Nervous System Overview and cells

What is the primary function of the nervous system?

• Controlling voluntary movements

• Processing information and communication

• Regulating involuntary actions

• Producing hormones

How does the nervous system relate to the brain?

• The brain is the only part of the nervous system

• The nervous system is a part of the brain

• The nervous system is much more extensive than just the brain

• The brain controls the nervous system entirely

What is the main role of the nervous system in the body?

• Transporting nutrients

• Facilitating communication between body parts

• Pumping blood

• Filtering waste products

What three essential actions does a living organism perform with the help of its nervous system to survive?

• Eating, sleeping, and growing

• Sensing, interpreting, and responding

• Breathing, circulating, and digesting

• Moving, speaking, and thinking

Which components make up the Central Nervous System (CNS)?

• Nerves and ganglia

• Brain and spinal cord

• Sensory and motor neurons

• Muscles and organs

What is the function of the afferent (sensory) portion of the Peripheral Nervous System (PNS)?

• Controlling voluntary movements

• Sending signals from the CNS to muscles

• Sensing the external world

• Regulating involuntary actions

Which part of the nervous system is responsible for controlling voluntary movements like sitting up and walking?

• Autonomic Nervous System

• Central Nervous System

• Somatic Nervous System

• Enteric Nervous System

What type of actions does the Autonomic Nervous System (ANS) regulate?

• Voluntary actions

• Conscious thoughts

• Involuntary actions

• Reflexes only

Which part of the nervous system is responsible for the "fight or flight" response, increasing heart rate and breathing?

• Parasympathetic Nervous System

• Somatic Nervous System

• Central Nervous System

• Sympathetic Nervous System

What is the primary function of the parasympathetic nervous system?

• Preparing the body for stress

• Controlling voluntary muscle movements

• Calming the body and promoting digestion

• Sensing external stimuli
