How do the types of neurons found in the CNS and pns differ in their function?
Sensory (afferent) neurons conduct sensory information toward the CNS.The brain and spinal cord contain interneurons. These receive information and if they are sufficiently stimulated, they stimulate other neurons.Motor neurons (efferent neurons) send information from interneurons to muscle or gland cells (effectors).
Write to basic properties of Nuron?
Excitability / irritability: This means they can be stimulated to produce an impulse (action potential) – a tiny electrical current. Conductivity: This means neurons are also able to transfer an impulse along the full length of their axons and then on to other neurons, muscles or glands.
Neurons send messages in the form of what signals?
Neurons send messages in the form of electrical signals called action potentials. When a neuron is stimulated, it generates an action potential that travels along its axon to communicate with other neurons or target cells. This electrical signal can trigger the release of neurotransmitters, which are chemical signals that transmit the message across the synapse to the next neuron.
When the neuron is sussiciently stimulated this process and triggers the action potential?
When a neuron is sufficiently stimulated, it depolarizes, allowing sodium ions to rush into the cell, triggering an action potential. The action potential travels down the length of the neuron, causing the release of neurotransmitters at the synapse and facilitating communication with other neurons.
What changes occur in the neuron?
In response to stimuli, neurons may undergo changes in their membrane potential, leading to the generation and propagation of electrical impulses called action potentials. Additionally, synaptic connections between neurons can be strengthened or weakened through processes like long-term potentiation and depression, which play a role in learning and memory.
What happen when receptor is stimulated?
When a receptor is stimulated it triggers impulses in other neurons....hope this was helpful and correct
Why does the nerve action potential increase slightly when you add 1.0 V to the threshold voltage and stimulate nerve?
The action potential increases slightly because more neurons are being stimulated.
What stimualtes muscles?
Muscles are stimulated by signals from nerve cells called motor neurons
When several neurons are stimulated equally which one will fire first?
The neuron with the lowest threshold potential will fire first when several neurons are stimulated equally. Threshold potential is the minimum level of depolarization needed to trigger an action potential in a neuron. Neurons with lower threshold potentials are more excitable and will fire before neurons with higher threshold potentials.
What does Long-term potentiation involve?
The strength of the connection between two neurons is increased when they are simultaneously stimulated.
What is the difference between presynaptic and postsynaptic neurons?
Presynaptic neurons release the neurotransmitter in response to an action potential. Postsynaptic neurons receive the neurotransmitter (and can however become presynaptic to the next nerve cell, if the neurotransmitter has stimulated the cell enough).
When neuron stimulated enough it?
When a neuron is stimulated enough, it reaches its threshold potential and fires an action potential. This action potential travels down the axon of the neuron, allowing for the communication of signals to other neurons or cells.

When receiving a massage what neurons are affected?
Any topical neuron can be stimulated through the pressure (whether it be little or a lot) of touch. In response to a topical neuron being stimulated it can cause a chain reaction effect to the neurological mapping of the area being affected.
What is an unstimulated neuron?
An unstimulated neuron is a nerve cell that is not currently transmitting signals. It is in a resting state, with a stable membrane potential, and is not actively firing action potentials or sending messages to other neurons.
