Shawn Johnson Mrs Saltsburg Human Anatomy 4-07-2013 Skeletal Disorders Leukemia: The condition of leukemia is when your bone marrow starts making abnormal white blood cells. Some of the symptoms include fever‚ headaches‚ joint pain‚ swollen spleen‚ and losing weight. To be diagnosed with leukemia‚ your white blood cells would be a high level and all the other blood cell levels would be lower then normal. The treatment for leukemia is chemotherapy( which uses medicine to kill the cancerous cells

Professor: Pierre Louis‚ Vertulie 4/16/13 A&P SKELETAL PROJECT! This system has 206 bones and associated cartilage‚ tendons‚ and ligaments. Because bone is unbending‚ it gives the body a structure‚ maintains its shape‚ and protects essential organs. Bones provide a place for muscles and supporting structures to attach‚ and‚ with the movable joints. A joint is a place of union between two or more bones that may be movable or immovable. Bone also functions as a place for mineral storage

ACTIVITY 1: THE RESTING MEMBRANE POTENTIAL 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? When the diffusion is greater on one side‚ the other side will slow down. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? There are two potassium’s for every sodium so the increase of potassium will make it more
