The nutrient canal (foramen) is directed away from the growing end of bone. The growing ends of bones in upper limb are upper end of humerus and lower ends of radius and ulna. In lower limb, the lower end of femur and upper end of tibia are the growing ends. [1] The nutrient arteries along with nutrient veins pass through this
The nutrient artery enters via the nutrient foramen from a small opening in the diaphysis. It invades the primary center of ossification, bringing osteogenic cells (osteoblasts on the outside, osteoclasts on the inside.) The canal of the nutrient foramen is directed away from more active end of bone when one end grows more than the other. When ...
The nutrient artery (arteria nutricia, or central artery), usually accompanied by one or two nutrient veins, enters the bone through the nutrient foramen, runs obliquely through the cortex, sends branches upward and downward to the bone marrow, which ramify in the endosteum–the vascular membrane lining the medullary cavity–and give twigs to the adjoining canals.
Its upper third is rough, for the origin of the soleus; its lower part presents a triangular surface, connected to the tibia by a strong interosseous ligament; the intervening part of the surface is covered by the fibers of origin of the flexor hallucis longus. Near the middle of this surface is the nutrient foramen, which is directed downward.
[63]: 152 In some neotheropods, the distal section of the suture is not continuous but forms a fenestra, the pubic foramen, that is visible in ventral view. [63]: 141 The proximal part of the pubis features an opening, the obturator foramen, which is located close to the acetabulum and visible in lateral view. The obturator foramen allows for ...
The obturator internus originates on the pelvis on the obturator foramen and its membrane, passes through the lesser sciatic foramen, and is inserted on the trochanteric fossa of the femur. "Bent" over the lesser sciatic notch , which acts as a fulcrum, the muscle forms the strongest lateral rotators of the hip together with the gluteus maximus ...
The femur is the largest and thickest bone in the human body. It is considered the strongest bone by some measures, though other tests suggest the temporal bone may be stronger. On average, the femur length accounts for 26.74% of a person's height, [4] a ratio found in both men and women across most ethnic groups with minimal
