Stratum granulosum
What layer of the Epidermis is the most superficial?
Stratum Corneum
What activity will exposure to the sun stimulate in the body?

Will the Epidermis have blood vessels?
No
Where is the Pacinian Corpuscle located?
Deep in the Reticular Layer of the Dermis
What are the sudoriferous glands?
Eccrine/Apocrine sweat glands
What tissue can be found in the Hypodermis?
Adipose Loose CT Proper
What is the role of the Pacinian Corpuscle?
Deep pressure

Somatosensory
What are the layers of the skin?
Epidermis
Dermis
Hypodermis
Function of sebaceous glands? Type of epithelium? Gland structure?
Secretes oil (sebum) to condition hair and skin
Stratified Cuboidal Epithelium
Simple branched alveolar
Location and function of Meissner Corpuscle?
Dermal Papillae (high density in finger tips) Sensitive to light touch
What layer is inferior to the Papillary layer, and what type of CT Proper is it made from?
Reticular layer, Dense Irregular layer
Eccrine gland is?
Sweat glands found all over the body (more in palmar and plantar) contain stratified cuboidal epithelium. Simple coiled tubular structure.
Apocrine Gland is?
Sweat gland found in axillary region, groin, face, nipples.
Produces milky sweat leading to body odor.
