Question

Which specific anatomical features are found in the upper axial region?

a. head
b. arms
c. abdomen
d. neck

Answer 1

The specific anatomical features found in the upper axial region include:

a. Head

d. Neck

So, the correct options are a and d. The head is located at the top of the axial region, and the neck connects the head to the rest of the body. The arms and abdomen are considered part of the appendicular region.

Answer 2

The upper axial region includes specifically the head and neck, which are part of the axial skeleton. The heart could be at risk due to thoracic cage abnormalities. The right ventricle sends blood to the lungs and the cervical region has the greatest rotation motion.

Step-by-step explanation:

The specific anatomical features found in the upper axial region include the head and neck. These are crucial parts of the axial skeleton, which forms the vertical central axis of the body, supporting the head, neck, back, and chest. This includes the skull, vertebral column, and thoracic cage. The thoracic cage specifically protects vital organs such as the heart and also serves as an attachment site for muscles that are essential for respiration and upper limb movement.

Abnormalities in the thoracic cage could greatly affect the organs it protects, such as the heart, which would be most at risk. The right ventricle of the heart sends blood specifically to the lungs for oxygenation. The axial skeleton includes the thoracic cage and vertebral column, but does not include the pectoral or pelvic girdles, which are part of the appendicular skeleton. Additionally, the vertebral column region with the greatest range of motion for rotation is the cervical region.
