Tissues are classified into four basic types: epithelium, connective tissue (includes cartilage, bone and blood), muscle, and nervous tissue. Organs are assembled from the four basic types of tissues and have cells with specialized functions. These slides contain tissue sections that are easily confused with each other.

Cells that have been fixed and stained can be studied in a conventional light microscope, while antibodies coupled to fluorescent dyes can be used to locate specific molecules in cells in a fluorescence microscope. Living cells can be seen with phase-contrast, differential-interference-contrast, dark-field, or bright-field microscopes.

Histology is the study of cells, tissues and organs as seen through the micro-scope. Although this atlas is a guide to biological structure that can be observed through the light microscope, histology also includes cellular detail down to the molecular level that can be observed using an electron microscope. The importance of

The images in this gallery show real cells under the microscope. Do they look like cell diagrams you’ve seen? Probably not! Most cell diagrams, whether in your textbook or online, are generic. They highlight a set of overlapping features that all cells need to live. But every cell also has unique features to do a specialized job.

2015年2月11日 · Microglial cells recognize areas of damage and inflammation and swallow cellular debris. The larger orange shape is an oligodendrocyte. The ragged extensions of an oligodendrocyte can supply many neurons (nerve cells) with myelin, an insulating material which allows each neuron’s communicating axon to transmit electrical impulses efficiently.

Histology is the study of the microanatomy of cells, tissues, and organs as seen through a microscope. It examines the correlation between structure and function. Histology Guide teaches the visual art of recognizing the structure of cells and tissues and understanding how this is determined by their function.

We will look at each type of microscopy in turn and explore their strengths and limitations. An example of each is included in Figure 01-01 for direct comparison in the same organism. We will also show more examples throughout the chapter.

Stem cells. Cells in the intestinal epithelium don’t live very long. This cell type divides to make more of them. New cells migrate from the bottoms of crypts to the tips of the villi.

To visualize most human tissues/cells using a compound light microscope, the tissue must be fixed/embedded, sectioned, and stained. Fixing and embedding is a process that preserves the tissue to prevent degrading and embeds it into a hard substance like …

Human Tissue Like a real microscope, the Virtual Microscope will allow you to examine slide samples more closely. Your teacher will give you instructions for how to record your observations.
