The submandibular ganglion sends postganglionic fibers to the sublingual and submandibular salivary glands.
The renal plexus is the sympathetic ganglion that distributes postganglionic neuronal processes to the kidneys.
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.
The sympathetic ganglion that distributes postganglionic neuron processes to the kidneys and gonads is the prevertebral ganglion called the superior mesenteric ganglion. It is located in the abdominal cavity, anterior to the aorta and just below the origin of the superior mesenteric artery.
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.
The component of the ANS that is characterized by ganglion located in or near effector organs is called the parasympathetic nervous system. The ganglia of the parasympathetic nervous system are located close to or within the target organs they innervate, allowing for direct and localized control of bodily functions. This branch of the autonomic nervous system is responsible for promoting rest, digestion, and relaxation.

Parasympathetic innervation to the salivary glands is carried via cranial nerves. The parotid gland receives its parasympathetic input from the glossopharyngeal nerve (CN IX) via the otic ganglion, while the submandibular and sublingual glands receive their parasympathetic input from the facial nerve (CN VII) via the submandibular ganglion. These nerves release acetylcholine and substance P, which activate the IP3 and DAG pathways respectively.Direct sympathetic innervation of the salivary glands takes place via preganglionic nerves in the thoracic segments T1-T3 which synapse in the superior cervical ganglion with postganglionic neurons that release norepinephrine, which is then received by β-adrenergic receptors on the acinar and ductal cells of the salivary glands, leading to an increase in cyclic adenosine monophosphate (cAMP) levels and the corresponding increase of saliva secretion. Note that in this regard both parasympathetic and sympathetic stimuli result in an increase in salivary gland secretions.[3] The sympathetic nervous system also affects salivary gland secretions indirectly by innervating the blood vessels that supply the glands.
The postganglionic sympathetic fiber originates from PNS within a ganglion

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..).
No; some axons synapse in nearby autonomic ganglion. postganglionic fibers travel along either sympathetic nerves or rejoin at the spinal nerve.
the effects are ciliary muscle contraction leading to a constricted pupil and opening of the canal of schlemm to all aqueous humour drainage. Also there is an increase in tear formation. The PNS has a role in accomodation to light.
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
