How does the hypodermis differ from the dermis?
a.The hypodermis is composed of areolar connective tissue and adipose
tissue, located below the dermis, and connects skin to the underlying
fascia.
b.The hypodermis is responsible for temperature regulation and forms
finger-like dermal papillae.
c.The hypodermis is rich in melanocytes, located below the dermis, and
provides insulation and cushioning.
d.The hypodermis is composed of dense connective tissue, located
above the dermis, and serves as the core of the skin.
a.The hypodermis is composed of areolar connective tissue and adipose
tissue, located below the dermis, and connects skin to the underlying
fascia.
___________ cells function as a macrophage that protects our skin
from bacteria, foreign particles, and damaged cells.
a.Merkel cells
b.Langerhans cells
c.Melanocyte
d.Keratinocytes
b.Langerhans cells
, Identify the correct statement about the papillary layer of the dermis.
a.It forms a tight meshwork of collagen and elastin fibers.
b.It contains a large number of adipocytes for fat storage and provides
insulation.
c.It projects into the stratum basale, contains blood vessels, and houses
Meissner corpuscles.
d.It is responsible for melanin synthesis and pigmentation.
c.It projects into the stratum basale, contains blood vessels, and houses
Meissner corpuscles.
Match the following skin functions with their appropriate description.
Skin Function
1. protection
2. Sensory Function
3.Thermoregulation
4.Vitamin D synthesis
Description
D. Skin acts as a barrier against water loss, due to the presence of
keratin and glycolipid layers.
A. Pacinian corpuscle receptors respond to vibration.
B. Constriction and dilation of the arterioles based on the surrounding
environment.
C. Essential for normal absorption of calcium and phosphorus.
