CHAMBERLAIN UNIVERSITY BIOS 251 WEEK 8
FINAL EXAM PRACTICE TEST (2025/2026 UPDATED
CURRICULUM)
INTRODUCTION
This comprehensive practice examination has been designed to prepare Chamberlain University
nursing and health sciences students for the BIOS 251 Week 8 Final Examination in Human
Anatomy & Physiology I with Lab. Based on the 2025/2026 course curriculum, lecture materials,
and laboratory practicum objectives, this 150-question assessment covers all major content
domains including the skeletal system, integumentary system, tissues and membranes, cell
biology, anatomical terminology, bone formation and healing, and the muscular system. This
practice test serves as an essential study tool for mastering the foundational anatomical and
physiological concepts required for success in subsequent nursing coursework and clinical
practice.
DOMAIN 1: SKELETAL SYSTEM & JOINTS (Questions 1-35)
Question 1: The functional classification of joints includes which of the following categories?
A. Fibrous, cartilaginous, synovial
B. Synarthroses, amphiarthroses, diarthroses
C. Hinge, pivot, ball-and-socket
D. Sutures, syndesmoses, gomphoses
Answer: B
Rationale: Functional classification of joints is based on the amount of movement allowed:
synarthroses (immovable), amphiarthroses (slightly movable), and diarthroses (freely movable).
Structural classification (fibrous, cartilaginous, synovial) is based on tissue type and presence of
joint space.
Question 2: Which cervical vertebra is known as the "axis" and allows for head rotation?
A. C1
B. C2
C. C3
D. C7
,Answer: B
Rationale: The axis (C2) is the second cervical vertebra and features the odontoid process (dens)
that allows the atlas (C1) to rotate around it, enabling head rotation from side to side.
Question 3: Which joint is classified as a syndesmosis?
A. Suture between skull bones
B. Distal tibiofibular joint
C. Epiphyseal plate
D. Tooth in alveolar socket
Answer: B
Rationale: A syndesmosis is a fibrous joint where bones are connected by ligaments, such as the
distal tibiofibular joint. Sutures are also fibrous joints, but they are classified separately as
synarthroses with minimal connective tissue.
Question 4: The only movable bone of the skull is the:
A. Maxilla
B. Zygomatic bone
C. Mandible
D. Temporal bone
Answer: C
Rationale: The mandible (lower jaw bone) is the only freely movable bone of the skull,
articulating with the temporal bones at the temporomandibular joints to allow speaking,
chewing, and facial expressions.
Question 5: Which bone forms the posterior base of the skull and contains the foramen
magnum?
A. Frontal bone
B. Parietal bone
C. Occipital bone
D. Temporal bone
Answer: C
,Rationale: The occipital bone forms the posterior and inferior portions of the cranium and
contains the foramen magnum, the large opening through which the spinal cord connects to the
brainstem.
Question 6: The sagittal suture is located between which two bones?
A. Frontal and parietal bones
B. Two parietal bones
C. Parietal and temporal bones
D. Occipital and parietal bones
Answer: B
Rationale: The sagittal suture is the fibrous joint that connects the two parietal bones along the
midline of the skull, running from the coronal suture anteriorly to the lambdoid suture
posteriorly.
Question 7: Which carpal bone is most commonly fractured?
A. Scaphoid
B. Lunate
C. Triquetrum
D. Pisiform
Answer: A
Rationale: The scaphoid is the most commonly fractured carpal bone due to its position in the
proximal row and its role in transmitting forces from the hand to the forearm during falls on an
outstretched hand.
Question 8: The "sit bone" that bears weight when sitting is part of which pelvic bone?
A. Ilium
B. Ischium
C. Pubis
D. Sacrum
Answer: B
, Rationale: The ischial tuberosity, commonly called the "sit bone," is the posterior-inferior
portion of the ischium that bears body weight when sitting and serves as the origin for the
hamstring muscles.
Question 9: Which tarsal bone forms the heel of the foot?
A. Talus
B. Navicular
C. Calcaneus
D. Cuboid
Answer: C
Rationale: The calcaneus is the largest tarsal bone and forms the heel. It articulates with the
talus superiorly and transmits body weight from the talus to the ground during standing and
walking.
Question 10: The pubic symphysis is classified as which type of joint?
A. Fibrous joint
B. Synovial joint
C. Synchondrosis
D. Symphysis (cartilaginous joint)
Answer: D
Rationale: The pubic symphysis is a cartilaginous joint (symphysis type) where the two pubic
bones are joined by fibrocartilage, allowing slight movement that facilitates childbirth.
Question 11: Which bone is the longest in the human body?
A. Humerus
B. Femur
C. Tibia
D. Fibula
Answer: B
