Work on your nervous system worksheets this week. This is an ongoing assignment, so different sections will be due on different days. The first two sections, 35-2 and 35-3, will be due on Wednesday.
EXTRA LEARNING:
Today, we learned about the basic structures of neurons, including some diseases and disorders that result from neuron deterioration. One example was Tay-Sachs Disease, which results when harmful cell membrane components (known as gangliosides) accumulate in cerebral nerve cells and eventually lead to their death. Another genetic neuro-degenerative disease that was the featured in the film Lorenzo's Oil is adrenoleukodystrophy (ALD). (Those who are interested in watching Lorenzo's Oil may find it on YouTube.) In ALD, over-accumulation of a certain fatty acid leads to damage of myelin. Without the myelin sheath, neurons cannot conduct impulses normally, leading to damage of the brain and peripheral nervous system.
