Flash Animations

Physiology and Anatomy

Listed below are a collection of physiology animations and anatomy animations. These animations are intended to support text or lecture and it is important that they are not seen as stand-alone reference material.


Notes:
If you or your students discover any factual errors in the animations please let me know: andrew@visualization.org.uk
Some of the animations can only be accessed from the university network - please contact Liz Hodgson in the LDU if you would like them on WebCT so that students can access them externally.
Visual detail in Flash animations can often be magnified (click on the animation with the right mouse button and use the zoom control)

Here are some animations of organs/organ systems:

Cranial nerves (No text version)

Cranial nerves (Customised version))

Anatomical directions and sections.

Vertebrae: meninges etc.

Brain: meninges cerebrospinal fluid etc.

Skin turgor

Contraction and electrical activity in the heart (Slowed down representation)

Intestinal villi (diagram)

Gastrointestinal tract (diagram)

Stomach, liver etc. (diagram)

Salivary glands (diagram)

Hip and dislocation (diagram)

Eye (diagram)

Nutrition animation

This GIT animation represents the anatomy and physiology of the gut including: intestines, the lumen of jejunum and details including: digestion and absorption of nutrients, enzyme action on starch by salivary and pancreatic amylase to produce disaccharides such as lactose and sucrose. It includes structures such as: muscularis externa, lymphatic vessel, villi, epithelial cells, microvilli, bi-lipid membrane. Also examined are: diffusion of lipids across a bi-layer membrane, co-transport, facilitated diffusion, primary active transport, the sodium/potassium pump which develops a concentration gradient of ions, and finally the breakdown of glycogen to glucose in muscle cells.

Biliary_tract animation

This animation represents a section through the Duodenum, biliary tree including Hepatic Duct, Cystic Duct, Common Bile Duct, Gallbladder and Sphincter of Oddi. Gallstones are represented and the context of effects such as biliary colic, cholecystitis, cholangitis,jaundice and pancreatitis considered.

Epilepsy animation

This animation simulates the A and P of epilepsy. It shows seizure in different parts of the cortex of the brain and corresponding effects. Also shown are possible targets for some anticonvulsant drugs: the membrane based receptors of a neuron, its axon and voltage-gated sodium channels, its synapse with GABA effects on chloride ion movement, calcium flux, neurotransmitter re-uptake, and enzyme activity.

Heart animation

This representation looks at pre and post-natal circulation in a normal and abnormal heart. conditions such as Patent Ductus Arteriosus (PDA), Atrial Septal Defect (ASD) and Ventricular Septal Defect (VSD) are simulated.

Schizophrenia animation

This animation examines Schizophrenia and neural pathways associated with the condition and treatment. (Nigrostriatal, Mesolimbic, Mesocortical and Tuberoinfundibular dopamine pathways along with serotonin pathways). We consider the relationship between tardive dyskinesia and some neuroleptic drugs along with disorders (akathisia and dystonia) normally associated with Parkinson's disease. The animation also looks at activities at the synapse and possible mechanism of action for antipsychotic and other drugs.

Pain animation

(Uclan network only)

This animation represents the anatomy and physiology of pain. It shows structures and processes involved in the perception of pain. The animation can be modified using the Pain Builder animation below but please seek advice first.

Pain animation customisation tool
This tool allows you to create text files which customise the links and quiz. (please seek advice on how to use this: andrew@visualization.org.uk)

Stroke animation basic version

(Uclan network only. Please let me know first if you want to use this.)

This animation shows two examples of interrupted blood flow in arteries of the brain along with some of the factors affecting the outcome of a stroke.
