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.
