Dermis
The lower layer of the dermis where collagen and elastin are more tightly packed together.
What is the reticular layer?
What is the stratum germinativum?
This cell produces pigment granules that are distributed to the skin cells.
What is a melanocyte?
This is the type of melanin that produces yellow and red pigment.
What is pheomelanin?
This is another name for the motor nerves that influence muscle and glandular activity.
What are efferent nerves?
The papillary layer of the dermis is considered this type of tissue.
What is connective?
In this layer, the skin cells become spiky with appendages called desmosomes that allow for intercellular communication.
What is the stratum spinosum?
What is a keratinocyte?
This is the enzyme that stimulates the production of melanin.
What is tyrosinase?
What are sensory or afferent nerves?
This protein fiber found in the dermis that gives the skin its stretch.

This layer is known for its translucent cells.
What is the stratum lucidum?
This is a guard cell that protects the body from pathogens.
Brightening agents that cause the skin to lighten by disrupting enzymatic processes.
What are tyrosinase inhibitors?
These nerves control the actions of the arrector pili muscles.

The production of keratin and intercellular lipids takes place in this layer.
What is the stratum granulosum?
This is the division of cells that creates two identical daughter cells.
What is mitosis?
This is a spherical structure that carries pigment granules.
