How do we know neuran are surrounded by sodium and potassium ions?
Answers
◆Néuron
⚩Neuron or the nerve cell forms the basic components of the nervous system.
⚩A typical neuron possesses a cell body called soma, hair like structures called as dendrites and an axon.
⚩They are cells within the nervous system that transmits information to other nerve cells, muscles or glands.
◆ Ion transportation in neuron
⚩The neuron channels can be opened or closed according to the needs of the cell.
Transmembers protein called transporters,use the energy of ATP to force ions or small molecules through the membrane against the concentration gradient.
Q.How do we know neuron are surrounded by sodium and potassium ions?
Ans.The inside of a neuron has negative charge, relative to the cell existor,from the movement of K+ out of the cell. Deporalization opens both sodium and potassium channels in the membrane, allowing the ions to flow into and out of the axon respectively.
