Anthropocentricity and pragmatism seem to be the main reasons why pigeons have served as the "black boxes" of so many psychologists and neurobehaviorists during the past decade. Anthropocentricity, because at first glance pigeons show several strik- ing features which bear a beautiful similarity to human systems in respects such as drinking, bipedality, territoriality, and apparently easy pursual of individual interests. Pragmatism, because of the suspected lesser complexity of the pigeon's system, which enables them to serve as good paradigms for human systems. For example, the visually...

The aim of this investigation is threefold: (a) to determine the time of origin of neurons of the rat cranial nerve ganglia; (b) to reexamine the embryonic development of the cranial nerve ganglia in the light ofthese dating results; and (c) to attempt to relate the chronology of these peripheral events to developmental events in those nuclei of the medulla that are intimately associated with the cranial nerve ganglia. Although thymidine-radiography has been used for over 2 decades to investigate the time of origin of neurons, most of these studies dealt with central nervous struc- tures....

The elucidation of the ultrastructure, cytochemistry and reactivity of cutaneous recep- tors is of particular importance in the unsolved biological problem of sensory transduc- tion. Topographically and with regard to evolution, cutaneous receptors are the most widespread primary sense organs. Because of their simple structure they are particular- ly useful in the study of the functional morphology of receptor end-organs. Research into receptor structures in classic neuromorphology revealed magnificent patterns and pictures of receptors, showing their great diversity and their presence in all...

The octapeptide angiotensin II (ANG II, Fig. 1) is the key effector substance of the renin-angiotensin system (RAS) (Werning 1972, Page and Bumpus 1974, Hierholzer 1977, Vecsei et al. 1978, Johnson and Anderson 1980 lit. ). ANG II is formed in two enzymatic steps. Renin acts on renin substrate, a glycoprotein, to produce angiotensin I (ANG I, a decapeptide), which in turn is acted upon by converting enzyme to form ANG II (Skeggs et al. 1968, Fig. 1). Renin substrate (angiotensinogen) is produced mainly in the liver (Page et al. 1941) and is a constituent of the ~-globulin fraction in the...

Dr. Tilly Edinger's first published paper dealt with a brain cast-in more exact terms an endocast of the cranial cavity-of Noth08auru8, a Triassic relative of the plesiosaurs. With this she embarked on a working lifetime of devotion to paleoneurology, a field of study that she was to transform. A daughter of the famous neurologist Ludwig Edinger, it was appropriate as well as fortunate that her early interest in fossil vertebrates should have become focused upon the recovery of such information concerning the history of the central nervous system as could be obtained from fossil material. Her...

In 1949, the Dutch anatomist Jan Boeke was able to write: "The socalled interstitial cells ...which lie at the end of the sympathetic endformation as a connecting link between the nervous endformation and the effector cells, are ...shown to be of pri- mary importance for the transferring and the remoulding of the nervous stimulus ..." And: " ...the problem of the interstitial cells and of the synapse is the most impor- tant problem of neurohistology of the future. " When Boeke wrote this, he advocated the generalized concept, holding that inter- stitial cells were intercalated between...

Considering the placenta from the functional point of view as an exchange organ be- tween mother and foetus, it is noteworthy that placentas of all types have a common structural principle in that all placentas have structures enlarging the surface area avail- able for exchange, as is also the case with other organs with similar functions, such as the lungs, kidneys and intestine. It may therefore be assumed that a quantitative rela- tionship must exist between the structure of the placenta and its function. Accurate information on this relationship could contribute to better understanding of...

Muscle is the only tissue of the four basic types that make the body that can be completely ablated while allowing fetal survival. This book is a result of 25 years of research employing engineered mouse fetuses with no skeletal muscle, a model system that provides a unique opportunity to study body development holistically.
A systematic anatomical analysis of such fetuses have shown that several anatomical locations are affected by the absence of the skeletal muscle. This book contains a summarized description of affected anatomical locations such as the alveolar lung epithelium,...

This new volume of the book series Advances in Anatomy, Embryology and Cell Biology provides a complete and exhaustive overview of the morphofunctional organization of the mammalian carotid body, a polymodal chemosensory organ responsible for the maintenance of blood gas homeostasis.
The authors review the state of the art of the neurochemical anatomy of carotid body´s cell populations with a special reference to their structural and neurochemical plasticity. The essential role of this organ in the generation, progression and maintenance of cardiorespiratory and metabolic...
