What neuron picks up a stimulus?
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.
What changes occur in a neuron as it carries out its normal functions?

How does transmission occur in the Central Nervous System?
Transmission of data occurs within our Central nervous system by means of Neurons.there are mainly three types of neuronsSensory neuronsmotor neuronsinter neurons
Can reflex action happens if the sensory neuron is cut but the motor neuron is not cut?
No, reflex action cannot occur if the sensory neuron is cut, even if the motor neuron remains intact. Reflex actions rely on the sensory neuron to detect a stimulus and transmit that information to the spinal cord, where it is processed and relayed to the motor neuron to initiate a response. If the sensory neuron is damaged, the signal cannot reach the spinal cord, preventing the reflex arc from completing.
What picks up a stimulus from the environment and changes it into a nerve?
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.
Where do most local potentials happen?
Local potentials typically occur in the dendrites and cell body of a neuron. They involve small changes in membrane potential that do not reach the threshold for generating an action potential. These local changes in potential allow for signal integration and processing in the neuron.
What neuron picks up a stimulus?
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.
What is local graded potential?
Local graded potentials are small changes in membrane potential that occur in response to neurotransmitter binding to ligand-gated ion channels on the post-synaptic neuron. These potentials can summate and affect the likelihood that an action potential will be generated in the neuron. They are also referred to as synaptic potentials.
Why does hyperpolarization cause a spike to occur?
Hyperpolarization causes a spike to occur because it increases the difference in electrical charge between the inside and outside of a neuron, making it more likely for the neuron to generate an action potential or spike.
During an action potential, what happens to the neuron's electrical charge?
During an action potential, the neuron's electrical charge rapidly changes from negative to positive, allowing for the transmission of signals along the neuron.
Where does synapses occur in the spinal cord?
Cell body of sensory neuron - in dorsal root ganglion. Cell body of motor neuron - in anterior gray horn.

What happens when a substance gets into a neuron?
When a substance enters a neuron, it can bind to receptor sites on the neuron's membrane, triggering a cascade of events within the neuron. This can lead to changes in the neuron's electrical activity, release of neurotransmitters, or alterations in gene expression, ultimately affecting the neuron's function.
Neurotransmitters find their way to and subsequently trigger firing of that neuron?
Excitatory neurotransmitter
Can reflex action happens if the sensory neuron is cut but the motor neuron is not cut?
No, reflex action cannot occur if the sensory neuron is cut, even if the motor neuron remains intact. Reflex actions rely on the sensory neuron to detect a stimulus and transmit that information to the spinal cord, where it is processed and relayed to the motor neuron to initiate a response. If the sensory neuron is damaged, the signal cannot reach the spinal cord, preventing the reflex arc from completing.
What was Excitation and Inhibition about?
Excitation and Inhibition occur in the neurons. Excitation is when a neuron becomes depolarized and fires an action potential. Inhibition is when a neuron becomes hyperpolarized preventing it from firing an action potential.
