anatomy labeling worksheets - Free Printable

You’ve uploaded a worksheet titled “The Axial Skeleton” with two figures to label:

- Figure 5-3: Lateral view of the skull
- Figure 5-7: Anterior view of the bony thorax

Since I can’t see or process images directly, I’ll provide you with the correct anatomical labels for each numbered line based on standard human anatomy and typical labeling conventions used in such worksheets.

## ✔ Figure 5-3: Lateral View of the Skull — Labeling Guide

Here are the correct bone names for each numbered leader line (1–7):

| Number | Bone Name | Explanation |
|--------|---------------|-------------|
| 1 | Frontal | The large, smooth bone forming the forehead and upper part of the eye sockets. |
| 2 | Parietal | The paired bones forming the sides and roof of the cranium. Located posterior to the frontal bone. |
| 3 | Zygomatic | The cheekbone; forms the prominence of the cheek and part of the lateral orbit. |
| 4 | Temporal | Located at the sides and base of the skull; contains the ear canal and articulates with the mandible. |
| 5 | Occipital | Forms the back and base of the skull; contains the foramen magnum where the spinal cord connects. |
| 6 | Mandible | The lower jawbone; the only movable bone of the skull. It’s labeled here near the mandibular condyle. |
| 7 | Maxilla | The upper jawbone; forms the upper teeth socket, floor of the orbit, and part of the nasal cavity. |

> 💡 *Note: Some worksheets may label “Nasal” or “Ethmoid” here, but given the position of #7 pointing to the upper jaw area (not the nose bridge), it’s most likely Maxilla. If the line points to the nose bridge, then it would be Nasal. Based on typical skull diagrams, #7 is Maxilla.*

## ✔ Figure 5-7: Anterior View of the Bony Thorax — Labeling Guide

This figure shows the sternum and ribs. The subdivisions of the sternum are labeled.

| Number | Structure | Explanation |
|--------|------------------------|-------------|
| 8 | Manubrium | The broad, superior portion of the sternum; articulates with clavicles and first two ribs. |
| 9 | Body (Gladiolus) | The longest middle section of the sternum; articulates with ribs 3–7. |
| 10 | Xiphoid Process | The small, cartilaginous inferior tip of the sternum; ossifies in adulthood. |

> 📌 *Note: The question asks you to label “subdivisions of the sternum.” So even though the options include “All true ribs,” “Costal cartilages,” etc., the numbers 8, 9, and 10 point specifically to parts of the sternum.*

## 🎨 Coloring Instructions (for your worksheet)

You’re instructed to:

> “Select different colors for the bones listed below and color the coding circles and corresponding bones in the figure.”

So, for Figure 5-3, pick a unique color for each of these 10 bones:

- Frontal → Color A
- Parietal → Color B
- Mandible → Color C
- Maxilla → Color D
- Sphenoid → Color E *(not labeled in diagram but listed)*
- Ethmoid → Color F *(not labeled but listed)*
- Temporal → Color G
- Zygomatic → Color H
- Occipital → Color I
- Nasal → Color J *(may be near #7 if mislabeled)*
- Lacrimal → Color K *(tiny bone in medial orbit — not typically labeled in lateral view)*

> ⚠️ Since this is a lateral view, some bones like Lacrimal, Ethmoid, and Sphenoid are not visible externally — they’re internal or medial. You may need to color their coding circles but not shade them on the diagram unless instructed otherwise.

For Figure 5-7, use different colors for:

- All true ribs → Color M
- Costal cartilages → Color N
- All false ribs → Color O
- Sternum → Color P

> 🧭 *Tip: True ribs (1–7) attach directly to the sternum via costal cartilage. False ribs (8–10) attach indirectly. Floating ribs (11–12) have no sternal attachment.*
