The lacuna are situated between the lamellae, and consist of a number of oblong spaces. In an ordinary microscopic section, viewed by transmitted light, they appear as fusiform opaque spots. Each lacuna is occupied during life by a branched cell, termed an osteocyte, bone-cell or bone-corpuscle.
The vascular lacuna (Latin: lacuna vasorum (retroinguinalis)) is the medial compartment beneath the inguinal ligament. [1] It is separated from the lateral muscular lacuna by the iliopectineal arch. [1] [2] It gives passage to the femoral vessels, [1] lymph vessels and lymph nodes. The lacunar ligament can be a site of entrapment for femoral ...

The muscular lacuna (Latin: lacuna musculorum) is the lateral compartment of the thigh beneath the inguinal ligament. It is separated from the medial vascular lacuna by the iliopectineal arch . It is occupied/traversed by the iliopsoas muscle , and femoral nerve . [ 1 ]
In cartilage, the lacunae and hence, the chondrocytes, are isolated from each other. Materials picked up by osteocytes adjacent to blood vessels are distributed throughout the bone matrix via the canaliculi. Diameter of canaliculi in human bone is approximately 200 to 900 nm. [1]
Lacunarity, from the Latin lacuna, meaning "gap" or "lake", is a specialized term in geometry referring to a measure of how patterns, especially fractals, fill space, where patterns having more or larger gaps generally have higher lacunarity. Beyond being an intuitive measure of gappiness, lacunarity can quantify additional features of patterns ...
In male anatomy, the lacuna magna (also called Guérin's sinus) is the largest of several recesses in the roof of the navicular fossa of the male urethra. Structure [ edit ]
The largest of these recesses is called lacuna magna (or the sinus of Guérin, or Guérin's sinus), which is situated on the upper surface of the fossa navicularis. Located deeper within the lacunae are branching mucous tubules called the glands of Littre. The lacunae of Morgagni are named after Italian anatomist Giovanni Battista Morgagni ...
