In this lecture ´´Gastrointestinal Physiology: General Principles´´ are explained. Section one is about ´´Gastrointestinal Motility´´. Section two is about ‘’Neural Control of Function’’. Section three is about ‘’Autonomic Control’’. Section four is about ‘’Hormonal Control and Functional Motility’’. Section five is about ‘’Gastrointestinal Blood Flow’’.
In the very first slide introduction is given. In the next slide physiological anatomy is presented. After that electrical activity is discussed. This is followed by the elucidation of slow waves of electrical activity. Then information on spike potential is delivered.
Neural Control of Function
Educator started this section by the explanation of enteric nervous system. This is followed by the elucidation of myenteric and submucosal plexuses. In the last slide secretion of neurotransmitters is focused.
At first parasympathetic stimulation is illustrated. After that sympathetic stimulation is discussed. Then elucidation of gastrointestinal reflexes is given.
Hormonal Control and Functional Motility
Educator’s prime focus is gastrointestinal hormones. In the next slide propulsive movements – peristalsis is explained. In the last slide mixing movements are presented.
Gastrointestinal Blood Flow
This section is started by the discussion of Blood Supply – Anatomy. Then educator talks about increased blood flow during activity. Finally, nervous control of blood flow is highlighted.
