Understanding the Nervous System

What is the primary function of the nervous system?

• To produce hormones

• To process and communicate information

• To digest food

• To circulate blood

Which part of the nervous system processes and integrates information?

• Autonomic Nervous System

• Somatic Nervous System

• Central Nervous System

• Peripheral Nervous System

What does the somatic nervous system control?

• Blood circulation

• Involuntary actions

• Voluntary movements and sensory perception

• Hormone production

Which system is responsible for the 'fight or flight' response?

• Parasympathetic Nervous System

• Sympathetic Nervous System

• Somatic Nervous System

• Enteric Nervous System

What is the role of the parasympathetic nervous system?

• To increase heart rate and breathing

• To control voluntary movements

• To calm the body and return it to balance

• To sense the external world

Which nervous system is thought to work independently of the CNS?

• Peripheral Nervous System

• Enteric Nervous System

• Autonomic Nervous System

• Somatic Nervous System

What are the two main types of cells in the nervous system?

• Muscle and Bone Cells

• Epithelial and Connective Cells

• Red and White Blood Cells

• Neurons and Glia

What is the function of oligodendrocytes?

• To transmit signals over long distances

• To act as immune bodyguards in the CNS

• To provide insulation to neurons in the CNS

• To sense the external world

Which cells provide insulation to neurons in the PNS?

• Astrocytes

• Oligodendrocytes

• Schwann Cells

• Microglia

What is the role of afferent neurons?

• To act as immune bodyguards

• To transmit signals away from the CNS

• To receive information and pass it towards the CNS

• To provide insulation to neurons
