Parasympathetic nervous system
it was the synapse
First order sensory neurons begin in the receptor, travel to dorsal/posterior gray horn of the spinal cord where they synapse with the second order sensory neurons.
interneurons also known as: ASSOCIATION NEURONS
A synapse is the junction or a point of close contact between two neurons.
The space between two neurons is called a synapse. It is a small gap where neurotransmitters are released from the axon terminal of one neuron, travel across the synapse, and bind to receptors on the dendrites of the neighboring neuron to transmit the signal. This process allows for the communication and transfer of information between neurons in the nervous system.

Ascending sensory neurons primarily terminate in the spinal cord and brainstem, where they synapse with second-order neurons. These second-order neurons then project to various brain regions, including the thalamus, which relays sensory information to the appropriate areas of the cerebral cortex for processing. The precise termination points can vary depending on the specific sensory pathway involved, such as the dorsal column-medial lemniscal pathway or the spinothalamic tract.
Instead of being processed in the brain, a reflex arc is processed in the vertebra, this allows for faster reflexes. Example of when the reflex arc is used is when a person touches a hot stove. The immediate response (which the reflex arc causes) is to pull away, but it doesn't really hurt till a few seconds after. This is because the brain was first bypassed, but has now had time to process what happened.
There are three types of neurons. 1.Sensory neurons: which carry impulses from the sense organs to the brain and spinal cord. 2.Motor neurons : which perform an opposite function to that of sensory neurons by carrying impulses from the brain and spinal cord to muscles and glands. 3. Inter neurons : which connect sensory and motor neurons and carry impulses between them.
synapse is that junction through which impulse can be transmitted from one neuron to another.
Yes, olfactory receptors synapse with mitral cells in the olfactory bulb. When odor molecules bind to olfactory receptors in the nasal epithelium, they activate sensory neurons that send signals to the olfactory bulb. In the olfactory bulb, these sensory neurons synapse with mitral cells, which then relay the olfactory information to higher brain regions for processing. This synaptic connection is crucial for the perception of smell.
