Introduction Neurons (also known as neurons‚ nerve cells and nerve fibers) are electrically excitable and the most important cells in the nervous system that functions to process and transmit information. Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body. It is primarily the surfaces of the dendrites that receive chemical messages from other neurons. One extension is different from all the others‚ and is called

Life Lessons A moment that will forever change my life happened two years ago during my sophomore year‚ I will never forget it‚ but I am also thankful that it happened because I have learned from my mistake and it has taught me a few valuable life lessons. Two years ago‚ I moved up to Eugene to live with my aunt and uncle for the year to experience a new life setting. I was thrilled to experience new things‚ meet new people‚ and learn new ways of living in a big city. It was the first day of

Question 3 Using any peripheral nerve bundle as a model‚ describe using figures (a) the general anatomical structure with key constituents identified and (b) the heterogeneity in the electrical conductivities of the different constituents. For this question‚ I will be using the sciatic nerve as my model. The sciatic nerve consists of several main structures as can be seen in Figures 5 below. Figure 5: Cross section of the sciatic nerve. The inset in the top image shows individual fibers wrapped

Session 9: The Nervous System - Assignment #2 PhysioEx Assignment : Exercise 3 Neurophysiology of Nerve Impulses Activity 1: The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Increasing the extracellular K+ causes the membrane potential to change to a less negative value because when K+ ions diffuse out across the membrane they are leaving behind a net negative charge. 2. Explain

Optic nerve sheath diameter (ONSD) The anatomy of the optic nerve sheath : The intraorbital section of the optic nerve extends from the globe‚ where it inserts medially‚ to the optic canal located in the lesser wing of the sphenoid bone. It is encased by a meningeal sheath consisting of dura mater‚ arachnoid mater and pia mater. Cerebrospinal fluid is contained in the trabeculated subarachnoid space and is continuously and slowly filtered. As a result the optic nerve sheath is in direct
