Introduction to the Nervous System

What is the primary function of the nervous system as described in the transcript?

• To digest food

• To store energy

• To circulate blood

• To act as a complex communication network

Which cells are responsible for picking up and sending information in the nervous system?

• Red blood cells

• Neurons

• Muscle cells

• Skin cells

What do sensory neurons or sensory organs do with the information they pick up?

• Store it for later use

• To convert energy

• Send it to the brain and spinal cord

• Destroy it

What happens to the information once it reaches the brain and spinal cord?

• It is integrated or made sense of

• It is ignored

• It is immediately discarded

• It is converted into sound

What are the supporting cells in the nervous system called?

• Erythrocytes

• Glia

• Osteocytes

• Myocytes

What do the supporting cells in the nervous system do?

• They pick up various types of information

• They produce hormones

• They transport oxygen

• They digest food

What is the role of the brain and spinal cord in the nervous system?

• To produce energy

• To store fat

• To integrate information and decide actions

• To filter blood

What happens after the brain and spinal cord decide what to do with the information?

• They ignore it

• They store the information for future use

• They convert it into sound

• They send a signal to muscles, glands, and organs

What type of information does the nervous system pick up every minute?

• Thousands of bits

• Millions of bits

• Billions of bits

• Trillions of bits

What is the main component of the nervous system that acts as its functional subunits?

• Hormones

• Enzymes

• Neurons

• Proteins
