What happens in irreversible cell injury?
Irreversible responses of cell injury refer to changes that lead to a new equilibrium with the environment. Types of irreversible responses include: interruption of membrane integrity; hydrolysis of phospholipids, proteins and nucleic acids; and necrosis, where organelles undergo a sequence of changes.
What are the features of reversible cell injury?
reversible cell injury
- plasma membrane blebbing.
- plasma membrane blunting.
- distortion of microvilli.
- creation of myelin figures.
- loosening of intercellular attachments.
What are the four mechanisms of cellular adaptation?
Overview: The four basic types of cellular adaptation to be discussed in this section are hyperplasia, hypertrophy, atrophy, and metaplasia.
What is the function of the articularis genu muscle?
The articularis genu is a small flat muscle of the anterior knee. During knee extension it acts to tighten the synovial membrane superiorly thereby preventing impingement of the synovial folds between the femur and the patella. Article:
Where is the articularis genu on the patella?
“To find the articularis genu, palpate the quadriceps at its distal attachment on the patella, gently investigate medially, with your index and 3rd finger under vastus medialis, and laterally with thumbs under vastus lateralis. Attempt to pinch or connect your fingers and thumbs together.
How is the articularis genus related to the knee?
The Anatomy of the Articularis Genus Muscle and Its Relation to the Extensor Apparatus of the Knee The association between the articularis genus, vastus medialis, and vastus intermedius may be more complex than previously believed, and this close anatomical connection could have functional implications for knee surgery.
Is the articularis genus an independent muscle?
Conclusions: The articularis genus, vastus medialis, and vastus intermedius have a complex, interacting architecture, suggesting that the articularis genus most likely does not act as an independent muscle.
