Sci-Fi Story Proposal: Transmissions from the Nearest Star
By 2022, the limit of humanity has surpassed the boundaries of its Solar System; unprecedented technology has allowed the spaceship SSE Invictus and its brave crew of six strong to begin to explore the Milky Way Galaxy. They know that it won’t be an easy journey, and they know that it won’t be a short one, but it will be worth it— for science, and for the glory of mankind. As time passes, however, the crew of the SSE Invictus start to become aware of how the trip is changing them; not just mentally, but physically as well, like space itself is feeding off them (which is illogical, all things considered: it’s really the effects of microgravity on their physiology, since their bodies have evolved to thrive in Earth’s gravity). They’re too far gone into space for the SSE Invictus to be recalled to prevent permanent damage, so at the end of it all, however, they will have to ask themselves: are they willing to burn their eyes for this mission?

These organs are used to support the body in the constant pressure of Earth’s gravity, but due to the microgravity conditions in space make these structural organs almost useless. The weightless environment also causes poor posture on the part of astronauts, and standing straight takes considerable effort (Mann, 2012). NASA has found out, in an evidence report published in 2015, that this is an atrophic response on the part of the muscles, to adapt to the reduced gravity. Skeletal muscle attrition was also common in the expeditions they studied, and several MRI results even confirmed that the atrophy continues during longer exposures to
Every day we use our skeletal muscle to do simple task and without skeletal muscles, we will not be able to do anything. Szent-Gyorgyi (2011) muscle tissue contraction in rabbit’s muscles and discovered that ATP is a source for muscle contraction and not ADP. He proposed a mechanism to cellular respiration and was later used by Sir Hans Krebs to investigate the steps to glucose catabolism to make ATP. In this paper, I will be discussing the structure of muscle fibers and skeletal muscles, muscle contraction, biomechanics, and how glucose and fat are metabolized in the skeletal muscles.
The three functions of the skeletal system are to support, to allow movement, and to protect. The skeleton is the framework of the body and also cradles its soft organs, with it the body would be just a jelly mass it wouldn’t have no definite shape and would just collapse. It supports the softer tissues and provides points of attachment for more skeletal muscles to hold all of the parts of the body upright. For example, the bones of the legs as pillars to support the body trunk we stand up. It also supports the body against the pull of gravity. The skeletal allows movement. The skeletal muscle attached to the bones by tendons and uses the bones as a simple mechanical lever system to move the body and its parts. All together with the muscles

The musculoskeletal system offers support and stability for your body so we can properly function and move around. Different types of muscle within the muscular system include cardiac, skeletal, and smooth. The reason our bodies are capable of producing movement is because of the way our muscles contract. Our adult skeletal structure is made up of 206 bones that all differ in shapes and sizes. The composing parts that make up the system include the bones, joints, and muscles that all connect so we’re capable of moving. These components allow for our bodies to maintain a stable structure that can keep us upright. The axial skeleton refers to the skull, the vertebral column which supports the spinal cord, ribs, and sternum. It offers protections
The remarkable strength of the bones in this system provides protection for the vulnerable organs in the body.
Sarcopenia is considered to be the degenerative loss of skeletal muscle mass and it’s functioning due to aging (Waters, Baumgartner & Garry 2000). It is linked to muscle atrophy which is shortening of the muscle. It can be mostly noticed in fast twitch fibres which usually fatigue easily and provide a larger amount of force in comparison to slow twitch fibres. Sarcopenia is usually ...
In Bright Star, Keats utilises a mixture of the Shakespearean and Petrarchan sonnet forms to vividly portray his thoughts on the conflict between his longing to be immortal like the steadfast star, and his longing to be together with his love. The contrast between the loneliness of forever and the intenseness of the temporary are presented in the rich natural imagery and sensuous descriptions of his true wishes with Fanny Brawne.

Outer space has always intrigued the human mind. Ever since humans inhabited the Earth, they have always looked to the heavens. Ptolemy, who lived over two thousand years ago, dreamed of being with the stars. He said, “I know that I am mortal by nature, and ephemeral; but when I trace at my pleasure the windings to and fro of the heavenly bodies I no longer touch the earth with my feet: I stand in the presence of Zeus himself and take my fill of ambrosia” (Tyson). At that time, reaching the “final frontier” was not even remotely possible.
In this paper I will clarify the relation between the integumentary system and the skeletal system. During this paper I will address how the two systems work together to maintain homeostasis and what occurs when balance is not maintained between the integumentary and skeletal system. During this paper I will explain how osteoporosis is directly linked between both the integumentary and skeletal system and ways to prevent or yield this disease.
Some of the organ systems of the body are the integumentary system, skeletal system, muscular system, nervous system, senses, and endocrine system. They are all equally as important to the survival of the human body. The first organ system that will be discussed is the integumentary system. The main purpose of the integumentary system is protection from infection, harmful rays of the sun, and cuts. Furthermore, the organs found in the integumentary system are the skin, hair, nails, sense receptors, sweat glands, and oil glands. The second organ system is the skeletal system. The skeletal system is made up of a total of 206 bones, 80 bones in the axial skeleton which is the trunk and head, and 126 bones in the appendicular skeleton which is the upper and lower extremities, and pelvis area. In addition, the main duties of the skeletal system are posture, aids muscles in movement, and heat production. The organs fou...

Human fascination with the stars is as ancient as Babylonians and has been suggested to be older than Stonehenge. From “be fruitful and multiply” to “live long and prosper,” the instinct to protect and propagate the species has manifested in religion, art, and the imaginations of countless individuals. As human understanding of space treks out of the fantastical and into the scientific, the realities of traveling through and living in space are becoming clearer. Exploring, investigating, and living in space pose an expansive series of problems. However, the solutions to the problems faced by mankind's desire to reach beyond the horizon, through the night sky, and into the stars are solutions that will help in all areas of life on Earth.
“Sheltered as we are by Earth's atmosphere and magnetic field, which deflect lethal radiation from space, we are like coddled children who have never ventured into a tough neighborhood” (Folger 2). Humans have been fascinated with space since the beginning of our time. Just like children and rough neighborhoods, we have tackled obstacle over obstacle to make it home again. In the end, we have a better knowledge and strength than before. The future of space exploration can assist us in answering the everlasting question of how the universe came to be. The more we explore the infinite galaxies, the more we can scientifically discover and create new technologies as science advances. As we continue to discover, we can create new fields and occupations for aspiring young students like myself.
