Histological observations of human embryos hitherto have been carried out using paraffin sections of 5 to 10 m thickness, stained with the H-E method or simply with carmine. The thinness of sections and clearness of staining reveal the histological details of this embryo very accurately.
Emphasis is particularly placed on the organization of subsections of the Golgi apparatus and the questions of how Golgi subsections may be related to functional subcompartments of the Golgi system.
Though more than 300 years have elapsed since the first description of the peculiar course of the spinal accessory (XI) nerve by Willis (1664), the crucial problems concerning what is known as accessory field of musculature and its innervation are still unsolved and a matter of controversy.
To exemplify this, he formulated a universal and purely formal law of growth in mathematical terms making the comment: "I now suggest that the body form follows immediately from germinal growth and can be derived from the given germinal form according to the laws of growth.
PowELL and KRUG ER, 1960}, GusEL'NIKov and SUPIN (1964) and KARA MYAN and BELEKJIOVA (1964) on various reptiles, and of PowELL and CowAN (1961), KARTEN and REVZIN (1966) and REVZIN and KARTEN (1967) on the pigeon.
After consideration of oligodendroglia, microglia and ependymal cells, we describe the development of Schwann cells, the glia found in the PNS.In general, morphological observations of developing mammalian nervous tissues (mostly rodent) are emphasized;
The prostate hosts neuroendocrine cells whose origin and functional roles warrant better understanding.
Rhythmic changes in physiology and behaviour within a 24 h period occur in living organisms on earth to meet the challenges associated with the daily changes in the external environment.
Articular cartilage is a highly specialized avascular connective tissue. This multidisciplinary article reviews the molecular and morphological aspects of GLUT expression and function in chondrocytes and their mesenchymal and embryonic stem cell precursors.
This book examines the expression and function of ss1-integrins in articular chondrocytes. The authors discuss their research and that of others involved in studying chondrocyte ECM adhesion and signal transduction.
In addition much attention has been paid to how nephron number may be altered by changes in the environment of the developing kidney and to the consequences for the remaining nephron gene expression and kidney function when total nephron number is altered.
How could a structure as complex as the vertebrate brain develop from the simplest multicellular animals? Natural selection offers an impeccable mechanism for the gradual transformation of species, but even Darwin sometimes expressed doubts about the origin of highly complex structures.
Neuregulin signals are also involved in the development diseases including breast cancer, heart disease and the pathogenesis of schizophrenia. This book reviews the biology of Neuregulins and their receptors and summarizes recent research, which has established crucial functions of this signaling system during development and disease.
The objective of the present work is to review the existing literature on joint incongruity, cellular mechano-transduction, and computer simulations of mechano-adaptive bone remodelling, and to quantitatively assess the effect of incongruity on load transmission and subchondral mineralisation.

This title allows the reader to study the most recent and accurate information about cardiac veins that is available. The photographic documentation is characterized by great accuracy, aestheticism and quality. The data obtained from human cadaveric specimens may be easily adapted and applied to benefit cardiological patients.
Advances in cell, developmental and molecular biology, and the discovery of regeneration-competent cells in many non-regenerating mammalian tissues, have given impetus to systematic investigations that will enable us to regenerate these tissues by cell transplantation or the pharmaceutical induction of regeneration from the body's own tissues.
The book is intended for professors and researchers in vascular biology, angiogenesis research and developmental biology. It furthermore offers an excellent basis for entry level researchers and newcomers to this field, as well as for teachers, graduate students, advanced science and medical students.
