Answer 1

limbic system

Question 2

Which part of a neuron is sometimes myelinated

Answer 2

axon

Question 3

The somatic nervous system

Answer 3

is part of the PNS and participates in sensory and motor interactions with the external environment

Question 4

Gray matter of the spinal cord is largely composed of

Answer 4

cell bodies and unmyelinated interneurons

Question 5

In its resting state, a neuron is said to be

Answer 5

polarised

Question 6

Metabotropic receptors are linked to

Answer 6

signal proteins and G proteins

Question 7

Ions pass through the neural membrane via specialised pores called

Answer 7

ion channels

Question 8

With respect to neurotransmitters, the correct sequence is

Answer 8

synthesis, storage, exocytosis, reuptake

Question 9

A CT scan of the human brain is usually presented as a series of eight or nine

Answer 9

horizontal sections

Question 10

The main difference between the average event-related potential (ERP) and the ‘raw’ electroencephalography (EEG) signal for a single trial is that

Answer 10

random noise in the ongoing EEG is cancelled out by signal averaging

Question 11

Positron emission tomography (PET)

Answer 11

uses different types of radioactive isotopes to image neurotransmitter transport and receptor binding in the brain

Question 12

Disruptive transcranial magnetic stimulation (‘virtual lesion’ TMS) involves

Answer 12

stimulating a cortical region at specific time(s) during performance of a cognitive task and measuring behaviour to determine if and when that cortical region is critically involved

Question 13

Most cell division in the developing neural tube occurs in the

Answer 13

ventricular zone

Immature cells that have the potential to develop into many, but not all, classes of mature cells (e,g blood, skin, hair, neurons) are called

Answer 14

pluripotent

During migration, most neurons are guided to their ultimate location by special progenitor cells known as

Answer 15

radial glia

Question 16

How many ventricles are in the brain

Answer 16

4

Question 17

The large cortical ridges between fissures are called

Answer 17

sulci

Question 18

The large, two-lobed subcortical structure that sits atop the brain stem is the

Answer 18

thalamus

Question 19

The autonomic nervous system (ANS) is part of the

Answer 19

peripheral nervous system (PNS)

Answer 20

antagonist

Question 21

Pump mechanisms in the cell membrane of neurons move (blank) ions out of the neuron to maintain the membrane potential

Answer 21

sodium

Question 22

In humans, EEG electrodes are usually taped to the

Answer 22

scalp

Question 23

Growing axons follow the routes of axons already established by pioneer growth cones. They follow the first axons by a process known as

sensitive, critical
