Neurons are stimulated by What?
Neurons are stimulated by various factors, primarily through the release of neurotransmitters that bind to receptors on their surface. These neurotransmitters can be released from other neurons or sensory cells in response to external stimuli, such as light, sound, or touch. Additionally, electrical impulses can also stimulate neurons, leading to the generation of action potentials that propagate signals throughout the nervous system. Overall, the stimulation of neurons is crucial for communication within the nervous system and the processing of information.
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).
What supports neurons supplying them with nutrients and carrying away their waste products?
Supporting cells called glial cells provide nutrients to neurons and help remove waste products. Blood vessels also play a role by delivering oxygen and nutrients to neurons and removing metabolic waste. This collective support system ensures the proper functioning and survival of neurons in the brain.
When you swat a fly which type of neuron stimulates your arm to move?
When you swat a fly, motor neurons are stimulated to activate the muscles in your arm, causing it to move. These motor neurons transmit signals from the central nervous system to the muscles, facilitating coordinated movement. The process typically involves sensory neurons detecting the fly's presence and interneurons processing that information before relaying commands to the motor neurons.
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.
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 supports neurons supplying them with nutrients and carrying away their waste products?

Blood vessels also play a role by delivering oxygen and nutrients to neurons and removing metabolic waste.

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.
