RN Integumentary System EAQ EXAM Latest Version
hypodermis - ANSWER: layer of fat beneath the dermis also known as the
subcutaneous layer
epidermis - ANSWER: The outermost layer of skin designed to provide protection
dermis - ANSWER: Layer of skin found beneath the epidermis
cutaneous membrane - ANSWER: covers and protects body; aka skin
subcutaneous layer - ANSWER: located just below the skin, connects the skin to the
surface muscles; aka hypodermis
accessory structures - ANSWER: Hair, Exocrine Glands, and Nails are all known as
these types of structures.
acid mantle - ANSWER: layer of lipids and sweat secretions that help kill bacteria
stratified squamous epithelium - ANSWER: the type of tissue that the epidermis is
made of
dense connective tissue - ANSWER: the type of tissue that the majority of the dermis
is made of
adipose tissue - ANSWER: the type of tissue that the hypodermis is made of
avascular - ANSWER: the epidermis is considered to be this, as it is without blood
vessels
keratinocyte - ANSWER: Epidermal cells that produce keratin which makes the cells
more durable.
Epidermal cells that produce keratin which makes the cells more durable.
keratin - ANSWER: A fibrous protein that is the principal component of hair, skin, and
nails
melanocyte - ANSWER: cells that produce melanin
stratum corneum - ANSWER: the most superficial layer of the epidermis consisting of
dead cells
stratum lucidum - ANSWER: Clear, transparent layer of the epidermis under the
stratum corneum
absent in thin skin
, stratum granulosum - ANSWER: layer of the epidermis that has granules of
keratohyalin
keratohyalin - ANSWER: Protein found in the stratum granulosum which helps form
stronger keratin
stratum spinosum - ANSWER: Layer of the epidermis where the cells develop tiny
spines that assist in binding all cells tightly together
Stratum Basale - ANSWER: the deepest layer of the epidermis consisting of stem cells
capable of undergoing cell division to form new cells
desquamation - ANSWER: Shedding of epithelial elements; chiefly of the skin in
scales or sheets
keratinization - ANSWER: Process by which newly formed cells in the stratum basale
mature, fill with keratin, move upward, lose their nucleus, and die.
thick skin - ANSWER: Skin type on the palms and soles is characterized by the
absence of hair follicles and presence of stratum lucidum
thin skin - ANSWER: Type of skin that lacks a stratum lucidum, has hair, and is found
covering most of the body
papillary region - ANSWER: the superficial area of the dermis composed of areolar
connective tissue, dermal papillae, Meissner corpuscles of touch, and free nerve
endings
reticular region - ANSWER: the deeper part of the dermis consisting of dense
irregular connective tissue that interlaces in a net-like formation
dermal papillae - ANSWER: a fingerlike projection of the dermis that may contain
blood capillaries or Meissner corpuscles (of touch)
lanugo hair - ANSWER: 6 months before a child is born they develop fine downy hair
all over its body, this disappears one month before birth
terminal hair - ANSWER: long, coarse pigmented hair that replaces lanugo hairs on
the scalp, eyelids, and eyebrows.
vellus hairs - ANSWER: Short, fine, un-pigmented hair that covers the majority of the
body around the time of birth to replace the lanugo.
hair shaft - ANSWER: the portion of the hair that projects beyond the skin
hair root - ANSWER: The part of the hair located below the surface of the epidermis.
