Epidermis
This type of tissue makes up the epidermis and provides protection against abrasion and water loss.
What is keratinized stratified squamous epithelium
The dermis is primarily made of this type of connective tissue, which provides strength and elasticity.
What is dense irregular connective tissue
What are the two plexus names?
What is the Subpapillary plexus and Cutaneous plexus
What is the method of secretion of the Sebaceous Gland.
What is holocrine secretion via Sebum
These cells in the epidermis are associated with sensory nerve endings and help you feel light touch.
What are Merkel cells (tactile cells)?
These specialized cells produce melanin, the pigment responsible for skin color?
What are melanocytes?
What is the diagram pointing towards?
What is Dermis
Where is the Subpapillary plexus and Cutaneous plexus on this diagram?

What is the method of secretion of the Ceruminous gland?
Apocrine via Ear Wax
These keratinized structures grow from follicles in the dermis and help protect the scalp and body.
What are hairs?
Based on the diagram, identify which image represents thick skin and which represents thin skin.
Right : Thick Skin
Left : Thin Skin
This top layer of the dermis has tiny bumps called dermal papillae that help make fingerprints.
What is Papillary Layer
What are the main functions of the papillary layer plexus compared to the cutaneous plexus?
What is
- the papillary plexus supplying blood to upper dermis and the epidermis for nutrient exchange
- cutaneous plexus supplies the deeper dermis and hypodermis
What is the function of the Eccrine Gland?
What is Provides Protection for environmental hazards.
These glands produce an oily substance that keeps the skin and hair soft and waterproof.
What are sebaceous glands?
These immune cells found in the epidermis help detect and fight pathogens that enter through the skin.
What are Langerhans cells?
This deeper layer of the dermis makes up about 80% of its thickness and contains collagen fibers that form cleavage lines.
What is Reticular Layer
How do the two dermal vascular plexuses help regulate body temperature?
What is
- conserving heat or dilating to release heat
-adjusting blood flow between the papillary and cutaneous plexuses.
What Gland starts producing once an individual hits puberty?
Apocrine Gland.
This small muscle attached to each hair follicle causes “goosebumps” when it contracts.
What is the arrector pili muscle?
Although avascular, the epidermis receives nutrients and oxygen through this process from the underlying dermis.
What is diffusion?
While the epidermis is avascular, the dermis is well supplied with blood vessels. These vessels connect to the hypodermis, which primarily consists of this tissue type that helps insulate the body and absorb shock.
What is adipose tissue
This dermal blood network lies near the epidermis and helps nourish it and regulate temperature.
What is the papillary plexus?
What layer does Thick skin have that thin skin does not have?

Made mostly of keratin, these protect the tips of your fingers and toes.
What are nails?
