Question

Which part of the brain regulates body temperature?

Options
  • A

    Cerebellum

  • B

    Cerebrum

  • C

    Hypothalamus

  • D

    Medulla

Explanation

Much like a thermostat regulates the temperature inside your home, the hypothalamus regulates your body temperature, responding to internal and external stimuli and making adjustments to keep the body within one or two degrees of 98.6 degrees.

The cerebellum is primarily responsible for coordinating voluntary movements and balance. It does not regulate body temperature.

The cerebrum is the largest part of the brain, involved in higher brain functions like thought and action. It is not directly responsible for regulating body temperature.

The hypothalamus plays a crucial role in maintaining homeostasis, including regulating body temperature, hunger, thirst, and other autonomic functions.

The medulla controls autonomic functions such as heart rate and breathing, but it does not regulate body temperature.
