When someone taps your shoulder, sensory neurons in the skin detect the pressure and convert that mechanical stimulus into an electrical signal. These signals are transmitted through the peripheral nervous system to the spinal cord and then relayed to the brain for processing. Specifically, the action involves mechanoreceptors, which are specialized sensory neurons responsive to touch, pressure, and vibration. Ultimately, this triggers a response in the brain, allowing you to perceive the tap.

What goes on when an action potential is transferred from one neuron to the next through a synapse?
When an action potential reaches the axon terminal of the presynaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, leading to changes in its membrane potential. This process either excites or inhibits the postsynaptic neuron, depending on the neurotransmitter and receptor type involved.
The axon of each motor neuron has numerous endings are called what?
The tip of a neuron's axon culminates in several endings call terminal buttons. When an action potential is conducted down the axon, this is where it goes.
Can a first order sensory neuron sometimes be a sensory receptor?
The first order sensory neuron can sometimes be a sensory receptor because it is what sends the signal to the brain from the receptor. The second order goes from the brainstem to the thalamus.
What is the pathway called that signals travel along during a reflex?
Sensory neurons which trigger reflexes are called nociceptive neurons. After entering the dorsal root of the spinal cord, the nociceptive neuron branches into two terminals: one terminal synapses with an interneuron - a localised neuron which is located entirely within the grey matter of the spinal cord, and this in turn synapses with a motor neuron which then triggers the fast reflex action. The reflex is initiated solely within the spinal cord & doesn't involve the brain at all, but at the same time, the second branch of the nociceptive neuron synapses with a sensory neuron which goes to the brain; the brain then registers the sensation of pain, and can also initiate further motor action if necessary.
What action do you take if chemical goes to your eyes?
simply i will rinse it with water or get my eyes and cleaned it
What happens to the neuron after an action potential is fired?
After an action potential is fired, the neuron goes through a refractory period where it cannot fire another action potential immediately. During this time, the neuron resets its electrical charge and prepares for the next signal.
What goes on when an action potential is transferred from one neuron to the next through a synapse?
When an action potential reaches the axon terminal of the presynaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, leading to changes in its membrane potential. This process either excites or inhibits the postsynaptic neuron, depending on the neurotransmitter and receptor type involved.
An efferent neuron carries impulses in the direction opposite of?
opposite of an afferent neuron. an efferent neuron goes from the central nervous system to the organ in the body that will perform the required action.
Why are reflex actions very fast?
The impulse in a reflex action goes directly from the sensory neuron to the inter neuron to the spinal cord, which allows for faster actions.
What is the verb in this sentence Hamed goes away into the desert?
"goes" as this the the word of action that tells us what someone is doing.
Why is a neuron called an interneuron?
A neuron is called a inter-neuron because that specific neuron takes impulse from one neuron to a next neuron. For example your sensory neuron sends a impulse that you had felt a hot object. It goes through the spine to a inter-neuron to a motor neuron (this processes is called a reflex). Then the motor neuron tells your muscles in your hand to move
The axon of each motor neuron has numerous endings are called what?
The tip of a neuron's axon culminates in several endings call terminal buttons. When an action potential is conducted down the axon, this is where it goes.
What is the mob act?
Mobs had an act, that when they said something it either goes to action or they will have a terrible reaction with that special someone.
How many times can a neuron fire per second?
Depends on the function of the neuron, the range goes from once per sec to 1000 pulses per sec.
How does a neuron sends messages to a cell?
I think the brain makes a shock and goes down to your spinal cord and goes to the cell
How does a message travel through a single neuron?
When a message gets sent to a neuron from the dendrite it goes through the cell body to the tip of the dendrite where it leaps to the next dendrite.
What is a hemerus bone?
the one that goes from shoulder to elbow
