A child is playing on the playground barefoot when she steps on a wooden part of the playset and gets a splinter in the heel of her foot. Her father removes the splinter, which had penetrated three layers of her epidermis. Which epidermal layers did the splinter go through?
Stratum corneum, stratum lucidum (since it is the foot and there is thick skin there), and stratum granulosum(Concept 1 page 4)
What layer is made of epitheleal tissue?
epidermis( Concept 1 page 3)
Where is the Stratum Corneum located
stratum corneum is the outer layer of the skin epidermis. It serves as the primary barrier between the body and the environment.( Concept 1 page 4 and BBD)
The projections from the surface of the dermis into the epidermis are called the
Dermal Papillae(Concept 1 page 4)
Where is the Stratum Lucidum located?
The stratum lucidum is a smooth, seemingly translucent layer of the epidermis located just above the stratum granulosum and below the stratum corneum.(Concept 1 page 4 and BBD)
Where is the basal layer located?
The basal layer is the innermost layer of the epidermis, and contains small round cells called basal cells(BBD)
The projections from the surface of the dermis into the epidermis also contain ________ that allow us to feel pain.
nerve endings(concept 1 page 7)
The epidermal layer that only exists in thick skin, such as the soles of the feet and the palms of the hands.
Stratum Lucidum(Concept 1 page 4)
Meissner’s Corpuscles are located in the dermal papillae and are responsible for sensing
light pressures and vibrations(Concept 1 page 4)
Based on their location, which epidermal layer are the projections from the surface of the dermis into the epidermis closest too?
Stratum Basale(Concept 1 page 4)
Which of the following is an example of the chemical protection the skin provides?
low ph secretions(Concept 1 page 7)
The majority of the dermal layer, made of dense irregular connective tissue called
reticular dermis(Concept 1 page 4)
Where is the stratum spinous located?
Spinous cells are found in the superficial layers of the skin. They are found in the stratum spinosum, which lies above the stratum basale (basal layer) and below the stratum granulosum (granular layer) of the epidermis.(Concept 1 page 4 and BBD)
Where are new cells made?
stratum basale( Concept 1 page 4)
What provides nourishment for the more superficial layer ?
dermis(Concept 1 page 4)
What cells make up the majority of the epidermis. The ones on the surface of our skin are dead and we shed many of them every day?
Keratinocytes(Concept 1page 3)
What are the functions of the epidermis?
absorbs shock, stores energy, and insulates from heat loss(Concept 1 page 3)
What is the tough and water-resistant layer of the skin where cells are filled with keratin called
Stratum granulosum(Concept 1 page 4)
What cells patrol beneath the surface of the skin to attack foreign invaders and activate the immune system.?
Langerhans cells (Dendritic)(Concept 1 page 6)
