A Beautiful Mind
A Beautiful Mind
My responses to A Beautiful Mind varied greatly. Initially, I thought about how intelligent the main character must be. I felt sorry for John Nash, whose feelings of loneliness, sadness and depression prevailed as he struggled to find a focus for his project and a place in the student social hierarchy. I frequently wondered what his connections to home were; without them and with lack of family support, he became socially awkward. I was amused by his interactions with women. His bluntness in asking for sexual favors and his responses to their reactions was intriguing and disorganized.
I became happy for him when he developed a meaningful relationship with a woman. However, I continued to wonder about his absent family and their non-involvement in his wedding and his scholarly accomplishments. His star gazing and observations about star patterns was intriguing and again, a testament to his geniuS.
There are three distinct types of muscles: skeletal muscles, cardiac or heart muscles, and smooth muscles.
Skeletal muscle fibers have multiple nucleuses, with the cell’s nuclei located just beneath the plasma membrane. The cell composes striped myofibrils. In each myofibril there are protein filaments that are held down by tendons. The fiber is one long string-like thing. The smallest cross section (the one shaped like a cross) of skeletal muscle is called a sarcomere which is the main unit within a cell. It extends from the one Z line to the next attached Z line… kind of like a rope. The individual sarcomere has alternationg thick myosin and thin actin protein filaments (the things that help keep you strong).
When skeletal muscles are stimulated by action or movement, they contract by shortening and extending the sarcomeres. Actin and myosin fibers overlap and contract in motion towards and away from each other.
