Muscular system

Image result for 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.

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. Backward-Looking:  How much did you know about the subject befor...

The Designer Species Project - Project Blog 11/5/17

Summary: The Fobra is a new species of frog with the body of a red-eyed tree frog, the eyes of an owl, the fangs of a king cobra, and the claws of a squirrel. Since the fobra lives in planet C, a tropical planet with much rainforest and vegetation, our frog can "nest" itself in the plants to stay warm. To stay cool the fobra can soak itself in puddles and absorb the moisture. The fobra is also a warm-blooded animal. The fobra uses both its tongue and teeth to eat, depending on the size of animal it is eating. With the claws similar to squirrels, the fobra will be able to get away and climb up on trees faster, making predators unable to get it. As well having the bite similar to the king cobra, our species will bite predators when it feels threatened or scared by predators that are after them. The fobra will be able to strike extremely quickly, like a cobra, in self-defense. Red-eyed tree frogs will lay clutches of eggs on the underside of leaves that are standing abo...
