Flaccid paralysis is a neurological illness characterised by muscle weakness or paralysis and low muscle tone for no apparent reason (e.g., trauma). This aberrant condition can be caused by disease or trauma to the nerves that control the muscles involved. If the somatic nerves supplying a skeletal muscle are cut, the muscle will become flaccid paralysed. Muscles become limp and unable to contract when they reach this stage. If the illness affects the breathing muscles, it might lead to asphyxia. It can also happen during the spinal shock stage when the spinal cord is completely transectioned, as in gunshot wounds.A hypertonic solution is what this is called. Osmosis causes water to flow out of the cells and into the surrounding fluid. The protoplasm, or all of the material on the inside of the cell, shrinks away from the cell wall as a result of this.
Flaccid and Plasmolysed Cells
Turgid refers to something that has been enlarged, usually by fluids, such as a turgid water balloon that you can’t stop yourself from dropping on your friend’s head. The word turgid is derived from the Latin word turgidus, which means “swollen, inflated.” Turgid can be used metaphorically to indicate things that are exaggerated.
That may bring to mind the egos of some people! If a famous singer wants to show off his tremendous vocal range as well as his love of yodelling in a single song, the result could be turgid, with notes and styles bloated to the point of bursting. When plant cells are placed in a hypertonic solution, they get plasmolysed, which means they lose water from their cytoplasm. . As a result, the cytoplasm’s water potential is increased.
Osmosis is the process of water passing across a semipermeable membrane, such as the cell membrane. Exosmosis is when osmosis occurs from the inside to the exterior. Furthermore, as water is lost, the turgor pressure of the cytoplasm decreases.
Similarities Between Flaccid and Plasmolysed
Plant cells can be flaccid or plasmolyzed when the protoplasm exerts no turgor pressure on the cell wall. As a result, neither situation allows the protoplasm to solidify up.
The two factors that cause each disease are endosmosis and exosmosis. Plasmolysis occurs when a plant cell is placed in a hypertonic solution and loses water and thus turgor pressure: pressure drops to the point where the cell’s protoplasm peels away from the cell wall, leaving gaps between the cell wall and the membrane and causing the plant cell to shrink and crumple. Continuing to lower the pressure causes cytorrhysis, or the total collapse of the cell wall.
Plants having this state of cells wilt.. Exosmosis occurs when the solution surrounding the cell is hypertonic, and the space between the cell wall and the cytoplasm is filled with water.Hypertonic refers to a solution that contains more solutes than another. A hypertonic extracellular fluid, for example, contains more solutes than the contents of the plant cell.
Causes of Flaccid
- A lower motor neuron injury may be linked to flaccid paralysis. In contrast, an upper motor neuron lesion frequently manifests as spasticity, though it can sometimes manifest as flaccid paralysis early on
- Poliomyelitis (polio), transverse myelitis, Guillain–Barré syndrome, enteroviral encephalopathy, traumatic neuritis, Reye’s disease, and others are among the conditions listed by AFP
- To increase the number of cases of poliomyelitis, an AFP surveillance programme is being implemented. This entails taking two stool samples within fourteen days of paralysis start, identifying the virus, controlling the epidemic, and boosting immunisation in the affected area
- Oral polio immunizations may cause flaccid paralysis in some cases, according to historical data from the 1950s, present CDC reports, and a new review of trends in India
Difference Between Flaccid and Plasmolysed
| Flaccid | Plasmolysed |
| Flaccid refers to a situation in which plant cells are suspended in an isotonic solution | Plasmolysed refers to a condition in which plant cells are suspended in a hypertonic solution. |
| In the flaccid state, the protoplast exerts no pressure on the cell wall | When plant cells are plasmolyzed, the protoplast shrinks and exerts no pressure on the cell wall. |
| When cells are placed in an isotonic solution, they become flaccid | But when they are placed in a hypertonic solution, they become plasmolyzed. |
| Both endosmosis and exosmosis occur at the same rate in flaccid cells. | But exosmosis occurs in the evacuation of water from the protoplasm in plasmolyzed cells. |
Conclusion
The fundamental distinction between flaccid and plasmolysed is that flaccid refers to a situation in which plant cells are suspended in an isotonic solution, whereas plasmolysed refers to a condition in which plant cells are suspended in a hypertonic solution. The protoplasm, or all of the material on the inside of the cell, shrinks away from the cell wall as a result of this. Osmosis is the process of water passing across a semipermeable membrane, such as the cell membrane. Plant cells can be flaccid or plasmolyzed when the protoplasm exerts no turgor pressure on the cell wall. Plasmolysis occurs when a plant cell is placed in a hypertonic solution and loses water and thus turgor pressure: pressure drops to the point where the cell’s protoplasm peels away from the cell wall, leaving gaps between the cell wall and the membrane and causing the plant cell to shrink and crumple.
