The Pharmacist Answers Podcast

Your health is probably one of the most important things to you.  Yet it can be one of the most complicated things to understand.  Our bodies are meant to work a certain way, but when they don't, we may never be 100% sure why or what to do about it - even after seeing a healthcare professional.

The Pharmacist Answers Podcast is hosted by Cynthia Hendrix, PharmD.  On the Podcast, you can learn the basics of body parts and organ groups, get a glimpse of how disease processes work, and learn some practical steps to take in your own flesh and blood relationships with healthcare providers.

Everyone's health story is different.  No one is truly a "textbook case".  You need someone who sees your uniqueness and help you gain the knowledge and confidence to have conversations, ask questions, and make decisions that are right for YOU!

*The Podcast started out as live conversations on Periscope.

Brainstem Basics

Your brainstem is the most basic area of the brain.  The area of the brain that we have in common with almost all other levels of the animal kingdom.  It extends right into the spinal cord.  A lot of other whole body involuntary reflexes come from the spinal cord - that's another story for another day).

3 main parts

  • Medulla oblongata - rhythm center (heart rate, breathing, swallowing, vomiting and coughing reflex) - they're all involuntary
  • Pons (not ponds) - the bridge between the cerebellum hemispheres and other brain regions, helps coordinate the right side and left side of your body for complex activities
  • Midbrain - sensory reflexes (also involuntary) - blinking, eye focusing, pupil dilation in response to light, visual and auditory startling reflex that kick-starts the "fight or flight cascade".

Other eye focusing problems are not rooted in the midbrain. They are more likely rooted in the areas of the brain that control orbital muscles or in the areas that translate what your eyes are seeing, like a "lazy eye" or drifting eye or being cross-eyed.  There are therapies that doctors prescribe to try and strengthen the weak eye.  Blinking is usually a response to eye moisture.
