Anatomical terminology is used to describe microanatomical (or histological) structures. This helps describe precisely the structure, layout and position of an object, and minimises ambiguity. An internationally accepted lexicon is Terminologia Histologica.
Histologic specimen being placed on the stage of an optical microscope. Human lung tissue stained with hematoxylin and eosin as seen under a microscope.. Histology, [help 1] also known as microscopic anatomy or microanatomy, [1] is the branch of biology that studies the microscopic anatomy of biological tissues.
Movat's stain is a pentachrome stain originally developed by Henry Zoltan Movat (1923–1995), a Hungarian-Canadian Pathologist in Toronto [1] in 1955 to highlight the various constituents of connective tissue, especially cardiovascular tissue, by five colors in a single stained slide. [2]
However, recent microanatomical and histological analysis of tetrapod fossil specimens found that early tetrapods like Acanthostega were fully aquatic, suggesting that adaptation to land happened later. [58] Research by Per Ahlberg and colleagues suggest that tides could have been a driving force for the evolution of tetrapods.
The mid-fusiform sulcus is a shallow sulcus that divides the fusiform gyrus into lateral and medial partitions. [1] [2] Functionally, the MFS divides both large-scale functional maps and identifies fine-scale functional regions such as the anterior portion of the fusiform face area.
Placoderms (from Greek πλάξ (plax, plakos) 'plate' and δέρμα (derma) 'skin') [1] are vertebrate animals of the class Placodermi, an extinct group of prehistoric fish known from Paleozoic fossils during the Silurian and the Devonian periods.
Neurilemma (also known as neurolemma, sheath of Schwann, or Schwann's sheath) [1] is the outermost nucleated cytoplasmic layer of Schwann cells (also called neurilemmocytes) that surrounds the axon of the neuron.
Among studies that use microanatomical methods, there is no reported evidence that human beings have active sensory neurons like those in other animals' working vomeronasal systems. [36] [37] Furthermore, no evidence suggests there are nerve and axon connections between any existing sensory receptor cells in the adult human VNO and the brain. [38]
