Cell Unit for Anatomy and Physiology
This chapter focuses on cell structures (organelles), cell division, and cell membranes and transport.
For anatomy students, this will mostly be a review of what was learned in first year biology.
The slide presentation has a case study focus on a fictional girl who has recurring ear infections, and pneumonia. An X-ray reveals she has her internal organs are reversed - situs inversus.
As students learn about the cell, they gather clues about what could be wrong with the patient.
The Case Study
Primary ciliary dyskinesia (PCD) is a rare genetic disorder that affects the cilia, which are tiny, hair-like structures found on the surface of cells, particularly in the respiratory tract, ears, and reproductive system. These cilia play a crucial role in moving mucus, bacteria, and other substances out of the airways, helping to clear the respiratory tract.
In individuals with PCD, there is a defect in the structure or function of these cilia, leading to impaired movement. As a result, mucus and debris cannot be effectively cleared from the respiratory system, leading to chronic respiratory issues such as:
- Chronic cough
- Frequent respiratory infections, including sinusitis, bronchitis, and pneumonia
- Recurrent ear infections
- Nasal congestion
- Difficulty breathing
PCD can also affect fertility in both males and females due to abnormalities in the cilia of the reproductive system.
Diagnosing PCD often involves a combination of clinical evaluation, specialized tests like nasal nitric oxide measurement, electron microscopy to examine ciliary structure, and genetic testing to identify specific gene mutations associated with the condition.
