Facial feminization surgery the lower lip and is at the edges of the chin. Males tend to have a much more prominent Adam's apple than females following puberty. The Adam's apple can be reduced with a procedure called a chondrolaryngoplasty; the goal of the procedure is to reduce the size without leaving a scar. There are risks of damage to the vocal cords and destabilization of the epiglottis. Beautification and rejuvenation procedures are often performed at the same time as facial feminisation. For example, it is common for eye bags and sagging eyelids to be corrected with a procedure called "blepharoplasty" and many
Henneman's size principle in this experiment. Experiments were done on 1- to 7-day-old Wistar rats and 20- to 30-day-old Wistar rats as well. The 1- to 7-day-old Wistar rats were selected because early after birth, the rats show an increase in cell size. In 20- to 30-day-old Wistar rats, the physiological and anatomical features of oculomotor nucleus motor neurons remain unchanged. Rat oculomotor nucleus motor neurons were intracellularly labelled and tested using electrophysical properties. The size principle applies to the recruitment order in neonatal motor neurons and also in the adult oculomotor nucleus. The increase in size of motor neurons led to a
