Nociceptors are a group of cells that senses painful stimuli and sends these nerve signals to the brain and the spinal cord. It has been documented that both mammals and non-mammals have nociceptors that respond to thermal, mechanical or chemical stresses.

Detecting painful stimuli
Nociceptors are also known as pain receptors. These specialized nerve cells detect potentially damaging stimuli and send signals to the brain warning of potential tissue damage, resulting in the sensation of pain.
The brain itself does not have nociceptors. This means the brain can't feel pain directly, but it can perceive pain signals from other parts of the body.

True
Nociceptors are located throughout the body, particularly in the skin, joints, and internal organs. These specialized nerve endings are responsible for detecting potentially harmful stimuli, such as temperature, pressure, or chemicals, and signaling the brain to perceive pain.
Mechanical nociceptors are sensory receptors that respond to physical damage or potential harm to the body, such as pressure, stretching, or cutting. When these nociceptors are activated, they send signals to the brain indicating tissue damage, which is perceived as pain. This helps the body to identify and respond to potential threats, promoting survival and protection.
Nociceptors (pain receptors) adapt most slowly compared to other types of receptors. They continue to fire in response to a persistent stimulus and do not adapt or desensitize as quickly as other sensory receptors.
somatic
Nociceptors are sensitive to potentially damaging stimuli such as mechanical, chemical, or thermal stimuli. They detect noxious stimuli and convert them into electrical signals that are transmitted to the brain, where pain sensation is perceived.
