The Brain Is The Boss
Brain regulates each and every function of the body whether you realise it or not. The way you eat, drink, walk, breathe- all of it is controlled by the brain. Our five sense organs including sight, taste, smell, touch and hearing are controlled by the brain.
The Brain And The Nervous System In Everyday Life
If the brain is a central system that controls all the information, then the nervous system is like a system that conveys the messages to and from the brain via the spinal cord. The spinal cord runs down the spine till the back bone.
As soon as a part of our body, the hand, for example touches a hot substance, the sensory neurons send a message to the brain. The brain then sends a message to the muscle tissues via the motor neurons to move the hand away.
The Forebrain
The forebrain is the largest part of our brain and also the most complicated. It consists of main grooves and wrinkles. The forebrain consists of the cerebrum which controls our thinking, personality, emotional stability and the ability to feel and move. it is divided into lobes:- 1)Frontal which controls the personality
2)Parietal lobes processes the sensory information such as pressure, touch and pain.
3)Occipital lobe interprets the visual stimuli and information.
4) Temporal lobe helps in the interpretation of sounds and language.
The MidBrain
it acts as a master coordinator of messages going to and from the spinal chord to the brain.
The Hind Brain
The hind brain sits at the back of the brain and contains the pons, cerebellum and medulla. The cerebellum is shaped like a tiny cauliflower and maintains the posture of the body. The pons, medulla and the midbrain make up the brain stem which controls all the involuntary functions of the body such as breathing, heart rate, good pressure, swallowing, digestion, etc.
How The Brain Works
The brain system is divided into the central nervous system which includes the brain and the spinal cord and the peripheral nervous system which consists of the cranial and spinal nerves.
A part of the peripheral nervous system called the autonomic nervous system regulates the involuntary functions of the body which include breathing, swallowing, digestion, etc. The autonomic nervous system further consists of the sympathetic and the parasympathetic nervous system.
The sympathetic nervous system prepares the body for sudden stress by increasing the heart rate and blood pressure. It also stimulates the adrenal glands to release the hormone adrenaline in response to sudden stress.
The parasympathetic nervous system does the exact opposite. It calms the body down. It also helps the digestive track to move along its way so that the body can absorb all the nutrients from food.
