Other terms used include grave, extremely critical, critical but stable, serious but stable, guarded, [3] and satisfactory.. The American Hospital Association has advised doctors not to use the word "stable" either as a condition or in conjunction with another condition, especially one that is critical, as it inherently implies unpredictability and the instability of vital signs.

[20] [21] Puberty which starts earlier than usual is known as precocious puberty, and puberty which starts later than usual is known as delayed puberty. Notable among the morphologic changes in size, shape, composition, and functioning of the pubertal body, is the development of secondary sex characteristics , the "filling in" of the child's ...
As such, shock is a runaway condition of homeostatic failure, where the usual corrective mechanisms relating to oxygenation of the body no longer function in a stable way. When it occurs, immediate treatment is critical in order to return an individual's metabolism into a stable, self-correcting trajectory.
This means that with each successive subdivision, the ratio of nuclear to cytoplasmic material increases. [5] Initially, the dividing cells, called blastomeres (blastos Greek for sprout), are undifferentiated and aggregated into a sphere enclosed within the zona pellucida of the ovum. When eight blastomeres have formed, they start to compact. [6]
The vas deferens can grow back together after a vasectomy–thus resulting in vasectomy failure. [40] This occurs due to the fact that the epithelium of the vas deferens, similar to the epithelium of some other human body parts, is capable of regenerating and creating a new tube in the event that the vas deferens is damaged and/or severed. [41]
Human physiology is the study of how the human body's systems and functions work together to maintain a stable internal environment. It includes the study of the nervous, endocrine, cardiovascular, respiratory, digestive, and urinary systems, as well as cellular and exercise physiology.
