Basal area is the cross-sectional area of trees at breast height (1.3m or 4.5 ft above ground). It is a common way to describe stand density. In forest management, basal area usually refers to merchantable timber and is given on a per hectare or per acre basis. If one cut down all the merchantable trees on an acre at 4.5 feet (1.4 m) off the ...

For example, while basal cells in both the esophagus and the stomach function as multipotent progenitor cells, they are fundamentally different because the esophageal basal cells exist as a part of a stratified squamous epithelium, whereas the gastric basal cells exist as a part of a simple columnar epithelium. Functionally, this means that ...
The interpeduncular cistern (or basal cistern [1]) is the subarachnoid cistern situated between the dorsum sellae (anteriorly) [2] and the two cerebral peduncles [1] [3] [2] at the front of the midbrain. [3] Its roof is represented by the floor of the third ventricle (i.e. posterior perforated substance, and the two mammillary bodies).

Platybasia is also a feature of Gorlin-Goltz syndrome, commonly known as basal cell nevus syndrome. It may be developmental in origin or due to softening of the skull base bone, allowing it to be pushed upward.
