The Fluid Mosaic Model of the Cell Membrane

1. The Fluid Mosaic Model of the Cell Membrane

In this lesson, we will discuss the components of the cell membrane and why the fluid mosaic model paints the best picture of its structure. We'll learn about the roles of the phospholipid bilayer, cholesterol, proteins and carbohydrates.

Multicellular Organisms, Tissues and Epithelium

2. Multicellular Organisms, Tissues and Epithelium

In this lesson on multicellular organisms, you'll take a look at what it actually means to be multicellular and how cells are organized into tissues, organs, and organ systems. This lesson also covers one of the four main tissue types: epithelial tissue.

Cellular Adaptation: Increases in Number or Size

3. Cellular Adaptation: Increases in Number or Size

This lesson will compare and contrast different types of cell, organ, and tissue growths. More specifically, we'll cover hypertrophy, hyperplasia, and neoplasia.

Conversion or Decreases in Cell Type or Number

4. Conversion or Decreases in Cell Type or Number

This lesson will discuss cellular changes in the body such as metaplasia, dysplasia, atrophy, aplasia, and hypoplasia. We'll talk about their meanings as well as some examples of why they may occur.

Causes of Cell Injury: Oxygen Deficiency

5. Causes of Cell Injury: Oxygen Deficiency

This lesson will discuss how cells may be damaged due to various causes of oxygen deficiency. We'll discuss hypoxia, anoxia, ischemia, anemia, carbon monoxide, and cyanide toxicity.

Types of Physical Injury to Cells

6. Types of Physical Injury to Cells

This lesson will discuss some forms of cellular injury, such as trauma, temperature extremes, and radiation, as well as why cells are damaged in these events and how that may impact your body if the damage is severe enough.

Cellular Injury: Infectious Causes & Their Processes

7. Cellular Injury: Infectious Causes & Their Processes

This lesson will talk about how bacteria, viruses, and parasites may contribute to or directly cause injuries and death to cells, organs, and the entire body. We will discuss exotoxins, endotoxins, and much more.

Other Causes of Cellular Injury

8. Other Causes of Cellular Injury

This lesson will point out some ways that the cells in our body can become injured as a result of an aberrant immune system, dietary problems, and metabolic and genetic diseases.

How a Cell Recognizes an Injury

9. How a Cell Recognizes an Injury

Cells can suffer damage resulting from infection, trauma, or injury. When this happens, cells must decide how to respond for the good of the body. In this lesson, we'll learn how a cell recognizes injury and uses apoptosis, necrosis, and other signals to die or even kill itself.

The Causes and Significance of Cell Swelling

10. The Causes and Significance of Cell Swelling

This lesson will discuss the main manifestation of cellular injury, called cell swelling. We'll delve into exactly why this occurs as well as how ATP and fatty degeneration are involved.

The Causes and Significance of Tissue Swelling

11. The Causes and Significance of Tissue Swelling

This lesson will discuss the different types of swelling and growths that may appear in or on your organs and tissues. We'll cover everything from hematomas and seromas to cancer and splenomegaly.

Irreversible Cellular Injury and Death: Types and Causes

12. Irreversible Cellular Injury and Death: Types and Causes

This lesson will discuss the different causes and types of irreversible cell injury. Notably, we'll focus in on the different types of necrosis that may occur in the body, their causes, and what they may look like.

The Consequences of Intracellular Accumulations

13. The Consequences of Intracellular Accumulations

This lesson will discuss the basic concepts of intracellular, tissue, and organ accumulations, why they may occur and what they may cause. Lipid, glycogen, pigment, iron, and protein accumulation will be covered.

Common Postmortem Changes

14. Common Postmortem Changes

This lesson will discuss four common postmortem changes. Namely, we'll look into algor mortis, rigor mortis, pallor mortis, and livor mortis. We'll talk about what they mean, why they occur, and how they might be used by a crime scene investigator.

Vaccination and Immunotherapy

15. Vaccination and Immunotherapy

This lesson will discuss the basics of how diseases can be prevented or treated using our own immune system's components. We'll talk about vaccination and immunotherapy as well as some specific examples, such as the BCG vaccine, monoclonal antibodies, and more.

Rigor Mortis: Definition, Timeline & Stages

16. Rigor Mortis: Definition, Timeline & Stages

What was the time of death? This is often asked by family members of the deceased after a death investigator completes the initial investigation. One of the most important processes after death is rigor mortis. Learn more about this term, the timeline and its various stages.

Medication Adherence: Definition, Tools, & Statistics

17. Medication Adherence: Definition, Tools, & Statistics
