excitation /ex·ci·ta·tion/ (
ek″si-ta´shun)
2. the addition of energy, such as excitation of a molecule by absorption of photons.
direct excitation electrostimulation of a muscle by placing the electrode on the muscle itself.
indirect excitation electrostimulation of a muscle by placing the electrode on its nerve.
excitation [ek′sitā′shən] Etymology: L, excitare, to arouse

excitation-conduction-contractionin the stimulation of muscle contraction this is the coupling which occurs at the sarcolemma-sarcoplasmic reticulum junction. Mediated by the release of calcium ions in the aqueous sarcoplasm.
excitation-contraction couplingconversion of an excitation stimulus into contraction of the effector muscle fiber; ionic calcium is the link between the two.
indirect excitationelectrostimulation of a muscle by placing the electrode on its nerve.
excitation-secretionin the stimulation of muscular contraction this is the stimulation of secretion of acetylcholine from the vesicles in the cholinergic nerve terminals into the synaptic cleft at the nerve-muscle junction.

Q. I am excited to know in what way diet helps in preventing osteoporosis? my mother is suspecting to be having osteoporosis. She regularly complains of leg pain. Upon consultation with the doctor it was found with low calcium in her blood. She was given calcium tablets and was told to increase in the diet rich in calcium. She is taking milk and yoghurt especially. She is not well yet but shows some improvement. I am excited to know in what way diet helps in preventing osteoporosis?
A. you see, our bones are a giant storage of calcium. our body needs a very steady concentration of calcium, if it'll be low the body will take it form your bones. if there's too much- it'll either build bones (but only if he'll think he needs too- that is where sport get in the picture)or you'll urinate it.any way, you rather have large amount of calcium in your diet then less. but it's not enough- sport and other medication can help.
