Occipital Bone Segmented Model

説明

This is high detailed segmented model. Size 33 MB without zip. The occipital bone is a single, trapezoid-shaped bone located at the lower and posterior (back and base) part of the skull. It is a crucial cranial bone as it forms part of the skull base, protects the cerebellum, and contains a large opening that allows the spinal cord to connect with the brain.The occipital bone has a complex shape with several distinct parts and important landmarks: Foramen Magnum: This is the most prominent feature of the occipital bone. It's a large, oval-shaped opening located in the inferior (bottom) part of the bone. This foramen serves as the primary passage for: The spinal cord (connecting with the medulla oblongata of the brainstem). The vertebral arteries (supplying blood to the brainstem and cerebellum). The spinal accessory nerves (CN XI). Basilar Part (Basiocciput): This is the stout, anterior portion of the occipital bone that extends forward from the foramen magnum. It articulates anteriorly with the sphenoid bone (specifically the body of the sphenoid) at a cartilaginous joint (synchondrosis) in children, which typically fuses in adulthood. It contains the pharyngeal tubercle, an attachment point for the pharyngeal raphe. Lateral Parts (Condylar Parts): These are located on either side of the foramen magnum. They feature the occipital condyles, which are two kidney-shaped, convex articular surfaces that articulate with the superior articular facets of the atlas (C1 vertebra)…
