Protective. Sensory receptors are nociceptors. These receptors are free nerve endings and found in every body tissue except brain. Intense thermal, mechanical and chemical stimuli can activate this. Chemical e.g. prostaglandin, kinins, potassium ions released from injured tissue stimulate the nociceptors. WebJun 14, 2024 · A sensory neuron (sometimes referred to as an afferent neuron) is a nerve cell that detects and responds to external signals. Sensory neurons receive information via their receptors, which are part of the peripheral nervous system, and convert this information into electrical impulses. These impulses act as signals and are passed on to … protocol exploited in pcap
