Brain Part...Cerebrum and its Functions
Posted in 2015
Cerebrum
The cerebrum constitutes the largest part of the human brain. It is also known as the cortex and is responsible for performing a great number of important brain functions, including action and thought processing. The cerebrum is further subdivided into four different sections that have their own respective functions and are termed as lobes. The names of these lobes are; frontal lobe, occipital lobe, parietal lobe and temporal lobe.
Frontal Lobe: The frontal lobe is tasked with the duty of performing functions like expressive language, reasoning, higher level cognition and motor skills. It is positioned at the front portion of the brain. Any damage to it can lead to changes of socialization, attention, sexual habits, etc.
Parietal Lobe: The parietal lobe is responsible for processing the information sent to the brain by the tactile senses like pain, pressure and touch. It is placed in the center of the brain. Any damage to it can cause problems with language, ability of controlling eye gaze and verbal memory.
Occipital Lobe: The occipital lobe is tasked with the duty of interpreting the information being sent to the brain by the eyes. It is positioned at the back of the brain. If it is damaged, your visual ability will be affected, like unable to recognize colors, words and objects.
Temporal Lobe: The temporal lobe is responsible for forming memories and processing the sounds being recorded by the ears. It is placed at the bottom of the brain. Any damage to it can cause problem with language skills, speech perception and memory.
It causes the functions our eyes, ears, ability to learn....Your child's Brain is developed before birth....Please note the following
My advise
1. The cerebrum, also known as the forebrain, is the largest part of the brain. It is derived embryologically from the telencephalon. The cerebrum consists of two cerebral hemispheres (right and left) separated by a deep longitudinal fissure which contains the corpus callosum. It is enveloped inside thin but protective membranes called meninges, one of which houses the subarachnoid space filled with cerebrospinal fluid.
2... The frontal lobe is the most anterior part of the cerebrum. It is involved in activities like muscle control, higher intellect, personality, mood, social behaviour, and language. Posteriorly, the frontal lobe is separated from the parietal lobe by the central sulcus (of Rolando) and inferiorly from the temporal lobe by the lateral sulcus (of Sylvius). The most significant convolutions of the frontal lobe are the precentral, superior, middle, inferior and orbital. The entire frontal lobe is supplied by the anterior and middle cerebral arteries, which are branches of the internal carolid artery
3... .The panetal lobe is situated between the frontal and occipital lobes, and separated from them by the central and parieto-occipital sulci respectively. It is involved in language and calculation, as well as the perception of various sensations such as touch, pain, and pressure. The lobe consists of two parts called lobules (superior and inferior) separated by an intraparietal sulcus. Other important landmarks include the postcentral sulcus together with the postcentral, angular, and supramarginal gyri. The parietal lobe is supplied by branches of the anterior, middle, and posterior cerebral arteries. The latter originates from the basilar artery
4.... Continuing down the list, we have another lobe of the cerebrum called the temporal lobe. It is responsible for memory, language and hearing. It sits underneath the previous two lobes, from which it is separated by the lateral sulcus. The temporal lobe consists of the superior, middle, and inferior temporal gyri that are delimited by the superior and inferior sulci. It is supplied by the middle and posterior cerebral arteries.
5.. The occipital lobe is the most posterior portion of the cerebrum and it is involved in processing visual stimuli. It rests on the tentorium cerebelli, a fold of dura mater that separates it from the cerebellum. The occipital lobe is separated from the parietal and temporal lobes by the parieto-occipital and calcarine sulci respectively. Additional important features and landmarks include the superior and inferior occipital gyri (divided by the lateral occipital sulcus), lingual gyrus and the cuneus. The vascular supply of the occipital lobe stems from the posterior cerebral artery.
6... Last but not least, we have the insula or insular lobe which is buried beneath the frontal, parietal, and temporal lobes. This lobe is involved in processing various sensations such as taste, pain, visceral and vestibular function. The central sulcus of the insula divides its surface into short and long gyri. This lobe is supplied by branches of the middle cerebral artery.
7.. The brain has to be developed before birth with sufficient water and oxygen. If you supply it your child will be brilliant.
