Document Summary

Temporal bones are situated at the sides and base of skull. Sides: plate-like squamous part is directed upwards and laterally, strong zygomatic process is directed forwards, petrous part, triangular in shape, is directed medially, external acoustic meatus, enclosed between squamous and tympanic parts, is directed laterally. Squamous part: two surfaces:outer and inner, two borders: superior and anteroinferior. Outer or temporal: it is smooth and forms a part of temporal fossa, above external acoustic meatus, there is a groove for middle temporal artery, its posterior part presents supramastoid crest. Below the anterior end of supramastoid crest and posterosuperior to external acoustic meatus, there is suprameatal triangle: zygomatic process springs forwards from the outer surface of squamous part, its posterior part comprises superior and inferior surfaces. Inner or cerebral: it is concave and shows grooves for the middle meningeal vessels, its superior border articulates with the lower border of parietal bone, its anteroinferior border articulates with the greater wing of sphenoid.
