Atria & Auricles

The atria have out-pouches called auricles (= 'ears'). These are visible mostly from the anterior view of the heart. Internally, the auricles of the atria contain mostly pectinate muscle.

Intercostal Catheterisation: Applying Body Wall Anatomy Clinically

You’ve explored the anatomy of the thoracic wall in lectures and examined it through dissection specimens. Now, we’ll apply that knowledge in a clinical context by looking at intercostal catheterisation using the anterior approach. This procedure is commonly used to drain air (such as in a pneumothorax) from the pleural space. Understanding the body wall layers, their spatial arrangement, and surrounding structures is essential for performing this technique safely and effectively.

Use Lecture 8 "Anatomy of Body Wall" as your guide

Image failed to load: thorax image for intercostal catheterisation

Instructions:

Using the image of the donor specimen with an intercostal catheter in situ,

label the anatomical layers that the catheter passes through in the anterior approach, from the skin to the lung tissue. Each correctly labelled structure is worth the mark indicated.

Structure to Label (from superficial to deep)Marks
Skin1 mark
Superficial fascia (subcutaneous tissue)1 mark
Skeletal muscle (e.g. pectoralis major, intercostal muscles)1 mark
Rib1 mark
Parietal pleura1 mark
Pleural cavity1 mark
Visceral pleura1 mark
Lung tissue1 mark
