The telencephalon (plural: telencephala or telencephalons) is the most anterior region of the primitive brain. Together with the diencephalon, the telencephalon develops from the prosencephalon, the primitive forebrain 1. The inferior boundaries of the telencephalon are found at the diencephalon and brainstem 1.
Which part of the brain is called telencephalon?
The telencephalon is also known as the cerebrum, and it consists of the largest part of the brain (it makes up about 85% of the total weight of the brain).
What is the telencephalon?
The telencephalon, commonly called the cerebral hemispheres, is the largest portion of the central nervous system (CNS) and consists of the cerebral cortex, subcortical white matter (commissural, association, and projection fibers), and basal nuclei.
What occurs in the telencephalon?
From the telencephalon derive the cerebral cortex, basal ganglia, hippocampal formation, amygdala and olfactory bulb. From the diencephalon the thalamus and surrounding nuclei, hypothalamus, retina and optic nerve. The mesencephalon gives rise to the midbrain structures, and the metencephalon the pons and cerebellum.
What is telencephalon and diencephalon?
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 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 main function of the telencephalon?
Movement. The telencephalon is the part of the brain which attributes motor function to the body. These functions originate within the primary motor cortex and other frontal lobe motor area.
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 part of the brain?
The cerebrum (front of brain) comprises gray matter (the cerebral cortex) and white matter at its center. The largest part of the brain, the cerebrum initiates and coordinates movement and regulates temperature.
Is the region of the brain responsible for equilibrium?
Terms in this set (131) - A large portion of the brain posterior to the brainstem and inferior to the cerebrum, responsible for equilibrium, motor coordination, and memory of learned motor skills. - The stalklike lower portion of the brain, composed of all of the brain except the cerebrum and cerebellum.
What is telencephalon made of?
The telencephalon is composed of surface grey matter (the cerebral cortex) and underlying white matter, with deep masses of grey matter 2. The corpus callosum facilitates communication between the two hemispheres 3.
What is an oblongata?
Medulla oblongata, also called medulla, the lowest part of the brain and the lowest portion of the brainstem. ... The medulla oblongata plays a critical role in transmitting signals between the spinal cord and the higher parts of the brain and in controlling autonomic activities, such as heartbeat and respiration.
What is called corpus callosum?
Corpus callosum, bundle of nerve fibres in the longitudinal fissure of the brain that enables corresponding regions of the left and right cerebral hemispheres to communicate. The axons and dendrites of the neurons in the corpus callosum synapse with cortical neurons on symmetrically related points of the hemispheres.
What part of the brain controls memory?
The prefrontal cortex holds recent events briefly in short-term memory. The hippocampus is responsible for encoding long-term memory. Short-term memory, also called working memory, occurs in the prefrontal cortex. It stores information for about one minute and its capacity is limited to about 7 items.
What part of the brain is the seat of intelligence?
The part of the brain in which the seat of intelligence is located is the frontal lobe.
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.
Is the human brain the most complex thing?
The brain is the last and grandest biological frontier, the most complex thing we have yet discovered in our universe. It contains hundreds of billions of cells interlinked through trillions of connections.
Which is the largest part of human body?
The largest internal organ (by mass) is the liver, with an average of 1.6 kilograms (3.5 pounds). The largest external organ, which is also the largest organ in general, is the skin. The longest muscle is the sartorius muscle in the thigh.
Which is the smallest part of brain?
The midbrain is the smallest region of the brain, and is located most centrally within the cranial cavity. Limbic System – the limbic system is often referred to as our “emotional brain”, or 'childish brain'. It is found buried within the cerebrum and contains the thalamus, hypothalamus, amygdala and hippocampus.
At what age is the brain fully formed?
Brain Maturity Extends Well Beyond Teen Years : NPR. Brain Maturity Extends Well Beyond Teen Years Under most laws, young people are recognized as adults at age 18. But emerging science about brain development suggests that most people don't reach full maturity until the age 25.
Which part constitutes the major part of the brain?
The cerebrum, which forms the major portion of the brain, is divided into two major parts: the right and left cerebral hemispheres. The cerebrum is a term often used to describe the entire brain.
How do psychologists study the brain?
To study the brain, psychologists use a variety of tools, like EEG, PET and CAT scans, MRI, DTI, and studying pathology in individuals.
What 2 things does the midbrain control?
- The midbrain or mesencephalon is the forward-most portion of the brainstem and is associated with vision, hearing, motor control, sleep and wakefulness, arousal (alertness), and temperature regulation. ...
- The principal regions of the midbrain are the tectum, the cerebral aqueduct, tegmentum, and the cerebral peduncles.
How does the brain develop?
The human brain develops from the tip of a 3-millimeter-long neural tube. At three to four weeks after conception, the neural groove closes into a tube, and three distinct regions—a hindbrain, midbrain, and forebrain—begin to take form. ... The cerebral cortex is a fascinating object of study from many perspectives.
Is diencephalon part of brain?
In adults, the diencephalon appears at the upper end of the brain stem, situated between the cerebrum and the brain stem. It is made up of four distinct components: the thalamus, the subthalamus, the hypothalamus, and the epithalamus.
