epidermis
Which layer of the integument contains the stratum basale?
epidermis
Which tissue layer deep to the integument acts as a shock and thermal insulator?
hypodermis
Which connective tissue layer is discussed in the chapter on the integumentary system but is truly not a part of it?
hypodermis
Which of the following is a sensory receptor?
Pacinian corpuscle
The only cell type found superficial to the stratum spinosum in the epidermis is the
keratinocyte
A sebaceous gland is classified as a ________ gland.
simple alveolar
The epidermis is a keratinized ________ epithelium.
stratified squamous
Which primary layer of the skin contains lamellated granules that aid in waterproofing?
epidermis
Identify the layer of the skin that contains most of the sensory receptors.
dermis
Which epidermal cells are part of the immune system?
dendritic cells
The papillary layer of the dermis consists of ________ connective tissue
areolar
Which layer of the epidermis contains keratohyalin granules and lamellated granules?
stratum granulosum
The reticular layer of the dermis consists of ________ connective tissue.
dense regular
In the thick skin of the palm, the layer of the epidermis directly deep to the stratum corneum is the stratum
lucidum
In addition to nourishing the epidermal cells, the dermal blood vessels function in
thermoregulation.
Which is the most abundant and widespread type of sweat gland?
eccrine
When a blister forms due to friction, liquid pools between the epidermis and what other layer of the integument?
dermis
Which connective tissue layer s found deep to the dermis?
hypodermis
The thickness of skin is determined by the presence of the stratum lucidum and the thickness of the
stratum corneum.
Holocrine secretion
involves the bursting of the glandular epithelial cell.
Which layer of the skin invaginates downward to form sebum-producing glands?
epidermis
Is the human integumentary system best adapted for hot or cold climates?
warm, because sweating cools us in hot climates but we would die in cold climates without clothing
Since both hair and skin contain keratin, the hair shaft is most comparable to what part of the epidermis?
stratum corneum
Based on the rule of nines, approximately what percent of the total body surface covers the anterior and posterior torso?
37%
The type of burn in which the epidermis and part of the dermis are damaged is ________ degree.
second
Skin consists of two distinct tissue layers: the epidermis and dermis.
True
Keratinocytes begin to die in the stratum granulosum.
false
An immediate concern with a burn patient is loss of fluids, so fluids must be administered immediately.
true
First-degree burns are the most severe type of burn.
false
If you are truly “smelly” after a workout that causes you to work up a sweat, the smell is due to secretions from your eccrine glands.
false
Sebaceous glands secrete oil onto the surface of the epidermis via the hair follicle.
true
By the time keratinocytes reach the stratum corneum, they are dead and filled with collagen.
true
What kind of CT is the papillary layer made of?
areolar CT
Function (s) of melanocytes?
UV protection
Keratinocytes and Dendritic cells (Langerhans cells) are seen in
stratum spinosum
Name the epidermal layer fully keratinized?
Stratum corneum
what term means pertaining to a type of tissue that does not have blood vessels?
avascular
Sweat contains
water, salts and wastes.
If you cut yourself and pathogen enter the wound, which of the following cells would help get rid of the pathogen?
Langerhans cells
