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 (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.
The femur is the largest and thickest bone in the human body. It is considered the strongest bone by some measures, though other studies 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
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 ...
It is coated with cartilage in the fresh state, except over an ovoid depression, the fovea capitis, which is situated a little below and behind the center of the femoral head, and gives attachment to the ligament of head of femur. The thickest region of the articular cartilage is at the centre of the femoral head, measuring up to 2.8 mm. [1]
Organisms in the dinosauria clade are defined by a perforate acetabulum, which can be thought of as a "hip-socket". The perforate acetabulum is a cup-shaped opening on each side of the pelvic girdle formed where the ischium, ilium, and pubis all meet, and into which the head of the femur inserts.
In anatomy and osteology, a foramen (/ f ə ˈ r eɪ m ən /; [1] [2] pl.: foramina, / f ə ˈ r æ m ɪ n ə / or foramens / f ə ˈ r eɪ m ən z /; from Latin ' an opening produced by boring ') is an opening or enclosed gap within the dense connective tissue (bones and deep fasciae) of extant and extinct amniote animals, typically to allow ...
[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 ...
