In human anatomy, the neurocranium, also known as the braincase, brainpan, or brain-pan, [1] [2] is the upper and back part of the skull, which forms a protective case around the brain. [3] In the human skull, the neurocranium includes the calvaria or skullcap. The remainder of the skull is the facial skeleton.
Where the apex of the petrous temporal meets the squamous temporal, the transverse sinuses lead into sigmoid (S-shaped) sinuses (one on each side). These pass along the articulation between the posterior edge of the petrous temporal bone and the anterior edge of the occipital bones to the jugular foramen , where the sigmoid sinus becomes the ...
The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas). The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into:
The cranial cavity is formed by eight cranial bones known as the neurocranium that in humans includes the skull cap and forms the protective case around the brain. The remainder of the skull is the facial skeleton. The meninges are three protective membranes that surround the brain to minimize damage to the brain in the case of head trauma ...
An increase in impulsivity, risk taking or both is often seen in individuals following frontal lobe damage.The two related terms differ in that impulsivity is a response disinhibition, while risk taking is related to the reward-based aspects of decision-making. [7]
A, B: The early embryo turns onto its left side; B, C: Symmetry is retained by a further left turn in the anterior head region and a compensating right turn in the rest of the body. D, E: Growth of the optic tract leading to the optic chiasma. Colors refer to early embryo: Red=right side, blue=left side, black=dorsal, white=ventral.
The name derives from its position at the back of the head, from the Latin ob, 'behind', and caput, 'head'. The occipital lobe is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex. [1] The primary visual cortex is Brodmann area 17, commonly called V1 (visual one).
It occurs from impact on either side of the head or from side-to-side compression. The fracture typically runs through the petrous portion of the temporal bones and the sella turcica, potentially affecting the pituitary gland. Blood from both ears often indicates this type of fracture, which is the most common basilar skull fracture.
