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 ...
This constitutes the so-called capsule of the space. Each lacuna is generally occupied by a single cell, but during the division of the cells, it may contain two, four, or eight cells. Lacunae are found between narrow sheets of calcified matrix that are known as lamellae (/ l ə ˈ m ɛ l i / lə-MEL-ee).
This zone is called clear zone or sealing zone. The actin filaments enable the cell membrane surrounding the sealing zone to be anchored firmly to the bony wall of Howship's lacunae. In this way, a closed subosteoclastic compartment is created between the ruffled border and the bone that is undergoing resorption.
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.
The spaces the cell body of osteocytes occupy within the mineralized collagen type I matrix are known as lacunae, while the osteocyte cell processes occupy channels called canaliculi. The many processes of osteocytes reach out to meet osteoblasts, osteoclasts, bone lining cells, and other osteocytes probably for the purposes of communication ...
Receptors are located throughout the body including the skin, epithelia, internal organs, skeletal muscles, bones, and joints. The cutaneous receptors of the skin project in an orderly fashion to the spinal cord , and from there, via different afferent pathways ( dorsal column-medial lemniscus tract and spinothalamic tract ), to the ventral ...
Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision. Microscopic anatomy is the study of minute anatomical structures assisted with microscopes , and includes histology (the study of the organization of tissues), and cytology (the study of ...
The lacunar ligament is the part of the aponeurosis of the external oblique muscle that is reflected backward and laterally and is attached to the pectineal line of the pubis.
