A split is basically a nuc, but is taken from a full sized hive and can be made for two main reasons. It is often used as a starter for another hive, to make an increase in holdings, or can be used as a means of population control, supposedly to prevent swarming.
Medical Definition of Larynx. Larynx: A tube-shaped organ in the neck that contains the vocal cords. The larynx is about 5 cm (2 in.) long. It is part of the respiratory system and is located between the pharynx and the trachea. Humans use the larynx to breathe, talk, and swallow.
The larynx is a major (but not the only) source of sound in speech, generating sound through the rhythmic opening and closing of the vocal folds. To oscillate, the vocal folds are brought near enough together such that air pressure builds up beneath the larynx.
