The 2 layers of the integumentary system.
What are the dermis and epidermis?
100
These are biologically active catalysts that accelerate chemical reactions.
*Note: They only facilitate reactions that would already occur.
What are enzymes?

Images of this type of connective tissue seen from under a microscope is pictured here.
What is elastic cartilage?
100
These types of glands lack ducts and secrete hormones directly into the blood.
What are endocrine glands?
200
This layer of the skin is only found in thick skin, such as the soles of the feet or the palms of the hands.
What is the stratum lucidum?
200
Listed below are examples of skin conditions that can be exacerbated by a deficiency in this.
- Psoriasis
- Atopic dermatitis
- Acne vulgaris
- Hidradenitis Suppurativa

What is Vitamin D?

An image of this type of connective tissue under a microscope is viewed here.
What is fibrocartilage?
200
These are the 3 types of exocrine glands that are classified by their method of secretion.
What are the merocrine, apocrine, holocrine glands?
300
The only mitotic layer of the epidermis.
What is the stratum basale? (Or the germinativum)
300
An example of this type of reaction would be the hydrolysis of sucrose into the products glucose and fructose.
What is a decomposition reaction?
(Or, what is a catabolic reaction?)
300
Images of this type of connective tissue as viewed under the microscope are pictured here.
What is hyaline cartilage?
300
This gland is the most common type of exocrine gland, secreting fluids through exocytosis. Examples of this gland include salivary glands, much of the pancreas, and sweat glands.
What is a merocrine gland?
400
The papillary and reticular layers of the dermis.
What are the 2 layers of the dermis in order from superficial to deep?
400
This organ in our body converts vitamin D3 (cholecalciferol) into calcidiol using enzymes like vitamin D 25-hydroxylase.
What is the liver?
400
This type of connective tissue involves clumps of collagen fibers that provide support and resistance to stress in multiple directions. Can be found in the dermis of the skin or or perichondrium of cartilage.
What is dense irregular connective tissue?
400
Sebaceous (oil) glands are a type of this gland.
What is a holocrine gland?
500
The 5 layers of the epidermis in the correct order from superficial to deep.
What are the stratum corneum, the stratum lucidum, the stratum granulosum, stratum granulosum, stratum spinosum, and the stratum basale?
500
Calcidiol circulates in the blood and is converted into this by kidney enzymes like 25-hydroxyvitamin D3 1-alpha-hydroxylase.
What is calcitriol?
500
This type of connective tissue is highly vascularized, has abundant ground substance, and has many fibroblasts. Can be found in blood vessels, nerve cells, and a layer of the dermis.
What is areolar connective tissue?
500
Listed below are all examples of glands that fall under this type of gland category.
Pituitary gland, pineal gland, thyroid gland, parathyroid gland, and adrenal glands.
What are endocrine glands?
