1Which of the following is a skin sensory receptor for touch
- AMeissner's corpuscle
- BFree nerve ending
- CBasal lamina
- DRuffini body
2The function of the root hair plexus is to _____
- Acause apocrine gland secretion into the hair follicle
- Ballow the hair to assist in touch sensation
- Cserve as a source for new epidermal cells for hair growth after the resting stage has passed
- Dbind the hair root to the dermis
3Melanocytes and keratinocytes work together in protecting the skin from UV damage when keratinocytes _____
- Aaccumulate melanosomes over their nuclei, forming a protective shield from UV damage
- Bprovide the melanocyte with nutrients necessary for melanin synthesis
- Cmaintain the appropriate temperature so the product of the melanocyte will not denature
- Dmaintain the appropriate pH in order for the melanocyte to synthesize melanin granules
4A splinter penetrated into the skin of the sole of the foot, almost to the papillary region of the dermis. Which layer of the epidermis would be the final layer injured
- Agranulosum
- Bspinosum
- Cbasale
- Dlucidum
5Which of the following protects us against excessive water loss through the skin
- Athe dermis is the thickest portion of the skin and water cannot pass through it
- Bglycolipids that are secreted by keratinocytes into extracellular spaces
- Cfat associated with skin prevents water loss
- Dthe size and shape of the cells that make up the stratum spinosum, as well as the thick bundles of intermediate filaments
6Sudoriferous (sweat) glands are categorized as two distinct types. Which of the following are the two types of sweat glands
- Aholocrine and mammary
- Beccrine and apocrine
- Csebaceous and merocrine
- Dmammary and ceruminous
7which layer of tissue is damaged in first-degree burn
- Adermis
- Bepidermis
- Chypodermis
- Dboth the epidermis and dermis
8The reason the hypodermis acts as a shock absorber is that ____
- Athe major part of its makeup is adipose, which serves as an effective shock absorber
- Bthe cell that make up the hypodermis secrete a protective mucus
- Cit has no delicate nerve endings and can therefore absorb more shock
- Dit is located just below the epidermis and protects the dermis from shock
9Despite its apparent durability, the dermis is subject to tearing. How might a person know that the dermis has been previously stretched and/or torn
- Athere is an episode of acute pain due to the large number of tactile corpuscles
- Bthe blood vessels in the dermis rupture and the blood passes through the tissue, causing permanent "black and blue marks"
- Cthe appearance of visible, silvery-white scars is an indication of stretching of the dermis
- Dthe stretching causes the tension lines to disappear
10The dermis has two major layers. Which layer constitutes 80% of the dermis and is responsible for the tension lines in the skin?
- Athe reticular layer
- Bthe papillary layer
- Cthe subcutaneous layer
- Dthe hypodermal layer
11Which of the following cells and their functions are correctly matched?
- Amelanocytes- protects cells in the stratum corneum from damaging effects of sun rays
- Btactile cells- protection
- Ckeratinocytes- provide sense of touch and pressure
- Ddendritic cells- activate the immune system
12A needle would pierce the epidermal layers of the forearm in which order?
- Acorneum, granulosum, spinosum, basale
- Bbasale, spinosum, granulosum, lucidum, corneum
- Cbasale, spinosum, granulosum, corneum
- Dgranulosum, basale, spinosum, corneum
13A light skinned person who is very cold may have a pale appearance. which of the following is the best explanation for why this might be so?
- AThe person is experiencing hypothermia
- Bthe cold has slowed the movement of blood
- Cthe persons blood vessels in the dermis have undergone vasoconstriction (narrowing)
- Dthe person's blood vessels in the epidermis have undergone vasodilation (widening)
14The composition of the secretions of the eccrine glands is _____
- Ametabolic wastes
- Bprimarily uric acid
- C99% water, sodium chloride, trace amounts of wastes, and vitamin C
- Dfatty substances, proteins, antibodies, and trace amounts of minerals and vitamins
15Cells of the stratum spinosum have many interlocking desmosomes that will remain between the cells as they migrate to the stratum corneum. These cell junctions serve as the body by _____
- Astopping water loss and preventing dehydration
- Ballowing secretions like sweat or sebum to pass through
- Cpreventing ultraviolet light from penetrating the deeper layers of the epidermis
- Dpreventing mechanical stress or trauma from damaging the epidermis
16A patient has skin that is slightly blue in color. A likely treatment for this person might be ______
- Agiving the patient supplemental oxygen by mask
- Bencouraging the patient to eat more orange colored vegetables (rich in beta carotene)
- Cincreasing fluids through IV therapy
- Dexposing the patients to more sunlight
17William has a cut that is superficial, painful but not bleeding. Based on this information, you would predict that the cut has penetrated to ____
- Athe stratum basale but not the dermal layers
- Bthe papillary layer but not the reticular layer
- Cthe subcutaneous layer, but no deeper
- Dthe stratum corneum but not the stratum granulosum
18Burns are devastating and debilitating because of loss of fluids and electrolytes from the body. How do physicians estimate the extent of burn damage associated with such dangerous fluid loss?
- Aby using the "rule of nines"
- Bthrough blood analysis
- Cby observing the tissues that are usually moist
- Dby measuring urinary output and fluid intake
