After an almost 2 1/2 year hiatus, the return episode covers the basics of the meninges and cerebrospinal fluid of the central nervous system.

Episode 23 - The Meninges And Cerebrospinal Fluid

This episode covers the brain barrier system that protects the brain tissue from harmful agents that can be found in our blood. I also discuss cranial nerves I–XII, their origins, and their functions. Dr. Kevin Petti, Professor at San Diego Miramar College, coauthor of the textbook "Visual A&amp;P" from Pearson Education, and the founder of Anatomia Italiana, https://anatomiaitaliana.com/, joins me to discuss  A&amp;P and his teaching program in Italy that connects art and anatomy.

Episode 22 - Brain Barriers And Cranial Nerves

Episode 21 begins our journey into the anatomy &amp; physiology of the human brain, beginning of course with anatomy! It also marks our first episode with a guest. Dr. Charles Welsh is not only a professor of Biology at Duquesne University, but he is also the author of Hole's Essentials of Anatomy &amp; Physiology, as well as a co-author on Hole's Anatomy &amp; Physiology (the majors-level text book), both published by McGraw-Hill Education. Dr. Welsh and I discuss teaching and writing about anatomy &amp; physiology as well as some important A&amp;P concepts that students need to get.

Episode 21 - Intro To The Human Brain

In this episode I continue on with the nervous system and spinal cord, discussing spinal nerves, plexuses, and reflexes. I also answered a listener's question about recommended books, like "Mader's Human Biology" by Dr. Michael Windelspecht and "Hole's Essentials of Anatomy &amp; Physiology" by Dr. Chuck Welsh. Both great resources by excellend authors and professors. You can also use my personal learning resources at www.aandponlinematerials.weebly.com.Send me your questions at minus55media@gmail.com.

Episode 20 - Spinal Nerves And Reflexes

This episode covers the spinal cord anatomy and a little bit of function. I also discuss how spinal tracts are named and I answer a question about myelination, nerve signal conduction velocity, and Multiple Sclerosis. You can get more valuable resources for learning Anatomy &amp; Physiology at https://aandponlinematerials.weebly.com/There you'll find lab materials, tutor videos on key concepts, dissection videos, etc. Good luck and be well!

Episode 19 - Intro to the Spinal Cord

This episode covers everything you need to know about the nerve signal. This includes the resting membrane potential in neurons as well as local and action potentials. I also discuss chemical synapses and neurotransmitters.Send me your questions at minus55media@gmail.com.

Episode 17 - Intro to the Nervous System and Nerve Tissue

This bonus episode isn't about any specific principle in human anatomy &amp; physiology. Instead, I am discussing the five rules of understanding A&amp;P. This is something I've been sharing with my students with years. I hope you enjoy it and it helps you.

Bonus Episode #3 - 5 Rules For Understanding A&P

This episode discusses the way neurons innervate skeletal muscles and they manner in which skeletal muscles shorten to move the skeleton, regulate movement of materials, etc. The neuromuscular junction is the union of a motor neuron and a skeletal muscle fiber. There are three phases to muscle contraction: excitation, excitation-contraction coupling, and sliding filaments. Finally after contraction, we have relaxation. All are covered in this one episode.

Episode 16 - Muscle Tissue Part 3

This episode covers the anatomy of skeletal muscle cells. From the sarcolemma to the sarcomere to the myofilaments, this information is crucial to understanding how skeletal muscle works.

Episode 15 - Muscle Tissue Part 2 (Cellular Anatomy)

"Anatomy &amp; Physiology - Bit by Bit" is not only intended for college students taking A&amp;P, it's for anyone who is interested in how the human body is structured and how it functions. Where students are concerned, the goal is "B or better." Whether you're interested in nursing, physical therapy, physician's assistant, radiography, etc, a B or better should be the goal to be competitive with other students in your field. Hopefully, these short, pointed discussions will help you understand what you need to be successful. minus55media@gmail.com

This episode discusses the three types of muscle tissue, the characteristics that all muscle tissue types share, the functions of muscle tissue, and its general structure.

Episode 14 - Muscle Tissue Part 1

Love the length of the episodes and audio quality... not to mention Dr. Sullivan&#39;s amazing teaching skills! This podcast is a huge gift to students everywhere from a professor who just loves to teach. 

I&#39;m in high school and have never taken an official A&amp;P course, but Dr. Sullivan makes the subject so accessible in this podcast. Can&#39;t wait to see more episodes!

So thankful for this podcast!!

Love this podcast, wish there were more episodes, hope you’re okay...excellent teaching, presentation &amp; sound quality.

Where are you, Dr Steve Sullivan?
