Skin Layers
The outermost layer of the skin acts as a barrier to protect underlying tissues.
What is the epidermis?
This function of the skin helps regulate body temperature through sweat production and blood flow adjustments.
What is thermoregulation?
These cells are responsible for producing melanin, the pigment that gives skin its color.
What are melanocytes?
These hair-follicle-associated glands secrete an oily substance that helps to keep skin and hair moisturized.
What are sebaceous glands?
This common skin condition is characterized by red, itchy patches and is often linked to inflammation.
What is eczema?
This layer of the skin contains connective tissue and houses blood vessels, hair follicles, and glands.
What is the dermis?
This function of the skin helps in the synthesis of vitamin D when exposed to sunlight.
What is vitamin D synthesis?
These immune cells in the skin help to protect against pathogens and play a role in allergic responses.
What are Langerhans cells?
These hair-like structures help to detect fine touch and are concentrated in areas like the fingertips to help us detect our external environment.
What are Meissner's Corpuscles?
This skin condition is characterized by the rapid multiplication of skin cells, leading to scaling and inflammation.
What is psoriasis?
This deepest layer of the skin contains adipose tissue, which serves as insulation and energy storage.
What is the hypodermis?
This function of the skin helps in the sensation of pain, pressure, and temperature, allowing the body to respond to stimuli.
What is sensory perception?
These cells are responsible for producing collagen and elastin, which provide strength and elasticity to the skin.
What are fibroblasts?
These structures produce sweat, which helps in regulating body temperature through evaporation.
What are sudoriferous glands?
This type of burn affects only the outer layer of the skin, causing redness and minor pain.
What is a first-degree burn?
This layer of the epidermis contains dead, flattened keratinocytes that provide a tough barrier against environmental damage?
What is the stratum corneum?
This process, which narrows blood vessels in the skin, helps to conserve body heat in cold environments.
What is vasoconstriction?
What are keratinocytes?
These tiny openings on the surface of the skin allow for the excretion of sebum and play a role in hair growth.
What are hair follicles?
This common condition occurs when hair follicles become clogged with oil and dead skin cells, leading to inflammation.
What is acne?
This dermis layer is composed of loose areolar connective tissue and contains many blood vessels and nerves.
What is the papillary layer?
This primary function of the skin acts as a barrier against pathogens, chemicals, and physical injuries, helping to maintain overall health.
What is protection?
These cells are found in the epidermis and are responsible for sensing light touch and pressure.
What are Merkel cells?
These sensory structures respond to deep pressure and vibration and are located deeper within the dermis.
What are Pacinian corpuscles?
These non-inflammatory acne lesions are caused by clogged pores that remain open at the surface, resulting in a dark appearance.
