Nancy the neuron has just fired an action potential. Now she cannot fire another action potential until she resets her electrical potential. She is in a refractory period. The refractory period starts after the hyper-polarization of the neuron. In this phase the neurons is inhibited of generating further action potentials, and the recovery to resting potential of the neuron membrane begins with the potassium ions slowly leaking into the cell.
Automatic Nervous system
In human, the automatic nervous system is part of the peripheral
nervous system and it consists of the sympathetic division and the parasympathetic
division. Automatic nervous system is regulated by hypothalamus which
controls our internal organs and glands such as blood pressure, breathing, pulses
and arousal in response to emotional circumstances.
Answer:
Turkey allegedly causes drowsiness because it is packed with a nutrient called tryptophan. Tryptophan is one of 20 naturally occurring amino acids—the building blocks of proteins. Because the body is unable to manufacture tryptophan on its own, it must be obtained from food protein.
Answer:
ATP levels would fall at first, decreasing the inhibition of PFK and increasing the rate of ATP production.
Answer:
In addition some cells divide continuously throughout life to replace cells that have a high rate of turnover in adult animals Cell proliferation is thus carefully balanced with cell death to maintain a constant number of cells in adult tissues and organs
Explanation:
