Muscular system

The function of the muscular system is to allow you to move.It also lets your bones move.

The organs are the three muscle types, the Visceral muscle, the cardiac, and skeletal muscle. The smooth muscle (visceral) is found inside of organs like the stomach, intestines, and blood vessels. The cardiac muscle is found only in the heart, and it is responsible for pumping blood throughout the body. And last the skeletal muscle, it is the only muscle that is controlled consciously. Every physical action that a person performs (e.g. speaking, walking, or writing) requires skeletal muscle. Most skeletal muscles are attached to two bones across a joint, so the muscle serves to move parts of those bones closer to each other.

Interactions: The muscular system works with the nervous system, that makes sense since you usually have to think before you can move. the neurons of the nervous system are connected to most of the cells in your muscular system. So when you think to move something it moves.

Analogy:

The muscular system is like an assembly line because each muscle is doing a different job to do one main job, move, in an assembly line each person is doing a certain job to make one project. With the muscular system, each muscle does some part to walk,write,etc.

Structure and Function: The skeletal muscle looks the way it does because it has to act like a bone that you can move so if it is a bunch or rods together it can connect to the nervous system and letting you control this type of muscle. If the skeletal muscle is supposed to be movable of course it should be a section of rods that can connect to the nervous system, you need to think to move the certain part.

Amedeo Avogadro - 5/27/18

Image
Summary : Amedeo Avogadro was an Italian scientist who created what is now known as Avogadro's law. Known as a founder of the atomic-molecular theory, he was the first scientist to realize that elements could exist in the form of molecules rather than as individual atoms. His biggest contribution to science, Avogadro’s law, states that equal volumes of gasses under the same conditions of pressure and temperature will contain an equal number of molecules. Amedeo Avogadro was born on August 9th 1776 to Filippo Avogadro and Anna Maria Vercellone. Coming from a family of lawyers, Advogadro was guided to a legal career, and became a bachelor of jurisprudence in 1792. Despite a successful legal career; Avogadro has started private studies of mathematics and physics, which then he pursued full time. SP8 - Communicating Information : This week, I communicated information in the form of a wanted poster about a certain scientist. I decided to create a wanted poster about Amedeo

How Stress Affects the Brain - 5/13/17

Image
Summary : Stress takes a variety of forms. Some stress happens as the result of a short-term event such as having an argument with a loved one. Other stress happens due to recurring situations, such as working a demanding job. When recurring situations cause stress that is both intense and sustained over a long period of time, this is known as chronic stress. Even though all stress triggers physiological reactions, chronic stress is a big problem because of the significant harm it can do to the body and the brain. When someone experiences a stressful event, an area of the brain that contributes to emotional processing sends a distress signal to the hypothalamus. This area of the brain functions like a command center, communicating with the rest of the body through the nervous system so that the person has the energy to fight or flee. This “fight-or-flight” response is responsible for the physical reactions most people correlate with stress including increased heart rate

Roller Coaster Project Blog - 2/18/18

Summary : A roller coaster ride is a thrilling experience which involves a lot of physics. Part of the physics of a roller coaster is the physics of work and energy. The ride often begins as a chain and motor which exerts a force on the train of cars to lift the train to the top of a vary tall hill. Once the cars are lifted to the top of the hill, gravity takes over and the remainder of the ride is an experience in energy transformation. At the top of the hill, the cars possess a large amount of potential energy. Potential energy is dependent upon the mass of the object and the height of the object. As the cars descend the first drop they lose much of this potential energy in accord with their loss of height. The cars subsequently gain kinetic energy. Kinetic energy is dependent upon the mass of the object and the speed of the object. Therefore, their original potential energy is transformed into kinetic energy.
