Cone‐shaped protuberance on the crown of a tooth that forms the occlusal surface.
Sharp, rigid point.
The pointed tip of a tooth.
A flap of membrane forming a valve in the heart.
Tapered point, especially those on the tops of the teeth.
Any of the cone-shaped prominences on the upper and lower premolar and molar teeth, which interdigitate when the teeth are held together in the normal occlusion.
In anatomical terms, an apex refers to a tapering point, such as the pointed end of a tooth. Additionally, the term is used to describe the flaps of the heart valves. These valve flaps, also known as leaflets, exhibit a tapering shape that enables them to open and close effectively, regulating the flow of blood through the heart. The apex serves as an important structural feature in both dental and cardiac contexts, contributing to the proper functioning of these respective systems.
