Internal feeling, also known as somatosensory feeling, is a kind of feeling, which is relative to the feelings that reflect the external environment such as vision and hearing. Receptors are located in the body, reflecting the state of internal organs, body balance and self-condition, including motor feeling, balance feeling and visceral feeling.
Internal feeling: the feeling that the stimulus comes from the inside of the body and reflects the internal organs, body balance and one's own situation. Its receptors in visceral wall, peritoneum, pleura, joint capsule and vestibular organs transmit various chemical and physical stimuli such as the activities and changes of visceral organs, joints, muscles and vestibular organs to the center through afferent nerves, thus causing internal feelings such as hunger, thirst, fullness, nausea, pain and exercise balance.
One of them is similar to body surface sensations, such as pain, pulling and swelling. Another complex feeling, such as hunger, thirst and sexual feelings, is often formed by close contact with the limbic system of the brain. Inner feelings are usually inaccurate, sometimes difficult to distinguish, and some can't even arouse subjective feelings. Helps regulate visceral activity. Include motor sensation, balance sensation and visceral sensation.
