An Introduction to the Alexander Technique. The Alexander Technique is a psychophysical learning process using conscious thinking to restore coordination and/or prevent mis-coordination in human functioning. What F.M. Alexander (1869-1955) observed empirically, is that the relationship between head and spine in movement is a key factor in vertebrate coordinationâa fact that has subsequently been verified scientifically.
A glomerulus and its surrounding Bowman's capsule constitute a renal corpuscle, the basic filtration unit of the kidney.
Each nephron is composed of an initial filtering component and a tubule specialized for reabsorption and secretion. Composed of a glomerulus and Bowman's capsule, the renal corpuscle is the beginning of the nephron.ach kidney has over one million nephrons that are responsible for removing waste products from blood and maintaining water, salt and pH balance in the body. This vital job results in the formation of urine. 1.Afferent Arteriole The afferent arteriole receives blood rich in oxygen from the renal artery.
