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.
Vocal cord: One of two small bands of muscle within the larynx. These muscles vibrate to produce the voice. We use the larynx when we breathe, talk, or swallow. Each time we inhale (breathe in), air goes into our nose or mouth, then through the larynx, down the trachea, and into our lungs.
