Low-carb diets allow you to have somewhere around 50 to 150 grams of carbohydrates each day, MayoClinic.com reports. Since carbohydrates offer 4 calories per gram, this amounts to a minimal 200 to 600 calories from carbohydrates. Some plans make you go as low as 20 grams per day, or 80 calories from carbs, which is far less than the recommendation.
The nerve impulse causes the release of acetylcholine from the motor end plate. This causes the depolarization of the membrane of the adjacent muscle cell. Depolarization trig â¦ gers the release of calcium ions from the sarcoplasmic reticulum inside the muscle cell.t is the firing of a nerve which sends an electrical signal down  the axons of that nerve. The message propagates by the movement of  Sodium (Na) and Potassium (K) ions in â¦ and out of the axon  wall/sheath.
Most reflex arcs involve only three neurons. The stimulus, such as a needle stick, stimulates the pain receptors of the skin, which initiate an impulse in a sensory neuron. This travels to the spinal cord where it passes, by means of a synapse, to a connecting neuron called the relay neuron situated in the spinal cord.
