Flashcards

Phospholipid

A type of lipid with a hydrophilic head and hydrophobic tail, forming the structural basis of cell membranes.

Rough Endoplasmic Reticulum (RER)

The rough endoplasmic reticulum is involved in protein synthesis and modification; it is studded with ribosomes.

Smooth Endoplasmic Reticulum (SER)

The smooth endoplasmic reticulum is involved in lipid metabolism, detoxification, and calcium storage; it lacks ribosomes.

Mitochondria

The powerhouse of the cell, generating energy through cellular respiration.

Study Notes

Cell Structure Diagrams

  • Various diagrams depict different cell structures and components. These include cell membranes, various types of cells, and cell organelles.

Microscopic Images

  • Images of tissues and cells are displayed, showing variations in cell types, sizes, and structures. The images include stained samples, demonstrating the way certain cellular components are highlighted under a microscope.

Tissue Types

  • Different tissue types are shown, including liver, kidney, muscle, and blood.

Cell Organelles

  • Images depict cell organelles like mitochondria and the Golgi apparatus. Specific cellular components are labeled.

Cellular Processes

  • Diagrams illustrate cellular processes, showing transport vesicles and the Golgi apparatus's role in secretion.

Cytoskeleton Components

  • The cytoskeleton, a complex framework within cells, is visualized with depictions of its components.

Blood Cell Images

  • Blood cell types and their varied characteristics are exemplified.

Histology Study

  • The study involves the examination and identification of different tissues, cells, and structures through microscopic visualization. The presentation encompasses variations in tissue structures, providing examples of how tissues (and cells within) react to different conditions.

Types of Epithelial Cells

  • The images provide visual examples of cuboidal, columnar, and transitional epithelial cells. Variations including the presence of cilia are shown.

Cell Nuclei

  • Images show different shapes of cell nuclei, as seen through microscopic techniques (like different staining techniques). This includes spherical, bilobed, and multi-lobed types.

Additional details

  • Various labels and annotations are shown, clarifying the components present in each image.
  • Several images show tissue structures.
  • Different staining methods and labels are used on the images to distinguish cellular features.
