Largest Part of the Brain
The largest part of the brain is the cerebrum which is also known as cortex or telencephalon. It is associated with higher brain functions like thought and action. It makes up about two-thirds of the total mass of the brain. It is situated at the top of the brain and has pons, medulla oblongata, and cerebellum located underneath it. This part consists of two cerebral hemispheres developed from the embryonic forebrain. The main function of the cerebrum is to integrate complex sensory and neural functions. It plays an important role in the process of learning and memorizing things.
Quick Facts: –
- The cerebral cortex is the outermost layer of the cerebrum which is made up of the gray matter.
- It is composed of six thin layers of neurons and is highly convoluted. It has approximately 10 billion neurons.
- It has total four lobes which are frontal lobe, parietal lobe, temporal lobe and occipital lobe.
- The frontal lobe has the control centers for motor activity and speech, the parietal lobe has for sensing touch and position, the temporal lobe has for auditory reception and memory and lastly, the occipital lobe has for visual reception.
- Cerebrum takes information from sensory organs and then interprets it.
- It is few centimeters thick and has a surface area of about 2,000 square centimeters.
- The left hemisphere of the cerebrum is functionally dominant and controls your language and speech.
- Both the hemispheres are connected by a thick band of white matter called the corpus callosum.
- The cerebrum receives sensory information from the peripheral nervous system with the help of nerve connections with brainstem and spinal cord.
- The left hemisphere of the human brain relates to the right side of the body and right hemisphere related to the left side of the body.
