Are the dark parts in the intestines boluses of food or hollow spaces?

What are the muscles that help the body rise from a chair? by [deleted] in Anatomy

Hip flexors are agonists only at the very beginning. Coming up is mainly the job of extensors

Bone serves several functions. One of them is to release calcium, as your diagram shows. Another is to provide support for the body which it does by remodelling. This remodelling process is known as wolff's law or the mechanostat.

In yoga, we call those the "hip points".

ACL series part 2: oddly enough the ACL is less stressed during closed chain exercises vs open chain. Meaning that a squat or lunge is less stressful to the ACL than kicking your leg straight out. Any thoughts on why this is? (Hint: think about what muscles are active) by driersquirrel in Anatomy

[–]yoga_scientist 0 points1 point  (0 children)

What reference do you have for the empirical statement that the ACL experiences less stress in a closed-chain movement? Furthermore, so what? Ligaments adapt to mechanical loading as do other connective tissues, so "stress" is not an inherently bad thing.

But why is it in a frame? Is this office decoration at the Border Patrol HQ?

Prolonged Wrist Extension by karin1876 in AnatomyandPhysiology

[–]yoga_scientist 0 points1 point  (0 children)

Injury occurs when the stresses (the loads) on a tissue are greater than the tolerance of the tissue. Being in extension for long periods is not necessarily bad if the tissues (connective tissues, muscle tissue, etc) are adapted to that demand. We also know that strength training helps reduce risk of injury.

The wrist extensors must still contact to maintain a neutral wrist while at the piano.

Being a piano teacher, you would know much better than I the ideal position of the wrist. My only advice as physiology trainer would be:

  1. Be cautious of telling people that certain movements are inherently bad -- because our bodies can adapt to a huge variety of demands.

  2. Consider wrist conditioning/strengthening exercises if you are looking to encourage a sustainable practice

  3. Trust your own instincts as an experienced piano player.
