What is afferent?

In the anatomical auditorium is an afferent vessel or other pipes that bring substances to the central area, which is often the main organ such as the brain or heart. It is the opposite of an eperential container that transmits substances from these central places. Perhaps the most famous examples of these vessels are the veins of the circulatory system that bring deoxygenated blood back towards the heart. The lymphatic blood vessels that bring lymphatic fluid to the lymph nodes are also called afforents. Another example of this type of blood vessel is afferent neurons that pass sensory information to the central nervous system. They are similar to the structure of the eperential blood vessels known as arteries, with an outer layer composed of protective tissue, a middle layer made of muscle tissue and an inner layer made of epithelial cells, which are also smooth, almost without rubbing for fluids. One -way valves inside the veins ensure that blood, which is potentially full of waste products, does not flow back by the body. DeoxygenThe blood in the veins is actually dark red, but veins near the skin surface often appear blue because the skin causes a certain refractive of light.

lymphatic fluid is a term used to describe the interstitial fluid or fluid that exists between the cells after entering the lymphatic system. This fluid lifts the remains, dead cells, toxins and pathogens as it travels on the body. These waste products and harmful substances are often filtered in small organs called lymph nodes. The lymphatic blood vessels that bring lymphatic fluid to the lymph nodes are called afferent lymphatic blood vessels, while the blood vessels carry lymphatic fluid from the lymph nodes to re -enter the circulatory system.

sensory impulses are mediated towards the central nervous system by specialized cells calledafferent neurons. These neurons transmit external sensory stimuli to the brain by nerve pathways. The brain interprets and responds to them. Feelings such as heat, colds, pain and pressure are transmitted by afferent neurons, as well as different types of inputs from taste buds, eyes, ears and nose. Disorders of afferent neurons can cause the brain to misinterpret external stimuli, causing conditions such as hyperalgesia or acute sensitivity to pain, and phantom limb syndrome, causing pain in limbs that have been amputated or otherwise removed from the body. Effective neurons are nerve cells that transmit signals from the brain to the peripheral nervous system.
