Thanks so much for the suggestion!

It can change depending on the context or specific situation, but most often the motive force is muscle force and the resistive force is gravity

Haha, thanks! I’m so glad I could help

Are you sure it didn't say that PRL is trophic? The terms tropic and trophic are commonly used interchangeably even though they don't mean the exact same thing, and this adds to the confusion. Many sources will use either term to mean the same thing, which is very confusing because these terms have different meanings. Based on the traditional definitions of tropic and trophic, prolactin would be considered a trophic hormone because it stimulates the growth and development of the mammary glands, and not tropic because it doesn't stimulate the release of another hormone. Mammary glands are exocrine glands, not endocrine, and they secrete milk, not a hormone, so stimulation of the mammary glands does not qualify prolactin as a tropic hormone. I hope this helps, and thanks for watching!

Thank you!

Hi there, thanks for asking! A tropic hormone is a hormone that acts on some other endocrine gland or tissue to cause it to secrete another hormone. A trophic hormone specifically stimulates growth in target tissues. The same hormone can be both a tropic hormone and a trophic hormone. For example, thyroid-stimulating hormone (TSH) both stimulates the thyroid to release thyroid hormone (tropic) and stimulates growth in the thyroid itself (trophic). I hope this helps, thanks for watching!

@@DrVeronicaFoster Can prolactin be considered as a trophic hormone? because it acts on the mammary glands and stimulates its growth

@prabhudhm9332Yes, exactly! Prolactin is a trophic hormone because it stimulates growth, but not a tropic hormone because it doesn’t stimulate release of another hormone

@ Thank you so much!

Yes, it is!

But GH is not stimulating any other endocrine gland ​@@DrVeronicaFoster

@@karishmarawat6510​​⁠it is stimulating the release of another hormone (IGFs) from endocrine tissues throughout the body, so it is a tropic hormone

Hi there, you might like to start with your general practitioner, and see what they recommend based on your specific situation. In terms of specialists, a neurologist or orthopedist could probably both help you. Which is more appropriate depends on your specific situation, so hopefully your GP can help you decide the right course. Best of luck to you!

Thank you 😊

You’re welcome, thanks for watching!

You’re very welcome, and thanks so much!

I’m so glad you like my video, thanks for watching! I’m not available to chat, but if you’d like to learn from me I have hundreds of videos on my channel, and you can ask your questions in the comments. I answer the comments as quickly as I’m able. Thanks for watching!

I think you’ll have to decide that for yourself once you read the syllabus

Hi there, thanks for the question! There are many different types of carbohydrates in the body, and hyaluronic acid is one of them. Hyaluronic acid is a specific carbohydrate that retains water, and is what helps keep things like our joints and skin hydrated and lubricated. That's why you see this ingredient in all sorts of skin products. Thanks for watching!

@DrVeronicaFoster tq.. What foods helps increase hyaluronic acid in body inside out

You’re welcome, and thanks for the feedback!

Yes, correct! 1g of carbohydrate has 4 kcal, which is 4,000 cal, or 4 Cal (big C) as we use it in the US

@@DrVeronicaFoster so if someone say i burnt today 300 calories then what they have actually burnt is 300k calories? omg.

Yes, the pennation angle can change dramatically depending on the degree of contraction of the muscle. That is one of many variables that affects the amount of force a muscle can produce based on its current amount of contraction/length/position. With that said, consider that pennate muscles have less excursion (they cover less distance between their totally relaxed and totally contracted states), so pennate muscles are less affected by their degree of contraction than longitudinal muscles, despite the fact that the pennation angle is less in the muscle's favor as the muscle shortens. Thanks so much for watching and asking such interesting questions!

Yes, your logic here is sound and you're thinking about this the right way. To clarify though, the angle of pennation is rarely as high as 45 degrees. Logically, what you described here is accurate, but in reality, the angle of pennation is more slight than this, so the "canceling out" of forces, is much less than the way you described it here. Soleus has the highest degree of pennation, and on average it has around 25-30 degrees of pennation. Most other pennate muscles have a much lower average angle of pennation. Because a pennate muscle can pack in so many more muscle fibers than a longitudinal one, a pennate muscle can more than make up for the "canceling out" of the fibers on opposite sides. I hope this helps, and thanks for watching!

Thank you! 🌞

Thanks so much, I really appreciate your support!

Thanks for your feedback! You’re welcome 🌞

Thank you, I’m glad to hear that!

I wish I could help, but I’m an anatomy professor, not a vocal coach. Good luck to you!

The PCL is made up of two bundles. One slacks during extension while the other is taught, and vice versa during flexion. The two bundles function synergistically to control posterior tibial translation and rotation throughout a wide range of motion. Here’s a great paper if you’re interested: pmc.ncbi.nlm.nih.gov/articles/PMC6105479/

@DrVeronicaFoster okay, but it's not applicable here, right? Because the screw-home mechanism depends on 3 factors and the passive tension of ACL is one of them as it prevents the excessive anterior translation of tibia during extension, and because of this tension the ACL pull the tibia into external rotation. I mean it's more important than the PCL which is most important role to resist flexion, am I right??

I read the article it's great thank u, AMB assists the ACL with external rotation during extension

@@omarkassab6424I don’t know if I’d say the ACL is more important than the PCL during extension. They’re both relevant and they work together to stabilize the knee in extension

Hi there! Yes, a high-grade ligament sprain is equivalent to grade 3, and is a complete or near-complete tear. I hope you heal quickly!

@@DrVeronicaFoster Ouf... Understood. Last question... For longevity of the ankle, and especially as a stunt performer, do you recommend surgery? Or just let it be and hope I don't roll it again to completely tear it? And if it is torn completely, it would require surgery anyway? Correct?

@@TrevorBodogh Sorry, but these are questions that you should be asking your doctor. Good luck to you, I hope you get the answers you need!

You’re very welcome!

Thanks so much!

A “tropin” is a tropic hormone. They mean the same thing 🌞

@DrVeronicaFoster ok mam 😊

💓

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! 🌞

You’re welcome! Thanks for watching 🌞

Thank you!

Hi there, cortisol has a direct inhibitory effect on norepinephrine, meaning that as cortisol increases, norepinephrine generally decreases. In contrast, cortisol does not have this inhibitory effect on epinephrine. Although cortisol doesn't directly inhibit dopamine, high levels of cortisol can interfere with dopamine production. Even so, cortisol has the greatest effect on norepinephrine compared with epinephrine and dopamine. I hope this helps!

You’re welcome, good luck!
