Over evolutionary time organisms have diversified beyond imaginable. The earth is full of life from the simplest, single celled organisms, to whales the size of school buses. Even though there is a sundry of species alive on the planet today, even more species have lived in the past. In comparing the flying fish and the jerboa, one can see the changes that organisms have made overtime to better their chance of survival in their environment. By studying comparative anatomy, one can see the way…

An Arteriovenous Malformation (AVM) can be described simply as a tight rubber band ball of abnormal blood vessels with weak walls. These can be located anywhere in the body. Arteries carry blood containing oxygen from the heart to the brain. An AVM bypasses normal brain tissue and directs blood from the arteries to the veins without a capillary bed in between. Brain AVM’s occur in less than one percent of the population (per 100,000 people) and are more common in males than females. Being…

• Describe ossification in fetal development. During development, the fetal bones are made up of cartilaginous tissue, which is like osseous tissue, except it is more flexible. The absence of calcium salts in its intercellular spaces makes it less dense. As development continues, the process of the depositing of calcium salts into the cartilaginous tissue occurs, and continues throughout their life. Ossification is the gradual replacement of cartilage and its intercellular substance by bone…

is a narrow channel that folds and closes during the third and fourth weeks of pregnancy to form the brain and spinal cord. Encephalocele is a sac-like protrusion or projection of the brain and the membranes that cover it through an opening in the skull. Encephalocele happens when the neural tube does not close completely during pregnancy. The neural tube is a hollow, embryonic structure that gradually develops into the central nervous system, comprising of the brain and spinal cord. This in the…

In Chapter 5, page 139, where it begins with (“another example…”) and ends with (“shaken baby syndrome”) This Paragraph have a great interest to me because it talks about the “ shaken baby syndrome” and how people Shake their baby to stop them from crying.This is a common thing that's a lot of young parents do.

homologous morphological structure that can examine is the bones that make up the hoof and legs of horses with the arms of humans. Both horses and humans exhibit the presence of similar bones such as the humerus, radius, ulna, phalanges etc. The phalanges is what mostly makes up the hoof of a horse and finger of humans have a different function in each specie. For example, while humans use their phalanges for grabbing objects, horses uses them for walking. This common bone structure is present…

coming to give you a full body high five would explain much. That is except for the sharp pain that the prelude the bright light was from the back of the head and not the front. One problem when you regain consciousness after a blow to the back of your skull is the throbbing pain that wakes up along with you. Normally it does feel like a kissing cousin to a future amnestic night of club hopping when your gag reflex has been disabled and tequila is now the star of the show. As far as the wetness…

(TMJ Treatment/Teeth Grinding) TMJ Treatments In Salem, OR Your temporomandibular joint (TMJ) is the joint directly in front of your ears that connects your jaw to your skull. This very important joint is in charge of helping with talking, chewing, yawning, and other general jaw movements, both up and down and side to side. Sometimes your TMJ can develop problems in the joint itself or the muscles that are around the joint. These problems, which are somewhat common and can be extremely painful…

begin to lose other traits. Basically evolution is change. However, evolution is only seen as a reliable theory. Evidence that scientist have to prove evolution as a reliable theory are fossils and relative dating. In this lab report, I measured 11 skulls and based on the measurements, I will try to either prove if my hypothesis of the amount of organisms that bipedal is either correct or incorrect. Hypothesis: If over time the measurements decrease due to evolution…

left side of her skull twice when she was rushed into the emergency room. After radiographic images were taken and a skull series was performed it was evident that the patient had an open communited depressed fracture of the left temporal bone. Other radiological modalities were utilized in diagnosing the type and severity of her fracture. After diagnosis was made apparent then the appropriate treatment was provided to help Ms. Jenner on a road to recovery. Depressed Skull Fracture A 65…
