if an incision cuts the brain into superior and inferior parts, the section is a __14__ section; but if the brain is cut so that anterior and posterior portions result, the section is a __15__ section. you are told to cut a dissection animal along two planes so that the lungs are observable in both sections. the two sections that meet this requirement are the __16__ and __17__ sections.

Accepted Answer

### Question 2 (Filling the Blanks)
#### 1.
# Answer:
anterior
# Brief Explanations:
In anatomical position, umbilicus and knees are on the front (anterior) body surface.

#### 2.
# Answer:
posterior
# Brief Explanations:
Buttocks and shoulder blades are on the back (posterior) body surface.

#### 3.
# Answer:
inferior
# Brief Explanations:
Soles of feet are the lowest (inferior) part of the body.

#### 4.
# Answer:
lateral; lateral
# Brief Explanations:
Ears are away from the midline (lateral) and lateral to shoulders (also away from midline relative to shoulders).

#### 5.
# Answer:
medial
# Brief Explanations:
Ears are closer to midline (medial) relative to nose? No, wait, ears are lateral to nose. Wait, correction: Ears are lateral to nose? Wait, no, the question is "the ears are __4__ and __4__ to the shoulders and __5__ to the nose". So ears are lateral to shoulders? No, shoulders are more lateral. Wait, ears are medial to shoulders? No, shoulders are at the sides, ears are on the head, so ears are medial to shoulders? Wait, no, lateral means away from midline. Shoulders are more lateral than ears? No, ears are on the head, shoulders are on the arms. Wait, maybe I messed up. Let's re - think: Ears are lateral to the nose (since nose is midline, ears are on the sides), and ears are medial to the shoulders (since shoulders are more towards the sides than ears). Wait, the key terms: medial is towards midline, lateral is away. So ears are lateral to nose (away from midline) and medial to shoulders (towards midline relative to shoulders). Wait, the first two blanks (4) are for relation to shoulders. So ears are medial to shoulders? No, shoulders are at the ends of the clavicles, ears are on the head. So ears are medial to shoulders (since shoulders are more lateral). And ears are lateral to nose (since nose is midline). So 4: medial (wait, no, maybe I got it wrong). Wait, the key has lateral, medial. Let's check standard anatomy: Ears are lateral to the nose (because nose is in the midline, ears are on the sides), and ears are medial to the shoulders (because shoulders are more laterally placed than ears). So 4: medial? No, that can't be. Wait, maybe the first two 4s are lateral. Wait, maybe the question is "the ears are __4__ and __4__ to the shoulders" – no, the original text: "the ears are __4__ and __4__ to the shoulders and __5__ to the nose". So two blanks for relation to shoulders, one for nose. So ears are lateral to shoulders? No, shoulders are more lateral. Wait, I think I made a mistake. Let's recall: In anatomical terms, lateral means farther from the midline, medial means closer. So the ears: relative to the shoulders (which are at the sides of the body), the ears are medial (closer to midline) than the shoulders. And relative to the nose (midline), the ears are lateral (farther from midline). So 4: medial (twice? No, the key has lateral, medial. Wait, maybe the first two 4s are lateral. Wait, maybe the question is mis - phrased. Alternatively, maybe the ears are lateral to the shoulders? No, that doesn't make sense. I think I need to correct: Ears are lateral to the nose (so 5 is medial? No, nose is midline, ears are lateral to nose. Wait, I'm confused. Let's look at the key terms again: anterior, inferior, posterior, superior, distal, lateral, proximal, transverse, frontal, medial, sagittal. Let's do each blank step by step.

1. Umbilicus and knees: anterior (front) – correct.
2. Buttocks and shoulder blades: posterior (back) – correct.
3. Soles of feet: inferior (below) – correct.
4. Ears relative to shoulders: medial (because shoulders are more lateral) – so two blanks, both medial? No, the key has lateral. Wait, maybe the ears are lateral to the shoulders? No, shoulders are at the ends of the clavicles, ears are on the head. So ears are medial to shoulders. So 4: medial, medial.
5. Ears relative to nose: lateral (because nose is midline, ears are on the sides) – so 5: lateral. Wait, that makes sense. So 4: medial, medial; 5: lateral.

