sympathetic ganglion

Sympathetic ganglia are the tissue from which neuroblastoma tumours arise.

A Sympathectomy is a procedure during which at least one sympathetic ganglion is removed.

Sympathetic ganglia are the ganglia of the sympathetic nervous system.

Placement of an infusion catheter at a sympathetic ganglion extends the sympathetic blockade from hours to days or weeks.

Because it is innervated by preganglionic nerve fibers, the adrenal medulla can be considered as a specialized sympathetic ganglion.

This channel is expressed primarily in nociceptors of the dorsal root ganglion and the sympathetic ganglion neurons.

Sympathetic ganglia are located in two sympathetic chains close to the spinal cord: the prevertebral and pre-aortic chains.

SIF cells of sympathetic ganglia are separated into groups, each of which is surrounded by an SGC sheath.

Sympathetic ganglion cells are masses of neuronal cell bodies in the in the sympathetic branch of the visceral (autonomic) nervous system.

While L858H expressing sympathetic ganglion are depolarized 5mV relative to wild-type expressing neurons, their threshold for action potential initian is notably higher.

The vagal trunks then join with preaortic sympathetic ganglion around the aorta to disperse with the blood vessels and sympathetic nerves throughout the abdomen.

This occurs because Na1.8 channels, which are selectively expressed in addition to Na1.7 in DRG neurons, are not present within sympathetic ganglion neurons.

In sympathetic ganglia, dendritic growth begins prenatally and maximal expansion of the dendritic arbor occurs during postnatal weeks 1 and 2 [ 47 48 ] .

Prevertebral ganglia (or collateral ganglia, or preaortic ganglia) are sympathetic ganglia which lie between the sympathetic chain and the organ of supply.

Postganglionic sympathetic fibers from superior cervical sympathetic ganglion reach the gland as periarterial nerve plexuses around the external carotid artery and their function is mainly vasoconstriction.

Once they synapse in the sympathetic ganglion in the sympathetic trunk, they exit the trunk as gray rami to join the spinal nerve and innervate the appropriate structure.

Sympathetic preganglionic fibers tend to be shorter than parasympathetic preganglionic fibers because sympathetic ganglia are often closer to the spinal cord than are the parasympathetic ganglia.

The adrenal medulla is considered a sympathetic ganglion and like other sympathetic ganglia, is supplied by cholinergic preganglionic sympathetic fibers; acetylcholine is its neurotransmitter.

NGF is known have a predominant effect on the sympathetic ganglion cells and dorsal root ganglion cells with free nerve endings and the cholinergic neurons of the basal nucleus.

Chromaffin cells of the adrenal medulla are analogous to post-ganglionic neurons; the adrenal medulla develops in tandem with the sympathetic nervous system and acts as a modified sympathetic ganglion.

The SGCs of sympathetic ganglia follow the same basic structure as the SGCs of sensory ganglia, except that sympathetic ganglia also receive synapses.

The stellate ganglion (or cervicothoracic ganglion or inferior cervical ganglion) is a sympathetic ganglion formed by the fusion of the inferior cervical ganglion and the first thoracic ganglion.

Wherein the sympathetically maintained pain can be diagnosed by local anesthetic blockade of the appropriate sympathetic ganglion or adrenergic receptor blockade via intravenous administration of phentolamine, and rekindled by intradermal injection of norepinephrine.

In the sympathetic ganglia, satellite glial cells are one of three main types of cells, the other two being the sympathetic ganglion neurons and small intensely fluorescent (SIF) cells.

Ptosis may be caused by damage/trauma to the muscle which raises the eyelid, damage to the superior cervical sympathetic ganglion or damage to the nerve (3rd cranial nerve (oculomotor nerve)) which controls this muscle.
