Difference Between Sensory and Motor Neurons
Parameters |
Sensory Neurons |
Motor Neurons |
Definition |
Sensory neurons are a type of neuron that transmits sensory information from sensory organs and receptors to the central nervous system. |
Motor neurons are a type of neuron that transmit signals from the CNS to muscles and glands, controlling voluntary and involuntary movements, and regulating physiological processes. |
Types of neuron morphology |
Sensory neurons are typically unipolar. |
Motor neurons are typically multipolar neurons. |
Location of Neurons |
Sensory neurons are found in the eyes, ears, tongue, skin, and nose. |
Motor neurons are found in muscles and glands. |
Functions |
Sensory neurons detect and transmit sensory stimuli to the CNS. |
Motor neurons receive signals from the CNS and initiate muscle contractions or control involuntary functions. |
Location of cell bodies |
The cell bodies of sensory neurons are located in specialized structures called ganglia, which are found outside the CNS. |
The cell bodies of motor neurons are typically located inside the CNS, specifically within the brainstem and the spinal cord. |
Difference Between Sensory And Motor Neurons
Sensory neurons and Motor neurons are essential components of the nervous system, each playing a distinct role in sensory perception and motor control. Sensory neurons detect sensory stimuli from the environment and transmit signals to the central nervous system, while motor neurons receive signals from the central nervous system and initiate muscle contractions.
So the question arises: are both the same? No, sensory neurons and motor neurons are not the same. They are distinct types of neurons that serve different functions within the nervous system.
