Exercise B Practice: Regional and Directional Terms

The task involves filling in the blanks with the correct anatomical directional terminology. Below is the solution with explanations for each question.

---

#### 1. The mouth is ________ to the nose/nasus and ________ to the mentis.
- Explanation:
- The mouth is located below the nose, so it is inferior to the nose.
- The mentis refers to the chin, which is below the mouth, so the mouth is superior to the mentis.
- Answer:
- The mouth is inferior to the nose/nasus and superior to the mentis.

#### 2. The olecranon is ________ or ________ to the pollex and ________ to the antecubital region (all on the same side).
- Explanation:
- The olecranon is the bony prominence of the elbow.
- The pollex is the thumb. The olecranon is farther away from the thumb than the wrist, so it is distal or dorsal to the pollex.
- The antecubital region is the area in front of the elbow, so the olecranon is posterior to the antecubital region.
- Answer:
- The olecranon is distal or dorsal to the pollex and posterior to the antecubital region.

#### 3. The right nipple is ________ to the right clavicle, ________ to the right axillary region, ________ to the sternum and ________ to the right lung.
- Explanation:
- The right nipple is closer to the right clavicle than the sternum, so it is inferior to the right clavicle.
- The right nipple is closer to the right axillary region than the sternum, so it is medial to the right axillary region.
- The right nipple is closer to the sternum than the ribs, so it is lateral to the sternum.
- The right nipple is closer to the right lung than the left lung, so it is medial to the right lung.
- Answer:
- The right nipple is inferior to the right clavicle, medial to the right axillary region, lateral to the sternum, and medial to the right lung.

#### 4. Along the digestive tract, the stomach is ________ to the mouth and ________ to the small intestine.
- Explanation:
- The stomach is located after the mouth in the digestive tract, so it is distal to the mouth.
- The stomach is located before the small intestine in the digestive tract, so it is proximal to the small intestine.
- Answer:
- Along the digestive tract, the stomach is distal to the mouth and proximal to the small intestine.

---

#### 5. Along the digestive tract, the small intestine is ________ to the stomach and ________ large intestine.
- Explanation:
- The small intestine is located after the stomach in the digestive tract, so it is distal to the stomach.
- The small intestine is located before the large intestine in the digestive tract, so it is proximal to the large intestine.
- Answer:
- Along the digestive tract, the small intestine is distal to the stomach and proximal to the large intestine.

#### 6. The sternum is ________ to the umbilicus.
- Explanation:
- The sternum is located above the umbilicus (navel), so it is superior to the umbilicus.
- Answer:
- The sternum is superior to the umbilicus.

---

#### 7. The pollex is ________ to the palm and ________ to the carpus.
- Explanation:
- The pollex (thumb) is located on the lateral side of the hand relative to the palm, so it is lateral to the palm.
- The pollex is located distally to the carpus (wrist), so it is distal to the carpus.
- Answer:
- The pollex is lateral to the palm and distal to the carpus.

#### 8. Your stomach is ________ to your skin.
- Explanation:
- The stomach is located deep within the abdominal cavity, beneath the skin, so it is deep to the skin.
- Answer:
- Your stomach is deep to your skin.

---

#### 9. Your ________ is contralateral to your left arm.
- Explanation:
- Contralateral means "on the opposite side." The structure contralateral to the left arm is the right arm.
- Answer:
- Your right arm is contralateral to your left arm.

---

#### 10. Your right knee is ________ to your thorax.
- Explanation:
- The right knee is located below the thorax, so it is inferior to the thorax.
- Answer:
- Your right knee is inferior to your thorax.

---

#### 11. Write two comparisons using the terms distal and proximal.
- Explanation:
- Distal means "farther away from the origin or center," while proximal means "closer to the origin or center."
- Example 1: The fingers are distal to the wrist, and the wrist is proximal to the fingers.
- Example 2: The toes are distal to the ankle, and the ankle is proximal to the toes.
- Answer:
- The fingers are distal to the wrist, and the wrist is proximal to the fingers.
- The toes are distal to the ankle, and the ankle is proximal to the toes.

Final Answer:

1. inferior, superior
2. distal/dorsal, posterior
3. inferior, medial, lateral, medial
4. distal, proximal
5. distal, proximal
6. superior
7. lateral, distal
8. deep
9. right arm
10. inferior
11.
- The fingers are distal to the wrist, and the wrist is proximal to the fingers.
