A vascular plexus is visible at the limit between the neurocranium and the overlying dermal bones.
Sonographic imaging permits differentiation of those two intracranial conditions by visualization of the subarachnoid space and the choroid plexus.
Compression injuries occur when pressure is applied to the plexus for a period of time.
Such 'gap' lesions are common, for example, after complex lesions of the brachial plexus where proximal and distal stumps retract.
A week after the last dose of antigen, jirds were bled from the retro-orbital plexus and immune sera were isolated.
Blood samples from the retro-orbital vein plexus of mice were taken at intervals as indicated.
These agents may exert their effect on local opioid receptors within the myenteric plexus of the gastrointestinal tract.
This overrides any myenteric plexus stimulation so that the sphincter relaxes.
