Question: 1 / 400

Which is the largest and most complex nerve tissue in the body?

Spinal cord

Heart

Brain

The brain is the largest and most complex nerve tissue in the body because it controls and coordinates all bodily functions, including movement, speech, thought, and emotions. The spinal cord is also a nerve tissue, but it is smaller and mainly serves as a pathway for nerve signals to and from the brain. The heart is made of cardiac muscle tissue, which is important for pumping blood throughout the body, but it does not have the same level of complexity as the brain. Muscle tissue, while essential for movement, is not a nerve tissue and does not have the same level of complexity or control over bodily functions as the brain. Therefore, the correct answer is C Brain.
