal ligaments". This joint is classified as SYNARTHROSIS.
Describe suture jonts.
Immovable fibrous joints that are only found between certain bones of the skull. Sutures form at around 15-24 months. COMPLETELY OSSIFIED SUTURES BECOME SYNOSTOSES.
Describe syndesmoses joints.
Fibrous joints in which articulating bones are joined by long strands of dense regular connective tissue only. They provide slight movement so they are classified at AMPHIARTHROSES. Are found betwwen the shafts of the radius and ulna, tibia and fibula. These bones are held together by broad ligamentous sheet called an INTEROSSEOUS MEMBRANE.
Name the two types of cartilaginous joints.
Synchondroses and symphyses.

(chondro:cartilage)
Describe synchondroses joints.
Held together by hyaline cartilage. Are classified as synarthroses.

Ex: epiphyseal growth plates in children.

Costochondral articulations between most of the ribs and the sternum.
Describe symphyses joints.
They have a pad of fibrocartilage between the articulating bones. Fibrocartilage act as shock absorbers. Are classified as AMPHIARTHROSES.

EX: symphysis pubis
intervertebral joints formed by the bodies of adjacent vertebrae and the intervertebral discs.
