  • University of Maryland, Baltimore Department of Physiology

  • The Department of Physiology at the University of Maryland School of Medicine has strong research traditions in cardiovascular-renal biology, neuroscience, and reproductive biology. Our graduate students, postdoctoral fellows, and faculty are working to unravel the mysteries of brain development, muscle contraction, cellular communication, hormone action, learning and memory, salt and water balance, and synaptic transmission. We offer both a PhD and a non-thesis Master's degree program.

  • specialty products for bioresearch

Harvard Apparatus is the worlds leader in developing and distributiing: syrinfe pumps, small animal ventilators, microincubators and perfusion systems for microspy, electroporation and sample preparation technologies: SPE, Dialysis, equilibrium dialysis.

  • Professor Patton's Anatomy & Physiology Site

  • Created by award-winning professor & textbook author Kevin Patton, this collection of Learning Outlines, Study Tips, Links, and more is the essential toolkit for the Human Physiology or A&P student! And there's some fun/goofy stuff there, too!

  • The Physiological Society

  • The Physiological Society is a learned society with approximately 2,500 members drawn from over 50 countries. The majority of members are engaged in research, in universities or industry, into how the body works. The Society's main aims are to promote the advancement of physiology and to facilitate communication, both between scientists and with other stakeholders. To achieve these objectives, the Society supports 4-5 meetings annually, publishes two journals and awards grants to allow members to travel and collaborate. Interaction with outside bodies is encouraged through representation on various councils and committees, and active membership of the Biosciences Federation.

  • The counterregulatory hormones - what are they all about?

  • A number of homeostats make use of pairs of counter-regulatory hormones to achieve very precise control of a variety of plasma constituents. The insulin/glucagon, the calcitonin/parathyroid hormone and the ADH/ANP (antidiuretic hormone/atrial natriuretic peptide) pairs are the best known examples. Counter-regulatory control, however, poses a number of theoretical problems. In the first place, the members of such pairs cannot be serving simply as backups for each other, for, if they were, diseases such as type 1 diabetes mellitus, and hypoparathyroidism would be very rare. The common occurrence of such diseases, caused by the loss of only one member of a counter-regulatory pair of hormones, suggests that homeostasis (of the blood glucose, or the plasma ionised calcium concentration, etc.) is dependent on the pair acting as a unit.

  • From the womb to the tomb

  • A journey through the human life cycle from fertilization till old age and death

  • Countercurrent mechanisms in physiology

  • Countercurrent mechanisms can isolate local environments in the body while still being perfused with blood. Energy consuming countercurrent mechanisms can be harnessed to create localised environments that differ markedly from the prevailing interior environment.

  • Are the fat soluble hormones hormones?

  • The fat soluble hormones, such as thyroxine, the sex hormones and cortisone (as well as aldosterone, and vitamin D) have physiological characteristics at variance with the concept that they act as messengers. Their physiology differs markedly from the water soluble hormoes such as insulin, glucagon, PTH, ADH, ANP etc. Lumping the fat soluble hormones together with the water soluble hormones is the cause a great deal of confusion and misconceptions about these fascinating substances.

  • Junk food and empty words

  • A critical, scientific examination of the term "junk food" and the meaning of "empty calories".

  • Kidney physiology in a nutshell

  • Kidney physiology made to make sense

  • What is life?

  • What characterizes life? An enquiry into how life influences a planet's chemistry; and what characterizes life processes

  • The lungs: our protection against the ravages of fresh air

  • The lungs are bags containing an atmosphere that has not exsisted on earth for 500 million years or more. It is against this fossil atmosphere, and not the modern atmosphere, that we dialyse our blood. Modern air is poisonous: its oxygen content is disastrously high, and contains virtually no carbon dioxide. Protecting ourselves against the ravages of modern fresh air is achieved on the one hand by having dead-end lungs connected to the atmosphere by a long narrow tube; and, on the other hand, maintaining significant ventilation perfusion "deficiencies" in different regions of the lungs.

  • What is normal?

  • How do we determine what is normal in physiology and the health sciences?

  • Physiology Society of Southern Africa

  • Affiliated to the IUPS, this society strives to to promote all aspects related to the TEACHING, RESEARCH AND EMPLOYMENT IN BASIC AND APPLIED HUMAN AND ANIMAL PHYSIOLOGY. By providing a spectrum of physiological information, the society strives to play a role in the progress of the physiological sciences in Southern Africa. promote
