Chapter 5 Integumentary(skin) Flashcards
Is skin a tissue, organ or a system?
Organ
Skins response to cold temperature
Vasoconstriction
Who is color of the skin due to deoxygenated hemoglobin
cyanosis
Oh that makes melanin in the epidermidis
melanocyte
Protein produced by keratinocytes sites to protect against abrasion
keratin
Phagocytic cell found in the epidermis
Langerhans cells
Touch Receptor found in the epidermis
Merkel cell
Deepest layer of the epidermidis were rapid mitosis of skins cells occurs
Stratum basale
Superficial layer of the upper dermis containing dead keratinocytes
Stratum corneum
Two basic layers of the skin
Epidermidis and dermis
Vascular layer of the skin
Dermis
Layer of areolar in adipose tissue found directly below the skin
Hypodermis
Two layers of the dermis
Papillary and reticular layers
Tissue of the papillary layer
Areolar
Tissue of the reticular layer of the skin
Dense irregular
Condition where part of the upper dermis is unable to make melanin creating a patch or more of white skin
Vitiligo
Condition where there is a complete inability to make melanin
Albinism
Orange pigment that accumulates in the stratum corneum
Carotene
Part of the hair above the skin
Shaft
Part of the hair below the skin
Root
Part of the hair that contains cells that form new hair
matrix
Nerve network around the hair roots
Hair plexus
Type of glandular secretion and sebaceous oil glands
Holocrine
Type of exocrine secretion found in sweat glands of the head neck and palms
Merocrine
Smooth muscle that runs between a hair follicle and the epidermis
Arrector pili
Exocrine glands found in the external auditory canal that produce wax
Ceruminous glands
Proteins that comprises hair and nails
Keratin
Termination of rapid cell mitosis when cells touch each other
Contact inhibition
Collagen repair that extends above and beyond the borders of the wound in the skin
Keloid scar
Skin cancer that often remains localized
Basal cell carcinoma
Burn that involves only the epidermis
First-degree burn
Burn that involves both the dermis and epidermis and leads to blistering
Second-degree burn
Vitamin responsible for calcium absorption from food
vitamin D
Layer of skin where hemoglobin is found
dermis
Product of sebaceous glands that inhibits bacterial growth on the skin
Sebum
