Document Summary
Neurocranium: calvaria (skull cap) + sutures temporal bone: petrous part internal rock like, houses middle and inner ears, mastoid process. Rough because serves for muscle attachment (sternocleidomastoid), muscles that move the c spine and the craniocervical junction. For internal carotid artery: foramen lacerum covered with cartilage during life. Ica crosses over it, junction between temporal, sphenoid and part of occipital, medial border. Jugular foramen junction between temporal and occipital, medial + posterior. Neurocranium: calvaria (skull cap) + sutures occipital bone (4 parts, 1 squamous, 2 lateral, 1 basal: basiocciput (x1) = basillar part . Lateral part (x2) with occipital condyles articulate with superior articulating facets of c1 (atlas) @ atlantoccipital joint. Internally - has matching features = internal occipital protuberance + internal occipital crest. Plus grooves for dural sinuses e. g. transverse dural sinus for venous drainage of the brain: foramen magnum everything develops around it, where brain stem becomes the spinal cord.
