A muscle contraction begins with a signal from a neurotransmitter from the nervous system. The signal innervates individual muscle fibers and sodium ions are released, depolarizing the entire fiber membrane and its tubules. Once the membrane has been depolarized, calcium ions are released from storage in the sarcoplasmic reticulum. The …
My project goes in more depth the stages of Mitosis. This is important because it is how our cells properly divide for every cell from skin cell to neuron cell within the body. The cell cycle is comprised of three parts interphase, mitosis, and cytokinesis. According to chapter three of …
For the STEAM Project, I talked about Rickets Disease in children, focusing around the skeletal system and how their bones are often deformed in different ways. I drew a normal skeleton and what the skeleton of a child with rickets would look like. As well as comparing it to things …
The rabies virus is very sneaky. From the start, the virus travels along the neural pathway into the central nervous system. The virus will infect the muscle cells closest to the site of infection. This is where they can replicate without being “seen” by the infected immune system. They replicate, …
My STEAM project will focus on describing the knee structure. I drew this anatomical diagram of the knee joint so that I have a deeper understanding and memory of it. We consider the knee joint is a modified hinged joint because it has the ability to rotate in addition to …
The renal system works as a gold mine in our body; it filters out the needed substances and disposes the waste. It is vital for the fabrication of many hormones, regulating fluids, and removing waste. Mining allows for the collection of minerals and the removal of waste. Both mining and the renal system contain operations that are comparable. (My essay makes the words in parentheses make more sense, they don’t relate directly to the kidneys. I also have other photos but I couldn’t upload them)
My project for STEAM has to do with traumatic brain injuries. I chose to create a blog post adding my artwork to illustrate how injuries to the head can affect an individual. This blog post is an overview of the different types of damages an individual may encounter, whether mild, …
According to information from the National Institutes on Drug Abuse and the American Society of Addiction Medicine, opioid overdose deaths significantly increased during the COVID-19 pandemic (Mann). Over 90,000 Americans died of opioid-related overdose in a 12-month period ending in September of 2020 (Mann). While these deaths are tragic enough, …
How does food poisoning affect the digestive and immune system? Bacteria is often the most common cause of food poisoning. One of the most common forms of food poisoning is salmonella because it can survive the harsh environment of the stomach and affects the body in many different ways, …
