The brain is composed of 3 main structural divisions: the cerebrum, the brainstem, and the cerebellum (see the images below). At the base of the brain is the brainstem, which extends from the upper cervical spinal cord to the diencephalon of the cerebrum. The brainstem is divided into the medulla, pons, and midbrain.
Which are the three major divisions of the brain?
- Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. ...
- Cerebellum: is located under the cerebrum. ...
- Brainstem: acts as a relay center connecting the cerebrum and cerebellum to the spinal cord.

What are the 6 major divisions of the brain?
1: The six major divisions of the central nervous system. (1) the spinal cord; (2) medulla oblongata, (3) pons , and (4) midbrain [collectively called the brain stem]; (5) diencephalon; and (6) cerebral hemispheres.
What are the 5 major divisions of the brain?
These vesicles ultimately become five brain divisions: Telencephalon, Diencephalon, Mesencephalon (midbrain), Metencephalon, and Myelencephalon . The five brain divisions are convenient for regionally categorizing the locations of brain components.
What is the biggest part of the brain?
The forebrain is the largest and most highly developed part of the human brain: it consists primarily of the cerebrum (2) and the structures hidden beneath it (see “The Inner Brain”). When people see pictures of the brain it is usually the cerebrum that they notice.
What is the largest division of the brain?
The largest part of the brain, the cerebrum has two hemispheres (or halves). The cerebrum controls voluntary movement, speech, intelligence, memory, emotion, and sensory processing.
What are the four major division of the brain?
Each brain hemisphere (parts of the cerebrum) has four sections, called lobes: frontal, parietal, temporal and occipital .
What are the 7 parts of the brain?
Cerebral cortex, Cerebellum, Hypothalamus,Thalamus,Pituitary gland, Pineal gland, Amygdala, Hippocampas and the Mid- brain .
What 2 things does the midbrain control?
Midbrain, also called mesencephalon, region of the developing vertebrate brain that is composed of the tectum and tegmentum. The midbrain serves important functions in motor movement, particularly movements of the eye, and in auditory and visual processing .
What is the most inferior division of the brain?
In vertebrate anatomy, the brainstem is the most inferior portion of the brain, adjoining and structurally continuous with the brain and spinal cord.
What is fore brain?
Forebrain, also called prosencephalon, region of the developing vertebrate brain ; it includes the telencephalon, which contains the cerebral hemispheres, and, under these, the diencephalon, which contains the thalamus, hypothalamus, epithalamus, and subthalamus.
What are the 4 parts of the brain and their functions?
- Frontal Lobe. This section controls attributes, such as reasoning, planning, parts of speech, general movement, emotions, problem-solving, smell and personality.
- Parietal Lobe. ...
- Occipital Lobe. ...
- Temporal Lobe.
What part of the brain controls emotions?
The prefrontal cortex is like a control center, helping to guide our actions, and therefore, this area is also involved during emotion regulation. Both the amygdala and the prefrontal cortex are part of the emotion network.
What part of the brain is responsible for hearing?
Auditory information is analyzed by multiple brain centers as it flows to the superior temporal gyrus, or auditory cortex , the part of the brain involved in perceiving sound. In the auditory cortex, adjacent neurons tend to respond to tones of similar frequency.
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.
