Basic Cellular Physiology: Fluid Compartments

Phys fluid compartments-page-001

Osmosis ‘Osmosis is the movement of water across a semi-permeable membrane from regions of low solute concentration to those of higher concentration’. Biological membranes are semi-permeable – they allow the free movement of water but restrict the movement of solutes. The creation of osmotic gradients is the primary method for the movement of water in […]

Basic Cellular Physiology: Homeostasis

Homeostasis is Greek for ‘staying the same’. In the context of human physiology the term homeostasis describes the maintenance of nearly constant conditions in the internal environment – physiological self-regulation. All organs and tissues perform functions that help to maintain this constancy – it is a coordinated, dynamic process. Disease can be conceptualised as a […]

Upper Limb Anatomy: The Axilla

The axilla

The axilla (armpit) is the zone of transition from the neck to the upper limb. It lies underneath the glenohumeral joint and has an irregular conical shape – like a tilted pyramid. The axilla is the passageway for the neurovascular bundle from the neck to the upper limb. Main contents of the axilla: Axillary artery […]

Hunting the Culprit 2: Coronary Artery Anatomy


This is the second post from the ‘Hunting the Culprit’ Series.  An appreciation that each of the 12 ECG leads is a ‘snapshot’ of the heart from a specific position is crucial for hunting the culprit vessel in STEMI patients. For a detailed explanation of ECG leads, here is the first post from this series […]
