Blood is a connective tissue with a fluid matrix called plasma. Three basic types of cells are found suspended in plasma:The Erythrocytes (red blood cells) are pink with a light center (where the cell is thinner and the light shines through).onnective tissue fibers, blood vessels, and sweat glands can be seen embedded in the adipose tissue. As the photomicrograph illustrates this tissue consists of adipocytes that contain lipid droplets. Adipose Tissue: 1  Description: Resembles a chicken-wire fence.
It is possible that hypofunctional 5-HTP cells (reflecting TPH1 dysfunction) in the periphery, leading to deficient 5-HTP, low 5-HT, and concomitant compensatory TPH2 activation in the brain, may cause endogenous depression.
If the endogenous marijuana receptors are blocked 24-hours each day, day after day, we lose the ability to experience pleasure and become apathetic and depressed. Overall, the symptoms of the amotivational syndrome are very similar to the symptoms of depression.
