Question 1

Which 5 autonomic receptors transmit signal through G(s)?

Answer 1

G(s) = β1, β2, H2, V2, D1 (need to memorize, but if you memorize G(q), this will be easy)

Question 2

Which 5 autonomic receptors transmit signal through G(q)?

Answer 2

G(q) = α1, H1, V1, M1, M3 (all the 1’s except β1 and D1)

• “HAVe 1 M&M” is a popular mnemonic used to remember G(q)

Question 3

Which 3 autonomic receptors transmit signal through G(i)?

Answer 3

G(i) = α2*, M2, D2

• Remember α2 is inhibitory → G(i) (rarely will M2 or D2 be tested)
• You can remember these inhibitory receptors as “MAD 2s inhibit”

Question 4

Which types of G protein coupled receptor transmits signals from D1 receptors?

Answer 4

Alternatively, use the mnemonic: “QISS and QIQ till you’re SIQ of SQS”
α1 – Q
α2 – I
β1 – S
β2 – S

M1 – Q
M2 – I
M3 – Q

D1 – S
D2 – I
H1 – Q

H2 – S
V1 – Q
V2 – S

Question 5

What are some (try for eight) functions of the hypothalamus?

Answer 5

The functions of the hypothalmus can be remembered with the mnemonic “TAN HATSS”:

• Thirst (and water balance)
• Adenohypophysis control (via release factors)
• Neurohypophysis control (via direct axon transport)
• Hunger and satiety
• Autonomic regulation
• Temperature regulation
• Sexual desires and emotions
• Sircadian (circadian) rhythm control via suprachiasmatic nucleus

Question 6

What are the sympathetic G-protein-linked receptors?

Answer 6

QISS

α1 - Q

α2 - I

β1 - S

β2 - S

Question 7

What are the parasympathetic G-protein-linked receptors?

Answer 7

QIQ

M1 - Q

M2- I

M3 - Q
