Development of the rat superior cervical ganglion: ganglion cell maturation.
The development of superior cervical ganglion cells has been studied in the fetal rat. Sympathetic cells appear first in thoracic sites and, one day later, in cervical sites; localized proliferation among these cells gives rise to the superior cervical and stellate ganglia. The maturation of superior cervical ganglion cells was examined by staining these neurons with horseradish peroxidase in f...
متن کاملStereological Study on the Neurons of Superior Cervical Sympathetic Ganglion in Diabetic Rats
Background: Most research on autonomic dysfunction of diabetes mellitus is conducted on ganglions innervating gastrointestinal (GI) tract and there are limited works focusing on cervical sympathetic ganglia. The effects of diabetes mellitus (DM) on the neurons of superior cervical sympathetic ganglion (SCSG) are investigated by stereological methods. Material and Methods: Female rats (n=72) ran...
متن کاملNeurotransmitters and Their Receptors in the Rat Superior Cervical Ganglion
The superior cervical ganglion (SCG), the sympathetic organ innervating the carotid body (CB), lies at the bifurcation of the common carotid artery, near the CB. The ganglion is composed of functional subsets of neurons showing different sympathetic phenotypes. The expression of putative neurotransmitters and their receptors in the rat SCG was investigated at light microscopical level using imm...
متن کاملDevelopment of the rat superior cervical ganglion: ingrowth of preganglionic axons.
The growth of sympathetic preganglionic axons has been studied in the fetal rat. Preganglionic axons first emerge from the spinal cord and enter the paravertebral chain of ganglia between days 12 and 13 of gestation (E12 to E13). By E14, hundreds of preganglionic neurons have sent axons into the sympathetic chain. Even at this age, the arrangement of the preganglionic axons conforms to the adul...
متن کاملDevelopment of the rat superior cervical ganglion: initial stages of synapse formation.
Synapse formation in the rat superior cervical ganglion has been investigated electrophysiologically and at the ultrastructural level. Preganglionic axons first enter the superior cervical ganglion between days 12 and 13 of gestation (E12 to E13), and on E13 a postganglionic response can be evoked by preganglionic stimulation. The susceptibility of this response to fatigue and to blocking agent...
