Oxygen uptake

What maximum oxygen uptake value would you expect from a elite male cross country skier?

This job lists the various steps involved in excitation of a muscle fiber.

Carpals: Bones of the wrist

I nned to know all the wrist carpals, and a fun and easy way to remember the carpals of the human wrist. Please also inclue a picture.

Kidney regulation of osmolarity and absorption of Na and water

Why is the distal tubule/collecting duct the only place to regulate osmolarity, seeing as we can absorb Na without H20 in the ascending loop? Is it just because the effect of any change in osmolarity earlier in the tubule gets undone (by ADH) in the distal tubule? Or is it because those earlier Na transporters aren't under physi

Physiology of ascitis

It is known that in ascites, liver damage usually causes a reduced osmotic pressure, and this results in edema. How does this increase the portal venous pressure?

Advanced Physiology

For 1) - 2) Responses should be 1 or 2 paragraph clear explanations? 1) Is there a correlation between the frequency of action potentials in a single muscle fiber and the tension it can develop? 2) Describe the 4 types of chromophores in the retina? 3) For 3a - 3j answer True/False; and offer brief eplanation to suppo

Advanced: Physiology

Give 1-2 paragraph or more detailed explanation for each: 1. When an adult athlete trains strenulously at high altitudes (eg. in the Rocky Mountains for a period of months, he/she is likely to experience an increase in the concentration of oxygen carying cells in the blood, which is an example of physiological acclimatizatio

Advanced Physiology

Give detailed paragraph or more explanation to all questions: 1) A fat cell responds to the presence of the harmone epinephrine by increasing cytosolic cyclic AMP Production, which leads to the catabolism of both glycogen and fat; what is the best explanation for this phenomenon? 2) After spending several days at a high altitu

Understanding the functions of various muscles.

1. Would latissimus dorsi or teres major be the stronger extensor and adductor muscle? Explain. 2. Would adductor longus or brevis be the stronger hip adductor muscle? Explain. 3. Why are the hip abductor muscles so important during single limb stance? What are the major hip abductor muscles?

The Nervous System: Sympathetic and Parasympathetic Responses

Provide a detailed description of the Autonomic Nervous system and where does it fit within the nervous system subdivisions. Include detailed description of the sympathetic and parasympathetic responses, their affect on target organs and anatomy of their neurons.

Physiological measurements

The attachments listed indicate what is required. However, I want you to look at the results given and indicate on the subject's aerobic effieciency, and work out his level of fitness given the index formula

Identifying the type of hemolysis on a blood agar plate. Attachments in Word.

Identify the type of hemolysis on a blood agar plate. This is a diagram of a Blood Agar Plate. On it are 3 gray bacterial colonies. The agar is red. The background is white. There are zones of hemolysis around 2 of the colonies. Which hemolysis does A, B and C have? Refer to the attachment below for the diagram.

G-Protein signalling events

How would you expect a non-hydrolyzable GTP analogue to affect signalling events that take place following exposure of a cell expressing α2-adrenergic receptors to: 1) α-agonists 2) β-agonists 3) α-antagonists 4) All of the above in the prescence of pertussis toxin or cholera toxin?
