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

Frog Embryology The Egg The frog egg is a huge cell; its volume is over 1.6 million times larger than a normal frog cell. During embryonic development‚ the egg will be converted into a tadpole containing millions of cells but containing the same amount of organic matter. * The upper hemisphere of the egg — the animal pole — is dark. * The lower hemisphere — the vegetal pole — is light. * When deposited in the water and ready for fertilization‚ the haploid egg is at metaphase of meiosis

Question 1 Skeletal System The skeletal system is a strong yet light‚ flexible living framework that supports the body‚ protects delicate internal organs and makes movement possible. In addition‚ our bones store minerals while red bone marrow produces blood cells. Support The skeleton provides a frame that shapes the body and holds it up. Within the skeleton different characteristics of support can be identified. As the body’s main axis‚ the backbone provides support to the trunk with its upper

Lab 6: Amphibian Muscle Contraction Results: For this experiment‚ Isometric contractions of the gastrocnemius muscle of a frog were analyzed and from this data the latent period‚ twitch‚ motor unit summation‚ tetanus‚ fatigue & mechanical summation were measured. The data was used to quantify the effect of passive tension on the twitch force‚ effect of stimulus intensity on the twitch force‚ effect of stimulus frequency on contractile force of xenopus gastrocnemius muscle. The threshold voltage

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

This particular movie that she is in‚ Erin Brockovich‚ is when Julia Roberts was in her prime Erin has been divorced twice and is a gorgeous mother of three in her thirties. Erin starts out jobless and in a very messy court case the resulted from an unclear car accident. The accident put her $17‚000 in debt due to her

1. Explain the relationship between the skeletal and muscular systems. The relationship between the skeletal and muscular systems is that we are made up of bones all throughout our body and we need this to stand and hold our body together‚ similar to the skeletal system the muscular system is made up of soft tissue and is lined all over our body. We could not stand without the system as well. 2. Why is the circulatory system important? This system is important because it is used to circulate blood
