An edited version of my Friday Evening Discouse given to the Royal Institution on 11 April 2008.
Abstract: The vagus nerves (cranial nerve X) connects our brainstem to the body, facilitating monitoring and control of many automatic functions; the vagus electrically links our gut, lungs and heart to the base of the brain in an evolutionarily-ancient circuit, similar between mammals and also seen in birds, reptiles, and amphibians. The vagus comprises a major part of the parasympathetic autonomic nervous system, contributing to the motor control of important physiological functions such as heart rate and gut motility. The vagus is also sensory, relaying protective visceral information leading to reflexes like cough and indication of lung volume. The vagus has been described as a neural component of the immune reflex. By monitoring changes in the level of control exerted by the vagus, apparent as beat by beat changes of heart rate, it is possible to indirectly view the effect of pharmaceuticals and disease on brainstem function and neural processes underlying consciousness. The paired vagus nerves of humans have different functions, and stimulation of the left vagus has been shown to be a therapeutic treatment for epilepsy, and may modulate the perception of pain.
An anatomy revision guide, focused upon the upper limb, lower limb & back.
Originally created in 2009 as a study aid for students at Cardiff University School of Medicine, it was substantially updated in 2010, and this Second Edition contains more detailed chapters, particularly with respect to musculature, cross-sections & relevant clinical anatomy.
Further information can be found under the Preface & Introduction.
This is a link to quizzes made using Wikiversity. During a Student selected component my colleague and I experimented with wikiversity. Although the quizzes made were basic, the concept is that they can be edited and added to by anyone using them to improve them and make them more interactive. The best example are probably the shoulder muscles and lateral aspect of the hand quizzes.
A slideshow containing all of the musculoskeletal radiology required to pass most finals radiology OSCE stations, with many examples. Explanations of each radiograph are included after the film has been displayed, giving you the chance to attempt a description first.
The liver is one of the most confusing organs to get to grips with, and one that medical students know very little about prior to startinf medical school. This document aims to explain everything a first year medical student needs to know about the liver in a clear and concise manner, with the aid of bulletpoints and diagrams.
This chest examination video is part of the MedPrep tutorial video series: http://www.medprep.in/clinical-examination-videos.php which has received 20,000+ views on Youtube.
The videos are designed to be concise and engaging, at times with humour. I hope you enjoy viewing them and find them useful.
