QuestionAnswer
Which layer of the epidermis is the deepest, and has hemidesmosomes to attach the cells to the basement membrane? Stratum basal/geminativum
Which layer of the epidermis is the most superficial, and consists of 25-30 layers of dead cells full of keratin Stratum corneum
Which layer of the epidermis is found only in the thick skin of the plantar and palmar surfaces? Stratum lucidum
Which layer of the epidermis has dark-staining specks in it? Stratum granulosum
Which layer of the epidermis is the second-deepest, and has the ability to produce new cells? Stratum Spinosum
Which layer of the epidermis gives rise to basal cell carcinoma? Stratum basale/germinativum
Which layer of the epidermis gives rise to squamous cell carcinoma? Stratum Spinosum
Skin that is cyanotic indicates lack of oxygen
Skin that is pallid indicates excessive bleeding (hemmorage)
Skin that is jaundiced indicates liver disease
Skin that is erythemous indicates allergy or fever
Skin that is darkened indicates hormonal imbalance
The main cell of the epidermis, responsible for protection from abrasion and infection, and against water loss or gain, is the keratinocyte
The pigment-producing cell of the epidermis, responsible for protection from ultraviolet radiation, is the melanocyte
The free nerve endings found in the epidermis are called nociceptors, meaning they respond to pain
The free nerve endings found in the dermis respond to heat and cold
The specialized nerve endings found in the epidermis that attach to Merkel cells and respond to very light touch, are called tactile discs
The specialized nerve endings found in the dermal papillae and respond to continuous touch, are called tactile corpuscles
The specialized nerve endings found deep in the dermis and respond to pressure and vibration, are called lamellated corpuscles
The specialized nerve endings found in the dermis and respond to stretch, are called Ruffini's corpuscles
The glands responsible for lubricating the skin are the sebaceous glands
The glands responsible for evaporative heat loss are the sudoriferous glands
The glands in the ear canal are the ceruminous glands
A vitamin partially manufactured in the skin is vitamin D
A rash develps whenever you wear nickel-based jewelry; you have contact dermatitis
Patches of nonpigmented skin develop because your immune system attacks your pigment-producing cells; you have vitilgo
Bedridden with a broken hip, you develop sores over your tailbone; you have decubitus ulcers
You break out in hives after a bee sting; you have urticaria
Supplies blood to nourish the epidermis The papillary plexus
The cutaneous plexus consists of the major blood vessels to the skin
Which layer of the epidermis consists of a single layer of cells anchored to the basement membrane by hemidesmosomes stratum basale
Which layer of the epidermis is found only in the thick skin of palmar and plantar surfaces Stratum lucidum
Which layer of the epidermis contains dark-staining particles of keratin Stratum granulosum
Which layer of the epidermis consists of multiple layers of cells capable of regeneration? Stratum spionosum
Which layer of the epidermis consists of multiple layers of flattened, dead cells? Stratum corneum
What type of epidermal cell is responsible for protecting the skin from ultraviolet radiation? melanocytes
What type of epidermal cell is responsible for protecting the skin from infection? dendritic (Langerhans) cells
What type of epidermal cell is responsible for protecting the skin from water gain or loss, as well as friction keratinocytes
What type of epidermal cell is responsible for responding to light touch? tactile (merkel) cells
What layer of the dermis connects the epidermis to the tougher, deeper dermal layer, and consists of deep folds with high surface area? papillary
What tissue type is found in the reticular layer of the dermis? irregular dense connective
What term is used for reddening of the skin? erythema
What term is used for the color of skin when oxygen is depleted? cyanosis
What term is used for the color of the skin when someone has liver disease jaundice
What term is used for lack of melanin production? albinism
What term is used for the color of skin when someone is bleeding to death pallor
The term for a bruise is hematoma
While it's true that ultraviolet light can harm the skin, it's also true that it is necessary for Vitamin D synthesis
What two responses to overheating can the skin produce? sweating and vasodilation
A common condition of aging males, that reduces the ability of their scalp to retain heat, is alopecia
The glands that are mostly responsible for heat loss are merocrine sweat glands
Skin cancer caused by the pigment cells of the skin is melanoma
Burns that form blisters are second degree
