which contains the abdominal organs; and the pericardial cavity, which encloses theheart. The dorsal part of the mesoderm becomes separated from the ventral mesoderm and divides itself into serial parts like a row of blocks, 31 on each side. These mesodermal segments grow in all directions towar...
Since German anatomist Walter Spalteholz developed the first tissue clearing reagent over 100 years ago, systematic three-dimensional (3D) observation and analysis of whole organs and whole bodies have been continuously conducted in biomedical research, linking classical anatomy to modern systems biology1...
You will notice that every external anatomical structure on one side of the line has a counterpart on the other side. Yet you have only one heart, one liver, one stomach, one pancreas and one spleen, and your colon coils from your right to your left. Even those organs that come in ...
This protocol describes how to fix, embed, clear and stain excised organs or whole organisms to create optically transparent samples. This versatile protocol is able to process a wide range of sample types for high-resolution imaging. To facilitate fine-
The exocrine system consists of organs and glands that produce substances that are used outside the bloodstream, primarily for digestion. The pancreas is one such organ, although it secretes some chemicals into the blood and thus is also part of the endocrine system. Much has been learned about...
At slaughter, the internal tissues and organs were weighed. Loin and ham muscles were dissected from the carcass and trimmed of skin and external fat, and the ham was deboned. Residuals from the loin and ham were combined with the remaining carcass. Body components were ground, and their ...
brown fat, and beige fat. While white fat stores energy, brown fat helps burn calories. Beige fat tissue contains a mixture of the two. And white fat can also be broken down into two additional categories: the type under your skin is different from that which covers your internal organs....
Receptors in the respiratory muscles themselves also are very important: tendon organs that sense changes in tension, muscle spindles that sense changes in muscle length, and unmyelinated small afferent fibers that sense metabolic-inflammatory products. These somatic receptors provide information on the le...
From blood storms to honeycomb lungs, here’s an organ-by-organ look at how COVID-19 harms humans.
but also intriguingly of female reproductive organs in men as well as in women. This apparently paradoxical association in men may not be completely illogical, as female reproductive organs would be responsive to oestrogen-activated pathways and the formation of the Mullerian duct, from which the ut...
