Question

1. __ the popliteal region is to the patellar region. 17. the axilla is to the sternum. 18. the ventral side of the body is to the dorsal side. 19. the lungs are to the heart. 20. the brachial region is __ to the antebrachial region.

Explanation:

To solve these anatomical position questions, we use directional terms in anatomy:

Question 17

The axilla (armpit) is lateral to the sternum (breastbone). Lateral means farther from the midline of the body. The sternum is on the midline, and the axilla is away from the midline, so "lateral" fits.

Question 18

The ventral (front) side of the body is anterior to the dorsal (back) side. Anterior and ventral are synonymous for the front of the body, while dorsal and posterior are synonymous for the back. So ventral (front) is anterior to dorsal (back).

Question 19

The lungs are lateral to the heart. The heart is near the midline of the thoracic cavity, and the lungs are on either side of the heart (farther from the midline), so "lateral" describes their position relative to the heart.

Question 20

The brachial region (upper arm) is proximal to the antebrachial region (forearm). Proximal means closer to the point of attachment (the shoulder, in this case) or closer to the trunk. The upper arm (brachial) is closer to the shoulder/trunk than the forearm (antebrachial), so "proximal" is correct.

Answer:

s:

1. The axilla is $\boldsymbol{\text{lateral}}$ to the sternum.
2. The ventral side of the body is $\boldsymbol{\text{anterior}}$ to the dorsal side.
3. The lungs are $\boldsymbol{\text{lateral}}$ to the heart.
4. The brachial region is $\boldsymbol{\text{proximal}}$ to the antebrachial region.
