Parts of the adult navel include the "umbilical cord remnant" or "umbilical tip", which is the often protruding scar left by the detachment of the umbilical cord. This is located in the center of the navel, sometimes described as the belly button. Around the cord remnant is the "umbilical collar", formed by the dense fibrous umbilical ring ...
Diagram of tooth anatomy. Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.)
Umbilical reconstruction can be difficult due to scar tissue and lack of extra skin for surgical use, though this can be overcome by using tissue expanders below the skin and umbilicoplasty. [ 9 ] Ultimately, prognosis depends on the size of the defect and whether associated abnormalities are present or complications develop.
The umbilical region is one of the nine regions of the abdomen. It is the region that surrounds the area around the umbilicus and is placed approximately halfway between the xiphoid process and the pubic symphysis .
The location where the outer enamel epithelium and inner enamel epithelium join is called the cervical loop. [1] The growth of cervical loop cells into the deeper tissues forms Hertwig Epithelial Root Sheath, which determines the root shape of the tooth. During tooth development there are strong similarities between keratinization and amelogenesis.
Bottom teeth of a seven-year-old, showing primary teeth (left), a lost primary tooth (middle), and a permanent tooth (right) Tooth eruption in humans is a process in tooth development in which the teeth enter the mouth and become visible. Current research indicates that the periodontal ligaments play an important role in tooth eruption.

The medial umbilical ligament, cord of umbilical artery, or obliterated umbilical artery is a paired structure found in human anatomy. It is on the deep surface of the anterior abdominal wall , and is covered by the medial umbilical folds ( plicae umbilicales mediales ).
