This Week: The Hamstrings and Quadriceps Femoris, The Group of Three and the Group of Four
Dr. Dan Rovin, DC
is a senior faculty member at The Healing Arts Center in St. Louis, Missouri and at Southwest Illinois College in Belleville, Illinois. He teaches anatomy and physiology in the massage therapy program at HAC. He has helped train more licensed massage therapists in the region than probably anyone. "Dr. Dan" , as his students call him, is known for breaking down the hard science of anatomy and physiology into easy to understand, often humorous presentations to make this essential science memorable.
The English-speaking world calls them the "hamstrings". I refer to them as Biceps Femoris and the Semi Sisters. They work against the muscle group most commonly known as the quadriceps. I teach them as Rectus Femoris and the Vastus Brothers. Together they are the seven muscles that are most responsible for the movements of the knee. More importantly (since we stand, walk, run, and jump), they are the seven muscles most responsible for fixating the knee and preventing falling due to knee instability. Let’s break them down.
This Week: ILIOPSOAS – THE GROUP OF TWO
Last month I introduced the sartorius muscle as the “group of one”. It was the first of six, really seven, groups of thigh muscles that I have, or will be blogging about. In keeping with counting order allow me to discuss the “group of two”, iliopsoas. Unlike the intentionally misnamed “group of one”, which is a singular muscle and should not be considered a group, “the group of two” is comprised of two distinct muscles. They are iliacus and psoas major.
This Week: The Sartorius Muscle
Over the next several months we are going to explore the twenty-five muscles of the thigh. Each month we will break down and explore a group of muscles responsible for hip and knee movement. If you have been following Danatomy blogs through the HAC website, or Facebook, you might remember that the very first blog was over the "Deep Six" muscles of the buttock. In the classroom I refer to them as the "group of six". I also discuss the "group of five", the "group of four", the "group of three", the "group of two", and the intentionally incorrectly termed "group of one". As such allow me to introduce you to sartorius - "the group of one".
