The Human Body: Membrane or Resting Potential of a Cell
http://onlinehumanbody.blogspot.com/2010/10/membrane-or-resting-potential-of-cell.html
Понедельник, 18 октября 2010 г. Membrane or Resting Potential of a Cell. Because the ions are distributed unevenly between the intracellular and extracellular spaces, a potential difference, known as the membrane potential, is created at the cell membrane. This creates a negative charge in the interior of the cell relative to the extracellular space, the so-called resting potential. This potential difference can be measured with sensitive instruments and is about 60−80mV. Отправить по электронной почте.

The Human Body: Reduction or Maturation Division (Meiosis)
http://onlinehumanbody.blogspot.com/2010/10/reduction-or-maturation-division.html
Пятница, 8 октября 2010 г. Reduction or Maturation Division (Meiosis). Reduction or maturation division (meiosis) is a special form of cell division. In preparation for later fertilization, the male and female germ cells must halve their set of chromosomes (to form a haploid set), so that when ovum and sperm join, a normal double (diploid) set of chromosomes is formed. This process is known as meiosis, a cell division that comprises two steps: first and second maturation divisions. Biology of the Cell.

The Human Body: Cell Division (Mitosis)
http://onlinehumanbody.blogspot.com/2010/10/cell-division-mitosis.html
Суббота, 2 октября 2010 г. Mitotic cell divisions permit a fertilized ovum to develop into an organism. They are the preconditions for physiological renewal of cells and lead to regeneration of tissues after injury. With the exception of a fewcells (nerve cells, and cardiac and skeletal muscle cells), the ability to divide is maintained throughout the life cycle, though it varies among cells. As a rule, mitoses are less common in highly differentiated tissues. Отправить по электронной почте.

The Human Body: Endocytosis and Exocytosis
http://onlinehumanbody.blogspot.com/2010/10/endocytosis-and-exocytosis.html
Среда, 27 октября 2010 г. In exocytosis, products synthesized in the cell are enclosed in membranous vesicles and, by coalescence of these vesicles with the inside of the plasma membrane, reach the extracellular space. In this way, the transmitter substances in the endings of nerve cell processes are liberated at the synapses. The secretory products of most glandular cells leave the cell interior in similar fashion. Endocytosis and exocytosis are dependent on the action of ATP. Написать об этом в блоге.

The Human Body: Composition of the Extracellular Fluid
http://onlinehumanbody.blogspot.com/2010/10/composition-of-extracellular-fluid.html
Пятница, 15 октября 2010 г. Composition of the Extracellular Fluid. Bicarbonate (HCO3 −) and negatively charged proteins. The three compartments of the extracellular space—the interstitial fluid, the blood plasma, and the lymph—differ mainly in the amount of protein dissolved in each. For instance, the walls of the blood and lymph capillaries are permeable only to small ions and smaller organic particles, while large proteins are retained within the lumina of these vessels.
