The cerebellum is the second largest part of the brain. It sits below the posterior (occipital) lobes of the cerebrum and behind the brain stem, as part of the hindbrain. Like the cerebrum, the cerebellum has left and right hemispheres. A middle region, the vermis, connects them.
What are the 3 largest parts of the brain?

- Cerebellum: is located under the cerebrum. …
- Brainstem: acts as a relay center connecting the cerebrum and cerebellum to the spinal cord.

Which side of the brain controls memory?
Our brains have two sides, or hemispheres. In most people, language skills are in the left side of the brain. The right side controls attention, memory, reasoning, and problem solving.
What makes up 80% of the human brain?
80% of the brain volume is made up of glial cells. In terms of volume, brain tissues help in maintaining the metabolic activity of the human body. Most of the energy to the brain is supplied from glucose. Different information from various parts of the body are processed inside the brain.
Does the brain feel pain?
The brain itself does not feel pain because there are no nociceptors located in brain tissue itself. This feature explains why neurosurgeons can operate on brain tissue without causing a patient discomfort, and, in some cases, can even perform surgery while the patient is awake.
Which is the smallest part of human brain?
Midbrain. The midbrain is often considered the smallest region of the brain. It acts as a sort of relay station for auditory and visual information. The midbrain controls many important functions such as the visual and auditory systems as well as eye movement.
What is the largest part of the body?

Which lobe of the brain deals with sound?
Anatomical terms of neuroanatomy
The auditory cortex is the part of the temporal lobe that processes auditory information in humans and many other vertebrates. It is a part of the auditory system, performing basic and higher functions in hearing, such as possible relations to language switching.
