Question

What is the work of forebrain

Answer 1

Hey friend here is your answer.....


The Forebrain :

This is the anterior part of the brain . The cerebrum forms the largest part of the forebrain, or rather of the entire brain . it is divided into two halves - the right and left cerebral hemispheres . The cerebral hemispheres are shaped somewhat like Kidneys, and or partially separated from each other by a deep groove . their outer surface is full of folds , which increase the surface area and help accommodate the maximum number of neurons . The cell bodies of most of the neurons are located in the upper layers of the cerebral hemispheres, giving these layers a greyish appearance . So, the cell bodies are called grey matter . The axons mostly myelinated of these neurons form bundles that appear white, and are thus called white matter . White matter is mostly found in the deeper  parts of the cerebrum . The interior of the cerebrum has interconnected cavities called ventricles that are filled with cerebrospinal fluid .

The cerebrum is the centre of Intelligence . Different areas of the cerebrum or concerned with learning, memory emotion and reasoning other areas co-ordinate our voluntary activities and make us feel sensation like pain and heat and also control speech and the Census of touch, smell , sight , hearing and taste.  

The hypothalamus a small area of the fore brain is linked to the pituitary gland it controls the endocrine system it also controls many emotional reactions like fear and anger

$\huge\underline\purple{\sf Answer}$

$\huge\red{\boxed{\bold{FORE BRAIN }}}$

✳The brain is mainly divided into three

1) Fore brain

2) Mid brain

3) Hind brain.

✴The main function of fore brain is to support the following parts.

➡FORE BRAIN ::

✳it is also called as prosencephalon.

✳Fore brain consists of three parts.

a) Olfactory bulb.

b) Cerebrum

C) Diencephalon

Olfactory bulb ::

➡ Olfactory bulbs receive impulses pertaining to smell from olfactory epithelium.

Cerebrum ::

➡Cerebrum forms major part of brain.

and it is divided into the left and right cerebral hemispheres by a deep cleft called longitudinal fissure.

➡The two cerebral hemispheres are connected by corpus callosum.

➡This part helps in receive and interpreting impulses and also helps in memory and communication.

Diencephalon ::

➡IT consists of three parts.

1) Epi Thalamus 2) Thalamus 3) Hypo Thalamus.

1. Epithalamus :

✳It forms the roof of diencephalon.

✳Behind the epithalamus there is a pineal body which is stalk like structure.

2. Thalamus :

✳It is a major coordinating centre for sensory and motor signalling.

3.Hypothalamus:

✳It is called thermostat of body.

✳These secrete many hypothalamic hormones.

✳It controls activities like osmoregulatory,, thermoregulatory,, thirst,, Hunger .
