Dendrite to soma to axon ;)
A message travels through a neuron in the following order: dendrites receive the signal, the signal is passed through the cell body (soma), travels down the axon, and finally reaches the synaptic terminals where it is transmitted to the next neuron.
What_is_the_process_of_a_nervous_impulse_traveling_through_a_neuron
The reflex arc includes the sensory neuron (sensory intake) to the motor neuron (motor response). This two neuron arc is the fastest. Many times an interneuron at the level of the spinal cord is involved. It passes information to the brain more slowly. It is like an "incident report".
The flow of information across nerve cells is called a nerve impulse in which the axons of the cell must depolarize, repolarize and go through a refractory period before reaching the resting potential. At this point, another impulse can occur.
The second-order neuron of the spinothalamic system terminates in the thalamus, specifically the ventral posterolateral nucleus. From here, the information is relayed to the somatosensory cortex for further processing and perception of pain and temperature.
I am doing a project and we need to pretend that we are a neuron transmission in a human body. Trace you life from the sensory receptor to the central nervous system and back to the motor neuron. Explain how you are sending information about stimulus to the brain and returning to the effector neuron in order for the person to have a reaction to the stimulus. I just need to know the pathway if the stimulus is sent from the eye to the legs. Like if a person is running and sees something that he/she needs to jump over. Thank you in advance for the help, as I am not quite sure of the pathway, and your help is greatly appreciated. EX. eye to sensory neuron, etc.
A second order neuron is the 2nd neuron to carry an order. The order could be a sensory stimulus or a motor stimulus. For e.g. in order to move a muscle, the order for that muscle to contract starts at the cerebral cortex in the somatomotor area. That is the first order neuron. The axon of the 1st order neuron will synapse with the 2nd order neuron at the level of the brain stem, which commonly decussate (crosses over) to the opposite side. In turn, the axon of the 2nd order neuron will descend along the spinal cord tracts where it will synapse with the 3rd order neuron. The 3rd order neuron is located in the ventral horn of the spinal cord, which will exit with the spinal nerve to supply the muscle.
A molecule is many order of magnitude smaller than a neuron. A neuron is made of molecules not the other way around.
When transmitting a message, a signal travels through the neuron until the cell ends at the terminal. In order to propagate the signal to the next neuron chemical messengers (neurotransmitters) are released into the inter-neuronal space (synapse). This triggers signal initiation in the second neuron.
The Right to Information Act was passed in June 2005 in India in order to set up a structure whereby citizens can request (and receive) information in a consistent manner and a reasonable amount of time.

Afferent neurons receive and transmit impulses to the CNS.
