The neurological law that deals with light touch is called the Arndt-Schultz law.
The four main types of nerve endings found in the skin are free nerve endings (responsible for pain and temperature sensation), Merkel discs (responsible for light touch and pressure), Meissner's corpuscles (responsible for light touch), and Pacinian corpuscles (responsible for deep pressure and vibration sensation).
Skin nerve fibers play a crucial role in the sensation of touch and pain. They are responsible for transmitting signals from the skin to the brain, allowing us to feel sensations such as pressure, temperature, and pain. Different types of nerve fibers respond to different stimuli, with some specialized for detecting light touch and others for detecting pain. When these nerve fibers are activated by stimuli, they send signals to the brain, which interprets the information and allows us to perceive and respond to touch and pain.
Skin nerve endings are specialized receptors that detect various stimuli, such as pressure, temperature, and vibration. When these nerve endings are stimulated by touch, they send signals to the brain, which interprets the information and creates the sensation of touch. In this way, skin nerve endings play a crucial role in our ability to feel and perceive the world around us through touch.
electrical synapses
When you touch a nerve, it can cause pain, tingling, numbness, or weakness in the area connected to that nerve. This can affect the body by disrupting normal sensation and movement, potentially leading to temporary or long-term issues depending on the severity of the nerve damage.
The nerve impulse from your foot to your leg is called a sensory nerve signal or proprioceptive feedback. It helps transmit information about sensations such as touch, pressure, and position to the brain.
touch
Flash! - The impulse is a jump of electricity from one neuron to the next via the dendrites. It happens in a millisecond of time so we are not even aware of it. Touch an ice cube with your finger; the signal goes from the finger to the brain and back that we get the immediate sense that the ice cube is cold.

touch-stimuli-receptor-impulse
A nerve stimulus is a signal or impulse that is transmitted along a nerve fiber, triggering a response in the body. This stimulus can be initiated by various factors such as touch, temperature, or pressure, and is essential for the communication between different parts of the nervous system.
Peritricial nerve endings, also known as peritrichial receptors, are specialized sensory nerve endings that wrap around the base of hair follicles in the skin. They are sensitive to mechanical stimuli, such as touch or movement of hair, and play a role in the sensation of light touch. These nerve endings help the nervous system detect changes in the environment, contributing to the sense of touch and providing feedback about external stimuli.
Tactile corpuscle are the nerve endings in the skin that respond to the lightest touch. They are most concentrated on the fingertips and lips.
Skin nerve fibers play a crucial role in the sensation of touch and pain. They are responsible for transmitting signals from the skin to the brain, allowing us to feel sensations such as pressure, temperature, and pain. Different types of nerve fibers respond to different stimuli, with some specialized for detecting light touch and others for detecting pain. When these nerve fibers are activated by stimuli, they send signals to the brain, which interprets the information and allows us to perceive and respond to touch and pain.
The main nerve related to the sense of touch is the somatosensory nerve, which includes sensory nerves such as the median, ulnar, radial, and the dermatomes of the spinal nerves. These nerves transmit touch signals from the skin to the brain for processing.

Skin nerve endings are specialized receptors that detect various stimuli, such as pressure, temperature, and vibration. When these nerve endings are stimulated by touch, they send signals to the brain, which interprets the information and creates the sensation of touch. In this way, skin nerve endings play a crucial role in our ability to feel and perceive the world around us through touch.
