MODULE 4: ARTICULATIONS (JOINTS) – EXAM REVIEW
Module 4 of BIOL251 focuses on articulations (joints) – the structures where
bones meet. Key topics include the classification of joints (structural and
functional), the anatomy of synovial joints, types of joint movements,
and common joint disorders (e.g., arthritis, bursitis, dislocations).
The actual Portage Learning exam typically includes approximately 30 multiple-
choice questions. The summaries available on Stuvia and Docsity contain 70+
practice questions and answers to help you prepare. The exam is administered
via LockDown Browser, which prevents navigation to other websites or
applications during the test.

,PART 1: CLASSIFICATION OF JOINTS
1. What are the three structural classifications of joints?
A. Fibrous, cartilaginous, synovial
B. Sutures, syndesmoses, gomphoses
C. Synarthroses, amphiarthroses, diarthroses
D. Hinge, ball-and-socket, pivot
A
RATIONALE: Joints are structurally classified based on the type of tissue that
binds the bones together and the presence or absence of a joint cavity. The three
structural classes are fibrous (bones joined by dense connective tissue),
cartilaginous (bones joined by cartilage), and synovial (bones separated by a fluid-
filled joint cavity).
2. Which functional classification of joints allows for the greatest range of
motion?
A. Synarthrosis
B. Amphiarthrosis
C. Diarthrosis
D. Syndesmosis
C
RATIONALE: Diarthroses are freely movable joints (synovial joints) that allow for
the greatest range of motion. Synarthroses are immovable joints, and
amphiarthroses are slightly movable joints.
3. A suture between the bones of the skull is an example of which type of joint?
A. Synovial joint
B. Cartilaginous joint
,C. Fibrous joint
D. Amphiarthrosis
C
RATIONALE: Sutures are fibrous joints found only in the skull. The bones are
tightly connected by dense fibrous connective tissue, allowing for little to no
movement (synarthrosis).
4. The pubic symphysis is classified as which type of joint?
A. Fibrous joint
B. Cartilaginous joint (symphysis)
C. Synovial joint
D. Gomphosis
B
RATIONALE: The pubic symphysis is a cartilaginous joint (specifically a
symphysis) where the bones are connected by fibrocartilage. It allows for slight
movement (amphiarthrosis) and provides stability during weight-bearing activities.
5. Which structural joint type is characterized by the presence of a joint cavity
filled with synovial fluid?
A. Fibrous
B. Cartilaginous
C. Synovial
D. Amphiarthrosis
C
RATIONALE: Synovial joints are the only structural class that possesses a
synovial (joint) cavity filled with synovial fluid. This fluid lubricates the joint, reduces
friction, and provides nourishment to the articular cartilage.
6. A gomphosis (the articulation between a tooth and its socket) is an example
of which type of joint?
, A. Synovial joint
B. Fibrous joint
C. Cartilaginous joint
D. Diarthrosis
B
RATIONALE: A gomphosis is a fibrous joint where a cone-shaped peg fits into a
socket (e.g., tooth in alveolar bone). It is held in place by the periodontal ligament
and allows for no movement (synarthrosis).
7. Which of the following is NOT a functional classification of joints?
A. Synarthrosis
B. Amphiarthrosis
C. Diarthrosis
D. Symphysis
D
RATIONALE: Symphysis is a type of cartilaginous joint (structural classification),
not a functional classification. The three functional classifications are synarthrosis
(immovable), amphiarthrosis (slightly movable), and diarthrosis (freely movable).
8. Which structural joint type is most common in the appendicular skeleton?
A. Fibrous
B. Cartilaginous
C. Synovial
D. Sutural
C
RATIONALE: Synovial joints are the most common type of joint in the
appendicular skeleton (limbs). They allow for the free movement necessary for
locomotion and manipulation of the environment.
