Becker Muscular Dystrophy
==== Becker Muscular Dystrophy is one of the nine types of muscular dystrophy, its a inherited disorder that slowly worsens muscle weakness in the legs and pelvis.Its caused by your muscle cells not producing enough dystrophin (protein) and without enough of it the muscles cells become damaged and weaken over a slow period of time. This disorder was named after a German doctor (peter Emil Becker). This disorder is similar to Duchenne muscular dystrophy but the difference is that it gets worse at a slower rate an its less common. Becker Muscular dystrophy is an inherited disorder so having a family history of this raises the risks of you getting it but this disorder is mostly found in males. It happens in about 3 out of 6 of every 100 000 births. ==== Other symptoms maybe include breathing problems, cognitive problems, tiredness& loss of balance and coordination.
 * === Symptoms: ===
 * walking gets worse over time
 * frequent falls
 * difficulty running, hopping etc
 * loss of muscle mass
 * weakness in arms, neck

=Evolution of Snakes=

=
It is believed that snakes evolved from aquatic lizards, from fossil research experts believe that snakes had limbs when they lived in the water. They also say that they had external ears and eyelids just like lizards. Snakes now have transparent eyelids and lost of external ears due to evolution, these changes may have been to help avoid scratches of the cornea and avoid dirt getting into their ears when they are burrowed. Color of snakes also changed so that they can camouflage in their habitat.=====

This picture shows snakes in the past and now.

Fossils
Fossil records of snakes are very limited mostly because in terrestrial environments which means places lots of erosion and also because the skull,ribs,backbone and skeleton are very delicate so they quickly decay. One of the biggest fossils found was 49 ft long which is almost twice the size of snakes today, experts think that snakes have gotten smaller due to lack of food in their habitats and because they moved on land so they they didn't have to move as much. One of the most complete fossils was found in Argentina Also as many of you may know snakes can eat things way bigger then them for example us humans this is possible due to the evolution of their hinged jaws. Snake have evolved to have no limbs but according to nation geographic its possible for pythons to grow limbs back and it doesn't require a whole evolutionary cycle for it to happen they just need the right genetic mutation.

wiki post #3-Body systems January 20,2017 =Respiratory system: Asthma=

Asthma is a respiratory condition caused by spasms in the bronchi of the lungs which causes difficulty in breathing. Its a chronic disease that inflames and narrows airways.
difference between normal bronchial tubes and ones with asthma

Symptoms:

 * ====wheezing====
 * ====chest tightness====
 * ====shortness of breath====
 * ====coughing====

Some things that may trigger asthma are genes, infections, allergies, airborne conditions, medications,food, weather etc.
====Asthma is not curable but a very easy disease to manage due to inhalers and asthma clinics. At the asthma clinic you will take multiple breathing tests to see how your breathing is doing and to find which inhaler will work better for you and how bad your asthma is. Inhalers help by taking the medicine straight to you lungs and usually starts to kick in minutes after use.====

Asthma attacks
====Asthma attacks are rapid changes and worsening of symptoms,the lining of the airways becomes more swollen and thicker mucus is produced then normal. These attacks can become really serious and require medical help, without help you would eventually not be able to talk, lips lining ill get a bluish tint which means you have less oxygen in your blood and you could possibly die.====
