 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
