Match List I with List II:

List I	List II
A. Pons	I. Provides additional space for neurons, regulates posture and balance
B. Hypothalamus	II. Controls respiration and gastric secretions
C. Medulla	III. Connects different regions of the brain
D. Cerebellum	IV. Neurosecretory cells

Choose the correct answer from the options given below:

Solution & Explanation

Answer: (a) A-III, B-IV, C-II, D-I. Solution: Pons consists of fibre tracts that interconnect different regions of the brain; the hypothalamus contains groups of neurosecretory cells secreting hypothalamic hormones; the medulla contains centres controlling respiration, cardiovascular reflexes and gastric secretions; the cerebellum integrates information from the semicircular canals of the ear (balance/posture). These give the matching A-III, B-IV, C-II, D-I. NCERT Reference: Ch 18, p.236, lines 38-42 — "Pons consists of fibre tracts that interconnect different regions of the brain"
