Exploring the Nervous System

What is the primary function of the Peripheral Nervous System (PNS)?

• To process information and coordinate responses

• To connect the central nervous system to limbs and organs

• To produce hormones

• To regulate blood pressure

Which part of the nervous system is responsible for transmitting sensory information to the central nervous system?

• Efferent system

• Afferent system

• Autonomic system

• Somatic system

What are Nodes of Ranvier?

• Gaps in the myelin sheath along a nerve fiber

• Types of neurotransmitters

• Parts of the brain responsible for memory

• Cells that produce myelin

What is the primary component of the myelin sheath?

• Proteins

• Lipids

• Carbohydrates

• Nucleic acids

Which neurotransmitter is primarily associated with the 'fight or flight' response?
