AnaPhys1ACE The Nervous System Final Assessment 2022

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
