Thank you!

You’re very welcome!

Thank you!

I have videos of all different lengths, but I try to keep them short and specific. Some of my Biomechanics videos are a bit longer. Biomechanics has a lot of crossover with Functional Anatomy, so you might want to check out my Biomechanics playlist: th-cam.com/play/PLfmSdQnYkFK-Zja_ANjkW3nXlcwsgrgGo.html

Thanks for asking, and I’m glad you love my videos. I am aware of your request and I try to throw in neuro videos here and there, but my priority is always topics that I need for my current students. I will continue to sprinkle in neuro topics when I can 🌞

Thank you

Haha 🤪

Thanks so much for your support! 🌞

Thanks so much for the feedback! I’m really glad that my lectures are helping you. Thanks for watching! 🌞

Thanks so much!

I’m great, thank you! I will always keep coming back, I plan to make these videos forever. Thanks for watching! 🌞

Great question! They are very similar but don't mean the exact same thing. Tropic hormones are hormones that act on another endocrine gland or tissue to cause secretion of another hormone. Trophic hormones are hormones that act on another endocrine gland, tissue, or cell specifically to affect the growth, function, or nutrition of the cells it is acting on. So both tropic and trophic hormones act on other endocrine glands and tissues, but tropic hormones cause release of another hormone and trophic hormones cause an effect like growth in the target gland. I hope that helps!

@@DrVeronicaFoster Thank you for your selfless service

​@@DrVeronicaFoster clear mam 😊

Good advice!

Thank you!

Thanks so much for your feedback! I’m glad that you’re understanding DST better now, and I’m really happy that I was able to help. Thanks for watching! 🌞

Yes, exactly. The more mechanically disadvantaged the muscle (shorter moment arm), the harder the muscle has to work to overcome the disadvantage by producing more force.

Thanks so much!

Thank you for the feedback, I’m sorry it wasn’t what you were looking for

Thanks so much, I appreciate it 🌞

Wow! Thanks so much for the feedback, you made my day 🌞

Thank you!

Thanks for sharing! What are you going to do to change it?

@@DrVeronicaFoster I'm not sure? A guy on TH-cam suggests a cold shower, short nap, or a cup of coffee

You’re welcome!

I hope it helps!

Hi there, a great way for most people to reduce cortisol is with exercise. To lower cortisol, the root of the problem needs to be addressed. If cortisol is high due to chronic daily stress (not an isolated situation), then exercise can help tremendously. When the body is chronically in a fight-or-flight state, good, hard, exercise can help the body "close the loop" on the stress response. Think of it like you are tricking your body into thinking that the stressful event is over by exerting physically like you would if you were fighting or fleeing from the stressor. If cortisol is high due to other reasons (besides chronic stress), then medical intervention might be needed. In that case, it is a good idea to talk to your doctor to determine the root cause and a treatment plan. I hope this helps!

I looked into grounding. I watched grounding movie on TH-cam. I spend time on my lawn (no weed killer, etc) and I also use a grounding mat. I can’t do without it. It helped me lower my cortisol and sleep better.

Hi there, thanks for asking. Not all stretching is an eccentric contraction. It is an eccentric contraction when the muscle is lengthening while it’s contracting, as is the case during the “stretch” phase of the stretch-shorten cycle. Here is my video about muscle contraction types if you’d like to learn more: th-cam.com/video/iRaU9FB2oh0/w-d-xo.htmlsi=0I8RZmQ2XmxTnpf1

That is so kind of you, I really appreciate it!

Hi there! Mechanical advantage is determined simply by the lengths of the different moment arms. There are many factors that determine the forces acting at the different points on the levers (like muscle size, length-tension relationship, and so on), but it doesn't change the mechanical advantage. Each muscle will have a different moment arm at a joint since the insertions will be located at slightly different points, so different muscles will have a different mechanical advantage during different actions, which is part of what determines which muscle is the prime mover in an action. The many variables that factor into the amount of force a muscle can exert on the bone are what allow muscles to overcome their mechanical disadvantage (in the majority of cases). How much force a muscle produces doesn't change its' mechanical advantage, it just means that they are producing enough force to overcome the disadvantage they are at due to their moment arm. I hope this helps, and thanks for watching!

You’re welcome! I’m so glad I could help

Thanks, you too!

Thanks for asking! Cerebral blood flow can be observed using cerebral perfusion imaging, carotid duplex, or cerebral angiogram. Cerebral perfusion imaging is done with an MRI, CT PET, or other types of imaging. Arterial spin labeling (ASL) is a specific type of MRI technique that is commonly used for measuring cerebral blood flow non-invasively, especially for TBI. Carotid duplex can be used to look for problems in the carotid (which would limit blood flow to the brain) using ultrasound. Cerebral angiogram is where they insert a catheter into an artery and inject contrast dye, then take an x-ray of the blood vessels. I hope this helps, and thanks for watching!

You’re very welcome, thanks for watching!
