Base Of The Skull
The base of skull, also known as the cranial base or the cranial floor, is the most inferior area of the skull. It is composed of the endocranium and the lower parts of the calvaria. Structure Structures found at the base of the skull are for example: Bones There are five bones that make up the base of the skull: *Ethmoid bone * Sphenoid bone * Occipital bone *Frontal bone *Temporal bone Sinuses *Occipital sinus * Superior sagittal sinus *Superior petrosal sinus Foramina of the skull * Foramen cecum *Optic foramen *Foramen lacerum *Foramen rotundum * Foramen magnum * Foramen ovale *Jugular foramen *Internal auditory meatus *Mastoid foramen *Sphenoidal emissary foramen *Foramen spinosum Sutures *Frontoethmoidal suture *Sphenofrontal suture *Sphenopetrosal suture *Sphenoethmoidal suture * Petrosquamous suture *Sphenosquamosal suture Other *Sphenoidal lingula *Subarcuate fossa *Dorsum sellae *Jugular process *Petro-occipital fissure *Condylar canal * Jugular tubercle * ...

Anatomical Terms Of Location
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...
