I WONDER - What Organs Are Part Of The Nervous System? Me Pregunto - Qué Órganos Son Parte Del Sistema Nervioso?

The video explains the components of the nervous system, including the brain, spinal cord, sensory organs, and nerves. It describes how nerves transmit signals to the brain via the spinal cord, often faster than conscious thought. This rapid communication allows for reflex actions, such as withdrawing a hand from a hot surface before feeling pain, as the nerves quickly alert the brain to act.

Which of the following is NOT a component of the nervous system?

• Brain

• Sensory organs

• Heart

• Spinal cord

How do nerves communicate with the brain?

• By sending signals through the muscles

• By sending signals through the spinal cord

• By sending signals through the skin

• By sending signals through the bloodstream

What is a characteristic of nerve signal transmission?

• It is slower than our thought process

• It is faster than our thought process

• It is as fast as our thought process

• It does not involve the spinal cord

Why might your body react before you consciously feel pain?

• Because the nerves quickly alert the brain to act

• Because the brain ignores the signals

• Because the nerves are slow to send signals

• Because the brain is slow to process signals

What is an example of a reflex action?

• Reading a book

• Thinking about a math problem

• Removing your hand from a hot surface

• Walking in a straight line
