Complete Solutions Questions for Anatomy &
Physiology Lab Practical 2

SECTION 1: AXIAL SKELETON


Question 1
The axial skeleton consists of:
A. The bones of the limbs and limb girdles
B. The skull, rib cage, and vertebral column
C. The hands and feet only
D. The pelvis and shoulder girdle
Answer: B
Rationale: The axial skeleton consists of the skull, rib cage (thoracic cage), and
vertebral column. It forms the central axis of the body and protects vital organs
such as the brain, heart, and lungs.


Question 2
The appendicular skeleton consists of:
A. The skull, rib cage, and vertebral column
B. The bones of the limbs and limb girdles that are attached to the axial skeleton
C. The hands and feet only
D. The vertebrae and ribs
Answer: B
Rationale: The appendicular skeleton consists of the bones of the limbs (arms and
legs) and the limb girdles (pectoral and pelvic girdles) that are attached to the axial
skeleton.

,Question 3
How many bones are in the adult human axial skeleton?
A. 80
B. 126
C. 206
D. 100
Answer: A
Rationale: The adult human axial skeleton consists of 80 bones. The appendicular
skeleton consists of 126 bones, for a total of 206 bones in the adult body.


Question 4
How many bones are in the adult human appendicular skeleton?
A. 80
B. 126
C. 206
D. 100
Answer: B
Rationale: The adult human appendicular skeleton consists of 126 bones. The
axial skeleton consists of 80 bones, for a total of 206 bones in the adult body.


Question 5
The skull is part of which division of the skeleton?
A. Appendicular skeleton
B. Axial skeleton
C. Both axial and appendicular
D. Neither
Answer: B
Rationale: The skull is part of the axial skeleton. The axial skeleton includes the
skull, vertebral column, and thoracic cage.

,Question 6
The vertebral column is part of which division of the skeleton?
A. Appendicular skeleton
B. Axial skeleton
C. Both axial and appendicular
D. Neither
Answer: B
Rationale: The vertebral column is part of the axial skeleton. It forms the central
axis of the body and protects the spinal cord.


Question 7
The ribs are part of which division of the skeleton?
A. Appendicular skeleton
B. Axial skeleton
C. Both axial and appendicular
D. Neither
Answer: B
Rationale: The ribs are part of the axial skeleton. They form the thoracic cage
along with the sternum and thoracic vertebrae.


Question 8
The sternum (breastbone) is part of which division of the skeleton?
A. Appendicular skeleton
B. Axial skeleton
C. Both axial and appendicular
D. Neither
Answer: B

, Rationale: The sternum is part of the axial skeleton. It is the flat bone located in
the center of the chest that forms the anterior part of the thoracic cage.


Question 9
The shoulder girdle (pectoral girdle) is part of which division of the skeleton?
A. Appendicular skeleton
B. Axial skeleton
C. Both axial and appendicular
D. Neither
Answer: A
Rationale: The shoulder girdle (pectoral girdle) is part of the appendicular
skeleton. It connects the upper limbs to the axial skeleton.


Question 10
The pelvis (hip bones) is part of which division of the skeleton?
A. Appendicular skeleton
B. Axial skeleton
C. Both axial and appendicular
D. Neither
Answer: A
Rationale: The pelvis (hip bones) is part of the appendicular skeleton. It connects
the lower limbs to the axial skeleton.


SECTION 2: BONE CLASSIFICATION


Question 11
Long bones are described as:
A. Shaped roughly as a cube and contains mostly spongy bone
B. Hard, dense bones that provide strength, structure, and mobility
