Galvani\'s experimet tells us that nerves carry messages to the muscle through electrical impulses.
Ions, such as sodium and potassium, are responsible for creating electrical charges in muscle cells. When a nerve signal triggers the release of these ions, it causes a change in the cell's electrical charge, which leads to muscle contraction. This process is essential for communication between nerves and muscles for movement.
muscle nerves carry messages from the brain to tell the muscle to contract.
Nerves relay messages by transmitting an electrical impulse.
Electrical messages in the body are called action potentials. These are rapid changes in the electrical voltage across a nerve cell membrane that allow for the transmission of signals between cells.
Electrical tests of muscle and a muscle biopsy show characteristic changes.
electrical impulses
The ability of a muscle to transmit electrical current is termed conductivity. This refers to how well the muscle tissue can carry an electrical impulse, allowing for proper communication between nerves and muscle fibers to produce movement.
Nerve!
Synapses let the "message" travel to muscle cells.
