Pulse
Definition:
(n.) Leguminous plants, or their seeds, as beans, pease, etc.
(n.) The beating or throbbing of the heart or blood vessels, especially of the arteries.
(n.) Any measured or regular beat; any short, quick motion, regularly repeated, as of a medium in the transmission of light, sound, etc.; oscillation; vibration; pulsation; impulse; beat; movement.
(v. i.) To beat, as the arteries; to move in pulses or beats; to pulsate; to throb.
