How does the structure of a motor neuron differ from a sensory neuron?
Motor neurons have a cell body, short dendrites and a long axon. Their function is to conduct impulses to an effector (muscle or gland). Sensory neurons, on the other hand, have a cell body, long dendrites and a short axon. Their function is to conduct impulses to the Central Nervous System.
Are sensory and motor neurons similar?
They are located in the ventral root ganglion of the spinal cord. The main difference between sensory and motor neuron is their function and structure….Related Links:

What structure is found between sensory and motor neurons?
As the name suggests, interneurons are the ones in between – they connect spinal motor and sensory neurons. As well as transferring signals between sensory and motor neurons, interneurons can also communicate with each other, forming circuits of various complexity.
What is the difference between a sensory nerve and a motor nerve?
Structure of a Nerve A nerve contains bundles of nerve fibers, either axons or dendrites, surrounded by connective tissue. Sensory nerves contain only afferent fibers, long dendrites of sensory neurons. Motor nerves have only efferent fibers, long axons of motor neurons.
How does the structure of a sensory neuron differ from the structure of the other two types of neurons?
Motor neurons tend to have a multipolar morphology, with a single axon and many dendrites. However, sensory neurons are usually pseudounipolar. Additionally, motor neurons have short dendrites and long axons, whereas sensory neurons have long dendrites and short axons.
The structure of a motor neuron can be categorized into three components: the soma, the axon, and the dendrites. The soma is the cell body where the nucleus lies, and which controls the cells and is also where proteins are produced to maintain the functioning of the neuron.
Which accurately describes motor and sensory pathways?
Which accurately describes sensory and motor pathways? Sensory pathways terminate in the brain, and motor pathways terminate at effectors.
What are the similarities and differences between the sensory neurons and the motor neurons of the peripheral nervous system?
Explanation: Sensory neurons and motor neurons; 1)sensory neurons only bears sense from body part to brain where as motor one’s flow sense from brain to body. 2)The sensory neurons has short axon whereas the motor neurons has long axon.
What are sensory neurons also known as?
Afferent neurons – also called sensory neurons – are the nerves responsible for sensing a stimulus. Then, they send information about that stimulus to your central nervous system. These neurons are located in the central nervous system (the brain and spinal cord).
Are sensory neurons unipolar?
Unipolar cells are exclusively sensory neurons and have two unique characteristics. First, their dendrites are receiving sensory information, sometimes directly from the stimulus itself. Secondly, the cell bodies of unipolar neurons are always found in ganglia.
Are sensory neurons in the CNS or PNS?
The central nervous system (CNS) consists of the brain and the spinal cord. The peripheral nervous system (PNS), which consists of the neurons and parts of neurons found outside of the CNS, includes sensory neurons and motor neurons.
What is the difference between the sensory and motor neurons?
The main difference between sensory and motor neurons is that sensory neurons carry signals from receptors to the spinal cord and brain whereas motor neurons carry signals from the central nervous system to effector organs.
How do sensory nervous and motor neurons differ?
The key difference between sensory and motor neurons is that the sensory neurons are the neurons that carry information from sense organs to the central nervous system while motor neurons are the neurons that carry information from the central nervous system to the muscle cells .
Does mixed nerve contain both sensory and motor neurons?
Mixed cranial nerves are the cranial nerves that contain sensory and motor nerve fibers . There are four of such nerves in our peripheral nervous system ; Trigeminal nerve (CN V) Facial nerve (CN VII)
What transmits impulse between sensory and motor neurons?
Interneurons (AKA relay neurons) form connections between the sensory and motor neurons. These neurons complete the circuit between sensory neuron input and motor neuron response. Draw the structure of a motor neuron.
