UNIT 2 Topic 2: Neural pathways

What is the basic cellular unit of the nervous system?

• Neuron

• Axon

• Soma

• Schwann cell

Which nerve cells transmit impulses away from the central nervous system to trigger responses?

• Interneurons

• Motor neurons

• Sensory neurons

• Al of the above

The tiny space between the axon terminal and its target is the:

• myelin sheath.

• synapse.

• presynaptic neuron.

• neurotransmitter.

Which process converts one type of signal to another?

• Deolarisation

• Signal induction

• Signal transduction

• Restoration of resting potential

A neurotransmitter is:

• a type of cell used by the nervous system.

• a type of membrane found exclusively in the nervous system.

• a type of process that occurs in the nervous system.

• a type of hormone used by the nervous system.

Each individual nerve fibre is made of which components?

• Axon and Node of Ranvier

• Myelin sheath and Nissl granules

• Axon and Myelin sheath

• Nodes of Ranvier and Nissl granules.

The three types of neurons (when based on structure) are:

• Monopolar, Bipolar and Multipolar.

• Astropolar, Micropolar and Monopolar.

• Bipolar, Astropolar and Lippipolar.
