armhead

Armhead is not a standard or widely recognized term in anatomy or engineering. In practice, it may be encountered as a colloquial or context-specific label rather than a formal name, and its meaning depends on the field and the author.

In anatomy, some texts or practitioners might colloquially refer to the “arm head” as the humeral head—the rounded proximal end of the humerus that forms the ball part of the shoulder joint. In formal anatomical terminology, this structure is called the head of the humerus. The humeral head articulates with the glenoid cavity of the scapula and is stabilized by the rotator cuff muscles and surrounding ligaments. When discussed in clinical imaging or surgery, health professionals typically use the precise term rather than “arm head.”

In robotics and mechanical design, “armhead” may be used to describe the interface at the end of an articulated arm where a tool, sensor, or camera is mounted. However, it is not a standardized term in robotics catalogs or standards, and its meaning can vary by manufacturer. Some designers may use it as a shorthand for the end-effector housing or the termination point of an arm assembly, but such usage is inconsistent.

In branding or product naming, “Armhead” can appear as a model name, project codename, or company-specific term, and its interpretation is entirely dependent on the context.
