Week 2 Flashcards
(12 cards)
1
Q
Juxtacrine (direct) communication
A
- contact-dependent signalling
- cells in physical contact with each other through signalling membrane
2
Q
Indirect communication
A
- No direct communication between communicating cells
- requires specific messenger molecules
3
Q
Types of Indirect communication
A
- endocrine
- neurocrine
- paracrine
- autocrine
- neurotransmission
4
Q
Endocrine communication
A
Body sends messages using hormones
5
Q
Neurocrine communication
A
hormones released by neurons into bloodstream
6
Q
Paracrine communication
A
Messenger molecule remains in interstitial fluid and acts on a different cell
7
Q
Autocrine communication
A
cell signals to itself
8
Q
Neurotransmission
A
secretion of neurotransmitter by neuron to act on target cells
9
Q
Neurosecretion
A
- Secretes neurohormones
- Transport through blood stream
- Acts relatively slowly
10
Q
Neurotransmission
A
- Secretes neurotransmitters
- Transport between neurons (synapses)
- Acts very quickly
11
Q
Water soluble hormones
A
- Exits glands through exocytosis
- Clings to protein to allow it to travel through blood vessel into effect cell
12
Q
lipid soluble hormone
A
-
