SENSORY
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.
The distal ends of sensory neurons are called dendrites. Dendrites receive incoming signals or stimuli from the environment through sensory receptors, such as in the skin, eyes, ears, and other sensory organs. These signals are then transmitted to the cell body of the neuron and eventually to the central nervous system for processing.
Chemoreceptors: Detect chemical stimuli such as taste and smell. Photoreceptors: Respond to light stimuli in the eyes, allowing us to see. Mechanoreceptors: Sense mechanical stimuli like pressure and touch, found in the skin and inner ear.
The eyes, nose, skin and tongue HAVE sensory receptors.

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.
The nerve cells connected in the eyes, nose, skin, and tongue are called sensory neurons. These specialized cells are responsible for detecting and transmitting sensory information from these organs to the brain for processing. Each type of sensory neuron is tuned to respond to specific types of stimuli, such as light (in the eyes), odors (in the nose), touch (in the skin), and taste (in the tongue).

pain receptors
Merkel cells, located in the epidermis of the skin, are responsible for sensing light touch and pressure. They are connected to nerve endings and help transmit information about pressure stimuli to the brain.
