Chronic Stress

Chronic stress can cause a patient to feel irritable, moody and have restless sleep. Stress is not always bad, it can help one to stay patient, focused. However, stress over a prolonged period of time can affect brain size, structure, shape and how it functions. 

Under stressful situations, the adrenal gland releases cortisol which activates your body for instant action. This explains why we feel a surge of energy under stress. However, high levels of cortisol over a prolonged period of time increases the level of activity and neuro-connections in the amygdala, also know as your brain’s “fear centre”. 


With high levels of cortisol, your brain’s hippocampus-the part of your brain responsible for stress control, reading and learning- deteriorates, and hence your ability to control stress. 


Abnormal levels of cortisol can also reduces the synapses between neurons and cause shrinking of the pre-frontal cortex. This affects concentration, decision-making and judgement.

Horner’s Syndrome

Horner’s syndrome is a condition where the sympathetic nerves on the face are damaged. 3 classic signs of Horner’s syndrome include miosis (constriction of the pupil), ptosis (drooping of the upper eyelid) and anhidrosis (absence of sweating of the face). It is a result of other medical problems such as stroke, tumor or spinal cord injury. Hence, treatment for the underlying issue may restore nerve function. The nerve pathway affected in Horner’s syndrome is divided into three groups of neurons called the first, second and third order neurons. These neurons lead from the hypothalamus of the brain through the spinal cord and finally along the facial skin and muscles of the iris and eyelids  Sources: https://rarediseases.info.nih.gov/diseases/6670/ horners-syndrome

Kidney Stones

Renal calculi, or kidney stones is the formation of crystals in the kidneys causing excretory issues. These stones mainly form in the renal pelvis or the ureter in the kidney. It is accompanied by symptoms such as nausea, vomiting and a burning sensation when urinating  Urine consists of salts and various compounds such as Calcium, Potassium, Sodium, Oxalate, Phosphate and Uric acid. Calcium oxalate is the most common stone formed in the kidneys, it accounts for 80% of kidney stones The crystals can scratch the walls of the urinary tract, sending nerve impulses to the brain causing excruciating abdominal pain. The scratches also cause blood vessels embedded behind the walls to burst, causing blood to enter the urinary system. This causes the patient to urinate blood. IF the stone is big enough to cause a blockage in the urinary tract, this can create a backflow of urine and infect the kidneys itselves. However, most kidney stones do not grow large enough to cause a blockage. This w...

Cardiac Automaticity

Cardiac automaticity is the intrinsic ability of the heart to spontaneously depolarise, sending action potentials throughout heart muscles and myocardium. Unlike most organs in the human body, it does not require a nerve impulse to contract.  Surrounding the heart are nodal cells which send electrical signals throughout the heart. They comprise the following nerves in order: SA node, AV node, bundle of His, left and right bundle branches and the Purkinje fibres. The SA node (sinoatrial node) is the “pacemaker” and sets the rhythm for the heart. It sends action potential throughout the nodal cells, causing the myocytes to contract. This ability of intrinsically contracting is what makes heart transplants possible. Thus, only oxygen is needed to be supplied so that it can “live” outside the body. https://www.livescience.com/44460-heart-facts.html https://youtu.be/1kX6Tp8CWFw
