What are the three main layers of the skin?
What are the epidermis, dermis, and subcutaneous (hypodermis)?
The skin helps regulate body temperature through this function.
What is heat regulation?
These cells produce melanin.
What are melanocytes?
What gland produces sebum?
What is the sebaceous gland?
Which protein provides skin with firmness and strength?
What is Collagen?
This is the outermost layer of the epidermis.
What is the stratum corneum?

What are keratinocytes?
What is the function of the sudoriferous glands?
What is to produce sweat?
Which protein allows skin to stretch and return to its original shape?
What is elastin?
This layer of the dermis contains blood vessels, hair follicles, and sweat glands.
What is the reticular layer?
Sebum helps protect the skin through this function.
What is secretion?
What immune cells are found in the epidermis to fight bacteria and foreign substances?
What are Langerhans cells?
Which type of sweat gland is found mostly in the armpits and groin?
What are apocrine glands?
Both collagen and elastin are produced by these cells.
What are fibroblasts?
Which layer of the epidermis is only found on the palms and soles?
What is the stratum lucidum?
This function allows certain substances to pass into the skin.
What is absorption?
These dermal cells produce collagen and elastin.
What are fibroblasts?
These tiny muscles are attached to hair follicles and cause goosebumps.
What are arrector pili muscles?
As we age, these two proteins decrease, causing wrinkles and sagging.
What are collagen and elastin?
In which layer of the skin do mitotic (cell division) activities occur?
What is the stratum basale (or stratum germinativum)?
Name all 6 major functions of the skin.
What are protection, sensation, heat regulation, excretion, secretion, absorption?
This cell type detects touch in the skin.
What are Merkel cells?
What is the difference between eccrine and apocrine glands?
Eccrine glands are all over the body and regulate temperature; apocrine glands are in the underarms/genital area and are triggered by hormones.
What professional treatments can stimulate collagen production in the skin?
What are microneedling, chemical peels, LED light therapy, and/or retinol-based products?
