Solutions

Expert Solution

The nerve impulse occurs as a result of the difference in the electric charge across the neuron's plumbing membrane.

When a neuron is not actively transmitting nerve impulses, it is in a state of relaxation, ready to transmit nerve impulses. During relaxation, the sodium-potassium pump maintains the controlling voltage across the entire neuron cell membrane.
The sodium-potassium pump is an active transport system that removes sodium ions from the cells and potassium ions to the cells. The sodium-potassium pump transports both ions from low to high concentrations, using the ATP energy and the carrier proteins in the cell membrane.
Sodium is the primary ion in the cell's outer membrane, and potassium is the primary ion in the cell membrane. This difference in concentration creates an electrical gradient across the cell's hole, called the relaxation energy. Controlling the energy of the membrane with proper control is essential for the transmission of nerve conduction.

The sodium-potassium pump which uses the active transport method to move molecules from high to low concentrations. Sodium-potassium pump removes sodium ions from the flow and potassium ion from the cell. This pump is powered by ATP. For each broken ATP, 3 sodium ions break out and the potassium ions enter.

Calcium, a well-charged molecule, is useful in many places in the human body. The role of calcium within the nervous system ranges from the activation of the sensory signal to the action that occurs. Calcium is a mark on the heart of the cell's muscles and continues to be useful until the contracis complete.
