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.
Larynx, also called voice box, a hollow, tubular structure connected to the top of the windpipe (trachea); air passes through the larynx on its way to the lungs. The larynx also produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts. The larynx is composed of an external skeleton of cartilage plates that prevents collapse of the structure. The plates are fastened together by membranes and muscle fibres.
