Solved DIRECTIONAL TERMINOLOGY WORKSHEET 1. The finger is 2 ... - Free Printable

It looks like you've uploaded a Directional Terminology Worksheet used in anatomy and physiology to teach anatomical position and directional terms. The worksheet contains 45 questions asking students to fill in the blanks with correct anatomical directional terms (e.g., superior, inferior, anterior, posterior, medial, lateral, proximal, distal, superficial, deep, etc.).

You’ve already filled in some answers — many of which are correct — but there are several missing or incomplete ones.

Let me go through each question, provide the correct answer, and explain why it's correct based on standard anatomical terminology. I’ll also correct any errors.

Anatomical Directional Terms Reference:

- Superior: Above
- Inferior: Below
- Anterior (ventral): Front
- Posterior (dorsal): Back
- Medial: Toward the midline
- Lateral: Away from the midline
- Proximal: Closer to the point of attachment (e.g., trunk)
- Distal: Farther from the point of attachment
- Superficial: Closer to the surface
- Deep: Deeper within the body
- Ipsilateral: Same side
- Contralateral: Opposite side
- Palmar: Palm of hand
- Plantar: Sole of foot

Now let’s solve the entire worksheet:

---

1. The finger is ___ to the palm.
→ Distal
*Explanation:* Fingers are farther from the trunk than the palm.

2. The heart is ___ to the sternum.
→ Deep
*Explanation:* The heart lies behind the sternum (breastbone), so it's deeper.

3. The head is ___ to the neck.
→ Superior
*Explanation:* Head is above the neck.

4. The thumb is ___ to the fingers.
→ Lateral
*Explanation:* The thumb is on the outer side of the hand compared to the other fingers.

5. The arm is ___ to the trunk.
→ Lateral
*Explanation:* Arms are on the sides of the trunk.

6. The foot is ___ to the knee.
→ Distal
*Explanation:* Foot is farther from the trunk than the knee.

7. The skin is ___ to muscle.
→ Superficial
*Explanation:* Skin is on top of muscles.

8. The brain is ___ to the cranium.
→ Deep
*Explanation:* Brain is inside the skull (cranium), so it's deeper.

9. The wrist is ___ to the hand.
→ Proximal
*Explanation:* Wrist is closer to the forearm/trunk than the hand.

10. The sternum is ___ to the spine.
→ Anterior
*Explanation:* Sternum is in front of the spine.

11. The brain is ___ to the spinal cord.
→ Superior
*Explanation:* Brain is above the spinal cord.

12. The lungs are ___ to the stomach.
→ Superior
*Explanation:* Lungs are above the stomach.

13. The spine is ___ to the chest.
→ Posterior
*Explanation:* Spine is behind the chest.

14. The chest is on the ___ surface.
→ Anterior
*Explanation:* Chest is the front part of the body.

15. The hip is on the ___ surface.
→ Lateral
*Wait — this is ambiguous.*
Actually, "surface" likely refers to anterior/posterior/lateral/medial, not just "lateral." But hips are on the lateral side of the trunk? Not exactly.
Better interpretation: The hip is on the inferior surface relative to the abdomen? Or perhaps they mean lateral because it's on the side.
But the correct term here might be superior? No — that doesn't fit.
Let’s reconsider: The hip region is on the lateral side of the lower trunk, but more precisely, it's posterior and lateral.
However, commonly, the hip is described as being on the lateral surface of the trunk.
So: Lateral is acceptable.
✔ Answer: Lateral

16. The buttocks is on the ___ surface.
→ Posterior
*Explanation:* Buttocks are on the back side of the body.

17. The eyebrows are ___ to the nose.
→ Superior
*Explanation:* Eyebrows are above the nose.

→ Medial
*Explanation:* Breast is toward the midline compared to the armpit (which is lateral).

20. The arm is ___ to the forearm.
→ Proximal
*Explanation:* Arm (humerus) is closer to the shoulder/trunk than the forearm.

*Already correctly filled.*

22. The sternum is ___ to the heart.
→ Anterior
*Explanation:* Sternum is in front of the heart.

23. Muscles are ___ to the skin.
→ Deep
*Explanation:* Muscles lie beneath the skin.

24. The forehead is ___ to the nose.
→ Superior
*Explanation:* Forehead is above the nose.

→ Proximal
*Explanation:* Knee is closer to the trunk than the foot.

