Difficulty: EasyNervous Coordination and Sense Organs

Match each region of the mammalian brain in Column A with its primary physiological function in Column B.

  • CerebrumControls voluntary actions, reasoning, and conscious thought
  • CerebellumCoordinates voluntary muscle movement and maintains bodily posture and balance
  • Medulla oblongataRegulates autonomic involuntary activities such as heartbeat and respiration rate
  • HypothalamusServes as the main control center for body temperature regulation and osmotic balance

Answer

Cerebrum matches with controlling voluntary actions and conscious thought; Cerebellum matches with coordinating muscle movements and posture; Medulla oblongata matches with regulating autonomic involuntary processes like breathing and heartbeat; Hypothalamus matches with regulating body temperature and homeostatic balance.
Each brain region is matched to its physiological function: cerebrum governs voluntary actions and intelligence; cerebellum manages muscle posture and balance; medulla oblongata controls vital autonomic reflexes such as respiration and heartbeat; hypothalamus regulates homeostatic functions like thermoregulation.

Step-by-Step Solution

1
Identify the function of the cerebrum
It governs conscious sensory interpretation, reasoning, intelligence, and voluntary movement.
The cerebral cortex is the center for higher cognitive and voluntary motor functions.
2
Identify the function of the cerebellum
It integrates sensory inputs from muscles and joints to maintain balance and smooth motor coordination.
Precise muscle coordination and posture maintenance occur in the cerebellum.
3
Identify the function of the medulla oblongata
It controls life-sustaining involuntary actions including heart rate, vasomotion, and breathing rate.
Autonomic reflex centers for vital organ systems are located in the brainstem/medulla.
4
Identify the function of the hypothalamus
It acts as the primary integrator for autonomic homeostasis, thermoregulation, and osmoregulation.
Internal physiological equilibrium is monitored and adjusted by the hypothalamus.
