WebApr 7, 2024 · Motor nerves transmit the signals from the CNS to the sensory organs and thus, help in initiating actions. These neurons are located at the ventral root ganglion of the spinal cord. Motor neurons consist of a long axon and multiple dendrons. They lack receptors. These neurons are also known as multipolar neurons. WebThe sensory neurons are the detectors of odorants, and they possess small proteins, or specific odorant receptors situated in the membrane of the sensory neurons. The part of the sensory neuron which is exposed to the environment is frequently enlarged by cilia and microvilli. There are three different types of sensory neurons that detect odorants in …
