Q

I am an insulin independent cell.

A

neuron in the brain.

17
Q

True of false:

Neurons are permeable to Sodium and potassium ?

A

true,

they need transporters

18
Q

In pharmacology, we use the help of a specific arrangement of fat molecules to carry the drug…

A

Liposome

19
Q

How do you call an action potential that jumps between node of ranvier?

A

A saltatory conduction

20
Q

How does an electrical synapse pass the signal?

A

directly from the cytoplasm of one cell to another through the pores of gap junction protein.
Information can flow in both directions through most gap jct, but in some current can flow in only one direction.

21
Q

Where do electrical signal mainly occur?

A

In neurons of the CNS

They are also found in glial cells, in cardiac and smooth muscle, and in nonexcitable cells that use electrical signals such as the pancreatic beta cell.

22
Q

Chemical synapses

How does in carry info?

A

With the help of neurocrine molecules

Synapses

23
Q

Neuro.. and neuro…

act as paracrine signals and autocrine signals.

A

Neurotransmitters and neuromodulators

P.254

24
Q

A neuron may terminate on one of three structure

A

muscle
gland
neuron

slide 70

25
Q

I am a tiny bulge at the end of a terminal branch of a presynaptic neuron>s axon that contains vesicles housing neurotransmitters.

A

synaptic knob

26
Q

Neurocrine receptors can be divided into 2 categories

A

Receptor-channels

GPCR

27
Q

FAST OR SLOW
GPCR
Receptor-channels

A

GPCR : slow

Receptor-channels : fast

28
Q

Can GPCR regulate the openning of a channel?

A

yes

29
Q

All neurotransmitters bind to

A

Specific receptor types

except NO

30
Q

3 arrangement of synapses

+draw them

A

Axodendritic
Axosomatic
Axoaxonic

31
Q

What happens when there is a depolarization of the presynaptic neuron ? (one step)

A

It opens the volatage-gated Ca2+ channels.

32
Q

2 characteristics of Na-K pump.

A

Active (needs ATP)

Antiport - sodium goes out of cell, K pumped in the cell

33
Q

PNS secretes 3 major neurocrine molecules

A

Neurotransmitters
acetylcholine
norepinephrine

34
Q

CNS secretes 3 chemicals signals

A

polypeptides:
hypothalamic releasing hormones
oxytocin
vasopressine

35
Q

Acetylcholine is synthesized from 2 mokecules

A

Choline

acetyl coenzyme A (acetyl CoA)

36
Q

What is recycled (neurotransmitter Acetlycholine)

A

Choline

37
Q

The action potential.

What happens after the rapid Na+ entry depolarizes the cell?

A

Na+ channels close and slower K+ channels open
