Injections that stop pain are an amazing thing. How do local anaesthetics stop pain? What makes the numbing effect wear off? And what should be done if it doesn’t? A thread on nerve function by a nerve surgeon. #regionalanaesthesia #localanaesthetic #neurapraxia #conductionblock Firstly what do nerves do? Nerves control all functions of the body. They control movement of muscles, bring the sensitivity to touch and temperature to skin, they control sweating, hair and nail growth and….

Oh, noble nerve, most precious and delicate of cords!
Thou art the messenger, the conductor of all sensation,
The vital link between body and brain,
The very essence of life's electrical impulse.
But alas, when thou art damaged or severed,
The body is left numb the mind unseeing The spirit unfulfilled, the soul unfulfilled.

Thus, in times of crisis, we turn to thee,
Nerve graft, the savior of the damaged nerve,
The healer of the broken connection.
Thou art the bridge, the conduit, the lifeline A thread of hope, a ray of light in the darkness.

Open water swimmers and winter people all, do you wonder how you feel cold? Well it’s the wonder of nerves again - let me tell you some nerve nerdy stuff... #openwaterswimming #thestoics #sensorynerve #cold
A thread : Cool is a pleasurable feeling and warm too but hot and cold break into painful feelings. This appreciation of temperature is a protective function of nerves but how does it all work? How does your body tell your brain about the word outside?

Let me introduce you to this amazing structure. It scares many people who learned it as medical or paramedical student, but to me it’s wonderful clever & beautiful. A triumph of developmental neurology and essential in all we do- let me introduce the brachial plexus via a thread The brachial plexus is a mixing and crossing of nerves (that’s what plexus means) which controls the whole arm (which is what brachial means). This beautiful picture was drawn by @artibiotics and is the map for our story.
