Angiotensin II is a potent that helps regulate blood pressure. Angiotensinogen, is an inactive hormone synthesized and released continuously from the . Its activation, which occurs within the , is initiated by the enzyme renin. Renin is released from the juxtaglomerular apparatus of the in response to either (1) blood pressure (as detected by decreased stretch of within granular cells, or by decreased NaCl detected by within macula densa cells); or (2) stimulation by the division. The sequential action of renin and angiotensin converting enzyme (ACE) causes the formation of angiotensin II (the active form of the hormone).

the dorsal column–medial lemniscus pathway (dcml) (also known as the posterior column-medial lemniscus pathway (pcml)) is a sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (position) from the skin and joints.

the cell is the smallest structural and functional unit of living organisms, which can exist on its own. therefore, it is sometimes called the building block of life. some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.
