The eye socket is not merely a cavity, which, when filled up with local anesthetic agent constitutes an eye block. This tutorial takes an in depth look at the nerves that innervate different parts of the eye and also the barriers that separate them.
Because all the visceral pain from the pelvis and abdomen goes via the sympathetic ganglia and then the sympathetic nerves to the spinal cord and brain, the ganglia are described in detail in this tutorial.
This is a succinct by essential description of the anatomy of the femoral, obturator and lateral femoral cutaneous nerves. This is a succinct by essential description of the anatomy of the femoral, obturator and lateral femoral cutaneous nerves.
The knee joint receives its innervation from at least 7 nerves that we know of. This innervation is described here in detail, which will explain why certain popular blocks for knee surgery is worse than useless.
For this month of December we will continue with our theme of micro-anatomy of nerves but emphasize the very related topic of why continuous peripheral nerve blocks (CPNB) fail.
