Skin Labelled Activity Worksheet - Beyond Secondary Science - Free Printable

The image you've uploaded is a worksheet titled "The Sense of Touch and the Skin", which asks students to label a diagram of the skin with the correct anatomical structures. The goal is to identify and label key components involved in the sense of touch and skin structure.

Task:

Label the following parts on the diagram:
- hair
- sweat gland
- oil gland
- blood vessels
- receptors

---

Step-by-step Solution & Explanation:

Let’s go through each part and identify where it should be labeled on the skin diagram:

#### 1. Hair
- Location: Hair grows from hair follicles, which are located deep in the dermis (the layer beneath the epidermis).
- How to identify: Look for the long, thin structure that extends upward from a bulb-like base (the hair follicle). It goes from the dermis through the epidermis and out of the skin surface.
- Labeling: Draw a line from the word "hair" to the visible shaft extending above the skin surface.

#### 2. Sweat Gland
- Location: Found in the dermis, usually coiled and connected to a duct that leads to the skin surface.
- How to identify: Look for a coiled tube-like structure that ends in a duct opening at the surface (often near or under the hair follicle).
- Labeling: Label the coiled structure as "sweat gland" — this helps regulate body temperature by producing sweat.

#### 3. Oil Gland (Sebaceous Gland)
- Location: Attached to hair follicles in the dermis, usually smaller and more rounded than sweat glands.
- How to identify: These glands are typically small, round sacs that connect to the side of a hair follicle.
- Labeling: Find the small sac-like structure attached to the hair follicle and label it "oil gland". These glands produce sebum to lubricate the skin and hair.

#### 4. Blood Vessels
- Location: Located in the dermis, forming a network around hair follicles, glands, and receptors.
- How to identify: Look for branching lines (like tubes) running through the dermis, often surrounding other structures.
- Labeling: Label the tubular network in the dermis as "blood vessels" — these supply nutrients and oxygen to skin cells.

#### 5. Receptors
- Location: Found in the dermis and sometimes near the epidermis; they detect touch, pressure, pain, and temperature.
- How to identify: Receptors appear as small, oval or spiral-shaped structures near the surface or embedded in the dermis.
- Labeling: Identify any small sensory structures (e.g., Pacinian corpuscles or Merkel cells) and label them as "receptors".

Final Answer (Labeling Guide):

| Structure | Where to Label |
|------------------|----------------|
| Hair | The long shaft extending from the follicle to the surface |
| Sweat gland | The coiled tube leading to a pore on the surface |
| Oil gland | The small sac attached to the hair follicle |
| Blood vessels| The branching network in the dermis |
| Receptors | Small sensory structures in the dermis |

Educational Notes:

- This diagram illustrates the epidermis (outermost layer), dermis (middle layer with glands, blood vessels, and nerves), and subcutaneous tissue (below).
- The sense of touch relies on sensory receptors in the skin that send signals to the brain via nerves.
- Understanding skin anatomy helps explain how we feel pressure, temperature, and pain.

✔ Tip for Students: Use a pencil first to practice labeling, then trace over with ink. Match the shape and position of each structure carefully.
