The CRA originates from the ophthalmic artery, which is the first branch of the internal carotid artery and supplies together with its branches blood to the inner retina including the macula and fovea. Branch r
Local hemodynamic forces control the development, structure, and function of blood vessels;1 therefore, it is not surprising that these forces have been implicated in the pathogenesis of vascular disorders. Two of these disorders, atherosclerosis and bypass graft occlusion, give rise to focal prolifera...
The man had been brought to the ER where doctors found a small wound on his chest that didn’t look like much. But the victim died, and the coroner ordered an autopsy. The seemingly minor external wound told a far different story as Dr. Susan Maines of the Office of the State Medical...
7 The spectral waveform of the testicular artery, and its intratesticular branches, characteristically has a low-resistance, high-flow pattern, with a mean RI of 0.62 (range: 0.48 to 0.075)10,11,17,28 (Fig. 19-20A). The normal spectral waveform of the epididymal artery is similar to ...
The heart of each neuron is called the soma - a single thin cable-like fiber known as the axon that sticks out of the soma carries nerve signals away from the neuron, while many shorter branches called dendrites that project from the other end of the soma carry nerve signals to the ...
14 The LES can also be distinguished from the esophageal body, by the presence of more numerous intermuscular spaces containing blood vessels and connective tissue. Mitochondria and the smooth endoplasmic reticulum mass are greater in the LES than in the esophageal body.15 Lower Esophageal Tone and...
livers, such as the human liver. A similar conclusion can be reached for the portal veins: branch #1 of the right portal vein supplies the right dorsolateral region and branches #2 and #3 the right ventromedial region (Fig.6C–F). The numerous portal branches of the umbilical vein branch ...
There are numerous cell types including skin epithelial cells, immune cells, within the smooth muscle of blood vessels that use acetylcholine signalling to mediate cell shape change and physiological response to various signals [70–72]. This type of signalling is independent of the formation of ...
It contains myofibers, an aponeurosis, vessels, nerves, adenoid tissue, and mucous glands. Its lower border is free. The lower portion is termed the palatine velum. 10. The cribriform plate contains numerous tiny orifices for sensory fibers to the olfactory bulbs. 11. The vomer participates in...
When these nuclei divide, a septum will form at a right angle across each mitotic spindle, creating three hyphal compartments; without the clamp connection, only one of the three compartments would be likely to contain nuclei of both mating types. Clamp connections are lateral branches that ...
