A hiccup occurs when the diaphragm is thrown into spasms.
When you swallow and hiccup at the same time, the normal swallowing motion can be interrupted by the involuntary contraction of the diaphragm that occurs during a hiccup. This can cause an uncomfortable sensation in the throat or chest. It is a rare occurrence and typically resolves on its own.
The sound of a hiccup is caused by the sudden closure of the vocal cords in the larynx (voice box). This closure occurs as a reflex response to the involuntary contraction of the diaphragm muscle.
No, diffusion does not occur because of random molecular movement. It is rather as a result of movement of molecules from areas of high concentration to lower concentration.
When a movement occurs in two planes, it is called turbulence.
Movement within the cell occurs by microtubules, which act like railroads to help transportation of vessicles and organelles. Movement of the cell itself occurs by either the cilia or the flagella.
