Question:
When one neuron receives impulses to several neurons High energy in a muscle twitching is a sign of
a lot of mitochondria Repolarization Refractory period Depolarization threshold potential made by
oligodendrocytes that's how the CNS form myelin Myelin lipid material that forms a sheath like
covering around axons; insulates cells in nervous system neurons and neuroglia glial cells that form
, myelin sheath around the axons of peripheral neurons myelin helps with faster impulses 3 types of
joints How many cranial nerves?
Answer:
conversions membrane potential of a neuron returning to its resting negative state. Sodium exits and
potassium comes in period following stimulation during which a neuron or muscle fiber won't respond
to another threshold stimulus membrane of a neuron becoming less negative than the resting potential.
Sodium rushes in level of potential at which an action potential is triggered in a neuron or a muscle
fiber
