Section 1
What are the two LAYERS of skin?
Epidermis (outer layer) & Dermis (inner layer)
What is the purpose of sweat glands and how does the sweat reach the surface?
The purpose is to control our body temperatures and secrete waste (sweat). The sweat reaches the surface by exiting the bodies pores.
What is one "function" of the arrector pili?
Smooth muscle contracts to raise hair due to different reasons (fright, nervous, etc.)
What are the two main things sweat is made up of?
Salt & water
This layer is farther away from the nutrients deep within the dermis, so the skin cells die.
Sebaceous gland
Describe the types of tissues: connective, smooth, epithelial, & nervous
Connective- connects deep dermis to muscle
Smooth- lines internal organs
Nervous- carries messages to and from the brain
Epithelial- covers the epidermis (outer layer)
What does the deep dermis (subcutaneous layer) mainly consist of?
Adipose (fat tissue) and glands
How do your skin help with maintaining homeostasis
Regulates body temperature as needed (cools down through sweat, and provides warm when cold)
Name at least three functions of the skin
Protection, temperature regulator, sensations, storage of chemical compounds, synthesis of chemical compounds, excretions of waste
Some tattoo ink can contain high levels of iron oxides, which can cause what to your skin if you were to get an MRI for a medical reason
Burn your skin
BONUS:
Why is it important to understand the function of skin
To help identify what could possibly be wrong with someone if they are experiencing symptoms that involve the function of the skin.
Describe the two layers of skin
Epidermis- outer layer, ashy/dry, dead skin cells, avascular
Dermis- inner/deep layer, glands, fat tissue, connective tissue, vascular
Even though we have hair all over our bodies, it has a minor role for humans. What is one role hair has?
Protection, thermoregulation (temperature regulation)
BONUS:
As a medical field employee, if you have someone come in with a rash that is red and raised in an area or all over, what could you be your possible answer as to why
Allergic reaction to something (common item would be a medication- severe is known as Toxic Epidermal Necrolysis)
