Differentiate between: (a) Myelinated and non-myelinated axons (b) Dendrites and axons (c) Thalamus and Hypothalamus (d) Cerebrum and Cerebellum
Match the following brain parts with their characteristic features, location, or primary functions as described in NCERT. Column I (Brain Part) (i) Cerebrum (ii) Thalamus (iii) Hypothalamus (iv) Midbrain (v) Medulla oblongata Column II (Characteristic/Location/Function) (P) Contains centers controlling body temperature, urge for eating and drinking. (Q) A major coordinating centre for sensory and motor signaling. (R) Forms the major part of the human brain, longitudinally divided into two cerebral hemispheres. (S) Located between the thalamus/hypothalamus and pons, containing corpora quadrigemina dorsally. (T) Contains centres controlling respiration, cardiovascular reflexes, and gastric secretions. Which of the following options represents the correct match?
Correct answer: D — (i)-R, (ii)-Q, (iii)-P, (iv)-S, (v)-T
This question requires matching different brain parts with their specific characteristics, locations, or functions as described in the NCERT text. (i) Cerebrum: Forms the major part of the human brain, longitudinally divided into two cerebral hemispheres. So, (i) matches (R). (ii) Thalamus: It is a major coordinating centre for sensory and motor signaling. So, (ii) matches (Q). (iii) Hypothalamus: It contains a number of centres which control body temperature, urge for eating and drinking. So, (iii) matches (P). (iv) Midbrain: It is located between the thalamus/hypothalamus of the forebrain and pons of the hindbrain. Its dorsal portion consists of corpora quadrigemina. So, (iv) matches (S). (v) Medulla oblongata: It contains centres which control respiration, cardiovascular reflexes and gastric secretions. So, (v) matches (T). Based on these matches, the correct option is D
