This animation allows you to visualize the structure of a peripheral nerve, and to compare a simplified diagram to an actual photo of that structure.

<![CDATA[Neuromuscular synapse #2]]>

This animation presents the structure and the ultrastructure (also called the “fine structure”) of the neuromuscular junction. Microphotographs enable one to relate the schematic diagrams to the real structures.

<![CDATA[Structure and ultrastructure of the neuron]]>

This animation presents the structure and ultrastructure (or fine structure) of the motor neuron

<![CDATA[Spinal cord]]>

From spinal cord to nerve cell bodies.

<![CDATA[Neuromuscular junction]]>

The majority of synapses are junctions between neurons. A motor end plate lies at the synaptic extremity of a neuromuscular junction. The axon of the motor neuron is connected to a muscle fiber, where it controls the excitation of that fiber.

<![CDATA[Brain Quiz]]>

Test your knowledge of anatomy by labeling the diagram presented here in the shortest amount of time and with the fewest errors. Then score your performance. The scoring system takes into account both the time needed to complete the quiz, and the number of tries you need to do so.

<![CDATA[Mechanisms of drug action ]]>

This animation presents the different mechanisms of action of drugs that are at the origin of drug dependence.

<![CDATA[Cranial CT scan]]>

The  technique of Tomodensitometry  (TDM) is often referred to as a “scanner” because of confusion between the process itself and  the apparatus employed in that process. This imaging technique depends of the use of x-rays. It is particularly useful for observing the brain.
The x-ray beam is emitted by an x-ray tube and is then transformed by a detector into an electrical message that is sent to a computer.
The system emitter/detector is moved around the patient and computer analysis of received signals, from different angles, enables the creation of images in section.

This animation presents the two modes of conduction of nerve messages :

  • Continuous conduction
  • Sal tatory conduction
