What else can I help you with?
What sympathetic ganglion distributes postganglionic neuronal processes to the kidneys?
The renal plexus is the sympathetic ganglion that distributes postganglionic neuronal processes to the kidneys.
What parasympathetic ganglion sends postganglionic fibers to the sublingual and submandibular salivary glands?
The submandibular ganglion sends postganglionic fibers to the sublingual and submandibular salivary glands.
Is the adrenal medulla a misplaced sympathetic ganglion?
The adrenal medulla has many similarities with post-ganglionic sympathetic neurons, they release catecholamine because medullary cells are derived from the neural crest and, as such, are simply modified neurons. The adrenal gland releases epinephrine, norepinephrine and dopamine in response to neural not hormonal signals just like postganglionic neurons. The most significant different between adrenal medulla cells and true postganglionic sympathetic neurons is the absence of axons. The neurotrasmitter has become a hormone and is released into the blood.
Which Postganglionic fibers emerging from pterygopalatine ganglion of trigeminal nerve?
Postganglionic fibers emerging from the pterygopalatine ganglion of the trigeminal nerve innervate the lacrimal gland to stimulate tear production and the mucous glands in the nasal cavity. These fibers are involved in regulating the secretion of tears and mucus in the eye and nose, helping to maintain the health and moisture of these structures.
Are there bipolar cells in the ciliary ganglion?
No, bipolar cells are a type of neuron found in the retina of the eye, not in the ciliary ganglion. The ciliary ganglion primarily contains postganglionic parasympathetic neurons that innervate the muscles controlling the shape of the lens in the eye.
What sympathetic ganglion distributes postganglionic neuronal processes to the kidneys?
The renal plexus is the sympathetic ganglion that distributes postganglionic neuronal processes to the kidneys.
The postganglionic sympathetic fiber originates from?
The postganglionic sympathetic fiber originates from PNS within a ganglion
Do all visceral motor neurons synapse in a sympathetic ganglion?
No; some axons synapse in nearby autonomic ganglion. postganglionic fibers travel along either sympathetic nerves or rejoin at the spinal nerve.
What parasympathetic ganglion sends postganglionic fibers to the sublingual and submandibular salivary glands?
The submandibular ganglion sends postganglionic fibers to the sublingual and submandibular salivary glands.
Postganglionic fibers that innervate targets in the body wall or thoracic cavity originate on neurons within?
Postganglionic fibers that innervate targets in the body wall or thoracic cavity originate on neurons within the sympathetic chain ganglia (paravertebral ganglia) or prevertebral ganglia (e.g., celiac ganglion). These ganglia are part of the sympathetic division of the autonomic nervous system and play a role in coordinating the body's fight-or-flight responses.
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
Is the adrenal medulla a misplaced sympathetic ganglion?

What is the celiac ganglion?
The celiac ganglion is part of the prevertrebral ganglions. It is the ganglion that is part of the sympathetic nervous system that innervates the digestive system.
Which Postganglionic fibers emerging from pterygopalatine ganglion of trigeminal nerve?
Postganglionic fibers emerging from the pterygopalatine ganglion of the trigeminal nerve innervate the lacrimal gland to stimulate tear production and the mucous glands in the nasal cavity. These fibers are involved in regulating the secretion of tears and mucus in the eye and nose, helping to maintain the health and moisture of these structures.
What are the differences between preganglionic and postganglionic neurons?
You have a really good question. Studying the nervous system can be overwhelming and quit confusing. Preganglionic Neurons come from the CNS to the Ganglion ( mass of neuron cell bodies and dendrites) and Postganglionic neurons leave the ganglion and head toward the effector organ ( smooth muscle, glands, etc..).
Are there bipolar cells in the ciliary ganglion?
No, bipolar cells are a type of neuron found in the retina of the eye, not in the ciliary ganglion. The ciliary ganglion primarily contains postganglionic parasympathetic neurons that innervate the muscles controlling the shape of the lens in the eye.
How do you account for the fact that the third thoracic ganglion is larger than the others?
Thoracic ganglia are part of the sympathetic system. There are twelve different ganglion, and some are larger than others.
