CN - Chapter 6 - Neurotransmitter Systems

Question 1

cholinergic

Answer 1

Describing neurons or synapses that produce and release acetylcholine (ACh).

Question 2

noradrenergic

Answer 2

Describing neurons or synapses that produce and release norepinephrine (NE).

Question 3

glutamatergic

Answer 3

Describing neurons or synapses that produce and release glutamate (Glu).

Question 4

GABAergic

Answer 4

Describing neurons or synapses that produce and release gamma-aminobutyric acid (GABA).

Question 5

peptidergic

Answer 5

Describing neurons or synapses that produce and release peptide neurotransmitters.

Question 6

immunocytochemistry

Answer 6

An anatomical method that uses antibodies to study the location of molecules within cells.

Question 7

<i>in situ</i> hybridization

Answer 7

A method for localizing strands of messenger RNA (mRNA) within cells.

Question 8

autoradiography

Answer 8

A method for visualizing sites of radioactive emissions in tissue sections.

Question 9

microionophoresis

Answer 9

A method of applying drugs and neurotransmitters in very small quantities to cells.

Question 10

receptor subtype

Answer 10

One of several receptors to which a neurotransmitter binds.

Question 11

nicotinic ACh receptor

Answer 11

A class of acetylcholine-gated ion channels found in various locations, notably at the neuromuscular junction.

Question 12

muscarinic ACh receptor

Answer 12

A subtype of acetylcholine receptor that is G-protein-coupled.

Question 13

AMPA receptor

Answer 13

A subtype of glutamate receptor; a glutamate-gated ion channel that is permeable to Na⁺ and K⁺.

Question 14

NMDA receptor

Answer 14

A subtype of glutamate receptor; a glutamate-gated ion channel that is permeable to Na⁺, K⁺, and Ca²⁺. Inward ionic current through the <i>N</i>-methyl--asparate receptor is voltage dependent because of a magnesium block at negative membrane potentials.
