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.

Lacunar stroke or lacunar cerebral infarct (LACI) is the most common type of ischemic stroke, resulting from the occlusion of small penetrating arteries that provide blood to the brain's deep structures.
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]
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 chondrocyte in cartilage matrix has rounded or polygonal structure. The exception occurs at tissue boundaries, for example the articular surfaces of joints, in which chondrocytes may be flattened or discoid.
The roof of the fossa is especially dilated, forming a lacuna; medical instruments being inserted into the male urethra should initially be directed towards the floor of the fossa [1] so as not to get snagged at the fossa.
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 ]
