Total questions: 20
Worksheet time: 15mins
What is the main function of the nervous system?
To produce hormones
To send and receive electrical impulses throughout the body
To transport oxygen in the blood
To produce energy for cells
The two major divisions of the nervous system are the:
Central and Somatic Nervous Systems
Peripheral and Autonomic Nervous Systems
Central and Peripheral Nervous Systems
Sensory and Motor Nervous Systems
What structures make up the central nervous system (CNS)?
Brain and spinal cord
Nerves and spinal cord
Sensory receptors and nerves
Heart and lungs
The peripheral nervous system (PNS) consists of:
The brain and spinal cord
Spinal nerves, cranial nerves, and sensory receptors
The cerebrum and cerebellum
The autonomic nervous system only
What type of nerves carry sensory information from the body to the CNS?
Efferent nerves
Afferent nerves
Motor neurons
Interneurons
The autonomic nervous system controls:
Skeletal muscle movements
Involuntary body functions
Voluntary reflexes
Memory and emotions
Which subdivision of the nervous system is responsible for voluntary movement?
Autonomic Nervous System
Sympathetic Nervous System
Parasympathetic Nervous System
Somatic Nervous System
Which type of neuroglial cells provide insulation to neurons in the CNS?
Schwann cells
Astrocytes
Oligodendrocytes
Microglia
The fatty insulation surrounding some axons, which speeds up nerve impulse transmission, is called:
Synapse
Myelin sheath
Neurotransmitter
Reflex arc
Which of the following correctly matches the function of interneurons?
Transmit impulses from sensory receptors to the CNS
Form connections between afferent and efferent neurons
Carry impulses from the CNS to muscles and glands
Protect neurons by absorbing bacteria and dead cells
The part of a neuron that receives stimuli and transmits signals to the cell body is called:
Axon
Dendrite
Synapse
Myelin
What is the function of neurotransmitters?
They generate electrical impulses
They provide structural support to neurons
They act as chemical messengers between neurons
They produce myelin
What happens at a synapse?
Electrical impulses are generated
Neurotransmitters are released to carry signals between neurons
Myelin is produced
The neuron dies
Which nervous system subdivision is responsible for the “fight or flight” response?
Somatic Nervous System
Parasympathetic Nervous System
Sympathetic Nervous System
Sensory Nervous System
Which type of glial cells dispose of dead cells and bacteria in the CNS?
Astrocytes
Oligodendrocytes
Microglia
Schwann cells
Select the Nodes of Ranvier
Select the axon
Select the dendrites
Label the neuroglia:
Label the PNS glial cell
