What is a papillary dermis?
The papillary dermis is the upper layer of the skin itself, which is used to protect the body from the outer environment. It contains blood vessels that supply skin tissue with basic nutrients and oxygen and also regulate body temperature. This layer of Dermis also includes free nerve endings in sensitive parts of the body. Nerves help protect the body from danger, such as sharp objects and heat, and send messages to the brain and spinal cord to protect the body by regulating body temperature or avoiding pain sources.
The most important function of the papillary dermis is the protection of muscles and internal organs of the body. The skin is actually an external organ that is elastic and stretches all over the body. It maintains bacteria and other harmful materials in contact with sensitive and vulnerable skin systems that keep humans and other animals alive.
The papillary dermis contains blood vessels that serve two primary functions. One of these functions is to provide the tissue of the skin vital nutrients and oxygen. Blood vessels also removeThe used, oxygen blood from the skin to create space for fresh blood.
The second function of the blood vessels in the papillary dermis to regulate the body temperature. The nerves present in the skin tell the body what the ambient temperature is. This information can be used to protect or dispersion by increasing or reducing blood flow to the dermis.
Free nerve endings are also included in the papillary dermis in highly sensitive areas of the body, such as fingers and genitals. These nerves are directly connected to the brain and spinal cord through the peripheral nervous system. The nerves are located in the upper layer of the skin to best determine the surrounding environment. They can tell the body that it is too cold or too hot in the surrounding environment that will use the central nervous system to protect or distract heat.
nerves in the papillary dermis can also feel the danger in the surrounding environment other than temperature. These nerves are responsible fromand sending messages of brain pain and connected nervous system. When trauma or other source pain is detected on the skin, the nerves send a body reaction that determines how the body reacts to feeling. This can be experienced when the skin comes into contact with the sharp edge and the nervous system reacts by causing a person to throw away from the source of pain.
