Portage Learning: A&P 1 Module 7
The integumentary system is comprised of what three parts of the body? - Answer Hair,
skin, and nails
List the three layers of the skin from superficial to deep. - Answer Epidermis, Dermis,
Hypodermis
Describe three functions of the integumentary system. - Answer Production of vitamin
D; contain sense organs for protection of skin and underlying tissue; protection from
pathogens
True or false: Thermoreceptors detect fine touch. - Answer False
Merkel's cells and Meisner's corpuscles are thermoreceptors - Answer False
True or false: Pacinian corpuscles detect pressure. - Answer True
Describe what an exocrine gland contains and how its contents reach the surface of the
skin. - Answer Exocrine glands contain secretions which are released through a duct
(opening) into an epithelial surface or lining.
Basement Membrane - Answer Layer between epithelium and underlying connective
tissue
Epidermis - Answer Outer layer of skin
Dermis - Answer middle layer of skin
subcutaneous Fat - Answer layer of fat cells beneath the skin that helps conserve body
heat
Subcutaneous Tissue - Answer Tissue, largely fat, that lies directly under the dermis
and serves as an insulator of the body.
Merkel Cell - Answer receptor cell in the stratum basale of the epidermis that responds
to the sense of touch
Meissner's Corpuscles - Answer sensitive touch receptors in the dermis
Pacinian Corpuscle - Answer a type of nerve ending located in the subcutaneous layer
that is sensitive to pressure; also described as "lamellated"
Sensory Nerve - Answer a nerve that conveys information from the body to the central
nervous system
, Oil - Answer
Sweat Gland - Answer The glands that secrete sweat, located in the dermal layer of the
skin.
Sebacous Gland - Answer Oil glands that are found all over the skin, produce sebum
What is a sebaceous gland? - Answer Sebaceous glands (oil glands) produce sebum
(oil).
What is the purpose of thermoregulation in the body? - Answer Thermoregulation helps
the body to regulate its temperature. Perspiration is one method in assisting
thermoregulation.
True or false: The epidermis is made up of stratified cuboidal epithelium. - Answer False
(stratified squamous epithelium)
What are the four layers of the epidermis? - Answer Stratum corneum, stratum
granulosum, stratum spinosum and stratum basale
True or false: Cells of the stratum basale have a high rate of cell division. - Answer True
The cells of the stratum basale have epidermal ridges which are the basis for each
person's distinct pattern called - Answer Fingerprint
True or false: Dead cells in the stratum corneum remain for about 2 weeks before they
slough off. - Answer True
These types of cells produce keratin. - Answer Keratinocytes
These types cells produce melanin. - Answer Melanocytes
What are the two layers of the dermis? Which layer contains the main blood supply for
the skin? - Answer Papillary and reticular; the reticular region contains the main blood
supply
What is the medical term for a bruise? - Answer Contusion
What is one of the purposes of the hypodermis? - Answer Fat helps to insulate and
regulate body temperature; The thickness of the hypodermis protects the deeper tissues
and organs from injury.
What is a dermatome? - Answer A region of skin innervated by one sensory nerve.
