They form an essential part of the innate immune system, with their functions varying in different animals. What are Read more…

What is thoracic electrical bioimpedance?

What is thoracic electrical bioimpedance? Thoracic electrical bioimpedance (TEB) devices, a form of plethysmography, monitor cardiac output by non-invasively measuring hemodynamic parameters, including: thoracic fluid status, stroke volume, and systemic vascular resistance. How is ICU cardiac output measured? Aortic flow velocity time integral (VTI) multiplied by the cross-sectional area (CSA) Read more…

What are the basic steps involved in the transmission of an action potential across a neuromuscular junction?

What are the basic steps involved in the transmission of an action potential across a neuromuscular junction? Neuromuscular transmission may be divided into three processes: (1) presynaptic terminal depolarization and ACH release; (2) ACH binding and ion channel opening; and (3) postsynaptic membrane depolarization and muscle action potential generation. … Read more…
