One of the biggest and most intricate organs in the human body is the brain.
It consists of more than 100 billion nerves, which connect in trillions in a process known as synapses.
The meninges are a layer of tissue that covers the brain. The brain is protected from damage by the skull (cranium).
Parts of Brain :
Your brain architecture is intricate. There are three main divisions:
1. Your cerebrum interprets sounds, images, and sensations. It also controls thinking, learning, and emotions. About 80% of your brain is made up of your cerebrum.
2. Your cerebellum keeps your balance, posture, coordination, and fine motor skills in tact. It is in the recesses of your brain.
3. Your brainstem controls a number of your body automatic processes. Your heart rate, breathing, sleep and wake cycles, and swallowing are all automatic bodily processes.
Functions of Brain :
Your five senses—sight, smell, hearing, touch, and taste—provide data to your brain. Along with autonomic (involuntary) inputs from your organs, your brain also receives signals from the rest of your body, such as touch, vibration, pain, and temperature. It analyses this data so that you can comprehend and provide meaning to the events taking place around you.
Your brain allows for:
- the ability to feel different feelings, including pain.
- Decisions and ideas.
- emotions and memories.
- Functions of speech and language.
- coordination, balance, and movement
- Response of flight or fight.
- Automatic actions like breathing, heart rate, sleeping
- controlling body temperature.
- controlling how an organ works.
