A sensory nerve receptor that responds to pain.
free sensory nerve ending responsible for pain reception.
Receptor responding to stimuli that produce pain.
Definition: Nociceptors are a specific subset of peripheral sensory organs which respond to noxious stimuli. A mechanoreceptors and C-polymodal nociceptors are the two main classes of cutaneous nociceptors. The sensory quality of pain evoked by activation of A-fibers is generally described as 'pricking', whereas that evoked by activation of C-fibers is generally described as 'burning'.
a pain receptor
a receptor for stimuli that are painful
a sensory receptor that responds only after a high level of stimuli or a level enough to hurt the individual
a sensory receptor thatresponds to pain
a peripheral nerve organ or mechanism for the reception and transmission of painful or injurious stimuli.
a subgroup of sensory neurons that initiate the transmission of information, regarding tissue damage, to the brain.
A specialized nerve ending that senses painful or harmful sensations and transmits then to a nerve.
A structure that recognises signals from inside or outside the body, including temperature, pressure and chemicals. When activated, it sends signals to nerve cells, which carry the messages to the central nervous system (the spinal cord and brain).
A type of nerve receptor that activate when there's a painful stimulus.
A sensory receptor responding to potentially harmful stimuli; produces a sensation of pain.
A free nerve ending which detects noxious stimuli - chemical, mechanical and thermal. When tissue is damaged a variety of chemicals are released or synthesised, including histamine, potassium ions, bradykinin and prostaglandins. The body's own chemicals thereby stimulate these receptors in response to actual or potential damage, and this can be perceived as pain.
Sensory ending responding to noxious stimuli and eliciting the sensation of pain
A sensory neuron that is activated by stimuli that damage tissue, leading to the sensation of pain.
a free (naked) nerve ending that detects pain
A nociceptor is a sensory receptor that sends signals that cause the perception of pain in response to potentially damaging stimulus. Nociceptors are the nerve endings responsible for nociception, one of the two types of persistent pain (the other, neuropathic pain, occurs when nerves in the central or peripheral nervous system are damaged). When they are activated, nociceptors can trigger a reflex.
