Introduction
This BIOL251 Human Anatomy & Physiology I w/Lab – Module 4 Exam Review is a
comprehensive study guide designed to help students prepare effectively for their Portage
Learning exams using the LockDown Browser. Covering 90 high-yield questions with answers
and explanations, this review focuses on joint structure, synovial joint types, movements, and
muscular actions.
Module 4 emphasizes understanding arthrology and movement terminology, including flexion,
extension, abduction, adduction, rotation, circumduction, pronation, supination, inversion,
and eversion, as well as applying these concepts to lab exercises and clinical scenarios.
Whether you are studying for a proctored exam or lab practical, this guide provides a concise
yet thorough summary to reinforce critical concepts in human anatomy and physiology.
1. Which type of joint allows no movement?
a) Synovial
b) Cartilaginous
c) Fibrous
d) Diarthrosis
Answer: c) Fibrous – Fibrous joints like sutures are immovable (synarthroses).
2. A joint that is slightly movable is called:
a) Diarthrosis
b) Amphiarthrosis
c) Synarthrosis
d) Synovial
Answer: b) Amphiarthrosis – Found in intervertebral discs and pubic symphysis.
3. What type of joint is the shoulder (glenohumeral joint)?
a) Hinge
b) Ball-and-socket
c) Pivot
d) Saddle
Answer: b) Ball-and-socket – Allows movement in multiple planes.
, 4. Which movement decreases the angle between two bones?
a) Extension
b) Flexion
c) Abduction
d) Adduction
Answer: b) Flexion – Flexion bends a joint, reducing the angle.
5. Pointing the toes upward is called:
a) Plantarflexion
b) Dorsiflexion
c) Pronation
d) Supination
Answer: b) Dorsiflexion – Toes move toward the shin.
6. Moving a limb away from the midline is:
a) Adduction
b) Abduction
c) Circumduction
d) Rotation
Answer: b) Abduction – Abduction moves limb away from body midline.
7. The elbow is an example of which synovial joint?
a) Hinge
b) Ball-and-socket
c) Pivot
d) Condyloid
Answer: a) Hinge – Allows flexion and extension.
8. The neck turning left or right occurs at which joint?
a) Hinge
b) Pivot
c) Saddle
d) Gliding
Answer: b) Pivot – Atlantoaxial joint allows rotational movement.
9. A thumb moving to touch the little finger is called:
a) Opposition
b) Reposition
c) Flexion
d) Extension
Answer: a) Opposition – Unique to the thumb for grasping.
10. Returning the thumb from opposition is:
a) Abduction
b) Adduction
c) Reposition
