Changes at puberty: 

 Sudden increase in height. 

 Broadening of shoulders and widening of chest in boys. In girls, the region below waist becomes wider. 

 At puberty, the voice box or the larynx begins to grow. Boys develop larger voice boxes. The growing voice box in boys can be seen as a protruding part of the throat called Adam’s apple. In girls, the larynx is hardly visible from the outside because of its small size. Generally, girls have a high pitched voice, whereas boys have a deep voice.
