The involuntary actions in the body are controlled by:(a) medulla in forebrain (b) medulla in hindbrain(c) medulla in spinal cord (d) medulla in midbrain

Academic Biology NCERT Class 10

(b) medulla in hindbrain.

Involuntary actions such as heartbeat, breathing, blood pressure and peristaltic movement in the body, are controlled by the medulla located in the hindbrain.
