Study Notes
- The stratum germinativum and stratum corneum are layers of the epidermis.
- Tanning is associated with melanocytes.
- A fetus is covered with vernix caseosa
- "Sweat" describes sudoriferous.
- When blood vessels of the skin dilate, the person appears flushed.
- Ceruminous glands secrete wax in the outer ear.
- Freckles and moles result from an accumulation of melanin.
- A congenital absence of eccrine glands leads to an inability to regulate body temperature.
- Radiation, conduction, convection, and evaporation are terms related to heat loss.
- Hives are called urticaria.
- Skin supplied by oxygen-poor blood is described as cyanotic.
- The dermis lies on the subcutaneous layer.
- Keratin makes the skin water resistant.
- Contraction of the arrector pili muscles results in goosebumps.
- Sebaceous glands secrete vernix caseosa in the fetus.
- Sebaceous glands are most likely to develop a blackhead or pimple.
- Apocrine glands are most responsible for body odor.
- Mammary glands and ceruminous glands are modified sweat glands.
- Constriction of blood vessels conserves heat.
- Exercising causes sweating and flushing to lose heat.
- Shivering increases heat production.
- Melanoma has the poorest prognosis.
- The subcutaneous layer insulates the body from extreme temperature changes.
- The epidermis is avascular.
- Carotene is the yellow pigment found in skin.
- Vitamin D, produced by the skin, is necessary for calcium absorption.
- Anticancer drugs often cause hair loss, a condition called alopecia.
- Sweat glands usually associated with hair follicles and found in the axillary and genital areas are called apocrine glands.
- Vasodilation is most likely to lower body temperature.
- A callus is the name of the thickening of the epidermis that develops in response to constant pressure or irritation.
- The stratum germinativum is mitotically active.
- The secretion of fetal sebaceous glands results in the fetus being covered by vernix caseosa.
- The hypodermis is also called the subcutaneous layer.
- Sebaceous, apocrine, and eccrine glands are exocrine.
- Nonshivering thermogenesis is accomplished by metabolism associated with brown fat.
- The epidermal layer is nourished by blood vessels in the dermal layer.
- A characteristic of the dermal layer is that it is nourished by blood vessels in the epidermal layer.
- The cells are continuously dividing, pushing older cells toward the surface of the cutaneous membrane indicates the stratum germinativum.
- The stratum corneum is (a) the outermost layer of the epidermis, (b) an epidermal layer, and (c) nourished by blood vessels within the dermis.
- The subcutaneous layer contains adipose tissue, and cushions, binds, and insulates.
- Melanocytes secrete a tanning pigment in response to exposure to sunlight.
- Cyanosis refers to a bluish coloring of the skin caused by hypoxemia.
- Sebaceous glands are exocrine glands.
- Eccrine glands are sweat glands.
- Apocrine glands become active at puberty, are exocrine glands, and are found primarily in the axillary and genital areas.
- Vernix caseosa is a cream cheese-like substance covering the skin of the fetus.
- The hypothalamus is the body's thermostat, can be affected by pyrogens, and is involved in thermoregulation.
- Flushing is generally accompanied by activation of the eccrine glands to lose heat.
- Shivering produces heat.
- Brown fat is found in the fetus and neonate and is concerned with nonshivering thermogenesis.
- Rectal temperature is a measurement of core temperature.
- Keratin is a protein that hardens and makes an epidermal cell water resistant.
- The epidermis does not sit on the subcutaneous layer
- Exfoliation and desquamation is the sloughing off of dead cells by the stratum corneum.
- Dander and dandruff are composed of dead skin cells.
- Hirsutism may occur in response to abnormal secretion of hormones such as steroids.
- The hair follicle is composed of epithelial cells.
- With aging hair becomes gray and then white as melanocytes become less active.
- Sudoriferous glands are sweat glands, participate in temperature regulation, and include eccrine and apocrine glands.
- Normal body temperature is maintained through thermoregulatory mechanisms.
- Using a cooling blanket to lower body temperature works through conduction.
- A person feels warmer on a humid day because the decrease in evaporation of water from the skin surface decreases the loss of heat.
- Hyperthermia is characterized by elevated body temperature, the elevated temperature caused by the inability of the body to get rid of excess heat, and does not respond to the antipyretic effect of aspirin.
- A fever involves the upward resetting of the hypothalamus and often responds to the antipyretic effect of aspirin.
