Most famous parts of the brain highlighted in different colours The human brain anatomical regions are ordered following standard neuroanatomy hierarchies. Functional , connective , and developmental regions are listed in parentheses where appropriate.
The insular cortex is divided into two parts: the larger anterior insula and the smaller posterior insula in which more than a dozen field areas have been identified. The cortical area overlying the insula toward the lateral surface of the brain is the operculum (meaning lid). The opercula are formed from parts of the enclosing frontal ...
The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
The dorsal body cavity includes the cranial cavity, enclosed by the skull and contains the brain, and the spinal cavity, enclosed by the spine, and contains the spinal cord. [1] The ventral body cavity includes the thoracic cavity, enclosed by the ribcage and contains the lungs and heart; and the abdominopelvic cavity.
The human gallbladder is a hollow grey-blue organ that sits in a shallow depression below the right lobe of the liver. [2] In adults, the gallbladder measures approximately 7 to 10 centimetres (2.8 to 3.9 inches) in length and 4 centimetres (1.6 in) in diameter when fully distended. [3]
The posterior view contains, from superior to inferior, the cervical region encompassing the neck, the scapular region encompassing the scapulae and the area around, the dorsal region encompassing the upper back; the lumbar region encompassing the lower back. the sacral region occurring at the end of the spine, directly above the buttocks.
The lowermost (or ventral) region forms the basal nuclei, and contains fibres connecting the rest of the cerebrum to the thalamus. Above this, and forming the lateral part of the cerebrum, is the paleopallium , while the uppermost (or dorsal) part is referred to as the archipallium .
The superior parietal lobule contains Brodmann's areas 5 and 7. Behind it is the lateral part of the parieto-occipital sulcus, around the end of which it is joined to the occipital lobe by a curved gyrus, the arcus parietooccipitalis. Below, it is separated from the inferior parietal lobule by the horizontal portion of the intraparietal sulcus.
