During the first 2 months of gestation - 🧠ANSWER ✔✔The skin
differentiates into different layers
In late teenage years - 🧠ANSWER ✔✔Adult skin thickness and
characteristics achieved
1 year of age - 🧠ANSWER ✔✔Melanin reaches adult levels by this age
,2 years - 🧠ANSWER ✔✔Vascularization is well developed by
6-12 mo
7 years old - 🧠ANSWER ✔✔Sebaceous glands cease production
between_______and become active again around__________.
2 and 18 days
2 or 3 years - 🧠ANSWER ✔✔Eccrine sweat functions begin between
__________, full function not in place until_________.
During puberty - 🧠ANSWER ✔✔Apocrine glands become active
Epidermis - 🧠ANSWER ✔✔o Protective barrier, comprised of 5 layers of
stratified squamous epithethlium
o Basal layer keratinocytes shed and mature about every 28 days
Outer Layer - epidermis - 🧠ANSWER ✔✔stratum corneum, protects
against microorganisms and irritating chemicals
Melanin - (epidermis) - 🧠ANSWER ✔✔protects DNA from damage from UV
light, produced in basal layer and contributes to color of skin, eyes, and hair
,Dermis - 🧠ANSWER ✔✔o Thicker middle layer, contributes to strength,
support, and elasticity; regulates heat loss, provides host defenses, and
aids in nutrition and other regulatory functions
o Primarily composed of fibrous connective tissue (fibroblasts and
collagen), with some elastic fibers and mycopolysaccharide gel; includes
mast cells, inflammatory cells, blood and lymph vessels, and cutaneous
nerves that elicit sensations (touch, pain, pressure, itch, warmth, and cold)
Subcutaneous tissue - 🧠ANSWER ✔✔o Primarily adipose tissue, contains
arteries and arterioles for thermoregulation
o Insulates, cushions, provides energy, and metabolizes hormones
Eccrine glands - 🧠ANSWER ✔✔over entire body, maintain fluid and
electrolyte balance and body temp, and provide some excretory function
o Ceruminous glands - 🧠ANSWER ✔✔in external ear canal and secrete
cerumen
o Apocrine glands - 🧠ANSWER ✔✔located in axillary, genital, and
periumbilical areas, open into hair follicles, require androgens to stimulate
their secretions, and thought to be responsible for body odor

, • Sebaceous glands - 🧠ANSWER ✔✔found in conjunction with hair
follicles, secrete sebum when stimulate by androgen and function to
prevent excessive water evaporation, minimize heat loss, and lubricate skin
and hair
Epidermis - 🧠ANSWER ✔✔provides functional barrier
Dermis - 🧠ANSWER ✔✔provides strength and protection through
cutaneous nerves
Subcutaneous tissue - 🧠ANSWER ✔✔ensures insulation, is a cushion,
energy source, and hormonal metabolism
o Pigment lability
o Follicular response
o Mesenchymal response - 🧠ANSWER ✔✔Three cutaneous reactions to
trauma, infection, or inflammation
Pigment lability - 🧠ANSWER ✔✔post inflammatory hyper or
hypopigmentation
Follicular response - 🧠ANSWER ✔✔prominent papule and follicle
formation (atopic dermatitis, pityriasis rosea, syphilis
