anatomy of cerebrum is important for any supratentorial surgical procedures and assessing signs associated with different lobes
Cerebrum
The cerebrum is the largest part of the human brain and consists of two hemispheres separated by the longitudinal cerebral fissure. Each hemisphere has an outer layer of grey matter called the cerebral cortex and an inner mass of white matter. The cortex is highly folded to fit within the skull, forming convolutions called gyri separated by sulci. The cortex can be divided into four lobes - frontal, parietal, temporal and occipital - based on sulci and gyri. Within each lobe are functional areas including motor, sensory, and association areas that control voluntary movement, process sensation, and integrate sensory information respectively.
bordder syurfaces, poles and the Sulci and gyri of cerebrum
The document describes the sulci and gyri of the cerebral hemispheres. It outlines the three surfaces (lateral, medial, inferior), borders, poles (frontal, temporal, occipital), and lobes (frontal, parietal, temporal, occipital) of the hemispheres. It then details the major sulci that divide the cortex into gyri in each lobe, including the central sulcus, lateral sulcus, and parieto-occipital sulcus. Finally, it describes important structures on the medial and inferior surfaces such as the cingulate gyrus, paracentral lobule, and collateral sulcus.
Cerebrum-1.pptx
The cerebrum is the largest part of the human brain and fills most of the cranial cavity. It is a bilobed structure separated by a cleft called the longitudinal cerebral fissure. Each lobe, called a cerebral hemisphere, has an outer layer of grey matter and an inner core of white matter. The surface of each hemisphere is folded into convolutions separated by fissures called gyri and sulci, respectively, which allow the brain to accommodate more surface area in the limited skull space. The hemispheres are divided into four main lobes - frontal, parietal, temporal, and occipital - based on prominent sulci and imaginary boundary lines.

The brain is one of the most complex organs in the human body. It controls muscle movements, gland secretions, breathing, temperature regulation and processes sensory data. The brain develops from the neural tube which forms the three primary brain vesicles - forebrain, midbrain and hindbrain. These vesicles further differentiate into the structures of the adult brain. The major parts of the adult brain are the cerebrum, cerebellum and brainstem. The cerebrum is divided into two hemispheres and four lobes. It controls higher functions such as emotion, memory and speech. The brain also contains ventricles that produce cerebrospinal fluid and structures such as the basal ganglia and diencephalon.

The brain is one of the most complex organs in the human body. It controls muscle movements, gland secretions, breathing, temperature regulation and processes sensory data. The brain and spinal cord begin as an embryonic structure called the neural tube which forms the three primary brain vesicles - forebrain, midbrain and hindbrain. These vesicles further differentiate into the adult brain structures. The major components of the adult brain are the cerebrum, cerebellum and brainstem. The cerebrum contains lobes, gyri, sulci and ventricles. It also contains white matter, basal ganglia and diencephalon structures like the thalamus.
