Skin Conditions
100

Deepest layer of skin provides insulation, stores fat, and connects the skin to underlying muscles and bones.

What is the hypodermis

100

They gather at an area where skin barrier is broken to rebuild it.

What are platelets

100

Most common type of cancer, caused by uncontrolled growth of skin cells.

What is skin cancer

100

This largest sensory organ contains millions of receptors that detect touch, pressure, vibration, pain, temperature, and texture.

What is skin

100

Eczema mainly affects this outermost layer of the skin, which protects against bacteria and keeps skin hydrated.

What is the epidermis

200

Cells in the skin’s connective tissue that release collagen and help form the skin’s structure.

What are fibroblasts

200

These surface secretions contain antimicrobial compounds like defensins and lysozymes that destroy pathogens before they enter the body.

What is sweat and sebum

200

Pigment-producing cells in the stratum basale that can develop into the most dangerous type of skin cancer.

What are melanocytes

200

These pathways carry information from the skin to the brain, allowing you to feel touch, temperature, and pain.

What are afferent pathways

200

Skin condition that causes itchy, red bumps and sometimes fluid-filled blisters.

What is eczema

300

This process transforms living cells into dead ones, forming the protective outer layer of skin.

What is keratinization

300

Specialized cells in the epidermis that act as “guards,” capturing pathogens and presenting them to T cells in lymph nodes.

What are langerhans cells

300

This slow-growing cancer starts in stratum basale keratinocytes and usually appears as a shiny bump on sun-exposed areas.

What is basal cell carcinoma (BCC)

300

Division of the autonomic nervous system that triggers “fight or flight” responses in the skin, such as sweating, redness, and goosebumps.

What is the sympathetic division

300

Eczema mainly affects this outermost layer of the skin, which protects against bacteria and keeps skin hydrated.

What is the epidermis

400

This layer of the epidermis is where new skin cells are born before moving upward.

What is the stratum basale
400

immune system attacks melanocytes, leading to loss of skin pigment.

What is vitiligo

400

Doctors use this five-part rule to check spots for asymmetry, border, color, diameter, and changes over time.

What is the ABCDE rule

400

Hormone, sometimes called the “bonding hormone,” that's released during positive touch like hugs or gentle brushing, reducing stress and increasing trust.

What is oxytocin

400

This condition causes redness and flushing mainly on the cheeks, nose, chin, and forehead.

What is Rosacea

500

 a layer that is deeper down, which is made of dense connective tissue and contains larger blood vessels, nerves, sweat and oil glands, and hair roots.

What is the reticular layer of the dermis

500

Immune molecules released by keratinocytes and immune cells that act as messengers, coordinating inflammation and tissue repair.

What are cytokines

500

Aggressive skin cancer that starts in touch receptor cells and is usually seen as a firm, painless lump.

What is merkel cell carcinoma (MCC)

500

Specialized receptors detect harmful stimuli and trigger reflexive withdrawal, teaching protective behaviours and linking the skin to emotional well-being.

What are nociceptors 

500

Both eczema and rosacea can flare up due to triggers like stress, allergens, or temperature, and are sometimes treated with these to reduce inflammation or infection.

What are oral or topical medications
