Preoccipital notch
Preoccipital Notch is a anatomical landmark found on the human skull. It is located on the inferolateral aspect of the occipital lobe, marking the boundary between the temporal lobe and the occipital lobe.
Etymology[edit]
The term "preoccipital" is derived from the Latin words "prae" meaning "before" and "occipital" referring to the occipital bone in the skull. The term "notch" is derived from the Old English "noc" meaning "a notch, a hollow or a deep cut".
Anatomy[edit]
The preoccipital notch is located on the inferolateral aspect of the occipital lobe, marking the boundary between the temporal lobe and the occipital lobe. It is a significant landmark in neuroanatomy as it helps in identifying the parieto-occipital sulcus on the medial surface of the brain.
Clinical Significance[edit]
The preoccipital notch is used as a landmark in neurosurgery, particularly in procedures involving the occipital lobe. It is also used in the diagnosis and treatment of conditions such as epilepsy and brain tumors.
