01 Oct The nervous system is made up of:
Question 1. The nervous system is made up of:
Retina and neurons
Ganglia and nerves
Central and peripheral nervous system
Brain and spinal cord
Question 2 Which are the components of the central nervous system?
White and gray matter
Spinal cord and ganglia
Brain and nerves
Motor and sensory neurons
Question 3. The parts of the central nervous system are:
Retina and optical nerve
Brain and spinal cord
Brain stem and nerve cells
Neurons, retina and ganglia
Question 4 What are the parts of the peripheral nervous system?
Spinal cord and ganglia
Axons and synapses
Sensory receptors and motor neurons
Ganglia, neurons and nerves
Question 5 How does the nervous system coordinate actions and responses in our bodies?
Through producing synapses
By transmitting signals between different parts of our bodies
Through electrical impulses
By sending messages along the axons in neurons
Question 6 What are the core functions of the nervous system?
To help human perceive their environment
To coordinate voluntary actions
To control involuntary actions
To control and communicate information throughout the body using sensory input, integration and motor output
Question 7 Which of the following statements is false about glia cells?
They are neuronal cells
They maintain homeostasis
They form myelin
They provide support and protection for neurons in the brain and other parts of the nervous system
Question 8 The following are types of glial cells:
Microglia and dendrites
Oligodendrocyte and cell membrane
Microglia and axon
Neuron and astrocyte
Question 9 Which of the following are not parts of a neuron?
Node, terminal & neuron
Myelin sheath, axle & astrocyte
Node of Ranvier, nucleus & axon hillock
Dendrites, Schwann cell & synapse
Question 1010. How do neurons communicate with other cells?
By releasing neurotransmitters at synapses
Through the fiber called the axon
By releasing chemicals and sending signals
By electrical signals through the myelin sheath
Question 11 What is the function of myelin sheath on the neuron?
To act as a shock absorber
To increase signal speed
To block wrong communication
To control the whole cell
Question 12 Neuroglia support neuronal function by:
binding to receptor molecules
rejuvenating the axon sheath
rejuvenating the neighboring cells
providing nutrition, support and protection
Question 13 What doesn’t the nervous system do?
Initiates actions
Coordinates muscle activity
Monitors body organs
Shuts down data from the receptors
Question 14 Sophistication of the nervous system enables:
Singing in the rain
Language and transmission of culture
Holding hands
Drawing
Question 15. Which of the following is false?
The nervous system is made up of the PNS and CNS
Sensory input, integration and motor output enable nervous system functions
Neural circuits do not inform our perceptions or determine our behavior
Ganglia, nerves and neurons make up the PNS
