Which part of the neuron is responsible for generating a nerve impulse? What is the name of the neuron fiber that carries impulses toward the cell body? What are autonomic ganglia? What kind of neurons are in the somatic nervous system?
The sensory system consists of neurons that sense a stimulus and initiate a nerve impulse. A stimulus can be in the form of energy like light, sound, heat, and chemical or electrical change. The nerve impulse is propagated by the electrical conducti...
It is the broad, rounded part of the neuron that contains thenucleus, abundant cytoplasm (neuroplasm) and otherorganelleslike mitochondria, endoplasmic reticulum, Golgi body etc. Axon It is a long tube-like structure thatcarries informationfrom thecell body tothenerve endings. Axon is covered by...
A bilipid layer surrounds the cell body of a neuron. The neuron has one axon, which typically carries impulses away from the cell body and may have many dendrites that carry information toward the cell body. • Retrograde transport up the axon mediates movement oftrophic substances, which pro...
Hereditary Spastic Paraplegia (HSP)andCharcot-Marie-Tooth Disease (CMT)areneurodegenerative diseases. They happen due to mutations in proteins like microtubules or neurofilaments in neurons. This leads tomuscle weakness, sensory loss, and neuron degeneration. ...

long projections, i.e. cilia, that protrude into the nasal cavity and contain the proteins that bind odorous substances and thus initiate nerve impulses to the brain. The conversion of odor into nerve impulses is called transduction and the newly discovered organelle contains only...
Neuron Impulse t is important to mention the Neuron as carrier impulses from the CNS to the periphery‚ the peripheral nerves in turn have the funsion to carry messages from one part of the organism to another‚ so we can understand the action of these drugs. They act in the prevention...
Neuron is a single nerve cell in the entire nervous system; which is electrically excitable cell that carries information after being processed via chemical or electrical signals. One of its key characteristics is that it does not undergo cell division. In addition, it maintains a voltage gradient...
