The Integumentary System Worksheet | PDF - Free Printable

To solve this worksheet, we need to match the labels to the correct parts of the skin diagram. We will look at where each pointer is pointing and compare it to the list of terms provided.

Step-by-Step Deduction:

1. Top Right Pointer (Pointing to the outermost layer):
The line points to the very top surface of the skin section. This is the protective outer layer.
* *Match:* Epidermis

2. Second Right Pointer (Pointing to the thick middle layer):
The line points to the thick pink layer underneath the top layer. This layer contains blood vessels, hair roots, and glands.
* *Match:* Dermis

3. Third Right Pointer (Pointing to the bottom fatty layer):
The line points to the yellowish layer at the very bottom of the diagram, which acts as insulation.
* *Match:* Subcutaneous

4. Bottom Center Pointer (Pointing to the red vessel with a valve-like structure):
The line points to a blue/red tube carrying blood away from the heart area (indicated by the arrow direction usually associated with arteries in these diagrams, or simply distinguishing it from the vein). In many diagrams, the thicker-walled vessel is the artery. Let's look at the other vessel. The vessel on the left is labeled "Vein" typically if it has valves, but here let's look at the options. We have Artery and Vein. The pointer is on the vessel on the right side of the hair root. Usually, the Artery is paired with the Vein. Let's hold this and check the other vessel.

5. Left Side - Second Pointer from Top (Pointing to the blue vessel):
This points to the blue vessel running alongside the red one. Blue vessels in diagrams are typically veins.
* *Match:* Vein
* *Therefore, the previous one (Right side, red vessel) is likely the:* Artery

6. Left Side - Third Pointer from Top (Pointing to the coiled structure at the base of the hair):
The line points to the bulbous structure at the bottom of the hair shaft where growth happens.
* *Match:* Hair Shaft is the hair itself. The pointer is actually pointing to the *root* area, but looking at the options, we have "Hair Shaft". Let's re-examine.
* Wait, let's look closer at the left pointers.
* Left Top Pointer: Points to the hair sticking out. That is the Hair Shaft.
* Left Second Pointer: Points to the blue vessel. That is the Vein.
* Left Third Pointer: Points to the cluster of cells attached to the hair follicle. These are oil-producing glands.
* *Match:* Sebaceous (Oil) Gland

7. Left Bottom Pointer (Pointing to the opening on the surface):
The line points to the small hole on the skin surface where sweat comes out.
* *Match:* Sweat Pore

8. Right Side - Fourth Pointer (Pointing to the coiled gland deep in the dermis):
The line points to the tangled tubular structure at the bottom right that produces sweat.
* *Match:* Sweat Gland

9. Right Side - Fifth Pointer (Pointing to the tiny muscle attached to the hair follicle):
The line points to the small band of tissue connecting the hair follicle to the upper dermis. This muscle makes hair stand up (goosebumps).
* *Match:* Erector Muscle (also known as Arrector Pili)

10. Right Side - Sixth/Bottom Pointer (Pointing to the yellow fiber wrapping around structures):
The line points to the yellow strand that looks like a wire or cable. This carries signals.
* *Match:* Nerve

11. Missing Label Check:
We have used: Epidermis, Dermis, Subcutaneous, Artery, Vein, Hair Shaft, Sebaceous Gland, Sweat Pore, Sweat Gland, Erector Muscle, Nerve.
The only term left from the list is Melanin.
Looking at the diagram, there isn't a specific pointer clearly labeled for melanin in the standard positions, but often it is indicated within the epidermis. However, looking at the layout, we have 10 boxes on the right/left and 10-11 terms. Let's re-count the boxes.

*Right Side Boxes (Top to Bottom):*
1. Epidermis
2. Dermis
3. Subcutaneous
4. Sweat Gland
5. Erector Muscle
6. Nerve

*Left Side Boxes (Top to Bottom):*
1. Hair Shaft
2. Vein
3. Sebaceous (Oil) Gland
4. Sweat Pore
5. [There is a box pointing to the red vessel] -> Artery

Let's re-verify the "Artery" vs "Vein".
- Left side, 2nd box down: Points to the blue vessel. Blue = Vein.
- Left side, bottom box (actually it's the 4th box down on the left? No, let's trace carefully).

Let's trace the lines precisely from the image structure:

Right Side Labels (Top to Bottom):
1. Points to top layer: Epidermis
2. Points to middle pink layer: Dermis
3. Points to bottom yellow layer: Subcutaneous
4. Points to the coiled gland at the bottom right: Sweat Gland
5. Points to the small muscle on the hair follicle: Erector Muscle
6. Points to the yellow nerve fiber: Nerve

Left Side Labels (Top to Bottom):
1. Points to the hair sticking out: Hair Shaft
2. Points to the blue blood vessel: Vein
3. Points to the gland attached to the hair follicle: Sebaceous (Oil) Gland
4. Points to the red blood vessel: Artery
5. Points to the opening on the skin surface: Sweat Pore

Unused Term:
The term Melanin is in the list but there is no specific box for it in this specific crop/layout, or it might be considered part of the Epidermis description. However, based on the 10 visible boxes and 11 terms, Melanin is the extra distractor or implied within the epidermis. But wait, looking at the very bottom left, is there another box? No.

Actually, let's look at the "Artery" pointer again. The pointer for the red vessel is the 4th one down on the left.
The pointer for the "Sweat Pore" is the 5th one down on the left.

So the mapping is complete for the visible boxes.

Final Answer:

Right Side Labels (from top to bottom):
1. Epidermis
2. Dermis
3. Subcutaneous
4. Sweat Gland
5. Erector Muscle
6. Nerve

Left Side Labels (from top to bottom):
1. Hair Shaft
2. Vein
3. Sebaceous (Oil) Gland
4. Artery
5. Sweat Pore

*(Note: The term "Melanin" from the list is not assigned to a specific box in this diagram layout.)*
