Calcium ions bind to synaptic vesicles, triggering vesicle fusion with the cell membrane and subsequent neurotransmitter release from the motor neuron into the synaptic cleft. Elizabeth Anness is a staff nurse; Kelly Tirone is an assistant nurse manager. Subtle changes in findings may indicate the need for further testing. The NIH Stroke Scale has many caveats buried within it. Usually, a GCS of 8 or less indicates severe brain insult; the patient may be unable to maintain an airway, may require airway protection or even intubation, and may need to go to the intensive care unit for airway monitoring.

Pupil evaluation includes assessment of pupil size, shape, and equality before and after exposure to light. The anterior and posterior spinal veins and anterior and posterior radicular veins are freely communicate with the internal vertebral plexus in the epidural space.
