The nervous system and its bodily functions.

The aflutter trunk is the most(prenominal) complex part of the body, as they govern our thoughts, feelings, and bodily functions. It is an fundamental factor in apprehension because it faecal matter guide on to new discoveries for cures or diseases. The studies of the demented system helped lower expiration rates from heart disease, stroke, accidents, and so on The head-in-the-clouds system is a network of memorial pad of paper cells (nerve cells) that that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous system. Understanding how the neurons work is life-sustaining to understanding the nervous system. Neurons The neuron has two important structures called the dendrite and axon, overly called nerve fibers. The dendrites are mutual tentacles that sprout from the cell and the axon is peerless long appurtenance of the cell. The dendrites receive signals from separate neurons, duration the axon sends impulses to other neurons. Axons free fire extend to much than a meter long. second-rate coat neurons have hundreds of dendrites; therefore it burn down receive thousands of signals at the same time from other neurons. The neuron sends impulses by connection the axon to the dendrites of another(prenominal) nerve cell. The synapse is a prison-breaking between the axon and the nigh neuron, which is where entropy is transmitted from one neuron to another.

The neuron is negatively aerated and it bathes in fluids that lead positively charged jet and atomic number 11 ions. The membrane of the neuron holds negatively charged protein molecules. The neuron has pores called ion pay back to allow atomic number 11 ions to strait into the membrane, but prevent the protein molecules from escaping (potassium ions can freely pass with the membrane since the ion channels in general restrict atomic number 11 ions). When a neuron is wound up (not at rest), the pores open and the sodium ions rush in because of its attraction...
