Underneath the cerebrum lies the brainstem‚ but behind that is where the cerebellum can be located. On the other hand the outermost layer of the cerebrum is the cerebral cortex that happens to contain four lobes which include the frontal lobe‚ parietal lobe‚ temporal lobe‚ and the occipital lobe. However the human brain can be broken

parts: cerebrum‚ cerebellum and brain stem. Cerebrum The cerebrum is the largest part of the brain. It is divided into 2 parts (halves) called the left and right cerebral hemispheres. The 2 hemispheres are connected by a bridge of nerve fibres called the corpus callosum. The right half of the cerebrum (right hemisphere) controls the left side of the body. The left half of the cerebrum (left hemisphere) controls the right side of the body. The outer surface of the cerebrum is called

signals to and from all of the parts of the human body. The brain has three different components that make up its structure and those components are the cerebrum‚ cerebellum‚ and brain stem. Each of theses components can each be broken down into their own individual parts and each of those parts plays a role in carrying out a function of life. The cerebrum is the largest part of the brain and it is divided into the left and right hemispheres while being made up of four different lobes. The four lobes

area of the brain carries signals between the body and the brain. The functions of the myelencephalon include autonomic functions‚ breathing‚ digestion‚ heart rate‚ swallowing‚ and sneezing. The mentencephalon is located under the rear area of the cerebrum and above the medulla oblongata. This structure is made up of the cerebellum and pons (the connection to the cerebellum). The functions of the metencephalon include arousal‚ balance‚ cardiac reflexes‚ muscle movement and maintenance‚ and sleep. Along

Temporal Lobe It is involved in primary auditory perception‚ such as hearing.

It also coordinates the activities of the other parts of the brain. Cerebellum It coordinates voluntary movements such
