Here are the functions matched with the corresponding structures of the skin:
- **Muscles:** These are primarily responsible for the movement of hair follicles and the contraction of the skin (like goosebumps) in response to cold or emotional stimuli. They can also aid in the expression of emotions through facial movements.
- **Oil glands:** These glands (sebaceous glands) produce sebum, which helps to lubricate and waterproof the skin and hair, keeping them moisturized and preventing them from becoming dry and brittle.
- **Nerve endings:** These structures are responsible for sensing various stimuli, such as touch, temperature, pain, and pressure. They play a critical role in the skin's ability to relay information to the brain about the environment.

The two main structures of the integumentary system involved with controlling the temperature of the body are:
1. **Sweat Glands:** These glands help regulate body temperature by producing sweat, which cools the skin as it evaporates.
2. **Blood Vessels:** The network of blood vessels in the skin can dilate (widen) or constrict (narrow) to help release or retain heat, respectively. When it's hot, blood vessels dilate to increase blood flow to the skin's surface, promoting heat loss. Conversely, they constrict when it’s cold to conserve body heat.
Together, these structures work to maintain homeostasis in the body temperature.

Certainly! Here’s a brief overview of the skin and hair, focusing on their structures and functions:
### Skin
**Structure:**
1. **Epidermis:** The outermost layer of the skin, composed primarily of keratinocytes, which provide a barrier and protection. This layer also contains melanocytes (which produce melanin, the pigment responsible for skin color) and Langerhans cells (involved in immune response).
2. **Dermis:** Beneath the epidermis, this thicker layer contains connective tissue, blood vessels, hair follicles, and various glands (sweat and sebaceous/oil glands). The dermis is responsible for the skin's strength and elasticity.
3. **Hypodermis (Subcutaneous Layer):** The deepest layer, composed of fat and connective tissue, which helps insulate the body and absorb shock.
**Functions:**
- **Protection:** Acts as a barrier against pathogens, UV radiation, and physical injuries.
- **Temperature Regulation:** Regulates body temperature through the sweat glands and blood vessel dilation/constriction.
- **Sensation:** Contains nerve endings that respond to touch, pain, pressure, and temperature.
- **Vitamin D Synthesis:** The skin synthesizes vitamin D when exposed to sunlight.
### Hair
**Structure:**
1. **Hair Shaft:** The visible part of hair that extends above the skin surface.
2. **Hair Follicle:** The structure within the skin from which hair grows. It includes the hair bulb (where hair originates) and is surrounded by the dermal papilla, which supplies nutrients.
3. **Sebaceous Gland:** Attached to hair follicles, these glands secrete sebum, which conditions the hair and skin.
**Functions:**
- **Protection:** Hair provides a protective barrier (e.g., eyelashes protect the eyes, and nose hair filters particles).
- **Temperature Regulation:** Hair helps to retain heat when it stands up (through muscle contraction), as well as providing insulation.
- **Sensation:** Hair follicles have nerve endings that can detect slight movements, helping to sense the environment.
Together, the skin and hair play crucial roles in maintaining overall body health, protection, and sensory perception. If you have any specific questions about skin or hair, feel free to ask!
