ANAT2511 Fundamentals of Anatomy This histology practical support page content is not part of the histology practical class and provides only background information for student self-directed learning purposes. Histology lecturer notice. |
Objectives
- To learn how to use virtual microscopy for studies in histology and to recognise parts of a cell and common features of cells and tissues.
- To recognise common features and differences between cells (e.g. size, shape, nuclear appearance, secretory components, microvilli and cilia).
Reading
Human Anatomy, Marieb et al., 6th ed., pages 23‐46
Learning Activities
- Examine the following virtual microscope slides and find examples of cells of different sizes and shapes.
- Virtual Microscopy - Cells and Types of Tissue (6 slides)
- The image links are located in the ANAT2511 folder on the computer desktop.
- Identify examples of the following cellular components: nucleus, nucleolus, densely packed rough endoplasmic reticulum (rough ER), microvilli, and cilia.
Blood Smear
The images below show some of the types of cells found in the normal blood.
- Note that the white blood cells all contain a nucleus (stained blue), while the red blood cells have no nucleus only cytoplasm (stained pink).
- The white blood cell nucleus can also have different shapes in different cells.
- Red blood cells also appear as "donuts" as they are thinner in the centre and thicker at the periphery.
- When the cytoplasm is thicker the staining appears darker, when the cytoplasm is thinner the staining appears lighter.
The following image is a scanning electron microscope image of a red blood cell (erythrocyte), a platelet (thrombocyte) and a white blood cell (lymphocyte).
- Electron microscopes have a higher resolution than a light microscope (virtual slides).
- Image shows the relative cell sizes and shapes (morphologies).
- Remember a platelet (thrombocyte) is not a cell, but circulating part or a fragment of a cell.
Spinal Cord
