Feeling can be different things, such as touch, pressure, heat, cold or pain. There are special emotional bodies that make us feel. Some places on the body have many sensory bodies, such as the fingertips and lips. In other places, the sensory bodies are fewer, for example on the back.
Sensory bodies record emotion
You feel touch, pressure, heat and cold with the help of so-called sensory bodies. Each sensing body only receives information about a kind of sensation experience, such as cold or pressure. There are sensory bodies in the skin, inside the outer skin layer. The sensory bodies are also found in joints, muscles, tendons and in the internal organs.
Pain is recorded by nerve endings
Pain is not detected by sensory bodies, but by so-called free nerve endings. They are everywhere where you can feel pain, for example in the skin, muscles, joints and tendons. Free nerve endings are also found in internal organs, such as the heart, intestine and lung sac.
The emotion center is in the brain
The sensory bodies pass on the signals of contact to the brain. The signals are sent through the nerve strands to a part of the brain called the thalamus. The signals then pass through nerve fibers to the cortex. You become aware of the experience as the information reaches the sensory center in the brain.
Pain can act as a protection for the body
Pain is an uncomfortable feeling that you get from various types of severe impact that injures, or can damage the body. For example, it may be a stroke or severe pressure on the body or a stick. Pain can also be extremely hot or cold temperatures. The experience of pain acts as a protection, it is a signal that the body is exposed to injury.
The information about pain reaches several areas of the brain and initiates several reactions. You become aware of the pain and at the same time your heart rate increases and your blood pressure rises. In addition, you have a reflex that allows you to quickly pull away a body part from what is hurting the body part, for example if you put your hand on something warm and burn.
