Human Brain and it's parts with structure and function

Introduction :- Brain is the most complex and advance part in the human body. So in today article I will tell you the Human Brain and it's parts with structure and function. Learning of Human Brain and it's parts with structure and function is very important, because brain is a important part of CNS(central nervous system),which control all activities of the body. So we studying Human Brain and it's parts with structure and function below. Human Brain and it's parts with structure and function.

Human Brain 

Definition:

The central organ of central nervous system (CNS)which control all activities of the body.

Explanation:

Location of brain :

It lies in a cavity called cranium supported by a protective layer called meninges.

Cranial nerves :

Nerves arising from the brain are called cranial nerves. There is twelve pairs of cranial nerves arising from brain.

Mass of brain :

2% mass of the body is brain.

Mass in Kg :

1.2kg in females.

 1.4kg in mals.

Parts of brain :

Human brain can be divided into three parts.

 - Forebrain 

2nd -Midbrain 

3rd -Hindbrain 

1.Forebrain:

The first part of brain is called forebrain. This is the largest area of the brain. This part is further divided into three parts.

a. Cerebrum

b. Thalamus 

c. Limbic system 

a. Cerebrum : 

This is the largest part of the brain. It is divided into two halves called cerebral hemispheres. These halves are communicate with each other called corpus callosum. 

Function :

1. It is responsible for intelligence, thinking and decision.

2. The speech centre is also present in the Cerebrum.

b. Thalamus :

Thalamus is oval shape structure present in the arc of Cerebrum.

Function :

1. It receives sensory information and carried to Limbic system and Cerebrum.

c. Limbic system :

Limbic system is located in an arc between Thalamus and Cerebrum. It contains 1. Hypothalamus; 2. Amygdala; 3. Hypocampus.

Function :

1. It control the response like hunger,thirst,fear, anger, pleasure and sexual response.

Note :  it the end of hypothalamus pituitary gland is attached.

2. Midbrain :

It is located between forebrain and Hindbrain. It is the smallest part of the brain. 

Function :

1. It connects forebrain with Hindbrain.

2. It also control reflex movement of eye and hearing.

3. Hindbrain :

It is the last part of brain.

It is further divided into three parts.

a. Cerebellum 

b. Pons

c. Medulla oblongata 

a. Cerebellum :

It is the second largest part of brain.

Function :

1. It control balance of the body and coordinate the voluntary movement of the body as well.

b. Pons

:

It is located above medulla oblongata.

Function :

1. It controls transition between sleep and wakefulness and also control rate of breathing.

c. Medulla oblongata :

It is the posterior part of the brain connected with spinal cord.

Function :

1. It control involuntary function like breathing, heart rate, circulation of blood, blood pressure, swallowing and vomiting.

Conclusion :

As we know from the above article Human Brain and it's parts with structure and function and we see that brain in human body is most important because it control all activities of the body. So we need to study Human Brain and it's parts with structure and function
