4 A-II, B-I, C-III, D-IV  

Ans.

(2)

The hindbrain comprises pons, cerebellum and medulla. Pons consists of fibre tracts that interconnect different regions of the brain. Cerebellum has very convoluted surface in order to provide the additional space for more neurons, regulates posture and balance. The medulla contains centres which control respiration, cardiovascular reflexes and gastric secretions. Hypothalamus contains several groups of neurosecretory cells, which secrete hormones called hypothalamic hormones.
