The practice of Neurosurgery engages mainly with the spine and brain. It’s a medical speciality which is concerned with the diagnosis and treatment which affect any parts of the nervous system including the brain, spinal cord, peripheral nerves and extra-cranial cerebrovascular system.

In this video Farhdad M. Limonadi, M.D. did an amazing job in the beginning of the video. His precision cuts and incision in the beginning of the removal of a bone flap was so satisfying to watch. Once the brain was exposed you could see the melanotic tumor in the right upper corner. This was a successful surgery and Limonadi did a great job.


After watching the video, I had questions just like anybody else would. And there was no one around to answer them for me so I searched and searched online to find answers…..

What are the peripheral nerves?

The Peripheral nervous system is a network of 43 pairs of motor and sensory nerves that connect the brain and spinal cord to the entire human body.

I. It’s main function is to connect the central nervous system to the limbs and organ, serving as communication bouncing back and forth between the brain and spinal cord with the rest of the body.

II. Unlike the CNS (central nervous system), the PNS (peripheral nervous system) is not protected by the bone of spine and skull, or by the blood-brain barrier.

III. The Peripheral nervous system is mainly divided into the somatic nervous system and the autonomic nervous system.

A. The Somatic Nervous System is associated with skeletal muscle voluntary control of body movement. The Skeletal Muscle is one of three major muscle type, the others being cardiac muscle and smooth muscle.

1. The SoNS consist of afferent nerves and efferent nerves.

- The Afferent nerves are responsible for relaying sensation from the body to the central nervous system

- The Efferent nerves are responsible for sending out commands from the CNS to the body.

B. The Autonomic Nervous System influences the function of internal organs. It’s a control system that acts largely unconsciously and regulated bodily function such as the heart rate, digest, respiratory rate, pupillary response, urination, and sexual arousal.

All this information was found in the links below. What I learned from all this which was very significant was the fact that you don’t need a teacher, an hour long course, 12 other students, and a table to learn. Learning is unique and different in its own ways.
