Functional Groups

2020
Functional groups are a group of atoms with characteristic properties, which when linked to the carbon skeleton of a molecule, alter the properties of that molecule. For example, the presence of certain functional groups on a molecule will make them hydrophilic, whereas others will make them hydrophobic. These functional groups are an indispensable part of organic chemistry and important components of biological molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Each...

An Optimized Procedure for Fluorescence-activated Cell Sorting (FACS) Isolation of Autonomic Neural Progenitors from Visceral Organs of Fetal Mice

Cited by 6 •
2012
An optimized procedure to purify neural crest-derived neuronal progenitors from fetal mouse tissues is described. This method takes advantage of expression from fluorescent reporter alleles to isolate discrete populations by fluorescence-activated cell sorting (FACS). The technique can be applied to isolate neuronal subpopulations throughout development or from adult tissues.
FAQs
Sympathetic and parasympathetic pathways adjust organ activity according to internal and external conditions. In visceral function, these pathways help coordinate changes across organs such as the heart, lungs, gastrointestinal tract, bladder, and reproductive organs. Their activity forms part of autonomic regulation, allowing organ processes to remain integrated with broader homeostatic demands without requiring conscious direction.
Sensory feedback informs the nervous system about conditions within the body, allowing neural circuits to modify organ activity. Reflexes use this incoming information to support rapid adjustments in visceral processes. Studying these feedback pathways helps explain how the brain and body communicate and why disrupted signaling can affect regulation of internal organs.
The enteric nervous system provides neural coordination within the gastrointestinal tract, while endocrine signals add chemical communication to visceral control. Together with autonomic pathways and sensory feedback, they connect local organ activity with wider regulatory processes. This interaction is especially relevant when examining digestion and the broader coordination of internal organ function.
Neural circuits and reflexes explain how visceral responses are organized and adjusted outside conscious control. They link sensory information from internal organs with changes in autonomic output, helping researchers analyze communication between the brain and body. This perspective is important for understanding normal regulation as well as disturbances involving organ control, pain, or stress responses.
Research can examine how autonomic pathways, sensory feedback, and organ responses become disrupted in autonomic disorders. Comparing these elements helps clarify whether problems involve neural communication, reflex regulation, or coordination among internal organs. Such work provides scientific context for conditions in which cardiovascular regulation, digestion, bladder activity, or other visceral processes are affected.
Visceral function connects neuroscience with the study of stress responses and pain because internal organs communicate with the nervous system through sensory pathways, reflexes, and autonomic regulation. Investigating these relationships can show how brain-body signaling influences organ activity. The same framework also supports research into cardiovascular regulation, digestion, and other internal processes.
