Study Notes

Abdominal Hernia

  • An abdominal hernia occurs when weakened muscles allow abdominal structures to protrude.
  • The serous membrane involved in certain abdominal hernias is the peritoneum.

Knee Joint Replacement

  • The smaller body cavity accessed during a total knee joint replacement is the synovial cavity.

Plasma Cells and Antibodies

  • Plasma cells are crucial for the immune response as they secrete antibodies.
  • These antibodies, being proteins, require an abundance of rough endoplasmic reticulum in plasma cells.

Cell Destruction and Organelles

  • Lysosomes are the organelles responsible for total cell destruction.

Antifungal Medications and Cell Cycle

  • Antifungal medications that inhibit DNA synthesis target cells during the S phase of the cell cycle.

Medical Prefixes and Their Meanings

  • Endo: Means inside, taking, or within.
  • Glyco: Refers to sugar.
  • Nucle: Relates to nucleus or nuclear.
  • Auto: Indicates self or self-acting.
  • Anti: Signifies against or opposite.
  • Cyto: Pertains to cell.

Mitosis Phases

  • Anaphase: The shortest phase of mitosis where chromosomes are pulled toward the cell poles.
  • Prophase: During this phase, the mitotic spindle forms and the nuclear envelope fragments.
  • Centriole: An organelle critical for directing the formation of the mitotic spindle during cell division.
