The odorant molecules arrive either directly by diffusion into the mucus, or are supported by transport proteins (odor binding protein or OBP) that allow the hydrophobic molecules - majority - to penetrate the mucus covering the epithelium, and thus to reach the membrane receptors present on the eyelashes of the olfactory neurons. These transport proteins are thought to concentrate odorant molecules on membrane receptors. As ligands, the odorant molecules bind to membrane receptors on the eyelashes, triggering a transduction pathway for a stimulus involving G.olf protein (first messenger), adenylate cyclase, and cAMP ( second messenger). The second messenger causes the opening of ion channels Ca2 + / Na + present on the plasma membrane of the olfactory receptor, these two ions then enter the cell. Ca2 + causes the opening of a Cl- channel, the output of this ion causes depolarization of the membrane so that the olfactory receptor produces action potentials. These impulses will go directly to the olfactory bulb, in the prefrontal region of the brain, where this information (and that of taste) is processed by the body.

An employee riding his bicycle to work hits a pothole as he enters the parking lot loses control and swerves into the path of a
Paha777 [63]

Answer:

First of all you have to activate the emergency system, which some call SEM. In this way we will call the ambulance to quickly go to the accident area.

Then you have to try to calm the person, take their vital signs, do not go into shock, and in the event that there is a lot of bleeding, perform a tourniquet to avoid bleeding.

As a next step, it is necessary to ensure that the person is immobilized and that the person does not try to stand up or move further to avoid worsening the fracture, since in this case, when the bone is seen, it is an exposed fracture.

Try to keep the injured area as clean as possible and remove dirty clothes or peripheral soil from the area of the injury, as this could lead to future osteomyelitis during the formation of the bone cay once the patient has been treated.

Explanation:

The exposed fractures can be more or less favorable according to whether the muscular action pulls the fractured line separating the ends or even less unfavorable, as well as to promoting the union of the fractured ends.

On the other hand, the exposed fracture, together with the comminuted ones, are the ones with the worst prognosis and the ones that are the most complicated to treat.

Exposure of bone to the external environment may predispose to a high risk of infections that could trigger osteomyelitis, which is a severe infection in bone tissue.
