The study of human anatomy reaches back thousands of years, to the Romans and Greeks. Herophilus, the Greek anatomist, is considered the first to take a scalpel to skin to see how our bodies work ...
In anatomy, a spatium or anatomic space is a space (cavity or gap). Anatomic spaces are often landmarks to find other important structures. When they fill with gases (such as air) or liquids (such as blood) in pathological ways, they can suffer conditions such as pneumothorax, edema, or pericardial effusion. Many anatomic spaces are potential ...
Interstitium. The interstitium is a contiguous fluid-filled space existing between a structural barrier, such as a cell membrane or the skin, and internal structures, such as organs, including muscles and the circulatory system. [1] [2] The fluid in this space is called interstitial fluid, comprises water and solutes, and drains into the lymph ...
Potential space. In anatomy, a potential space is a space between two adjacent structures that are normally pressed together (directly apposed). Many anatomic spaces are potential spaces, which means that they are potential rather than realized (with their realization being dynamic according to physiologic or pathophysiologic events).
A sarcomere is defined as the segment between two neighbouring Z-lines (or Z-discs). In electron micrographs of cross-striated muscle, the Z-line (from the German "zwischen" meaning between) appears in between the I-bands as a dark line that anchors the actin myofilaments. Surrounding the Z-line is the region of the I-band (for isotropic ).
Trapezoid. The structure of the trapezoid bone forms a firm, stationary joint with the second metacarpal base. The trapezoid is shaped like a wedge. The side of the bone that is closest to the ...
The retroperitoneal space ( retroperitoneum) is the anatomical space (sometimes a potential space) behind ( retro) the peritoneum. It has no specific delineating anatomical structures. Organs are retroperitoneal if they have peritoneum on their anterior side only. Structures that are not suspended by mesentery in the abdominal cavity and that ...
Scaphoid. The scaphoid is a carpal bone in the wrist. It sits on the radial or lateral side of the wrist near the thumb. It is the largest bone in the wrist’s proximal row. Lunate, triquetral ...
