Nervous System part I

What are the two main divisions of the nervous system?

• Somatic and autonomic nervous system

• Central and peripheral nervous system

• Sympathetic and parasympathetic nervous system

• Afferent and efferent nervous system

Which division of the Peripheral Nervous System (PNS) controls the skeletal muscles?

• Autonomic

• Sympathetic

• Parasympathetic

• Somatic

What is the function of the Sympathetic division of the Autonomic Nervous System?

• Rest and digest

• Fight or flight

• Control of skeletal muscles

• Control of smooth/cardiac muscle and glands

The Parasympathetic division is associated with which of the following responses?

• Brain and Nerves

What structure is indicated in the image of the spinal column?

• Neurons

• Axons

• Ganglia

• Synapses

What is the function of neurons in the nervous system?

• To support other cells

• To receive and transmit nerve impulses

• To carry oxygen to the brain
