The human brain. The human brain is the central organ of the human nervous system, and it controls most of the activities of the human body.
An introduction to the human brain: its main parts (cerebrum, cerebellum, brainstem) and key deep structures (hypothalamus, pituitary gland, amygdala, hippocampus) and their functions.
Key Takeaways
- The brain is the control center of the body, coordinating nearly all activities.
- Its three main regions each handle distinct roles: the cerebrum for higher functions, the cerebellum for movement, and the brainstem for connecting to the spinal cord.
- Small deep structures such as the hypothalamus and pituitary gland play outsized roles in regulating the body's internal balance and hormones.
What the video covers
- The brain is the central organ of the nervous system and controls most bodily activities.
- An adult human brain weighs about 1.4 kg and is divided into two hemispheres.
- The brain has three main parts: the cerebrum, the cerebellum, and the brainstem.
- The cerebrum is the largest part, processing sensory information and serving as the center for speech, learning, and emotion.
- The cerebellum, located at the back of the brain, controls movement and balance.
- The brainstem connects the brain to the spinal cord, together forming the central nervous system.
- Beneath the cerebral cortex lie important structures including the hypothalamus, pituitary gland, amygdala, and hippocampus.
- The hypothalamus, though very small, regulates body temperature, blood pressure, hormones, hunger, and thirst.
- The pituitary gland, connected to the hypothalamus, secretes hormones and links the nervous and endocrine systems.
- The amygdala, one in each hemisphere, is primarily responsible for emotions, while the hippocampus is concerned with memory.

Speaker A
A human brain weighs about 1.4 kg and is divided into two hemispheres. The brain consists of three main parts: the cerebrum, the cerebellum, and the brainstem.
Speaker A
The cerebrum is the largest part of the brain. It processes information from what we touch, see, and hear.
Speaker A
It's also the center for speech, learning, and emotion. The cerebellum is the part at the back of your brain. It controls movement and balance.
Speaker A
The brainstem connects the brain and the spinal cord, which together make up the central nervous system.
Speaker A
Underneath the cerebral cortex, are several important structures, including the hypothalamus, the pituitary gland, the amygdala, and the hippocampus.
Speaker A
The hypothalamus is very small, but it regulates body temperature, blood pressure, and hormones, and controls hunger and thirst.
Speaker A
The pituitary gland is connected to the hypothalamus. It secretes hormones and links the nervous and endocrine systems.
Speaker A
There is one amygdala in each hemisphere of the brain. They are primarily responsible for emotions.
Speaker A
The hippocampus is concerned with memory. What other structures of the brain can you name?
Speaker A
Can you describe their main functions? [Music]
