Cutaneous Sensations
In the skin, neurons that detect stimuli are called mechanoreceptors for touch, nociceptors for pain, and thermoreceptors for temperature. In the eyes, neurons that detect light stimuli are called photoreceptors, specifically rods and cones located in the retina.
The neurons in the brain and else where do not normally regenerate. Skin cells do regenerate.
sensory neurons
Somatic sensory neurons detect stimuli from the skin, muscles, and joints. Visceral sensory neurons detect stimuli from internal organs such as the heart, lungs, and intestines. Both types of neurons transmit sensory information to the central nervous system for processing.
Yes, neurons with small receptive fields are typically found in areas of the skin that are most sensitive, such as the fingertips and lips. These regions require fine discrimination and precise sensory information, which is enabled by having smaller receptive fields on the neurons.
Sensory neurons in the skin play a crucial role in detecting and transmitting various sensory information such as touch, temperature, and pain to the brain. This helps us navigate our environment, feel pain to protect ourselves from harm, and maintain a sense of touch in our daily activities.
Nociceptors are the neurons in the skin that are responsible for detecting pain. They are specialized sensory receptors that respond to potentially damaging stimuli by sending signals to the brain, alerting the body to the presence of tissue-damaging stimuli like heat, pressure, or chemicals.
An increase in temperature can stimulate sensory neurons in the skin, providing feedback to the brain about the external environment. This can trigger responses such as sweating or shivering to help regulate body temperature.
