The cell membrane is selectively permeable, allowing only certain substances to pass through. Passive transport is a way that small molecules or ions move across the cell membrane without input of energy by the cell. The three main kinds of passive transport are diffusion, osmosis, and facilitated diffusion.
Preemptive analgesia, a developing clinical concept, is starting an analgesic regimen before the onset of painful stimuli in order to avoid making the nervous system more sensitive to pain-inducing stimuli in the future.
- Pre-emptive analgesia is an antinociceptive medication administered prior to an incision or surgery, thus it's crucial to keep in mind when it should be administered.
- This aids in avoiding the development of altered afferent input processing, which would otherwise exacerbate postoperative pain.
- The three intravenous opioids that are most frequently used to treat postoperative pain are morphine, hydromorphone (dilaudid), and fentanyl.
- The drug of choice for opiates is morphine, which is frequently utilized.

Biogeographic isolation means that a population is separated and there are two populations in two different areas. As normal mutations take place, but certain mutations will be seen as advantageous in the different areas. For. Example if an area had taller trees the organism may develop a gene to grow taller. This is then passed down to offspring. This process continues so that more gene differences are created within the species and the frequency of these alleles increased: leading to two different species developing-
