Anatomy and Physiology - Bit by Bit

Episode 24 covers the largest part of the brain, the cerebrum. But first, my conversation with Dr. Bee Heeney-Stemple, professor of Anatomy & Physiology at Bucks County Community College (where I teach!). Dr. Heeney-Stemple has been researching the effect of stress, anxiety, and Post-Traumatic Stress Disorder (PTSD) on learning, including techniques to counteract those effects to maximize student and instructor success in the classroom. These 5 steps are: 1. Get to know your students and create a safe learning environment. 2. Sustain communication and be constant in your support, encouragement, and awareness to prevent crises. 3. Be flexible and accommodate. 4. Know your institutional services. 5. Obtain professional development on PTSD. If you have any questions please email me at minus55media@gmail.com.

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.

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&P" from Pearson Education, and the founder of Anatomia Italiana, https://anatomiaitaliana.com/, joins me to discuss A&P and his teaching program in Italy that connects art and anatomy.

Episode 21 begins our journey into the anatomy & 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 & Physiology, as well as a co-author on Hole's Anatomy & Physiology (the majors-level text book), both published by McGraw-Hill Education. Dr. Welsh and I discuss teaching and writing about anatomy & physiology as well as some important A&P concepts that students need to get.

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 & 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.

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 & 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!

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.

This episode is a little longer than usual and covers the basics of the nervous system and the anatomy of neurons and nerve tissue. It is an essential introduction to the nervous system. I hope you enjoy it.

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

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.

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.

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.

This episode covers the embryonic formation of bones and how bones grown after birth.

This episode covers the difference between compact bone and spongy bone, Wolff's Law, and calcium homeostasis.

Is blood blue? How many ribs do men & women have? Do we really have 5 senses? What's so funny about the funny bone? This bonus episode is dedicated to dispelling four common myths people believe about the human body. Inspired by a listener's email, I hope you enjoy busting these myths!

This episode introduces the skeletal system with a topic overview and discussion of the histology of osseous tissue.

This episode explores the physiological basis of skin, hair, and eye color.

This episode covers the general basics of the integumentary system including functions, the cells and layers of the epidermis, the dermis and cutaneous glands, and superficial wound healing. Feel free to send me your questions to be answered on future episodes: minus55media@gmail.com

This episode covers the study of tissues, histological sections, and the four primary tissue classes.

This bonus episode is a discussion about the novel coronavirus and COVID-19. I discuss what a virus is, how it's spread, what countries currently have cases, what the symptoms are, how you can prevent getting it, and what to do if you contract the virus.

This episode covers DNA replication and the cell cycle.

This episode covers DNA structure and protein synthesis.

This episode is a brief overview of the cytoplasm.

This episode gets specific about diffusion, osmosis, and carrier-mediated transport across the cell's plasma membrane.

This episode introduces the cell and discusses the plasma membrane in detail.

This episode covers the main principles of homeostasis, the way our bodies maintain a consistent internal environment despite living in an inconsistent external environment. Negative and positive feedback systems are discussed.

This episode discusses the difference between anatomy and physiology as well as the way the human body is organized from atoms all the way up to the whole organism.
