The dermis consists of two layers: The papillary layer is a thin outer layer of areolar connective tissue with fingerlike projections called dermal papillae that protrude into the epidermis.
Simply so, What connects areolar tissue? Areolar connective tissue holds organs in place and attaches epithelial tissue to other underlying tissues. It also serves as a reservoir of water and salts for surrounding tissues. Almost all cells obtain their nutrients from and release their wastes into areolar connective tissue.

What is another name for papillary layer? The superficial layer of the dermis lying immediately under the epidermis into which it extends, forming dermal papillae. Synonym: stratum papillare.
Where is reticular dermis?
The thick bottom layer of the dermis (the inner layer of the skin). The reticular dermis has blood vessels and connective tissue that supports the skin. Hair follicles, oil and sweat glands, and other structures are also found in the reticular dermis.

Are fingerprints in the papillary layer?
The fingerprints are produced from a layer in the skin called the papillary layer, which is a layer within the dermis layer of skin. It produces an extra thick layer to form the ridges of fingerprints.
Are pain receptors in the papillary layer?

What connects skin to muscle? Explanation: The hypodermis is the deepest layer of the skin, and it consists of loose connective tissue called areolar tissue. As stated in the question, it connects the upper layers of the skin (the epidermis and dermis) to underlying muscle, acting like a glue.
Where do you find loose Areolar connective tissue?
Location. The areolar tissue is found beneath the dermis layer and is also underneath the epithelial tissue of all the body systems that have external openings.
