The phrase "afferent sympathetic" is correct and usable in written English.
It can be used in contexts related to anatomy or physiology, specifically when discussing the sympathetic nervous system and its pathways.
Example: "The afferent sympathetic fibers play a crucial role in transmitting sensory information from the periphery to the central nervous system."
Alternatives: "sensory sympathetic" or "incoming sympathetic".
Propofol inhibits afferent sympathetic action and cardiac baroreceptor reflexes [7, 8].
In the present study we show that the lack of change in renal sympathetic activity may be caused by an inability of RDN to cause a sufficient decrease in afferent sympathetic nerve activity as 123I mIBG-uptake did not change significantly.
Thus, EPR in the absence of work load appears to be driven by stimulation of the muscle stretch receptors that creates an afferent sympathetic stimulus [ 14].
Although the proposed mechanisms above highlight the hyporesponsiveness of the efferent or afferent sympathetic receptors in causing refractory hypotension, it remains uncertain if stimulation of the skeletal chemosensitive or mechano-receptors through dynamic exercise could modulate haemodynamics in these patients.
Catheter-based radiofrequency ablation of the efferent and afferent sympathetic nerves which lie within and just beyond the adventitia of the renal arteries has been shown to be a highly effective treatment for resistant hypertension (Fig. 1).
In this manuscript, we review the data that suggests that selective impairment of renal somatic afferent and sympathetic efferent nerves in patients with resistant hypertension both reduces markers of central sympathetic drive and favorably impacts diseases linked through central sympathetics—insulin resistance, heart failure, congestion, diuretic resistance, and cardiorenal disorders.
Abnormal coupling between primary sensory afferent and sympathetic efferent neurons has been documented in animal models of neuropathic and inflammatory pain.
Physiologically, RH has been associated with elevated activity in both the efferent and afferent renal sympathetic nerves.
Removal of both the renal somatic afferent and sympathetic efferent conduction may address both the total body excess volume and the maldistribution of stored blood.
Synovial tissue is richly innervated with neuropeptide-containing primary afferent and sympathetic neurons [ 5- 7] and there is evidence that the release of these neuropeptides powerfully influences the severity of chronic inflammatory diseases, including RA [ 8, 9].
The difference between afferents and efferents (for a single twin pulse) may reflect a difference in the potassium/sodium channels that are expressed in afferents and sympathetic efferents.
