axoplasm การใช้

• Axoplasm contains both the mRNA and ribonuclearprotein required for axonal protein synthesis.
• In axoplasmic transport, materials are carried through the axoplasm to or from the soma.
• Axoplasm is integral to the overall function of neurons in propagating action potential through the axon.
• Furthermore, axoplasm contains the pre-synaptic vesicles of neurotransmitter which are eventually released into the synaptic cleft.
• The amount of axoplasm in the axon is important to the cable like properties of the axon in cable theory.
• Similarly, in an axon, some of the current traveling longitudinally through the axoplasm will escape through the membrane.
• These axons were mainly studied to understand action potential, and axoplasm was soon understood to be important in membrane potential.
• Intake of acetylcholine in axoplasm is prevented and the presynaptic nerve releases more acetylcholine into the synapse that initially causes bradycardia.
• Axoplasm has a different composition of organelles and other materials than that found in the neuron's soma ) or dendrites.
• This understanding of the relationship of axoplasm regarding transport and electrical potential is critical in the understanding of the overall brain functions.
• Axoplasm was not a main focus for neurological research until many years of learning of the functions and properties of squid giant axons.
• The composing cytoskeletal elements of axoplasm, neural filaments, and microtubules provide the framework for axonal transport which allows for neurotransmitters to reach the synapse.
• The fast axonal transport system uses the axoplasm for movement, and contains many non-conductive molecules that change the rate of these electrical potentials across the axon.
• It actually proves quite difficult to isolate axons from the myelin that surrounds it, so the squid giant axon is the focus for many studies that touch on axoplasm.
• Neuroscientists are often interested in knowing how fast the membrane potential, V _ m, of an axon changes in response to changes in the current injected into the axoplasm.
• The axoplasm was at first just thought to be very similar to cytoplasm, but axoplasm plays an important role in transference of nutrients and electrical potential that is generated by neurons.
• The axoplasm was at first just thought to be very similar to cytoplasm, but axoplasm plays an important role in transference of nutrients and electrical potential that is generated by neurons.
• The electrical resistance of the axoplasm, called axoplasmic resistance, is one aspect of a neuron's cable properties, because it affects the rate of travel of an action potential down an axon.
• Where " a " is the radius of the axon, " R " is the specific resistance of the axoplasm, and " x " is the position along the nerve fiber.
• If the axoplasm contains many molecules that are not electrically conductive, it will slow the travel of the potential because it will cause more ions to flow across the axolemma ( the axon's membrane ) than through the axoplasm.
