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 poster offers a basic level of understanding of ABGs for medical students. I have also made an ID-card-sized version which can be easily used on the ward. Students can work around the table, looking at pH, then CO2 and then HCO3- and find the answer in the correct box.
This booklet was developed as a part of Special Study Unit (Doctors as Teachers) at Peninsula Medical School. This booklet covers some of the important aspects of Ophthalmology.
This booklet could be used as a quick revision guide before finals and also could be used along Ophthalmology placements. The purpose of this booklet is to provide some insight into the most common presentations of red eye and their management.
This poster shows one of a series of drawings which were created using Adobe Illustrator CS4 and Adobe Photoshop CS4. A series of Coronal and Axial CT sections from a 27 year old male, who consented to their use for education (including specific consent for the purposes of this competition), was used as a template for the drawings which are then displayed alongside the original grey-scale image.
The aim of the drawings is to help with interpretation of CT imaging by placing them alongside a coloured illustration of the original. Sectional images are a very valuable tool for learning the 3D relationships of anatomy.
An OSCE presentation by Sarah Lawrence and Oscar Swift of UCLU MedSoc aimed at clinical medical students. It will briefly go through how to perform a fundoscopy station in 5 minutes and the features of the basic pathologies (including diabetic retinopathy, hypertensive retinopathy, retinal artery/vein occlusion and others) you might see.
