Mastering A&P Chapter 8 Flashcards

Functional classification of joints is based on:

Which of the following does not represent a structural classification of joints?

Which of the following refers to a joint that is immovable?

Which one is correctly paired?

Using a structural classification, what type of joint is the epiphyseal plate?

Most joints of the body are classified as _______ joints.

Which of the following is not a factor that stabilizes joints?

Extension is an example of a(n) ______ movement.

The shoulder and hip are examples of:

Synovial joints are classified into six main categories based on:

Which inflammatory disease of joints is caused by the bites of ticks that live on mice and deer?

Synovial fluid does not:

The main contributor to hip joint stability is:

Articulations permitting only slight degrees of movement are ________.

Synarthrotic joints ________.

On the basis of structural classification, which joint is fibrous connective tissue?

Fibrous joints are classified as ________.

The structural classification of joints is based on the composition of the binding material and the presence or absence of a joint cavity.

Articular cartilage found at the ends of the long bones serves to ________.

A joint united by dense fibrocartilaginous tissue that usually permits a slight degree of movement is a ________.

Functional Classification of Joints

Functional classification is based on the amount of movement allowed by the joint.

Structural Classification of Joints

Diarthroses do not represent a structural classification; they signify a functional category.

Types of Joints

Synarthrosis refers to an immovable joint.
Synchondroses involve a plate of hyaline cartilage uniting bones, correctly paired in joint classification.
Epiphyseal plates are classified as cartilaginous joints, crucial during growth.

Joint Prevalence

Most joints in the body are synovial joints, supporting a wide range of movements.

Joint Stability Factors

Joint stability is influenced by the shapes of articulating surfaces, muscle tone, and the number and position of ligaments; synovial fluid does not stabilize joints.

Joint Movements

Extension is categorized as an angular movement.

Joint Types and Examples

Ball-and-socket joints, such as shoulder and hip, allow multi-directional movement.
Synovial joints are classified into six main categories based on allowed movements.

Lyme disease, caused by tick bites, is an inflammatory joint disease.

Synovial Fluid Functions

Synovial fluid lubricates joints and nourishes cartilage but does not strengthen synovial joints.

Hip Joint Stability

The deep socket of the hip joint significantly contributes to its stability.

Degrees of Joint Movement

Amphiarthroses allow slight degrees of movement.

Synarthrotic Joints

Synarthrotic joints permit virtually no movement; found at junctions of growing bones.

Joint Connections

Syndesmosis is a joint connected by dense fibrocartilaginous tissue allowing slight movement.
Fibrous joints include sutures, syndesmoses, and gomphoses.

Structural Composition

The structural classification of joints is determined by the binding material's composition and the joint cavity's presence or absence.

Articular Cartilage Function

Articular cartilage at the ends of long bones provides a smooth surface at synovial joints.

Symphysis Joint Definition

A symphysis is a joint united by fibrocartilaginous tissue, allowing limited movement.

Test your knowledge on the functional and structural classification of joints with these practice questions. This quiz covers key concepts from Chapter 8 of Anatomy and Physiology, helping reinforce your understanding of joint classifications.
