When a nerve impulse (action potential) arrives at a synapse, calcium ions are absorbed into the neuron. they stimulate the synaptic vesicles, containing neurotransmitter, to fuse with the cell membrane and release the neurotransmitter into the synapse.
No, the skeletal system stores calcium.

calcium metabolism
Acetylcholine is the neurotransmitter released by the nervous system that excites muscle cells, leading to muscle contraction.
calcium or oxygen or blood tada
Your nervous system needs calcium to function. If you don't have it in your diet then your body will extract calcium from your bones to supply it. This leads to things like "brittle bone disease". In other words, it will weaken your skeletal structure to keep you alive. Breaking a bone is secondary, to your body, to keeping your nervous system alive.
When the nervous system signals a muscle to contract, calcium channels open in the muscle cell membrane. Calcium ions then flow into the muscle cell, triggering a series of biochemical events that eventually lead to muscle contraction.
The nervous system The central nervous system
No. Nervous System is comprised of the Central Nervous System (CNS) and the Peripheral Nervous System (PNS) The PNS is comprised of the Somatic Nervous System and the Autonomic Nervous System The Autonomic Nervous System is comprised of the Sympathetic Nervous System, the Parasympathetic Nervous System and the Enteric Nervous System
The Sympathetic Nervous System and the Parasympathetic Nervous System
The main ions involved with the nervous system are potassium, sodium, chloride, and calcium. Each have different effects such as changing the voltage of the membrane and changing the confirmation of membrane bound proteins.
The peripheral nervous system is the portion of the nervous system away from the central nervous system. It consists of nerves that connect the central nervous system to the rest of the body, including sensory and motor neurons. The peripheral nervous system is responsible for transmitting information to and from the central nervous system.
