Extra Questions for Chapter 7 Science Control and Coordination

Q.1. Which part of the human brain is the most developed?

Solution 

The forebrain is the largest part of the human brain. It is divided into two parts the right cerebrum and the left cerebrum. The two cerebral hemispheres are joined by the corpus callosum. It has sensory areas like frontal lobe, parietal lobe, temporal lobe, occipital lobe, olfactory lobe. These areas are specific for the interpretation of stimulus received by the effector organs. Thus, it is considered as the most developed part of the brain. 

Q.2. Write a short note on the midbrain.

Solution

Midbrain is located between the thalamus region of the forebrain and pons region of the hindbrain. It helps in the relay of information from the hindbrain to the midbrain. The dorsal surface of midbrain consists of superior and inferior corpora bigemina and four round lobes called corpora quadrigemina. A canal known as cerebral aqueduct passes through the midbrain. The midbrain is concerned with the sense of sight and hearing.

Q.3. Write a short note on hindbrain.

Solution

Hindbrain consists of three regions pons, cerebellum, and medulla oblongata.

(0) Pons is a band of nerve fibres that lies between the medulla oblongata and midbrain. It helps to regulate several involuntary processes like respiration etc.

(ii) The cerebellum is a large and well-developed part of the hindbrain. It regulates motor movement which maintains posture, balance, coordination, and speech. (iii) The medulla oblongata is the posterior and simplest part of the brain. It is located beneath the cerebellum; its lower end extends in the form of the spinal cord and leaves the skull through the foramen magnum.

Q.4. Distinguish between cerebrum and cerebellum.

Solution

The cerebrum is the part of the forebrain. Cerebrum serves to receive sensory inputs, to bring about integration before commanding voluntary motor responses, to coordinate the activities of another part of the brain, and to carry out higher thought processes for learning, memory, language, and speech.

The cerebellum is part of the hindbrain. Cerebellum serves to coordinate the voluntary movements of skeletal muscles as well as posture, balance, and equilibrium.
