Ear Structure and Function
The head is the most significant part of the tool, as a hammer's type and function is defined by the shape and construction of the head. Hammers consist of multiple parts: face, eye, neck, throat, crown, and claw. The striking face is what makes contact with a material or object. Crowed hammer faces drive nails without leaving marks on a surface.The human ear, like that of other mammals, contains sense organs that serve two quite different functions: that of hearing and that of postural equilibrium and coordination of head and eye movements. Anatomically, the ear has three distinguishable parts: the outer, middle, and inner ear.
