HUMUN BRAIN
The brain is the most important and complex organ in the human body.
It regulates the body's temperature, thoughts, memories, emotions, movements, senses, and
breathing. An average adult brain weighs 1.3–1.4 kg and contains around 100 billion
neurons, which are the cells, responsible for sending messages.
The brain is unique because it enables humans to learn, reason, imagine, and feel emotions.
Without a functioning brain, all other organs cannot function effectively.Diagram:
Structure of the Brain
The brain has three main parts:
The cerebrum controls the brain, memory, speech, and voluntary movement all at the same
time. Balance, coordination, and fine motor skills are all controlled by the cerebellum.
Brainstem(Medulla oblangata) – connects the brain to the spinal cord and controls
automatic functions like breathing and heartbeat.
Each part has specific roles, but they work together to maintain body function.
, Meninges, the skull, and cerebrospinal fluid all provide protection for the brain.
The Cerebrum:The largest part of the brain is the cerebrum, which is divided into two
hemispheres. There are four lobes in each hemisphere: Thinking, planning, finding solutions to
problems, and voluntary movement are all functions of the frontal lobe. The Parietal Lobe is
where information about touch, temperature, and pain is received. The temporal lobe is
involved in speech, memory, and hearing. Visual information is processed by the occipital
lobe. The corpus callosum, which connects the hemispheres, facilitates communication
