Cutaneous senses and their receptors
WebThe sense of touch makes you aware of pain, temperature, pressure, vibration, and body position. Skin, muscles, tendons, joints, and internal organs have nerve endings (receptors) that detect these sensations. Some receptors give the brain information about the position and condition of internal organs. WebDescribe the topographical distribution of somatosensory receptors. Figure 1.
