What is function of the papillary layer?
The Papillary is the upper layer of the dermis that has ridges and valleys causing finger prints. It has receptors which communicate with the central nervous system, these include touch, pressure, hot, cold and pain receptors.
Does the papillary layer consist of areolar connective tissue?
Yes, the papillary layer of the skin consists of areolar connective tissue.
Where are the palmar and plantar surfaces on the body?
They are on your hands and on your feet!
Tissue covers the surfaces of structures inside the body?
epithelial
What does our body contain that is approximately 100?
The closest is the number of fingerprint ridges on the index finger of one hand.
What part of the dermis gives rise to friction ridges?
Papillary Layer
Italian doctor who studied skin and papillary ridges?
Marcello Malpighi
What is responsible for the dermal ridges that produce whorled ridges on the epidermal surfaces?
Dermis
What is the site of the dermal ridges that produce epidermal ridges on the epidermal surfaces of the fingers called?
fingerprints

What is the dermal layer responsible for fingerprints?
The dermal layer responsible for fingerprints is the papillary layer.stratum germinativum
What are epidermal ridges and dermal papillae?
Epidermal Ridges: the ridges of the epidermis found in the palms and soles, where the sweat pores open; form in fetus as epidermis conforms to the dermal papillae aka fingerprints Dermal Papillae: finger like projections in the papillary region of the dermis where the epidermis conforms for fingerprints
The papillary layer of the dermis is connective tissue heavily invested with blood vessels The superficial surface has structures called?
It produces the ridges that make fingerprintsdermal papillae.
What causes the ridges and valleys to form in fingerprints?
Below the top layer of the skin, the epidermis, is the dermis.At the top of the dermis lies the papillary layer which connects with the deepest layer of the epidermis, the stratum germinativum. The papillary layer supplies blood and nutrients to the germinativum with lots of dermal papillae which form waves all along this layer. These waves form the ridges and valleys to form fingerprints which show on the epidermis.
What are the surfaces in the body where friction ridges are found?
All surfaces that come into contact with each other generate friction. The magnitude of the friction depends on the specific properties the two surfaces. General rule: smooth surface --> less friction. But this fails sometimes too.
Why is the papillary layer responsible for fingerprint?
papillary layer is responsible for fingerprints
