question 16

the axial skeleton includes ______.

a the skull, the scapula, and the vertebral column
b the skull, vertebral column, and pelvis
c the skull, vertebral column, and rib cage
d arms, legs, hands, and feet

Explanation:

Define the axial skeleton

The human skeleton is divided into two main parts: the axial skeleton and the appendicular skeleton. The axial skeleton forms the central axis of the body.

Identify axial components

Using the Skull Anatomy and Vertebral Column Anatomy knowledge points
The axial skeleton consists of 80 bones, which include:

• The skull (cranium and facial bones)
• The vertebral column (spine)
• The thoracic cage (ribs and sternum)

Identify appendicular components

The appendicular skeleton consists of the limbs and the girdles that attach them to the axial skeleton. This includes:

• The pectoral girdle (scapula and clavicle)
• The pelvic girdle (pelvis/hip bones)
• The upper and lower limbs (arms, legs, hands, and feet)

Evaluate the given options

• Option A: Includes the scapula, which is part of the appendicular skeleton.
• Option B: Includes the pelvis, which is part of the appendicular skeleton.
• Option C: Includes the skull, vertebral column, and rib cage, all of which are axial.
• Option D: Includes arms, legs, hands, and feet, which are appendicular.

Answer:

• (A) the skull, the scapula, and the vertebral column
• (B) the skull, vertebral column, and pelvis
• (C) the skull, vertebral column, and rib cage (Correct answer)
• (D) arms, legs, hands, and feet
