The human brain is the central command center of the human nervous system.
It receives signals from the sensory organs of the human body and provides output information to other body parts.
The human brain weighs approximately about 1.4 kilograms and makes up about 2% of the human body weight.
The brain is divided into three regions - Forebrain, midbrain, and hindbrain.
The forebrain includes the cerebrum, hypothalamus, and thalamus. They control reproductive functions, and regulate body temperature, and emotions.
The midbrain is the smallest part and consists of the tectum and tegmentum.
The hindbrain is made up of the cerebellum, medulla, and pons. They coordinate all the necessary life processes such as breathing, heartbeats, sleep, and motor learning.
