Question

the dermis
the dermis (deep layer of the skin) is made of 2 layers:
the papillary layer and the reticular layer. the papillary
layer is the superficial 1/5 of the dermis. the reticular
layer is the lower 4/5 of the dermis.

1. in the picture to the right color the epidermis in pink.

remember, the epidermis is the layer below the
epidermis but above the adipose - tissue - filled
hypodermis. color the hypodermis in yellow. using
the data provided above and your best estimations,
color the papillary layer of the dermis in green and
the reticular layer of the dermis in blue.

1. on page 6, label the epidermis (1) and color it pink.
2. on page 6, label the hypodermis. also label the

adipose tissue (2) that makes up the hypodermis
yellow.

1. on page 6, label the papillary layer of the dermis

and the reticular layer of the dermis.
the papillary layer of the dermis
the papillary layer contains several important parts. if you look at the top of the papillary layer,
you will see slight ridges that bind the epidermis to the dermis. these ridges are known as dermal
papillae, which translates into \skin nipples.\ the dermal papillae create a strong connection
between the epidermis and the dermis, like a zipper. the dermal papillae can also form larger
mounds in the feet and hands known as dermal ridges. these ridges cause the patterns on our
hands and feet... and ultimately allow us to leave fingerprints!
on page 6, color the dermal papillae orange by shading orange just below the epidermis.
remember, the dermal papillae are the ridges where the epidermis and dermis meet.

1. which layer of the dermis are the dermal papillae in?
2. what are two functions of the dermal papillae?

another important structure within the papillary layer of the dermis are sensory receptors called the
meissners corpuscles. meissners corpuscles sense light touch, such as a loved one lightly
brushing their hand against your arm.
on page 6, label the meissners corpuscles (3) and color them light green.

1. which layer of the dermis are the meissners corpuscles in?
2. what do the meissners corpuscles sense?

also found within the papillary layer of the dermis are sensory receptors known as free nerve
endings. like the meissners corpuscles, these nerve endings contribute to the sense of touch.
specifically, the free nerve endings sense pain, damage, extreme heat, and extreme cold.
on page 6, label the free nerve endings (4) and shade over them in brown... © science from scra

Explanation:

1. The dermal papillae are in the papillary layer of the dermis as the text states that if you look at the top of the papillary layer you will see the dermal papillae.
2. The two functions of the dermal papillae are to bind the epidermis to the dermis and to create the patterns on our hands and feet (ultimately allowing for fingerprints).
3. The Meissner's corpuscles are in the papillary layer of the dermis as the text mentions they are an important structure within the papillary layer.
4. The Meissner's corpuscles sense light touch, such as a loved - one lightly brushing their hand against your arm.

Answer:

1. Papillary layer of the dermis
2. Bind the epidermis to the dermis; create hand and foot patterns (fingerprints)
3. Papillary layer of the dermis
4. Light touch
