Like the cerebral cortex, it has two hemispheres. The outer portion contains neurons, and the inner area communicates with the cerebral cortex. Its function is to coordinate voluntary muscle movements and to maintain posture, balance and equilibrium .
What are the exterior parts of the brain?
The cerebrum has billions of neurons and glia that form the cerebral cortex , its outermost layer. This is commonly known as gray matter. Connection fibers between neurons beneath the surface of the brain are called white matter. The cerebellum, or hindbrain, handles fine motor movements, balance, and posture.
What are the external structures of the brain?
- The major external structures include the cerebral cortex, cerebellum and brainstem.
- Internal structures include the hypothalamus, pituitary gland and corpus callosum.
What are the external structures of the brain stem?
The three components of the brainstem are the medulla oblongata, midbrain, and pons . Brainstem Anatomy: Structures of the brainstem are depicted on these diagrams, including the midbrain, pons, medulla, basilar artery, and vertebral arteries.
What is the outer structure of the brain called?
The outer layer is called the periosteum . An inner layer, the dura, lines the inside of the entire skull and creates little folds or compartments in which parts of the brain are protected and secured. The two special folds of the dura in the brain are called the falx and the tentorium.
What part of the brain is responsible for memory?
The hippocampus is responsible for encoding long-term memory. Short-term memory, also called working memory, occurs in the prefrontal cortex.
When we learn the main change within the brain is in?
When you are learning, important changes take place in your brain, including the creation of new connections between your neurons. This phenomenon is called neuroplasticity . The more you practice, the stronger these connections become.
What is the most important part of the brain?
The brain stem is regarded by many as the most important part of the entire brain and nervous system. It is connected to the spine and carries out the task of sending messages to all parts of the body. Every physical movement in the body is carried out in some capacity from the brain stem.
What is the most important function of the brain?
Anatomy & Function
The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions , allows us to think and feel, and enables us to have memories and feelings—all the things that make us human.
What are the 3 types of the brain?
The brain can be divided into three basic units: the forebrain, the midbrain, and the hindbrain . The hindbrain includes the upper part of the spinal cord, the brain stem, and a wrinkled ball of tissue called the cerebellum (1).
What are the 4 parts of the brainstem?
The brainstem has an ectodermal origin and is composed of 4 parts: the diencephalon, mesencephalon, pons, and medulla oblongata .

Is the amygdala white or gray matter?
The other additional gray matter structure is the amygdala, which is a large mass of gray matter buried in the anterior-medial part of the temporal lobe, anterior to the lateral ventricle and the hippocampus (see Figure 5.10).
What are the 4 parts of the brain and their functions?
Each hemisphere can be divided into four lobes: the frontal lobe, temporal lobe, occipital lobe, and parietal lobe . The lobes are functional segments. They specialize in various areas of thought and memory, of planning and decision making, and of speech and sense perception.
Who named the brain?
From etymological dictionaries, such as the great 32-volume work assembled in the 19th century by the “ brothers Grimm ” we find that the modern word “brain” is derived from the Old English “braegen”, which is the word that still exists in other western Germanic languages, e.g. “brein” in Danish and Friesian.
Who discovered the brain?
Within a few years of each other, the English physician Thomas Willis published his Anatomy of the Brain (1664) and the Danish anatomist Nicolaus Steno published his Lecture on the Anatomy of the Brain (1669).
