Ch. 9 Joints
What is the cause of Costochondritis?
- Cause is usually unknown - Can be trauma or infection
What are 3 STRUCTURAL classes of joints?
- Fibrous joints - Cartilaginous joints - Synovial joints
What are the 3 most common types of Fibrous joints?
- Gomphoses - Sutures - Syndesmoses
What are the 2 classifications of Cartilaginous joints?
- Hyaline Cartilage - Fibrocartilage
What does it mean to have an Inverse relationship b/w mobility and stability?
- Inverse means "opposite directions" - The MORE STABILITY you have at the joint, the LESS MOBILITY you have at the joint. - The MORE MOBILITY you have at the joint, the LESS STABILITY at the joint.
What are Interosseous membranes?
A broad ligamentous sheet b/w bones.
How would you describe Gomphoses joints?
A peg in a socket
What is the Functional classification for Syndesmoses joints?
Amphiarthroses
What is the Functional classification of Symphyses?
Amphiarthroses
Which Functional classification of joint is this: - Slightly mobile joints - Can be fibrous or cartilaginous joints
Amphiarthroses
What is Synchondroses?
An almost immovable joint between bones bound by a layer of cartilage
What is another name for joints?
Articulations
What are Gomphoses joints?
Articulations (joints) of teeth
Where can you find Syndesmoses?
B/w the Radius and Ulna or b/w the Tibia and Fibula.
Where can you find Suture?
B/w the skull bones
What does "Inter-" mean?
Between
What does "-Osseous" mean?
Bones
What does "-chon" mean?
Cartilage
What does "-chon" mean??
Cartilage
Fibrocartilage is associated w/ what type of Structural joint?
Cartilaginous joint
Hyaline cartilage is associated w/ what type of Structural joint?
Cartilaginous joint
Bones joined by cartilage are an example of
Cartilaginous joints
Which Functional classification of joint is this: - Freely mobile joints - All synovial joints
Diarthroses
What type of cartilage joins the bones of Symphyses?
Fibrocartilage
Bones held together by dense connective tissue are an example of
Fibrous joints
What is Synostoses?
Fusing of two bones
What type of cartilage joins the bones of Synchondroses?
Hyaline Cartilage
What does "-itis" mean?
Inflammation
Arthrology is the study of
Joints
Places of contact b/w bones, bones and cartilage, or bones and teeth are called
Joints (articulations)
What are Syndesmoses joints?
Joints bound by interosseous membranes.
Are all fibrous joints Synarthroses?
No. Can be Synarthroses or Amphiarthroses.
Given that the shoulder is a very mobile joint, how stable is it?
Not very stable. More mobility equals less stability.
What is a Symphyses?
Pads of Fibrocartilage b/w articulating bones (joints)
What is the function of a Syndesomes joint?
Provides a pivot for two long bones.
What does "Costo-" mean?
Ribs
How would you describe Suture joints?
Seams in the skull
Skull sutures are an example of an Inverse relationship how?
Skull sutures are immobile, but very stable.
What is the Functional classification for Sutures?
Synarthroses
What is the Functional classification of Synchodroses?
Synarthroses
What is the functional classification of a Gomphoses joint?
Synarthroses
Which Functional classification of joint is this: - Immobile joints - Can be fibrous or cartilaginous joints
Synarthroses
What kind of joints are Diarthroses joints?
Synovial (freely movable) joints
Bones that are joined by ligaments, w/ a fluid-filled joint cavity, separating bone surfaces is an example of
Synovial joints
In a Gomphoses joint, what holds the teeth in place?
Tooth held in place by fibrous periodontal membranes
True or False. Cartilaginous joints are immobile or slightly mobile.
True.
Do Sutures have very long fibers or very short fibers?
Very short fibers
How do you treat Costochondritis?
With Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) Ex: Ibuprofen or Tylenol
What does "Syn-" mean?
Without; as in without movement.
Are all Synovial joints Diarthroses joints?
Yes.
True or False. Cartilaginous joints have a lack of joint cavity.
True.
True or False. Structure of each joint determines its mobility and stability.
True.
True or False. Sutures allow for growth in the skull during childhood.
True.
What kind of edges to Sutures have?
Interlocking, irregular edges
Synchondroses is associated w/ which type of Structural joint?
Cartilaginous joints
True or False. Fibrous joints have no joint cavity.
True.
Skull sutures are an example of what type of relationship?
Inverse relationship
What is the purpose for Interlocking, irregular edges of a Suture?
Increases strength in the skull, and decreases the risk for fracture.
What is Costochonitis?
Inflammation of the cartilage of the ribs or "Costochondral joints"
What are the 3 FUNCTIONAL classes of joints?
- Synarthroses - Amphiarthroses - Diarthroses
True or False. Cartilaginous joints can be either hyaline cartilage or fibrocartilage b/w bones.
True.
True or False. Costochondritis may be mistaken for pain from a Myocardial Infarction (Heart Attack).
True.
True or False. Fibrous joints are connected by dense regular connective tissue.
True.
True or False. Fibrous joints are immobile or only slightly movable.
True.
True or False. Motion ranges from no movement to extensive movement.
True.
True or False. Sutures become ossified Synostoses in older adults.
True.
True or False. Symphyses allow slight mobility.
True.
True or False. Synchodroses are immobile.
True.
True or False. There is an Inverse relationship b/w mobility and stability.
True.
