What's the difference between junction and punction?
Junction
Definition:
(n.) The act of joining, or the state of being joined; union; combination; coalition; as, the junction of two armies or detachments; the junction of paths.
(n.) The place or point of union, meeting, or junction; specifically, the place where two or more lines of railway meet or cross.

(18) In vivo, the ability of an AChR clustering stimulus to depress cluster formation elsewhere on the muscle cell may influence both the site at which the neuromuscular junction develops as well as which axons survive during synapse elimination.
(19) Immunofluorescence and immunoelectronmicroscopy experiments demonstrated that while tight junctions demarcate PAS-O distribution in confluent cultures, apical polarity could be established at low culture densities when cells could not form tight junctions with neighboring cells.
(20) PTH, an inducer of shape change, did not affect the number of gap junctions appreciably.
Punction
Definition:
(n.) A puncturing, or pricking; a puncture.
Example Sentences:
