Introducing the most Massive and Strongest (in most ways) Bone in the Human Body
There are 62 bones in the legs: 10 trunk/hip bones, 14 ankle bones, and 38 foot bones. The femur (thigh) is the largest and strongest of these bones. Most land mammals capable of jumping also have femur bones, also lizards, frogs, and other tetrapod vertebrates. Its length on average is 26.74% of a person’s height, a ratio found in both men and women and most ethnicities with only restricted variation.
A Few Femur Bone Stats
- the Femoral neck sits at a 125 degree angle
- Femurs can resist 1,800-2,500 pounds of stress
- Vehicular accidents are the primary cause of breakage
The Great Trochanter is a large, irregular, quadrilateral eminence on the upper portion of the femur bone. This portion of the bone has several, extremely important muscle insertions for the thigh and hip bones:
The lateral surface, quadrilateral in form, is broad, rough, convex, and marked by a diagonal impression, which extends from the postero-superior to the antero-inferior angle, and serves for the insertion of the tendon of the gluteus medius.
Above the impression is a triangular surface, sometimes rough for part of the tendon of the same muscle, sometimes smooth for the interposition of a bursa between the tendon and the bone. Below and behind the diagonal impression is a smooth triangular surface, over which the tendon of the gluteus maximus lies, a bursa being interposed.
The medial surface, of much less extent than the lateral, presents at its base a deep depression, the trochanteric fossa (digital fossa), for the insertion of the tendon of the obturator externus, and above and in front of this an impression for the insertion of the obturator internus and superior and inferior gemellus muscles.
The Lesser Trochanter
The Lesser trochanter is on the underside of the femoral head and also has several muscular insertions: The Psoas Major on bottom and the Illiacus on top.
The Femoral Head is the highest part of the femur bone, support by the femoral neck. It inserts as a ball/socket joint into the Hip/Ilium via the structure depicted to the right.
The Femoral Neck
The Femoral neck usually sits at a 120-135 degree angle with some variation. A fracture of this area is known as a hip fracture and happens during aging. This structure supports the head of the femur bone and its insertion into the hip.
The Shaft of the femur is somewhat curved and has a protruding ridge called the linea aspera (rough line). The area of the bone supports the strongest muscle tissue in the body, including the hamstrings, Quadriceps, and thigh musculature. The Vastus Laterallis (outer quadricep) and adductor magnus (inner thigh muscle) connects into the linea aspera.
Lower Portion of the Femur
The Lower portion of the femur bone consists of two condyle (from the Greek word for knuckle), lateral and medial that create the surface for the upper tibia bone and the knee-joint. Coated meniscus tissue layers on top of the bone and provides synovial fluid for frictionless movement within the knee. The medial (inside) condyle is the larger than the lateral due to its increased weight-bearing.
How the Femur Bone affects your Holistic Health
Femur bone fractures correlate with increased disease in the elderly. It is safe to say that the femur bone is an organ that houses much of the mineral deposits for the body. Therefore, as we age and the bone tissue become more porous, this bone become one of the primary areas of decomposition.
One of the primary aspects of bone health is acquiring enough calcium to maintain bone density. Most calcium is available via leafy green vegetables, notably kale, bok-choy, and broccoli. Sodas and carbonated beverages make it harder for the body to absorb calcium and should be avoided by those with osteoporosis (orthoinfo.com). Vitamin D is an important catalyst for absorbing calcium into the bloodstream.
Phosphorus is another vital nutrient to maintain bone health. Nuts, Sesame Seeds, peanut butter, parsley, crab and prawns are all foods high in phosphorus. Don’t feel like you have to eat meat or drink milk to get these essential nutrients.
