Skin Plaque Model

Epidermis

Sensory reception (pain, touch/temperature) / waterproofing

Dermis

Stratum Corneum

Keratinized, 20-30 cell layers

Stratum Lucidum

Pams of the hand / soles of the feet

Stratum Granulosum

Lamellated Granules / Keratohyaline Granules

Stratum Spinosum

Langerhans cells / keratinocytes

Stratum Basale

Melanocytes / Merkel cells

Papillary Layer

Highly vascularized, nourishes the epidermis

Reticular Layer

glomerulus/ tubular ball of sweat gland or eccrine sweat gland

produce perspiration/ part of body's heat regulatory apparatus

moistens hair

hair arrector pili muscle

Connects follicle to the papillary layer/exerts pressure on sebaceous gland/pulls follicle upright/causes goosebumps

(Part of the follicle)

Papilla of Hair

Nourishes growing hair

Pacinian corpuscles

Pressure / sensory reception

Merkel discs

Sensory reception, light touch
