a.Any of various organs or cell groups, such as the adrenal glands and the salivary glands, that are of endothelial origin and secrete a substance that is used or excreted by the body. b.Any of various organs, such as lymph nodes, that resemble true glands but perform a nonsecretory fun...
Afterwards, the function of the placenta changes into a tissue that serves the exchange of substances between mother and child fulfilling functions of the lungs, liver, kidneys, intestines and hormone-producing endocrine glands. The placenta is not only to be understood as a semipermeable membrane ...
This mucus forms a physical barrier, and its bicarbonate ions neutralize acid. Second, the epithelial cells of the stomach’s mucosa meet at tight junctions, which block gastric juice from penetrating the underlying tissue layers. Finally, stem cells located where gastric glands join the gastric ...
which is made up of epithelial cells and pigmented melanocytes, and the bottom dermis, which comprises a layer of connective tissue that holds blood

However, the small size of the fly limits the use of conventional implantable devices, representing an important challenge to uncovering general principles for motor control through the investigation of the experimentally tractable VNC—a nervous tissue that is coarsely organized like the mammalian spinal...
Next, if you notice a visible opening sore in your mouth, it could be a sign of a tooth abscess that should not be ignored. An abscess occurs when there is an infection deep within the tooth or in the surrounding gum tissue. As the abscess progresses, it can cause swelling and inflamma...
“over”) andhypodermis(hypo– = “below”). It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that compose an interconnected mesh of elastin and collagenous fibers, produced by ...
Endocrine: The endocrine system consists of a network of glands that secrete hormones — long-range chemical messengers that regulate how cells and tissue function — into the blood. These hormones, in turn, travel to different tissues and regulate many bodily functions, such as metabolism, growth...
The terminal domains are essential for storage of spidroins in the silk glands and fiber formation in the spinning duct, since it is here that they trigger crucial steps in the complex assembly of the spidroins upon environmental changes, like pH or ionic composition and strength18, 19. ...
