The image you've provided is a diagram from a textbook (Chapter 5: The Skeletal System, page 85) showing
Figure 5–8, which illustrates the
scapula (shoulder blade), a bone of the
appendicular skeleton. The task is to:
1. Identify the bone in Figure 5–8.
2. Label the structures indicated by leader lines using the options:
- Spine
- Glenoid cavity
- Coracoid process
- Acromion
Let’s go step-by-step.
---
✔ Step 1: Identify the Bone
The bone shown in
Figure 5–8 is the
scapula.
>
✔ Answer:
Scapula
---
✔ Step 2: Identify and Label the Structures
Now, let's match each labeled part in the diagram with the correct anatomical term.
#### 🔹 Structure 1: Topmost projection (above the glenoid cavity)
This is the
acromion — a bony projection that forms the highest point of the shoulder and articulates with the clavicle.
>
✔ Label:
Acromion
#### 🔹 Structure 2: Deep socket on the lateral side
This is the
glenoid cavity (also called the glenoid fossa) — it articulates with the head of the humerus to form the shoulder joint.
>
✔ Label:
Glenoid cavity
#### 🔹 Structure 3: Small hook-like projection near the superior border
This is the
coracoid process — a small, hook-shaped projection that serves as an attachment site for muscles and ligaments.
>
✔ Label:
Coracoid process
#### 🔹 Structure 4: Ridge running across the posterior surface
This is the
spine of the scapula — a prominent ridge that divides the scapula into supraspinous and infraspinous fossae.
>
✔ Label:
Spine

🧩 Final Answer:
Labeling the diagram from top to bottom (following the leader lines):
1.
Top projection (above glenoid cavity) →
Acromion
2.
Lateral depression (socket) →
Glenoid cavity
3.
Small hook near superior border →
Coracoid process
4.
Ridge across the back →
Spine

🎨 Coloring Instructions (as per task)
You are to:
- Select different colors for each structure.
- Color the
coding circles next to each label.
- Use the same color to shade the corresponding structure in the diagram.
For example:
- Color "Spine" circle → use that color to shade the spine ridge.
- Color "Glenoid cavity" circle → shade the socket.
- And so on.

✔ Summary
Bone in Figure 5–8: Scapula
Labels:
- Top projection:
Acromion
- Lateral socket:
Glenoid cavity
- Hook-like process:
Coracoid process
- Ridge across back:
Spine
These are all key features of the scapula, forming part of the
shoulder girdle and playing essential roles in arm movement and stability.
