Question

Identify the following structures on a mammalian brain and know their function:

1. Parietal lobe

2. Frontal lobe

3. Occipital lobe

4. Temporal lobe

5. Hypothalamus

6. Pons

7. Cerebellum

Answer 1

Human nervous system divided into two parts 1) The central nervous system 2) The peripheral nervous system .

The central nervous system includes brain and spinal cord. Brain can be divided into three major parts called  fore brain , mid brain , hind brain .  The fore brain consists of olfactory bulb , cerebrum , diencephalon.

Cerebral hemisphere of the cerebrum is divided into four lobes,  they are frontal , parietal, temporal , and occipital lobes .

Frontal lobe allows you to solve a complex task , voluntary movements of your body parts .

Temporal lobes ,  there are two temporal lobes , one in each hemisphere . The main function of this is auditory processing,  emotion and learning , learning a new language .

Parietal lobe main function is general sensation and feeling. It is found in between the frontal and occipital lobe .

Occipital lobe is found back of the cerebrum , and play important role in visual information .

Hypothalamus, it lies at the base of the thalamus . It also contains several groups of neurosecretory cells , which secrets hormones called hypothalamic hormones. Hypothalamus controls and regulates the activities of the autonomous nervous system , and it has osmosis regulatory, thermo regulatory , thirst , feeding and satiety centers .

Pons , it lies in front of the cerebellum below the mid brain and above the medulla ablongata. Pons has the pneumotaxic center in the control of the respiratory muscles as it regulates the amount of air a person can take in , each time .

Cerebellum , it is the second largest part of brain . Cerebellum is responsible for the control and coordination of locomotor movements , it also maintain equilibrium of the body .
