Question 1. a) “What serosal cavities have been penetrated by the 1st arrow?” The pleural cavity and pericardial cavity have been penetrated by the 1st arrow as they tend to appear in the thoracic cavity on the left side of the chest. b) “Explain the location, the microscopic characteristics of the serous membrane, and the purpose of the serous membrane.” The serous membrane, the peritoneum is located within cavities of the abdomen and the pelvis. Pleura are found in the thoracic cavity…

study showed that more than 40% of retired NFL players had brain injury (https://www.aan.com/PressRoom/Home/PressRelease/1453). The study utilized MRI scans to detect the amount of white matter in each player’s brain. The white matter are myelinated axons that conduct action potentials, allowing one to learn and carry out their motor skills. According to a study by Sampaio-Baptista and colleagues, there is a correlation between white matter and learning rate.…

caring between the main characters while obviously showing that she is scared. His writing style is also very elaborate and uses a good amount of difficult vocabulary. “Ben could feel the nerves trying to placate their followers, the dendrites and axons sending prophetic messages of doom, ignored in the malaise of exorbitance.” (Tieryas 400) This descriptive vocabulary can give you a sense of depth within what’s…

One of the most sought out secrets is the one of how the mind works in terms of the different networks of neurons. In recent years neuroscientist have accomplished a lot with regards to what parts of the brain are active at certain times such as when you smile, when you see a picture, or when you have an enjoyable memory, but one thing that neuroscientist have not been able to discover is how one age mentally. Many theories have been proposed and seen through different studies. The most…

take place within the brain that allow us to speak, move, see, remember etc. Inside a healthy brain billions of neuron cells constantly communicate with one another. They receive messages from each other sending an electrical charge traveling down the axon. The electrical charges release chemical messengers called neurotransmitters Marieb and Hoehn (2016) study find “Examinations of brain tissue reveal senile plaques littering the brain like shrapnel between neurons. The plaques consist of…

Roessman, U. (1984) broadly define DAI as a distinct form of head injury induced by direct external force at the time of trauma and characterized by axonal swelling, hemorrhages or lacerations of the corpus callosum, and of the brain stem. Basically, the axons in the brain, which are key in sending and receiving signals, had been severely sheared off during the accident. A subdural hematomas is a bruise beneath the skull, which causes swelling and bleeding with nowhere to go for…

The patient was admitted into a small, rural hospital at 1900 for an ongoing complaint of unrelieved indigestion. The patient, 48 year old male has a history of and is presently involved with smoking. After admission into the hospital it is ruled out that the patient underwent a rule out myocardial infarction with further testing involving a cardiac catheterization to be done after admission upon a separate medical center. The patient also presents to the hospital with a history of a high-fat…

Neurons are not the only cells that occupied the central nervous system (CNS). In fact, neurons are outnumbered by supportive non-excitable cells, collectively called neuroglia (a.k.a. glia). The term glia was coined by Rudolph Virchow in 1859 to indicate the “connective tissue” surrounding the neurons (glia came from Greek meaning glue). However, the combination of the activities of glial cells and neurons is crucial for brain functions (Steward 2000). There are three types of glial cells in…

Attention-Deficit/Hyperactivity Disorder, otherwise known as ADHD, is a common neurobehavioral disorder that affects at least 10% of the children in United States (Bálint et al., 2009). Once thought by many that ADHD retrogrades or goes away as the child goes through puberty, but scientific researchers suggest differently. ADHD continues all the way into adulthood, if untreated the individual would have hard time coping in a social enviroment and develop to their full potential. (Fitzgerald &…

external anatomical structures that males and females have are; the male and female organs both are the common function, ovaries & testis both produce gametes & sex hormones, clitoris & glans of penis are both sexual simulants & contain nervous system axons, and the labia majora & scrotum both cover and protect reproductive structures. There are many ways that male and female anatomical structures are different. One example is that although both male and females produce gametes, only females…
