In cell biology, quiescence is the state of cell when it is not dividing. Cell biology (also called cellular biology or cytology, from the Greek kytos, container) is an academic discipline which studies cells. ... Cell division is the process of a biological cell (called a mother cell) dividing into two daughter cells. ...
Quiescence can also refer specifically to the "rest" state of a cell. Neurons, for example, are quiescent when not firing and sarcomeres (muscle cells) are quiescent when not contracting. Neurons (also spelled neurones or called nerve cells) are the primary cells of the nervous system. ... A sarcomere is the basic unit of a cross striated muscles myofibril. ... Structure of a skeletal muscle A muscle contraction (also known as a muscle twitch or simply twitch) occurs when a muscle cell (called a muscle fiber) shortens. ...
The quiescent input current I.sub.in flows from terminal 1 to terminal 2 and spreads over the two parallel-arranged circuits constituted by the transistors T.sub.1 and T.sub.2 through which a quiescent current I.sub.12 flows and constituted by the transistor T.sub.5 and the impedance R through which a quiescent current I.sub.r flows.
The quiescent output current I.sub.out is dependent on the value of R and the value of I.sub.in and the gain factors of the four transistors T.sub.1 to T.sub.4.
The transistor symmetry is maintained: the quiescent output current I.sub.out is insensitive to the values of the threshold voltages as long as transistors of the same conductivity type have the same threshold voltage, which is the case on an integrated circuit.
The solution, Dr. Wilmut discovered, was to, in effect, put the DNA from the adult cell to sleep, making it quiescent by depriving the adult cell of nutrients.
The conflict then settled into a quiescent phase for several years.
Quiescent derives from the present participle of Latin quiescere, to rest, from quies, rest.
