Basic Concepts of Nervous System

What are the basic units of the nervous system?

• Neurons

• Glial cells

• Meninges

• Cerebral spinal fluid

What is the function of glial cells?

• Provide nutrients and support

• Transmit electrical impulses

• Process information

• Store genetic material

What is the role of neurotransmitters?

• Carry messages between neurons

• Protect the brain

• Support neuron structure

• Transmit pain signals

What happens when the action potential reaches the end of the axon?

• Releases neurotransmitters

• Generates a new action potential

• Stops the signal

• Inhibits the neuron

What is the blood-brain barrier?

• Protects the brain from harmful substances

• Allows all substances to pass

• Is a type of neuron

• Is a neurotransmitter

Why is a constant blood and oxygen supply to the brain critical?

• Brain cannot produce ATP without O2

• Brain stores glucose

• Brain can survive without oxygen

• Brain uses only fats for energy

What is the function of cerebrospinal fluid?

• Shock absorption

• Nutrient storage

• Electrical signaling

• Neurotransmitter transport

What is Myasthenia Gravis?

• An autoimmune condition causing muscle weakness

• A type of neurotransmitter

• A brain injury

• A type of neuron

What is the role of acetylcholine?

• Excitatory neurotransmitter

• Inhibitory neurotransmitter

• Structural protein

• Electrical signal

What is the primary function of the central nervous system?

• Process information

• Transmit signals

• Support neurons

• Protect the brain
