Muscle contraction ends when calcium ions are pumped back to the sarcomere. During stimulation of the muscle cell, the motor neuron releases the neurotransmitter acetylcholine which travels across the neuromuscular junction (the synapse between the terminal bouton of the neuron and the muscle cell).
Hellebore. Helleborus. Hellebores are so easy and so pretty, they have a place in nearly every landscape. Their exquisite bowl-or saucer-shape flowers in white (often speckled), pinks, yellows, or maroon remain on the plant for several months, even after the petals have fallen.

Grow hellebores in shade where soil remains moist; some hellebores prefer acid or alkaline conditions, depending on variety.