38. The umbilicus is ___ to the spine.
→ Anterior
*Explanation:* Umbilicus is in front of the spine.

39. The thorax is ___ to the abdomen.
→ Superior
*Explanation:* Thorax is above the abdomen.

40. The fingernail is ___ & ___ to the fingertip.
→ Distal and Superior
*Wait — directionally, fingernail is on the tip, so it's distal, but “superior” is incorrect here.*
Actually, in anatomical terms, the nail is distal to the fingertip? No — the nail is on the fingertip.
But the fingertip is the end, so the nail is distal and superior only if we consider orientation.
Better: The fingernail is distal to the base of the finger, and superior when considering the hand’s orientation (top).
But typically: Distal and Anterior? Not quite.
Actually, the fingernail is distal to the phalanges and dorsal (back side) of the fingertip.
But the question says “to the fingertip.” So:
- The fingernail is on the fingertip.
- But if comparing positions, it's distal and dorsal?
However, most textbooks say: The fingernail is distal and dorsal to the fingertip — but that’s confusing.
Actually, the fingernail is at the distal end of the fingertip.
So better: Distal and Dorsal
But since “dorsal” isn’t listed, maybe the expected answer is:
→ Distal and Superior? That’s not accurate.
Alternatively, perhaps they mean:
→ Distal and Anterior? No — nails are on the dorsal side.
Wait — in the hand, the palmar side is anterior, dorsal is posterior.
So fingernails are on the dorsal side of the fingertip.
So: Distal and Dorsal
✔ Answer: Distal and Dorsal

41. The third metacarpal is ___ to the second and forth metacarpals.
→ Medial
*Wait — metacarpals are numbered 1–5 from thumb to little finger.*
Third metacarpal (middle finger) is between second (index) and fourth (ring).
So it is medial to both? No — it’s central, but relative to second and fourth:
- Second metacarpal is lateral to third
- Fourth is medial to third
But the question says: “third metacarpal is ___ to the second and forth”
So: Third is medial to second and lateral to fourth?
But the blank is one word.
So perhaps: Intermediate? But that’s not a standard directional term.
Standard terms: Medial (if referring to the midline), but third is medial to second? Yes.
But it’s lateral to fourth.
So unless it's asking for relationship to both, it's ambiguous.
But in standard usage: The third metacarpal is medial to the second (because second is lateral), and lateral to the fourth (because fourth is medial).
But the question says “to the second and forth” — plural.
So likely: Between? Not a directional term.
Best answer: Medial (since it's closer to the midline than second and fourth? No — third is central).
Actually, second is lateral to third, fourth is medial to third — so third is medial to second and lateral to fourth.
But the term must be consistent.
Perhaps the intended answer is: Medial — meaning it’s toward the midline compared to second and fourth? But second is lateral, fourth is medial.
This is confusing.
Likely intended: Intermediate — but not standard.
Or perhaps: Central — not standard.
Alternatively, the question may have a typo.
But in many contexts, the third metacarpal is medial to the second and lateral to the fourth, so no single term fits.
But if we interpret “to the second and forth” as collectively, then:
→ Medial (relative to second) and lateral (relative to fourth) — not possible.
Best guess: Medial — assuming comparison to second.
But actually, the third metacarpal is medial to the second metacarpal (yes), and lateral to the fourth.
So no single term.
Wait — perhaps the intended answer is intermediate? But not a standard term.
In many worksheets, they expect: Medial (as in, the third is medial to the second).
But the fourth is medial to the third.
So perhaps: Medial and Lateral? But blank is singular.
Maybe the question means: “the third metacarpal is ___ to the second and fourth” — i.e., between them.
Then: Intermediate — but not standard.
Another possibility: Central — but not standard.
Given ambiguity, best answer: Medial (if they’re thinking of second as lateral, third as medial) — but fourth is medial.
Actually, second is lateral, third is medial, fourth is medial — wait, no:
- Metacarpal 1 (thumb): lateral
- 2: lateral
- 3: central
- 4: medial
- 5: medial
So:
- Third is medial to second (yes)
- Third is lateral to fourth (yes)
So no single term.
But if the question is asking: “the third metacarpal is ___ to the second and fourth”, it might mean: between them.
So: Intermediate — but not a directional term.
Alternatively, adjacent?
But likely, the expected answer is: Medial — but that’s only true relative to second.
Or perhaps: Central?
I think the intended answer is: Medial — but it's inaccurate.
After checking common sources: Often, such questions expect:
→ Medial (if comparing to second)
But better: Between — but not a standard term.
Let's skip for now.

42. The Rt & Lt lungs are ___ to each other.
→ Contralateral
*Explanation:* Right and left lungs are on opposite sides.

43. The Rt upper limb and Rt lower limb are ___ to each other.
→ Ipsilateral
*Explanation:* Both are on the right side.

44. The lining of the sacs housing the lungs is called ___ pleura.
→ Visceral
*Explanation:* Visceral pleura covers the lungs.

45. The outer covering (shiny, slippery) on the lung surface is called ___ pleura.
→ Parietal
*Explanation:* Parietal pleura lines the thoracic cavity.
