In Episode 20, Dr. Matt & Dr. Mike go through the 12 pairs of cranial nerves!
They explain how to remember their names! How to remember whether they are sensory, motor, or both! AND how to test them clinically!!
Here we introduce the anatomy, physiology, and pharmacology of the autonomic nervous system. After finding out what Dr Matt did in India, we explore why we have a sympathetic (fight or flight) and parasympathetic (rest and digest) division of the nervous system. We look at cholinergic receptors and adrenergic receptors and where they are located. And finally, what drugs can do to alter these systems - enjoy!!
In order for our neurons to fire off, heart muscle to contract, and kidneys to reabsorb substances, the cells in our body need to establish charge and concentration differences between the inside of the cell and outside the cell (resting membrane potential). In this episode, we explore how our body creates these differences and exploit them to send signals to and from the brain (action potential). We also discuss what can happen to the body if we alter these concentrations and charges.
In this episode Dr. Matt and Dr. Mike introduce the nervous system. They outline the various components of the central nervous system (brain and spinal cord) and peripheral nervous system (cranial nerves and spinal nerves) and discuss its primary functions. Dr. Matt also explains to Dr. Mike the embryological development of the nervous system.
