Top 10 Commonly Confused Words in Neuropathology

Top 10 Commonly Confused Words in Neuropathology 1. Axon vs. Dendrite The first pair of words that often cause confusion are 'axon' and 'dendrite.' While both are integral parts of a neuron, they have distinct functions. Axons transmit signals away from the cell body, while dendrites receive signals from other neurons. Remember, axons are like highways, carrying information, while dendrites are like branches, receiving it. 2. Ischemia vs. Infarction Next, we have 'ischemia' and 'infarction.' Ischemia refers to reduced blood flow to a tissue, leading to oxygen deprivation. On the other hand, infarction occurs when the blood supply is completely cut off, resulting in tissue death. Think of ischemia as a warning sign, while infarction is the severe consequence. 3. Glioma vs. Meningioma Moving on, 'glioma' and 'meningioma' are often used interchangeably, but they are different types of brain tumors. Gliomas originate from glial cells, which support and protect neurons. Meningiomas, however, arise from the meninges, the protective layers surrounding the brain. So, the key distinction lies in their point of origin. 4. Atrophy vs. Hypoplasia When it comes to 'atrophy' and 'hypoplasia,' both involve underdevelopment, but they differ in timing. Atrophy occurs when a tissue or organ shrinks due to injury or disuse.
