The key difference between neuroblastoma and medulloblastoma is that neuroblastoma is a cancer of immature nerve cells that starts outside of the brain, usually in the nerve tissue near the upper spine, chest, abdomen, or pelvis, while medulloblastoma is a brain cancer that starts in the lower back part of the brain called the cerebellum. The […]
Difference Between Depolarization and Hyperpolarization
The key difference between depolarization and hyperpolarization is that in depolarization, sodium channels open up, letting Na+ ions flow inside the cell, making membrane potential less negative, while in hyperpolarization, excess potassium channels open up, letting K+ ions to flow out the cell, making membrane potential more negative than the resting potential. Action potential is […]
Difference Between Action Potential and Synaptic Potential
The key difference between action potential and synaptic potential is that action potential is the electrical potential difference across the plasma membrane of excitable cells such as neurons, muscle cells and endocrine cells, etc. while synaptic potential is the post-synaptic potential change in neurons. The nervous system transmits signals among the different parts of the […]
Difference Between Amacrine and Horizontal Cells
The key difference between amacrine and horizontal cells is that amacrine cells receive information from the bipolar cells while horizontal cells receive information from photoreceptors. Photoreceptors, bipolar cells, ganglion cells, horizontal cells and amacrine cells are the five types of neurons found in our retina. All these neurons contribute to the processing of visual information in […]
Difference Between Bipolar Cells and Ganglion Cells
The key difference between bipolar cells and ganglion cells is that bipolar cells are interneurons present in the second layer of the retina which transform visual information from photoreceptors to ganglion cells while ganglion cells are retinal ganglion neurons in the third layer of the retina that carry the nerve impulses from bipolar cells to […]
Difference Between Anterograde and Retrograde Transport
The key difference between anterograde and retrograde transport is that anterograde transport moves physiological materials towards presynaptic terminals while retrograde transport moves physiological materials back to the cell body from the periphery. Axonal transport is a physiological process that transports proteins and other substances synthesized in the neurosome to the nerve endings through the cytoskeleton. […]
Difference Between Microglia and Macroglia
The key difference between microglia and macroglia is that microglia are the immune cells of the central nervous system that protect it against injuries and diseases while microglia are neuronal supportive cells which mainly provide nutrient support, maintain brain metabolism and homeostasis, and produce myelin sheath around axons. Glial cells or neuroglia are the most […]
Difference Between Astrocytes and Oligodendrocytes
The key difference between astrocytes and oligodendrocytes is that astrocytes are the most common type of glial cells in the central nervous system and they form the blood brain barrier and regulate chemicals around the neurons while oligodendrocytes are the glial cells that synthesize the myelin sheath around the axons of the central nervous system […]
Difference Between Depolarizing and Nondepolarizing Neuromuscular Blockers
The key difference between depolarizing and nondepolarizing neuromuscular blockers is that depolarizing neuromuscular blockers act as acetylcholine receptor agonists while nondepolarizing neuromuscular blockers act as competitive antagonists. Neuromuscular blockers are commonly used for skeletal muscle relaxation. They are also called skeletal muscle relaxants. They block neuromuscular transmission at the neuromuscular junction (junction between neuron and […]
Difference Between Neurogenesis Neuroplasticity and Neuroregeneration
The key difference between neurogenesis neuroplasticity and neuroregeneration is that neurogenesis refers to the formation of new neurons in the brain while neuroplasticity refers to the brain’s ability to reorganize itself by forming new neural connections throughout life and neuroregeneration refers to the regrowth or repair of nervous tissue, cells or cell products. Injuries in […]
