Hi, it's rogum 11 in chapter 36 animal endocrine system.
00:05
So the question is that how do hormones, paragrine signaling molecules, neurodramers and pheromones differs? so first we will find a difference between hormones and paragrine signaling molecules.
00:16
So first we will discuss hormones.
00:18
What are hormones? hormones are released from the endocrine glands, then released in blood flow where they find the target cells to action.
01:28
And then we will discuss paragrine signaling molecules.
01:52
It differs from the hormones because paragrin signaling molecules act locally to affect the behavior of neural cells.
02:02
It acts locally to affect the behavior of nervous cells.
02:28
In paragrin signaling, a molecule raised by one cell acts on neighboring cells target.
02:38
Molecule released by one cell, axon, neighboring, target cells.
03:20
Then we will differentiate hormones and neurotransmitters.
03:49
As we know, hormones are released from endocrine glands and then released into bloodstream.
03:55
We define their target cells to action...
