Ch 1: Joints Flashcards
The union/articulation of two structures
joint
What are the 3 articulations of joints?
Cartilage to cartilage
Bone to bone
Bone to cartilage
Joints allow variable amounts of _________
movement
What are the functional classifications of joints?
Synarthroidial
Amphiarthrodial
Diarthrodial
What are the structural classification of joints?
Fibrous
Cartilaginous
Synovial
A _______ classification is an organization of the joints based on how much movement they allow
Functional
A ________ classification is an organization of joints based on how they are formed
Structural
What functional classification has the least movement? And which one has the most?
Amphiarthroidal
Diarthroidal
Synarthrodial
Least - synarthrodial
Most - diarthrodial
What structural classification has the least movement? And which one has the most?
Synovial
Cartilaginous
Fibrous
Least - fibrous
most - synovial
What is the most immovable type of joint? What is it typically bound together by?
Synarthrodial/Fibrous Joints
Fibrous tissue
What is an examples of a fibrous joint?
Suture in skull
Gomphosis: socket for tooth
What is the socket for tooth allows minimal amount of movement called?
Gomphosis (fibrous joint)
This joint allows limited (slight to moderate) movement
Amphiarthroidal/Cartilaginous joints
What provides the union between two bones in a amphiarthroidal/cartilaginous joints?
Cartilage
What are two examples of an amphiarthroidial/cartilaginous joint?
Synchondrosis joint and symphysis joint
A joint where bones are joined by or united to hyaline cartilage (i.e., stenocostal joint)
synchondrosis joint
The intervertebral disks are what type of joint?
Symphysis joint (i.e., amphiarthroidial/cartilaginous joint)
This joint always includes a joint cavity containing synovial fluid around which is an articular capsule
Diarthroidial/Synovial Joints
What is the most freely moveable joint type in the body?
Diarthroidial/Synovial Joints
What are examples of diarthroidial/synovial joints?
Cricothyroid Joint (pivot joint)
Cricoarytenoid joint (saddle joint)
Condyloidal joint
Medial Atlanto joint (a pivot joint)
What is the joint between the cricoid cartilage of the larynx and the thyroid cartilage of the larynx?
Cricothyroid joint (a pivot joint)
What is the structure and function of the cricothyroid joint?
structure: synovial joint
function: muscle contraction allows the cricoid cartilage to rotate upward and the thyroid cartilage to rotate downward
What is the joint between the cricoid cartilage of the larynx and the arytenoid cartilage of the larynx?
Cricoarytenoid joint (a saddle joint)
What is the structure and function of the cricoarytenoid joint?
structure: synovial joint
function: muscle contraction allows rocking of the arytenoid cartilage and sliding of the arytenoid cartilage??
