Nervous - general

What are the main components of the central nervous system (CNS)?

• Brain and spinal cord

• Heart and lungs

• Stomach and intestines

• Muscles and bones

Which system is responsible for interpreting internal and external signals in the body?

• Digestive system

• Nervous system

• Respiratory system

• Circulatory system

What is a key function of the peripheral nervous system (PNS)?

• Regulating blood flow

• Separating into different neuronal types

• Producing hormones

• Digesting food

How does the nervous system coordinate with the endocrine system?

• By providing rapid responses to stimuli

• By slowing down and providing long-term responses to stimuli

• By increasing heart rate

• By digesting food

What is the role of sensory neurons?

• Control of voluntary movements

• Pick up signals from internal and external stimuli

• Involuntary responses

• 'Fight or flight' response

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

• Parasympathetic

• Sensory

• Sympathetic

• Motor

What are the main discrete structures of the central nervous system?

• Heart and lungs

• Brain and spinal cord

• Muscles and bones

• Skin and hair

What is the role of the autonomic nervous system?

• Control of voluntary movements

• Involuntary responses

• Pick up signals from stimuli

• Transmit sensory information upwards

What does the parasympathetic nervous system control?

• 'Fight or flight' response

• 'Rest or digest' response

• Voluntary movements

• Sensory signal pickup

What is the primary function of afferent neurons in the nervous system?

• To carry motor impulses from the brain to the spinal cord

• To process and store sensory information

• To initiate voluntary movement

• To regulate heart rate
