The Lymphatic System

V F Murphy Friday 10th April 2009

The capillaries are very permeable, and feature a loose overlap feature, where with the aid of small anchoring filaments the vessel can take large particles and stay open where the external pressure is greater. This causes problems however, as the vessel also carries large particles, such as viruses, pathogens, and ce…

From cutting-edge research in cognitive patterns of amputees to help quicken the rehabilitation process to helping patients deal with residual issues such as the constant realization that they’ve permanently lost a part of themselves, prosthetics is as much a science as…

Atherosclerosis Diagnosis

V F Murphy Sunday 20th June 2004

Atherosclerosis is a disease characterised by the build up of scleroid lesions, termed atheroma. These atheroma take the form of porridgelike blockages within the human circulatory system.

These blockages act to distrupt the normal course of circulation, leading to infarction, whereby blood is unable to reach a certain area, or the formation of thrombosis, where the blood effectively clots within arteries or veins. These can lead to heart attacks, or strokes.

Muscle Contraction and Hills Model

V F Murphy Monday 10th May 2004

Structure of Muscle

Muscle is made up of fibrous components termed myofibrils. Each of these is formed by a large number of sarcomeres. Each sarcomere feature repeated bands of Actin and Myosin, causing a banded apperance during microscopy.

The Sliding Filament Model

Huxley proposed that not only did muscles contract by changing the degree of overlap between the actin and myosin filaments, but the force was determined by the degree of such overlap.

Testing the Sliding Fila…
