• Stomach and intestines

• Liver and kidneys

• Heart and lungs

What are the two divisions of the nervous system?

• Sympathetic and parasympathetic

• Somatic and autonomic

• Central and peripheral

• Cranial and spinal

Which division of the peripheral nervous system controls voluntary muscle control?

• Autonomic nervous system

• Sympathetic division

• Sensory division

• Motor division

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

• Somatic nervous system

• Parasympathetic division

• Sympathetic division

• Motor division

What are the two major types of nerve cells?

• Neurons and neuroglia

• Schwann cells and satellite cells

• Axons and dendrites

• Astrocytes and microglia

Which part of the neuron brings impulses towards the cell body?

• Cell body

• Dendrite

• Neurilemma

• Axon

What is the function of the myelin sheath?

• To release neurotransmitters

• To provide insulation and increase the speed of nerve impulses

• To support and anchor neurons

• To protect the neuron from damage

What are the functions of neuroglia?

• Regulate body temperature and blood pressure

• Conduct impulses around the body

• Support and anchor neurons, provide immune response, secrete cerebrospinal fluid

• Control voluntary muscle movements

What is the resting potential of a neuron?

• The release of neurotransmitters at the synapse

• The change in electrical charges that occurs during depolarization

• The state of the neuron when it is actively sending impulses

• The state of the neuron when it is not receiving any impulses

What is the function of the cerebellum?

• To relay sensory impulses to the cerebral cortex

• To regulate body temperature and blood pressure

• To control voluntary muscle movements

• To coordinate movements and aid in muscle memory
