There are three major brain divisions. They are the cerebrum‚ the brainstem‚ and the cerebellum. The cerebrum contains 40% of the weight of the brain and is founded in the superior part of the brain. This portion of the brain has many functions and lobes which perform certain functions. The frontal lobe is involved with “activating and controlling both fine and complex motor activities.” This involves speech. It is also involved with the executive functions‚ such as reasoning and rationalizing‚ among

shifting to more of the brain development‚ humans and apes have some similarities in this area. Many scientists believe that the human and ape brain evolved unusually rapidly‚ specifically the cerebellum part‚ which involves the control of movement. For scientists to really research and understand how the cerebellum evolved started with researching and investigating other parts of the brain in

The Brain has five major structures . These structures include the mesencephalon‚ metencephalon‚ myelencephalon (or medulla)‚ telencephalon‚ and diecephalon. All of these brain structures contribute different functions within the human body. The brain’s first structure is the myelencephalon‚ which is also called the medulla. The myelencephalon is known as the most posterior part of the brain. The structure of the myelencephalon is made up of bundles of axons called tracts. These tracts carry

exception to this distribution is the ventral wedge of the medulla served by the anterior spinal arteries. The posterior inferior cerebellar arteries continue onto the caudal-medial (inferior) aspect of the cerebellum near the midline and then extend laterally onto the inferior surface of the cerebellum. At the pons-medulla junction‚ the vertebral arteries join to form the basilar artery‚ which then gives off the anterior inferior cerebellar arteries (AICA). This pair of arteries passes laterally around

Long-term memory is the phase or type of memory responsible for the storage of information for an extended period of time. The second part of the brain is the cerebellum. The cerebellum is at the back of the brain and it controls balance‚ movement‚ and coordination (how your muscles work together). Because of the cerebellum‚ you can stand upright‚ keep your balance‚ and move around. The next part of the brain is the brain stem. The brain stem connects the rest of the brain to the spinal

result‚ cerebellum development takes places in this small posterior compartment which leads to overcrowding and not only results in abnormal protrusion of cerebellar tonsils but also its impaction with foramen magnum. This theory has been found to be consistent with the association of Chiari 1 malformation with other hereditary mesodermal connective tissue diseases i.e Ehlers-Danlos syndrome.[6] Pathophysiology leading to symptoms of Chiari 1 are as follows: (A) compression of cerebellum‚ (B) compression
