INTRO TO PHYSIOLOGY I. Physiology – the science (study) of body function a. Uses biochemistry‚ cell biology‚ genetics‚ chemistry and physics b. Can be applied to study the cell‚ organ‚ system‚ or organism (whole-body) II. Cell – smallest living unit c. Can individually carry out it’s own basic life processes d. Specialized functions make their working together important to whole body operation III. Major tissue types (tissue = group of similar functioning

Neurophysiology of Nerve Impulses ACTIVITY 1 The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative

LAB ONE: Exercise 4 – Endocrine System Activity 1: Metabolism and Thyroid Hormone Part 1: 1. The normal rat had the fastest basal metabolic rate. 2. The metabolic rates differed between the normal rat and the surgically altered rats because the surgically altered rats didn’t have a thyroid or pituitary gland and therefore‚ the normal rat had a faster basal metabolic rate. The results turned out to be the way I predicted them to be. 3. T3 and T4 would be missing in the animal’s blood

Anatomy and Physiology Introduction In this assignment i will carry full investigation and analysis on the Skeletal system‚using my class notes‚researching on the internet and reading books. The Skeletal system is the system of bones‚ associated cartilages and joints of human body. Together these structures form the human skeleton. Skeleton can be defined as the hard framework of human body around which the entire body is built. Almost all the hard parts of human body are components of human

isolated frog muscle could be made to contract when the sciatic nerve was irritated with a metal object‚ conducted the first muscle experiments between 1661 and 1665. Later‚ between 1737-1798 Luigi Galvani determined that frog muscle responded to electrical currents. The kymograph‚ which was invented in the late 1840’s lead to the revolution of experimental physiology because it enabled muscle contractions to be analyzed and recorded. The muscle cell or fiber is the basic unit of a muscle. The frog gastrocnemius

example of systems working together is the skeletal system and the muscular system. Muscles are attached to bones; the muscles make the bones move. Without bones there is nothing to hold together the structure of muscles. Without both of these systems working together our body would be impossible to move on its own. The skeletal system is the system in our body that provides protection of the vital organs and support for the muscles and skin. The skeletal system is the most important system in the

A football player kicking a football is an example of a gross muscular skeletal muscle coordinating together to display the live-action potential of the chemistry between the functions of the nervous‚ muscular‚ and the skeletal system. For these actions to take place‚ the skeletal system must first be established and erected along with the cartilage‚ ligaments‚ and tendons attaching bones‚ muscle to bones‚ and articulation for movements.
