Exploring the Nervous System

What are the two main components of the central nervous system?

• Brain and spinal cord

• Brain and nerves

• Spinal cord and nerves

• Brain and heart

Which part of the nervous system is responsible for voluntary movements?

• Autonomic nervous system

• Central nervous system

• Somatic nervous system

• Sympathetic nervous system

What is the primary function of the peripheral nervous system?

• To process information in the brain

• To connect the central nervous system to limbs and organs

• To control reflex actions

• To regulate emotions

Which of the following is NOT a type of neuron?

• Sensory neuron

• Motor neuron

• Interneuron

• Glial neuron

What is the role of the sympathetic nervous system?

• To calm the body and conserve energy

• To stimulate the body's fight-or-flight response

• To regulate voluntary muscle movements

• To process sensory information

Which part of the neuron receives signals from other neurons?

• Axon

• Dendrites

• Soma

• Synapse

What is the function of the parasympathetic nervous system?

• To increase heart rate and blood pressure

• To prepare the body for physical activity

• To promote rest and digestion

• To transmit sensory information to the brain

What is a synapse?

• A type of neuron

• A gap between two neurons

• A part of the brain

• A type of neurotransmitter

Which of the following is a characteristic of the autonomic nervous system?

• It controls voluntary muscle movements

• It operates independently of conscious control

• It is part of the central nervous system

• It only functions during sleep

What is the main function of motor neurons?

• To transmit signals from the brain to muscles

• To carry sensory information to the brain

• To connect neurons within the brain

• To regulate autonomic functions
