Apical is an adjective that typically refers to the highest or topmost point or part of something. It can describe a characteristic or location that is situated at the apex or tip of an object or organism. This term is often used in various fields, such as anatomy, biology, botany, and medicine.
In anatomy, apical may pertain to the apex or highest point of an organ or structure. For example, the apical pulse refers to the pulse that is felt at the apex of the heart, which is typically located at the fifth intercostal space in the midclavicular line. In dentistry, the apical foramen denotes the small opening at the tip of the root of a tooth, through which nerves and blood vessels enter.
In biology and botany, apical is used to describe the growth or development occurring at the growing tip of a plant or an organism. For instance, in plants, the apical meristem is the region at the tip of a shoot or root where cell division takes place, allowing for growth and development. Apical dominance refers to the phenomenon where the central stem or bud inhibits the outgrowth of lateral branches.
Overall, apical refers to the highest or topmost aspect of something, whether it's an anatomical structure, botanical growth, or positional characteristic in various disciplines.

The word apical has its origins in the Latin word apex (plural apices), meaning summit or peak. In Latin, apex was used to refer to the highest point or tip of something, such as a mountain or a pointed object. The word apex was then borrowed into English, and apical was formed by adding the suffix -al, which denotes relating to or of the nature of something. Therefore, apical ultimately means pertaining to or located at the apex or tip.
