Once a sympathetic preganglionic axon reaches a trunk ganglion what can it do?
it can 1. synapse with a ganglionic neuron in the same trunk ganglion, 2. ascend or descend the sympathetic trunk to synapse in another trunk ganglion or 3. pass through the trunk ganglion and emerge from the sympathetic trunk without synapsing The answer: Synapse with a parasympathetic neuron in the same trunk ganglion
What are the 3 things that sympathetic preganglionic axon reaches a trunk ganglion?
Sympathetic preganglionic axons reach a trunk ganglion through three key pathways: (1) they may synapse directly with postganglionic neurons in the ganglion, (2) they can ascend or descend within the sympathetic trunk to synapse at a different ganglion, or (3) they may pass through the ganglion without synapsing and continue to target organs via splanchnic nerves. These pathways enable the sympathetic nervous system to coordinate responses throughout the body effectively.
The preganglionic fibers that connect a spinal nerve with an autonomic ganglion in the thoracic and lumbar region of the spinal cord and carries visceral motor fibers that are myelinated form the?
The preganglionic fibers that connect a spinal nerve with an autonomic ganglion in the thoracic and lumbar regions of the spinal cord are part of the sympathetic nervous system. These fibers originate from the lateral horns of the spinal cord and are myelinated, allowing for rapid signal transmission. They typically travel through the ventral roots and enter the sympathetic chain or prevertebral ganglia to synapse with postganglionic neurons.
Who do preganglionic neurons synapse with?
Preganglionic neurons synapse with postganglionic neurons in the autonomic nervous system. These synapses occur in ganglia, which are clusters of nerve cell bodies located outside the central nervous system. In the sympathetic division, preganglionic neurons typically synapse in sympathetic ganglia near the spinal cord, while in the parasympathetic division, they synapse in ganglia located close to or within the target organs. This synaptic connection is crucial for transmitting signals that regulate involuntary bodily functions.
How does nicotine effect cells?
Nicotine is a Sympathetic drug when it acts on synapse it has its Sympathomimetic action and it activates the neurons.
What is the junction point between neurons?
A synapse is the junction or a point of close contact between two neurons.
Neurons connect together at a?
Synapse Synapse
What is the connection between neurons called?
A synapse.
What is the name of the region where two neurons are in done contact is known as?
synapse is that junction through which impulse can be transmitted from one neuron to another.
In a three neuron reflex arc the afferent neurons synapse with?
In a three neuron reflex arc, the afferent neurons synapse with interneurons in the spinal cord or brainstem. The interneurons then synapse with efferent neurons which transmit the signal to the effector organ to initiate a response.
The site of intercellular communication between neurons is the?
the synapse
Is the point at which two neurons meet?
Neurons meet at the synapse.
