What happens at the level of the neuron starting with stimulus and ending with a response?
The stimulus is detected by the sensory receptor. The sensory receptor stimulates a sensory neuron. The sensory neuron transmits to the interneuron in the spinal cord. The interneuron stimulates a motor neuron. The motor neuron communicates to the muscle. The muscle(effector) then produces the response allowing the body to respond to the stimulus.
What happens If a nerve cell receives many IPSPs at the same time?
the neuron will be probably be inhibited from firing.
What is the effect of lidocaine on eliciting an action potential?
Ether prevents the action potential, by opening potassium ion pores, which allows the escape of potassium from the neurons, which results in hyper-polarization of the neuron, thus preventing the action potential from occurring.
What happens to neurotransmitters that fail to attach to a receptor site?
In a process called reuptake, they are reabsorbed by sending the neuron and recycled.
What happens when a neuron is polarized?
When a neuron is polarized, there is a difference in electrical charge between the inside and outside of the cell. This difference in charge is created by an uneven distribution of ions across the cell membrane. This polarization allows the neuron to generate and transmit electrical signals.
Effects of lidocaine on nerves?
it prevents sodium channels from opening which removes a neuron's resting membrane potential
What happens when a person loses neuron cells from a stroke?
It depends on which area of the brain or spinal cord is affected. The functions of that area will be altered or be stopped all together.
How does reflex occur?
This is what happens:a receptor detects a stimulus (change in the environment)a sensory neuron sends a signal to the relay neuronthe relay neuron sends the signal to the motor neuronthe motor neuron sends a signal to the affected partthe affected part produces a response
When you touch something hot, a neuron in your finger senses the temperature. Which happens first?
an action potential moves along the neuron
What is a part of a neuron affected by multiple sclerosis?
the myelin sheaths. The disease is classified as demyelinating , which is also known as the degeneration of the myelin structures in the neuron.
When you touch something hot a neuron in your senses the temperature. which happens first?
an action potential moves along the neuron
What happens when neurotransmitters communicate an excitatory message to the postsynaptic neuron?
When neurotransmitters communicate an inhibitory message to the postsynaptic neuron:
What is the Neuron function?
The function of a neuron is to transfer messages throughout the brain. These neurons are all attached and interpret everything that happens.
Which part of a neuron would probably be affected most by lead poisoning?
The Synaptic knob
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 happens during an action potential in a neuron?
During an action potential in a neuron, there is a rapid change in electrical charge across the cell membrane. This change allows for the transmission of signals along the neuron.
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.
