sodium
Question 2
Question
The is a significantly [blank_start]higher[blank_end] concentration of Calcium extracellularly.
Question 3
Question
Na flows inwards, causing [blank_start]depolarisation[blank_end] which is [blank_start]excitatory[blank_end]
Ca flows inwards, causing [blank_start]depolarisation[blank_end] which is [blank_start]excitatory[blank_end]
Cl flows inwards, causing [blank_start]hyperpolarisation[blank_end] which is [blank_start]inhibitory[blank_end]

Question 7
Question
There are two types of receptors upon which neurotransmitters can act.
[blank_start]Ionotropic Receptor[blank_end]: Direct gating, whereby the receptor is an integral part of the channel it controls
[blank_start]Metabotropic Receptor[blank_end]: Indirect gating, whereby the receptor and the channel it controls are distinct from one another.
Answer
-
Ionotropic Receptor
-
Metabotropic Receptor
-
Synapotropic Receptor
Question 8
Question
Label the receptor types shown in the diagram below.
Answer
-

Synapotropic Receptors
-
Metabotropic Receptors
Question 9
Question
The major excitatory neurotransmitter is ...
Answer
-
GABA
-
Glutamate
-
Glycine
-
Dopamine
Question 10
Question
However, Glutamate can sometimes also elicit inhibitory effects via [blank_start]metabotropic[blank_end] glutamate receptors
Question 11
Question
Ionotropic Glutamate Receptors:
NMDA receptors mediate [blank_start]slow[blank_end] excitatory synaptic transmission in the CNS
Non-NMDA receptors mediate [blank_start]fast[blank_end] excitatory synaptic transmission in the CNS
Question 12
Question
The major inhibitory neurotransmitter is ...
Answer
-
Glutamine
-
GABA
-
Glycine
-
Dopamine
Question 13
Question
As GABA is an inhibitory Neurotransmitter, it tends to mediate which of the following ions.
[blank_start]Potassium & Chlorine[blank_end]
Answer
-
Potassium & Chlorine
-
Potassium & Sodium
-
Sodium & Chlorine
-
Sodium & Calcium
Question 14
Question
Ionotropic GABA receptors tend to mediate [blank_start]Chlorine channels[blank_end]
Metabotropic GABA receptors tend to mediate [blank_start]Potassium channels[blank_end]
Answer
-
Chlorine channels
-
Potassium channels
-
Potassium channels
-
Chlorine channels
Question 15
Question
[blank_start]Ionotropic[blank_end] Receptors are faster and act simply as 'on-off' switches for channels
Question 16
Question
[blank_start]Excitatory Post-Synaptic Potential (EPSP[blank_end]): Depolarising change in resting membrane potential caused by actions of neurotransmitters.
[blank_start]Inhibitory Post-Synaptic Potential (IPSP[blank_end]): Hyperpolarising change change in resting potential caused by actions of neurotransmitters.
Question 17
Question
A change in resting membrane potential caused by EPSP or IPSP that is not of sufficient magnitude to cross the threshold for an action potential is called ...
Question 18
Question
Which neurotransmitter are excitatory neurons most likely to release?
[blank_start]Glutamate[blank_end]
Question 19
Question
Neurotransmitters are released in discrete packages called [blank_start]quanta[blank_end]