#### 6.
# Answer:
anterior
# Brief Explanations:
Breastbone (sternum) is in front (anterior) of the vertebral column (spine).

#### 7.
# Answer:
inferior
# Brief Explanations:
Breastbone is below (inferior) to the shoulders.

#### 8.
# Answer:
distal
# Brief Explanations:
Elbow is farther (distal) from the shoulder? No, wait, proximal is closer, distal is farther. Elbow is closer to shoulder than fingers, so elbow is proximal to shoulder? Wait, no: proximal means closer to the point of attachment (shoulder is the attachment for the arm), so elbow is proximal to shoulder? No, that's wrong. Wait, the arm: shoulder is the origin, elbow is between shoulder and fingers. So elbow is distal to shoulder? No, proximal is closer to the trunk (shoulder is part of the trunk - arm connection), so elbow is distal to shoulder? No, I'm mixing up. Proximal: closer to the point of attachment (the body trunk), distal: farther. So elbow is distal to shoulder? No, shoulder is the attachment, so elbow is distal to shoulder? Wait, no, the shoulder is the joint, the arm starts at the shoulder. So the elbow is distal to the shoulder (farther from the trunk) and proximal to the fingers (closer to the trunk than fingers). So 8: distal? No, wait, the question is "The elbow is __8__ to the shoulder but __9__ to the fingers". So elbow to shoulder: distal (farther from trunk) or proximal (closer)? Wait, shoulder is the attachment, so the elbow is distal to the shoulder (because it's farther from the trunk than the shoulder). And proximal to the fingers (closer to the trunk than the fingers). So 8: distal, 9: proximal.

#### 9.
# Answer:
proximal
# Brief Explanations:
Elbow is closer (proximal) to the trunk than fingers.

#### 10.
# Answer:
superior
# Brief Explanations:
Thoracic cavity is above (superior) to the abdominopelvic cavity.

#### 11.
# Answer:
anterior
# Brief Explanations:
Thoracic cavity is in front (anterior) of the spinal cavity.

#### 12.
# Answer:
anterior
# Brief Explanations:
In humans, ventral (front) is also called anterior.

#### 13.
# Answer:
inferior
# Brief Explanations:
In quadrupeds, ventral (belly side) is the inferior (lower) surface.

#### 14.
# Answer:
transverse
# Brief Explanations:
Transverse section cuts into superior and inferior parts.

#### 15.
# Answer:
frontal
# Brief Explanations:
Frontal (coronal) section cuts into anterior and posterior parts.

#### 16.
# Answer:
sagittal
# Brief Explanations:
Sagittal section and frontal (or transverse) can show lungs. Wait, to see lungs, sagittal and frontal (coronal) or transverse? Wait, lungs are in the thoracic cavity. A sagittal section (dividing left and right) and a frontal (coronal) section (dividing anterior and posterior) would both show lungs. Or sagittal and transverse? Wait, the question is "cut a dissection animal along two planes so that the lungs are observable in both sections". The two planes: sagittal and frontal (coronal) or sagittal and transverse? Wait, transverse section cuts into superior and inferior, but lungs are in the thoracic cavity, so transverse would show lungs as a cross - section. Sagittal would show left and right lung parts. Frontal (coronal) would show anterior and posterior lung parts. So the two sections could be sagittal and frontal (coronal) or sagittal and transverse. But from the key, we have sagittal, frontal, transverse. So 16: sagittal, 17: frontal (or transverse). Wait, the key has frontal, sagittal, transverse. Let's check: If we cut along sagittal (divides left - right) and frontal (divides anterior - posterior), both will show the lungs. So 16: sagittal, 17: frontal.

#### 17.
# Answer:
frontal
# Brief Explanations:
As explained above, sagittal and frontal sections both show lungs.

### Question 3
# Answer:
The lateral femoral region is the outer (lateral) part of the thigh (femoral region). So you should uncover the outer part of your thigh.
# Brief Explanations:
"Lateral" means away from the midline, and "femoral region" refers to the thigh. So the lateral femoral region is the outer side of the thigh.
