Question

Write the names of the regions of hind-brain. Give functions of each region.Write answers of the given question.

Answer 1

Many of the involuntary actions are controlled by the hind-brain. Hind-brain consists of Medulla, Cerebellum and Pons. All these involuntary actions including blood pressure, salivation and vomiting are controlled by the medulla in the hind-brain. Activities like walking in a straight line, riding a bicycle, picking up a pencil are possible due to a part of the hind-brain called the cerebellum. It is responsible for precision of voluntary actions and maintaining the posture and balance of the body. The pons have been associated with the control of sleep cycles. Additionally, the pons is also associated with the brain stem and the things it controls like respiration and reflexes.

Answer 2

(A) the regions of hind brain:-
1. $\bf{Medulla}$ - It controls various involuntary activities like breathing, heartbeat, peristalsis movement of alimentary canal, blood pressure.
It also controls the main centre of reflex action like coughing, sneezing, vomiting, etc.
2. $\bf{Cerebellum}$ - It maintains the balance of body and postures.
3. $\bf{Pons}$ - It regulates the process of respiration.

(B) The cerebrum has 4 lobes. Each lobe performs specific functions:
1. $\textbf{Occipital lobe}$ - performs the function of visual reception (to see).
2. $\textbf{Temporal lobe}$ - performs the function of auditory reception (to hear)
3. $\textbf{Parietal lobe}$ - performs the function of reception of general smell, touch and temperature.
4. $\textbf{Frontal lobe}$ - controls specific muscular activities like thought, speech and memory
