Sensory Neurons
are responsible for bringing information from sensory receptors
Sensory neurons are specialized nerve cells that transmit information from sensory receptors located in various parts of the body to the spinal cord and brain. They allow us to perceive and respond to different stimuli, such as changes in temperature, pressure, light, sound, taste and smell.
These neurons have a unique structure with a long axon that extends from the receptor to the spinal cord or brain. The cell body of the sensory neuron is located in the dorsal root ganglia, which is a cluster of nerve cell bodies outside the spinal cord. The dendrites of the sensory neuron receive signals from sensory receptors, while the axon carries the signal to the central nervous system.
Sensory neurons are classified into different types based on the type of stimulus they respond to. For example, photoreceptors in the eye respond to light, while mechanoreceptors in the skin respond to pressure or touch. Other types of sensory neurons include chemoreceptors, thermoreceptors, and nociceptors which respond to chemical, temperature and pain stimuli respectively.
In summary, sensory neurons are essential for our ability to sense and respond to changes in our environment. They play a critical role in our perception, emotion, and decision-making processes.
