The three individual muscle types also serve five main functions. The five basic functions are movement, organ protection, pumping blood, aiding digestion, and ensuring blood flow. The first basic function of the muscular system is movement, which is carried out by the skeletal muscles. The primary function of the skeletal muscle is to produce voluntary gross and fine motor movement. This set of voluntary muscles provides the forces that enable the body to move.
The primary function of the muscular system is to aid in different movements – such as walking, running, and jumping. It also handles a couple of involuntary actions, like the beating of your heart. The major organs of the muscular system are the skeletal, smooth, and cardiac muscles. Skeletal muscles control voluntary actions that are preformed consciously, and are the only muscles that do so. Most skeletal muscles are connected across a joint, and serve to contract to move different parts of the body closer to or farther away from each other, such as your bones.
These disks contain desmosomes, which hold the fibers together, and gap junctions, which allow muscle action potential to spread from one cardiac muscle to another. In cardiac muscle fibers, calcium ions enter the sarcoplasm both from the sarcoplasmic reticulum and from extracellular fluid. The mitochondria in cardiac muscle fiber are larger and more numerous than in skeletal muscle fiber. Cardiac muscle fibers can also use lactic acid produced by skeletal muscle fibers to make ATP, a benefit during exercise.

Muscles have many reasons and in this paper you will widen your knowledge of muscles and their functions as well their diseases and how they help maintain the body. There are three different types of muscles in the body, and the first to be talked about are skeletal muscles. The body consists of about 640 skeletal muscles and they just so happen to be the only voluntary or (controlled) muscles. Their main function is to contract and expand so that your bones are able to move. Most skeletal muscles are attached to bones or joints so that the muscle can either expand or contract to create motion.
Smooth muscle is found in blood vessel walls and lining the walls of visceral organs. Each type of muscle is structured to best provide the body with the movements it needs internally and externally. Almost every essential function in the body, whether it is breathing, digesting, controlling blood pressure or simply walking requires muscle tissue. Both skeletal and smooth muscle use actin and myosin to build their contractile elements, however their arrangement is different. In both muscle types there are two types of filaments: thick and thin.
The musculoskeletal system is made up of bones, joints, and muscles. This system gives the body form and support, and protects the body while allowing it to move. Basically, the muscles in this system perform three important body functions: the movement of body parts, maintenance of body parts, and production of body heat. These muscles all consist of a mass of protein fibers grouped together, and most are of mesodermal origin. And almost all of the muscle fibers you will ever have or need were present at birth.
Muscular system is a system which consists of specialized cells which called as muscle fibers. The main function of muscular system are allows the body movement, circulates the blood throughout the body, helps to maintain the posture such as standing and sitting and also function as heat production which helps to maintain the body temperature. Human body would not able to move at all without muscles. In human body there are more than 600 muscles and most of the muscles attached to the skeleton. Muscle system can be divided into three types of muscles which is the cardiac muscle, skeletal muscle and also smooth muscle.
All of above plus muscle strain in the back, neck, head and legs that allow us to adopt an upright position, whether you are sitting or standing. “The human body contains 640 different muscles” each one performing a specific function. Whole muscle contributes to “40 – 50% of our body weight” (Srivastava & Chosdol, 2007). “The muscular system consists of highly specialized cells called muscle fibers” (Srivastava & Chosdol, 2007). The features of each muscle fiber define the strength with which it contracts and the specific function it does.
Skeletal muscles are made up of many smaller units called muscle fascicles, and those are made up of even smaller units called muscle fibres. A muscle fibre is a single cell that contracts when stimulated. It is made up of bundles of myofibrils, thick and thin filaments arranged in sacromeres. Skeletal muscles vary considerably in size, shape and the arrangement of these muscle fibres. 3.
The point... ... middle of paper ... ... affected the data table. Not going in 0.5 intervals for every muscle at every workload would conclude to inaccurate data if not all electrical stimuluses’ were tested. In conclusion, this lab was performed to see if various electrical stimulations and workload weights had an effect on different types frog muscles. This lab is crucial to real world applications because muscles are present in every living organism – and mainly beneficial to humans. There are many different types of muscles containing a range of functions that are crucial to movement in the human body that we use from day to day.
