Section 1: Joints and Articulations (Chapter 8) - Questions 1-35
Q1: A suture, such as those found between the bones of the skull, is structurally classified as
which type of joint?
• A. Cartilaginous
, • B. Synovial
• C. [CORRECT] Fibrous
• D. Symphysis
Rationale:
• Sutures are fibrous joints where bones are united by dense fibrous connective tissue
• Functionally classified as synarthrotic (immovable)
• Examples include the coronal, sagittal, and lambdoid sutures of the skull
Q2: The joint between the tooth and its bony socket (the alveolar process) is called a:
• A. Symphysis
• B. [CORRECT] Gomphosis
• C. Synchondrosis
• D. Condyloid joint
Rationale:
• A gomphosis is a specialized fibrous joint that anchors a tooth to its socket via the
periodontal ligament
• Functionally classified as a synarthrosis (immovable)
• The only example of this joint type in the human body
Q3: Which of the following joints is functionally classified as amphiarthrotic (slightly movable)
and structurally as cartilaginous?
• A. Suture
• B. Gomphosis
• C. [CORRECT] Symphysis pubis
• D. Ball-and-socket joint
Rationale:
• The symphysis pubis is a cartilaginous joint joined by fibrocartilage, allowing slight
movement (amphiarthrotic)
• Other examples include intervertebral discs
• Amphiarthrotic joints provide strength while allowing limited flexibility
Q4: The epiphyseal (growth) plate in a growing child is an example of which type of joint?
• A. [CORRECT] Synchondrosis
• B. Symphysis
, • C. Suture
• D. Hinge joint
Rationale:
• A synchondrosis is a cartilaginous joint where bones are joined by hyaline cartilage
• The epiphyseal plate is a temporary synchondrosis that ossifies (becomes bone) when
growth stops
• Functionally classified as synarthrotic (immovable)
Q5: Which joint classification allows for the greatest range of motion and includes most joints of
the appendicular skeleton?
• A. Fibrous joints
• B. Cartilaginous joints
• C. [CORRECT] Synovial joints
• D. Amphiarthrotic joints
Rationale:
• Synovial joints are freely movable (diarthrotic) and include most limb joints such as the
shoulder, hip, elbow, and knee
• These joints contain a fluid-filled cavity that reduces friction between articulating bones
• Characterized by the presence of articular cartilage and a joint capsule
Q6: A ball-and-socket joint, such as the hip or shoulder, permits which types of movement?
• A. Flexion and extension only
• B. Rotation only
• C. [CORRECT] Multiaxial movement including flexion, extension, abduction, adduction, and
rotation
• D. Gliding movement only
Rationale:
• Ball-and-socket joints allow multiaxial movement in all planes and axes
• Movements include flexion, extension, abduction, adduction, circumduction, and rotation
• These are the most mobile type of synovial joint, providing maximum range of motion
Q7: Which type of synovial joint permits movement primarily in one plane, like the elbow or
knee?
• A. Pivot joint
, • B. [CORRECT] Hinge joint
• C. Condyloid joint
• D. Saddle joint
Rationale:
• Hinge joints allow movement primarily in one plane (uniaxial), permitting flexion and
extension
• Examples include the elbow, knee, and interphalangeal joints
• These joints function similarly to a door hinge, allowing opening and closing motions
Q8: The atlantoaxial joint between the first and second cervical vertebrae (C1 and C2), which
allows rotation of the head, is an example of a:
• A. Hinge joint
• B. Ball-and-socket joint
• C. [CORRECT] Pivot joint
• D. Gliding joint
Rationale:
• Pivot joints allow rotation around a central axis (uniaxial movement)
• The atlantoaxial joint allows the head to rotate from side to side ("no" motion)
• Another example is the radioulnar joint at the elbow
Q9: Joints are structurally classified into three main categories. What are they?
• A. Synarthrosis, amphiarthrosis, diarthrosis
• B. [CORRECT] Fibrous, cartilaginous, synovial
• C. Hinge, pivot, ball-and-socket
• D. Suture, symphysis, gomphosis
Rationale:
• Joints are structurally classified based on the presence or absence of a joint cavity and the
type of connective tissue binding bones together
• Fibrous (no cavity, fibrous tissue), Cartilaginous (no cavity, cartilage), Synovial (fluid-
filled cavity present)
Q10: Joints are functionally classified into three main categories. What are they?
• A. Fibrous, cartilaginous, synovial
• B. Hinge, pivot, ball-and-socket
• C. [CORRECT] Synarthrosis, amphiarthrosis, diarthrosis
