Spinal tracts are bundles of neuronal axons that run through the spinal cord and brainstem. If we think about how neurones work, how they are bundled together with similar functions, which direction the action potentials are running in and the names of these tracts, we can remember what they all do.

Referred pain is felt at a different location in the body from the site that is causing the pain. There seems to be an anatomical reason for this and understanding the theories can help with diagnosis and patient care.

Talking about the anatomy of the urethra and better understanding why women get more urinary tract infections than men.

The radial and ulnar arteries both supply blood to the hand and meet as two arches that send branches off to the fingers. This anatomy gives redundancy for the blood supply to the hand so let's talk about where these arteries run and how they branch.

The names of the movements of the thumb can be tricky to remember, but knowing the movements gives you the names of the muscles that cause these movements.

Relating the movements of the hand to the nerves responsible is an important clinical skill. Let's see if I can describe the movements of the wrist and fingers, and the nerves that trigger these movements in 5 minutes.

The anatomy of erection of the clitoris and the penis is very similar and a rather neat mechanism involving the parasympathetic nervous system.

Did you know that alongside the pulmonary arteries taking poorly oxygenated blood to the lungs run bronchial arteries carrying well oxygenated blood? Where do they come from, and where does this blood go to?

The ureters carry urine from the kidneys to the bladder, and are muscular tubes lined by a urothelium. They use peristaltic contractions to send the urine in the right direction so do not rely on gravity, and because they run from the mid-abdomen down to the true pelvis they receive a number of arterial branches as they travel and likewise use nerves from a number of spinal levels to send the pain of a kidney stone obstruction back to the brain.

The kidneys manage the amount of water and salts in the body, regulate blood pressure, stimulate red blood cell synthesis, and remove toxins among other jobs. Let's talk about the key points of their anatomy for 5 minutes.
