The hair follicle is also known as the pilosudoriferous unit or pore.tf
f
Sebum help maintain the water level in the cells by:
coating the skin's surface and slowing down TEWL
The layer just above the papillary dermis is known as the basal layer or the reticular layer tf
f
Red-yellow melanin is known as eumelanin and pheomelanin is dark brown-black. tff
f
Sebum is the oily substance produced by the sebaceous gland which coats the epidermic scales and gives protection from external factors.tf
t
The barrier function of skin is created by the production of:
intercellular cement and sebum
Fibroblasts make the ground substance, collagen, and elastin.tf
t
Papillae are fingerlike ridges in the upper part of the dermis that help form an attachment to the epidermis and also contains tiny blood vessels called capillaries that help to nourish the stratum corneum.tf
f
What makes up 70% of the dermis:
collagen
Four colours – red, yellow, brown, and black – are found in the skin.tf
f
Inflammation increase melanocyte activity and melanin production.tf
t
Which sublayer is found in the upper portion of the dermis:
papillary
What surrounds the cells in the dermis:
ground substance
What type of gland produces perspiration and is not attached to a hair follicle
eccrine
Which skin division is found below the dermis of the skin:
subcutaneous
Elastin is not flexible, and gives skin its firmness and inability to stretch.tf
f
Lamellar bodies assist in the production of intercellular cement.tf
f
The sweat glands in the underarm and groin are called
apocrine
Fibroblasts are responsible for:
the formation of collagen
The jelly-like substance in the dermis or Ground substance is made primarily out of the GAG known as hyaluronic acid.tf
t
The main function of the sebaceous gland is to regulate body temperature.tf
f
What is ground substance?
fluid between the fibers in the dermis
Sebum, dead corneocytes and intercellular cement are all part of the barrier function of the skin.tf
t
Which layer contains collagen and elastin fibrils?
reticular
Which layer connects the dermis to the epidermis:
papillary
Which is true of sebaceous glands?
their glands are connected to the hair follicles
The yellow colouring of the skin is caused by natural carotenoids as well as the amount of carotenes consumed.tf
t
Hyaluronic acid is a major component of the dermal matrix or ground substance and as a strong water binder it helps retain fluid in the epidermis.tf
