Question

Draw a neat diagram of the human brain and label any four parts.

Answer 1

Hint: The brain is the coordinating centre of the body and it is made up of many specialised areas that work together. It has 4 lobes frontal, parietal, temporal and occipital lobe and it is majorly divided into cerebrum, cerebellum and brainstem.

Complete answer:

The brain is one of the largest and most complex organs in the human body. It is made up of billions of nerves that communicate in a connection called synapses. Brain is made up of soft tissue, which includes white matter, gray matter, nerve, non- neuronal cells and blood vessels. The brain is made up of many specialised areas that work together, first is the cortex, which is the outermost layer of the brain cell and is responsible for thinking and voluntary movement. The brainstem is present between the spinal cord and the rest of the brain. Basic functions like breathing and sleep are controlled here. The basal ganglia present in the centre of the brain coordinates messages between multiple other brain areas. The cerebellum is present at the base and the back of the brain. The cerebellum is responsible for coordination and balance. Brain is also divided into several lobes-frontal lobe, parietal lobe, temporal lobe and occipital lobe. The brain is surrounded by three layers called meninges. Outside the meninges, the skull or cranium is present that protects the brain from injury. Hypothalamus, thalamus, pituitary gland, pineal gland, amygdala, hippocampus and the midbrain are also the part of the brain.

Note: The main 3 parts of the brain are cerebrum, cerebellum and brainstem. The brainstem is made up of the midbrain, pons and medulla oblongata. Medulla oblongata continues posteriorly with spinal cord.
