What surfaces of the body have papillary ridges?
fingers, palms, heels, and toes
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.
What is the principle behind DNA fingerprinting?
there are technically 3 1.the characteristic is unique to the individual of papillary ridges, 2. the fingerprint will remain unchanged during a persons lifetime, and 3. fingerprints have general ridge patterns which allow them to be systematically classified. im a police officer and i found this out over my training course

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.
Why is the papillary layer responsible for fingerprint?
papillary layer is responsible for fingerprints
What muscle is attached to the chordae tendineae?
papillary muscles
Does the skin include the papillary layer?
The papillary layer of the skin is one of two layers of the dermis.
