[31] Role of the Nervous System in Thermogenesis

Question 1

What is the role of the nervous system in thermogenesis?

Answer 1

The nervous system plays a key role in thermogenesis by regulating body temperature and initiating responses to cold and heat.

Question 2

What part of the nervous system is primarily responsible for thermogenesis?

Answer 2

The hypothalamus in the brain is primarily responsible for regulating body temperature and hence thermogenesis.

Question 3

How does the nervous system respond to cold temperatures?

Answer 3

In response to cold temperatures, the nervous system triggers shivering and non-shivering thermogenesis to generate heat and maintain body temperature.

Question 4

How does the nervous system respond to warm temperatures?

Answer 4

In response to warm temperatures, the nervous system triggers mechanisms like sweating and vasodilation to cool the body.

Question 5

What is the role of sympathetic nervous system in thermogenesis?

Answer 5

The sympathetic nervous system activates brown adipose tissue to increase heat production in a process known as non-shivering thermogenesis.
