Fisiología Veterinaria S13 - ( parte 3 -final)

Let's talk about two phases. The phase of filling, where you need to fill the vagina, and you are going to be in charge of the nervous system, which through the gastric nerve will release the neurotransmitter, which would be the adrenaline. That adrenaline will lead to the detrusor muscle and to the isoculatory muscle. When it reaches the detrusor muscle, it will have relaxation.

Why? Because it will join to the beta 2 receptors. Beta 2 receptors are coupled to GS proteins, which should be excitatory, but the response generates anemia. So here it relaxes. Relaxes in order for the urine to be stored, so the bladder can increase in size.

Now, it also comes the adreneline of the lateral muscularis, and in this case it is necessary to contract it to prevent the escape of the anus, which in this case unites the receptors to the spine, so that it can be connected. And in turn, through the somatic nervous system, through the pudendal nerve, it will release its transmissor nerve, which would be what? If it is somatic, it is the anus.

If it's a matic, it releases the glycoline. If it's a matic, it releases the glycoline.

It means that the interurethral grandophilus is a skeletal muscle. The receptor is myocardial. Therefore, it is possible to fill the bladder well. Now, once the bladder is filled, which has generated a distension, there are some mecanoreceptors at the level of the walls.

Therefore, they will send the information through the adjacent pathways to the sacral centers, the continuous center, and they will take the response through the parasympathetic pathway, the parasympathetic pathway with the base of the empty. In this case, the pelvic nerves will release the neurotransmitter acetylcholine.

that leads to the muscle of the usurper so that it can contract, therefore here we are going to see that it stimulates the mucocaninic receptors. There are some books where you will find that they say M3 and M1, but I think most authors agree that they are the M3, so that it can contract, and when it contracts it will start emptying the vein. Now,

What happens with the somatic? In the case of the somatic, we no longer need it to be contracted. If the conditions are adequate, that the dog has reached its little tree and that the cat has reached its cataract, then what we are going to see here is that there is an inhibition of the pudendal nerve. Without the pudendal nerve, there is no freeing of the clitoris.

Therefore, the retinal nerve relaxes and finally, the urethra comes out. Is it clear, guys? Or are there any doubts, any questions? The signals that come from the cortex that will begin to release to be able to inhale it, there we will have the respiratory neurotransmitters. Vagina, glycine, right? Provenient.

So there is no more release of the glycolin, therefore the nicotinic receptors are no longer activated, the intraurethral rhabotin is relaxed. Now, you may be wondering what happens with the urethral muscle that we see present above, that is, contrary. What happens is that since the sympathetic is inhibited here, the urethral muscle only responds to the sympathetic. So, since it is inhibited, it is relaxed directly. Very well?

So don't let them get accumulated for the last time. Why? Because there are two endocrine classes that are two very small classes. In fact, the next class is a very heavy class. Both for you to listen to them and for me to tell you because there is so much information. We are going to talk about receptors, about various hormones, and you have to remember them for the exam. Okay? Very good. So if there are no questions, I'll leave them free.
