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
foramen: hole, opening, or aperture, particularly in bone Latin forāmen: foramen magnum-form: used to form adjectives indicating "having the form of" Latin fōrma, form, shape cruciform, cuneiform, falciform fore-before or ahead Old English fōr(e)-, before, in front of foregut, foreshadow fossa: a hollow or depressed area; a trench or channel
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 ...
A foramen is any opening, particularly referring to those in bone. [14] Foramina inside the body of humans and other animals typically allow muscles, nerves, arteries, veins, or other structures to connect one part of the body with another. An example is the foramen magnum in occipital bone.
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.
Apical foramen, the opening at the tip of the root of a tooth; Foramen ovale (heart), an opening between the venous and arterial sides of the fetal heart; Foramen transversarium, one of a pair of openings in each cervical vertebra, in which the vertebral artery travels; Greater sciatic foramen, a major foramen of the pelvis
It is perforated at its inner part by a nutrient canal. Below it there is a smooth, rounded border, the arcuate line, which runs anterior, inferior, and medial. When the "left" or "right" adjective is used (e.g. "right iliac fossa"), the iliac fossa usually means one of the inguinal regions of the nine regions of the abdomen.
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
