CORRECT ANSWERS) /ALREADY GRADED A+
Keratin - ANSWER: a protein substance that helps protect the skin against invasion
keratinization - ANSWER: the process of living cells moving upward and changing to
dead calls
the two main zones of the epidermis - ANSWER: 1. horny zone
2. germinal zone
horny zone layers - ANSWER: 1. stratum corneum
2. stratum lucidium
3. stratum granulosum
(act as a barrier against invasion and water absorption)
stratum corneum - ANSWER: outer most layer of the skin where dead skin cells are
constantly shed
stratum lucidum - ANSWER: second layer of the skin that is transparent due to
eleidin and only on the palms of your hands and soles of your feet
stratum granulosum (granular layer) - ANSWER: bottom layer of the horny zone.
THICKEST on the soles of the feet and palms of the hands, THINNEST on the eyelids.
Forms calluses.
Germinal Zone Layers - ANSWER: 1. stratum spinosum
2. stratum germinativum
stratum spinosum - ANSWER: prickle cell layer
stratum germinativum (basal cell layer) - ANSWER: the LOWEST layer of the
epidermis, in contact with the dermis.
cell division (mitosis) occurs here
Stratum Mucosum - ANSWER: the malpighian layer
The Dermis - ANSWER: the living layer or "true skin"
Meissner's Corpuscles - ANSWER: nerve endings sensitive to touch
in the papillary layer
The Reticular Layer - ANSWER: the THICKEST layer of the skin
made of collagen fibers
,Appendages of the Reticular layer - ANSWER: arrector pili muscles
blood vessels
fat cells
hair follicles
lymph vessels
nerve endings
sebaceous glads- oil
sudoriferous glands- sweat
As the blood supply circulates through the skin it... - ANSWER: transports the
oxygen-rich blood and nutrients essential for growth; reproduction; and tissue repair
of the skin, hair, and nails
Lymph glands produce - ANSWER: lymph
lymph - ANSWER: white blood corpuscles and plasma
contains waste products, salts, and nitrogenous wastes
sudoriferous glands - ANSWER: the sweat glands under the control of the
sympathetic nervous system
Apocrine Glands (smelly) - ANSWER: in the pubic and axillary (underarms) area
excrete pheromones
eccrine glands (everywhere) - ANSWER: all over the body
more in the foreheads, palms of hands, and soles of feet
Sebaceous glands (oil glands) - ANSWER: all over the skin
mainly appendages to the hair follicles and open into the shafts of hair follicles.
more on the scalp, T-zone, and cheeks
produce sebum (oil)
are of the philosebaceous unit
influenced by the endocrine system
most active during puberty
the philosebaceous unit - ANSWER: the hair
arrector pili muscle - ANSWER: an appendage that is attached to the hair follicle
partially responsible for heat regulation
subcutaneous layer (adipose tissue) - ANSWER: a layer of fatty tissue at the base of
the dermis
layers of the hair - ANSWER: 1. cuticle (protection)
2. cortext (pigment)
3. medulla (strength of the hair)
, Anagen - ANSWER: hair's active growing phase, the hair follicle is at its deepest
catagen - ANSWER: the hair follicle separates from the dermal papilla
shortest growing phase (only a few days-a few weeks)
telogen - ANSWER: resting stage, when papilla reaches the bulge
functions of the skin (PHRASES) - ANSWER: 1. protection
2. heat regulation
3. absorption
4. secretion
5. excretion
6. synthesis of vitamin D
Sebum - ANSWER: prevents drying and cracking and prevents bacteria and germs
from entering the skin and the body
germinal layer (stratum germinativum) - ANSWER: contains melanin-producing
melanocytes that protect the body from harmful ultraviolet radiation
adipose tissue in the subcutis - ANSWER: cushions the body from falls, protects
against minor trauma, and provides a source of energy
heat regulation - ANSWER: the body adjusts to counteract environmental changes
and to maintain a safe and appropriate temperature through EVAPORATION,
PERSPIRATION, RADIATION, and INSULATION
secretion and excretion - ANSWER: during perspiration, salts, urea, and other waste
material are excreted through the sudoriferous glands and rise to the surface of the
skin
sensation - ANSWER: the body experiences heat, cold, pain, pressure, and itch
absorption and penetration - ANSWER: the skin can absorb oil- and fat-based
substances to differing levels but not water.
topical creams can be absorbed into the blood supply
Vasoconstriction - ANSWER: narrow, makes smaller, calming (cooling)
Vasodilation - ANSWER: open, widening, irritation, redness
What does sunlight stimulate? - ANSWER: melanocytes to increase pigment
production and more widely disperse their melanosomes
langerhan calls - ANSWER: are dendritic cells in the epidermis that have an
immunologic function.
