This vitamin is produced when UVB light penetrates the skin.
What is vitamin D?
100
This is the most superficial layer of the epidermis, comprised of dead cells full of keratin.
What is the stratum corneum?
100
Abrasions are especially painful because these, most common sensory receptors, are exposed to the environment after the protective cells above them have been scraped off.
What are free nerve endings?
100
This is the sweat gland most commonly found in places like the armpit and groin, that not only secret sweat, but also pheromones that communicate with the olfactory senses of those around you.
What are apocrine sweat glands?
100
This type of cancer is found in squamous cells of the stratum spinosum.
What is squamous cell carcinoma?
200
These glands will secrete a liquid to help keep the body temperature from getting too high.
What are eccrine sweat glands?
200
These cells produce pigment that determine hair and skin color.
What are melanocytes? (Found in the stratum basale)
200
This degree of burn damages nerve cells to the point that it will feel numb afterward.
What is a third degree burn?
200
These muscles, attached to the skin surface and hair follicle, are responsible for goosebumps.
What are arrector pili?
200
This cancer is often found in areas of high sun exposure, forms black nodules and starts in the stratum basale.
What is basal cell carcinoma?
300
These are two purposes of sebaceous glands. (No credit for just one...)
What are lubricating the skin,
keeping moisture in,
produce sebum to keep hair from cracking,
inhibit bacterial growth,
keep skin pliable
300
This epidermal layer is only found in thick skin of the hands and feet.
What is stratum lucidum?
300
These cells, discovered by a German scientist, detect light touch and are disc shaped.
What are Merkel cells?
300
These glands, attached to hair follicles, produce sebum to protect the skin, and when overactive can cause acne.
What are sebaceous glands?
300
This is the most fatal type of skin cancer, most likely to metastasize, starting in the melanocytes.
What is melanoma? (malignant melanoma)
400
Other than sweating, skin will take on great amounts of this liquid to help regulate body temperature.
What is blood? (vasodilation causes blood to pool in the skin)
400
Most of the epidermis is comprised of one main type of epithelial cell called this....(because they are layered and do not have a block-type shape)
What are stratified squamous cells?
400
This is located at the end of a nerve, specially designed to feel deep pressure and vibration.
What is a Pacinian Corpuscle?
400
This tissue, found in the hypodermis, serves as dense energy storage (fat) and insulates the body.
What is adipose tissue?
400
These cells in the skin produce and immune response to pathogens trying to enter the body.
What are Langerhans Cells?
500
Nails are a great protection for the fingers and work as tools because they are made up of this hard protein.
What is keratin? (Secreted by keratinocytes!)
500
This is the deepest layer of the epidermis, comprised of highly mitotic columnar cells.
What is the stratum basale?
(Also contains melanocytes and sits on the 'basement layer' that separates it from the dermis...)
500
This disease related to blood sugar regulation can cause nerve damage due to blood vessels that supply nutrients to nerves, especially in feet and hands.
What is diabetes?
500
These glands are found in the external auditory canal and produce a waxy substance that lubricates and fights bacteria.
What are ceruminous glands?
500
This is the type of medicine often prescribed to help patients suffering from an overactive immune response like lupus, eczema, or psoriasis.
What are steroids?
