  A fat pad (aka haversian gland) is a mass of closely packed fat cells surrounded by fibrous tissue septa. They may be extensively supplied with capillaries and nerve endings.
  
  Examples are:
  
  * Intraarticular fat pads. These are also covered by a layer of synovial cells. A fat pad sign is an elevation of the anterior and posterior fat pads of the elbow joint, and suggests the presence of an occult fracture.
  * Buccal fat pad can be seen in nursing babies.
  * The fat pad of the labia majora, which can be used as a graft, often as a so-called "Martius labial fat pad graft", which can be used, for example, in urethrolysis.
  * Fat pads within the heels which when they get inflamed can cause heel pad syndrome
  * The pads under the balls of the feet.
  * The eight pairs of focal fat pads running from the armpit to the groin found in all lean women and men in a curved linear arrangement identical to the mammary ridge lines seen in human embryos.
