Classification of sensory neuron
WebMay 20, 2024 · The spinal cord, as a key part of our body’s central nervous system, contains millions of neurons that actively convey sensory and motor (movement) information to and from the brain. Scientists have long sorted these spinal neurons into what they call “cardinal” classes, a classification system based primarily on the developmental origin ...

WebApr 12, 2024 · Histamine. Histamine is an excitatory neurotransmitter produced by neurons of the hypothalamus, cells of the stomach mucosa, mast cells, and basophils in the blood. In the central nervous system, it is important for wakefulness, blood pressure, pain, and sexual behavior. In the stomach, it increases the acidity. 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 … See more Neurons are cells of the nervous system that can transmit electrical impulses to facilitate communications between the brain and the rest of the body.
