Hi hive how are you? I am fine . I hope all of you are fine and enjoy your life with good health 😊. Today my topic or my diagram is about brain. Brain is the most important part of the human . Human brain has 3 main parts
First is Forebrain second one is midbrain and the third name is hindbrain . Forebrain is the largest part of the brain . Al parts have sub division . Millions of neurons present in the brain. All perform their function very well. Spinal cord create a link between brain and different part of the body.
Human brain is enclosed in a bony skull called cranium and consist of billions of neurons
Forebrain:
Forebrain is the largest part of the brain. It consist of three subdivisions called Cerebrum thalmus and hypothalamus. Cerebrum is upper and largest part of the forebrain. It is divided into two hemispheres. Each hemispheres control the different part of the body.
In general the left hemisphere controls speech, comprehension, arithmetic and writing. The right hemisphere controls creativity, spatial ability , artistic, and musical skills inside cerebrum there is a small structure called thalamus. It controls many sensory functions. Hypothalamus lies at the base of thalamus. It controls body temperature 🌡️, hunger and thirst.
Midbrain
Midbrain is a small part of the brain which is present below the cerebrum. It received information from sense organs which is then passed to the appropriate part of the forebrain.
Hindbrain
Hindbrain consists of three parts, i.e., cerebellum , pons and medulla oblongata.
Cerebellum
Cerebellum control balance of the body. It also muscle movement. It also control motor learning
Pons
It acts as a bridge between different parts of the brain. It also regulate sleepwake cycle. Pons also contain
Cerebellum lies under the back part of the cerebrum. It acts as a controller for maintaining the body balance and making precise and accurate movement.
Medulla oblongata
Medulla oblongata forms the posterior part of the brain where it is connected with the spinal cord. Medulla oblongata controls heart beat , breathing and digestion etc
Spinal cord is an extension of medulla oblongata it runs backwards inside the backbone up to its lower end. It also made up of inter neurons.
Spinal cord create a link between brain and different body parts it also controls some reflex actions and some involuntary actions
