16‚ 2014 A Case of Spinal Cord Injury 1. Describe the functional anatomy of the spinal cord using the following terms: white matter‚ gray matter‚ tracts‚ roots and spinal nerves. The spinal cord consists of a superficial White matter and a deep Gray matter. The white matter consists of myelinated axons‚ which form nerve tracts and the Gray matter consists of neuron cell bodies‚ dendrites and axons. The white matter in each half of the spinal cord is organized into ventral‚ dorsal and lateral

malfunctions of the nerves. Disorders can range from Palsy and Parkinson’s in which symptoms are movements such as tremors to Alzheimer’s which is mental deterioration and loss of memory. Disorders stemming from the nervous system can be severe. A few disorders that deal with movement and muscles are Amyotrophic lateral sclerosis (also known as Lou Gehrig’s disease)‚ Myasthenia gravis‚ and as said before Parkinson’s. Amyotrophic lateral sclerosis is a disease of the nerve cells in the brain and

Action Potentials in the Ventral Nerve Cord of the Periplaneta Americana Andrew Goldsmith (andrew.goldsmith@uconn.edu)‚ Tuesdays 1-4PM Section: 2 (Partner: Ana Charalambides) Abstract In polikiotherms it is known that the amount of locomotion varies based on the environmental temperature. We believe that this is caused by differences in the neural activity. We therefore investigated how temperature changes affect the extracellular neural activity in the ventral nerve cord of the Periplaneta Americana

Why is an EMG test done? An EMG is often performed when patients have unexplained muscle weakness. The EMG helps to distinguish between muscle conditions in which the problem begins in the muscle and muscle weakness due to nerve disorders. The EMG can also be used to detect true weakness

on to the olfactory nerve. This nerve enters the brain and will cause the subject to understand the odor to be hamburger‚ of which he wants to eat. The brain then makes the decision to move forward with eating the hamburger. The brain must tell the hand to reach out and grab the burger to bring it to the mouth. It does so by sending an impulse down the spinal nerve until it branches off on to the arm nerves‚ which include the radial‚ ulnar‚ and median nerve. These three nerves in conjunction will

It is made up of the Central Nervous System (or CNS) and a network of nerves that extend from the CNS to all parts of the body. The nervous system regulates both voluntary activities‚ such as walking and talking‚ and involuntary activities‚ such as breathing‚ which you make no conscious decisions about. The CNS has two main
