Os parietale (Scheitelbein)

The video tutorial provides an in-depth look at the parietal bone, highlighting its rectangular shape and position below the skull's vertex. It explains the concave inner and convex outer surfaces, and the grooves on the facies internals. The tutorial also covers the facies externa, including the superior and inferior temporal lines. It discusses the parietal foramen and its communication with the superior sagittal sinus, as well as the serrated suture between parietal bones. Finally, it details the parietal bone's connections with other cranial bones, such as the OS Frontale and OS occipitale.

What is the shape of the parietal bone and where is it located?

• Circular, at the back of the skull

• Oval, on the sides of the skull

• Rectangular, just below the vertex of the skull

• Triangular, at the base of the skull

Which structure runs through the grooves on the inner surface of the parietal bone?

• Temporal muscle

• Artery mini-media

• Sinus sagittalis

• Fascia temporalis

What is the function of the superior temporal line on the parietal bone?

• Origin of the temporal muscle

• Attachment for the fascia temporalis

• Passage for the emissary veins

• Connection with the occipital bone

Through which foramen does the Wehner Emissary vein communicate with the superior sagittal sinus?

• Foramen magnum

• Jugular foramen

• Optic foramen

• Parietal foramen

Which suture connects the two parietal bones?

• Sutura coronalis
