Following a surge of luteinizing hormone (LH), an oocyte (immature egg cell) will be released into the uterine tube, where it will then be available to be fertilized by a male’s sperm. Ovulation marks the end of the follicular phase of the ovarian cycle and the start of the luteal ph...
As an early pioneer of the microscope, Robert Hooke coined the term ‘cell’ in the 1600s to describe structures observed under magnification in plant material; ~ 400 years later, the word and the concept has stuck, achieving primacy as a fundamental unit of life on Earth. Unicellular o...

Classical studies suggest that the reptilian main cortical cell layer (layer 2) corresponds to the deep, output layers of mammalian neocortex, whereas its layer 1 is equivalent to mammalian layer I. According to this view, mammalian cortical evolution would have included the incorporation of new, ...
cell reproduction and cosmos movement, while questioning mankind’s current pursuit of “immortality” by technical means. In the exhibition’s preface, curator Miriam Sun touches on the significance of the cross-over exhibition: “By referring to Martin Heidegger’s arguments, we hope to return to...
Of special interest may be mentioned the chapters on cell contents, secretory organs, and anatomy in relation to habitat, as well as the final chapter on heredity and evolution. The book will form a very useful addition to the introductory text-books on structural botany.. 1921 Nature ...
(Humoral regulation) Endocrine action: the hormone is distributed in blood and binds to distant target cells Paracrine action: the hormone acts locally by diffusing from its source to target cells in the neighborhood Autocrine action: the hormone acts on the same cell that produced it Vasopressin ...
structure and function of the cell; the key components. In 1855, Rudolf Virchow discovered that new cells can arise from pre-existing cells through cell division. Cell division is the process that creates new cells, making reproduction of life possible, as well as the repair and growth of ...
