The human muscular system, like any other system in the human body, is very complex. All the moving parts (anatomy), and how they work together to perform specific actions (physiology). There is so much that can be done to help the muscles in your body perform strenuous activities before fatigue, before your muscles run out of the fuel required to continue to perform movements. The biggest question most young adults want to know is, how do you get bigger muscles? Or, why do I cramp during workouts? All these and more can be answers through the understanding of the anatomy and physiology of the human muscular system.
First let’s go over four very important factors of the human muscular system. First being the primary function of the muscular system is movement for the body. The nervous system communicates with the muscular system, resulting in movement. Second is the five major properties of the muscular system beginning with 1) our muscle being excitable or irritable. 2) Our muscles are contractible. 3) Our muscles are extensible. 4) Our muscles have elasticity. 5) Last, our muscle system is adaptable. Third, there are five types of muscle movements. 1) Adduction, movement towards the body. 2) Abduction, movement away from the body. 3) Flexion, “movement in the anterior-posterior plane that reduces the angle between the articulating elements.” (Martini, F 230). 4) Extension, “occurs in the same plane as flexion, but it increases the angle between articulating elements.” (Martini, F 230). 5) Last is rotation. Fourth, there are three main types of muscles, which consist of, 1) involuntary cardiac muscles. 2) Involuntary visceral/smooth muscles. 3) Last are the voluntary skeletal muscles.

...ese elements can cause complications during muscle contraction and relaxation? The answer is yes. Lacking enough salt and potassium in your diet, may lead to cramping of muscles during strenuous activities.
Now for the factors that can happens to your muscles. Most people want to achieve hypertrophy. Hypertrophy is “an enlargement of the stimulated muscle.” (Martini, F 224) Another factor that can occur in your muscles is known as atrophy. “A skeletal muscle that is not regularly stimulated by a motor neuron loses muscle tone and mass.” (Martini, F 224) This leased to a decrease in muscle size and strength.
In conclusion, to maintain homeostasis in the human body, one must perform two of the hardest tasks asked from a person. Maintain a proper diet to maintain a healthy, functional muscular system, and conduct regular physical activities to achieve hypertrophy.

- ... For example refer to figure 1-1 1-4 and1-5 for the cell Another type of muscle is the smooth or (visceral) muscle. It is the weakest of all muscle tissue and is located in the hollow organs inside the body to move substances such as urine or blood. The smooth muscles like skeletal muscles also contracts for movement, but instead of moving bones, smooth muscles move substances through organs such as the stomach by contracting or squeezing to push the substance through the organ where it can be digested....

- This assignment is based on the case study of Leigh Richards (School of Nursing & Midwifery 2013). Leigh Richards is a 39-year-old male who has three (3) children, he lives in Murray Bridge and works as an irrigation consultant; Leigh was in a rally car as it crashed into a tree while going high speeds on a dirt road. Leigh has been diagnosed with pneumothorax and a small subdural hematoma but these will not be discussed within the assignment (School of Nursing & Midwifery 2013). This paper will encompass the anatomy and physiology of the skeletal and muscular system, the pathophysiology that relates to the areas surrounding the diagnosis of injury that Leigh has acquired, two of the signs a...

- ustin Youssef Anatomy and Physiology Paper #4: Nerve Anatomy The nervous system is an imperative part of the human body that assists in the transmission of signals across several different parts of the body. It also releases messages back and forth from the brain to the different parts of the body and coordinates the voluntary and involuntary action of the body. At the cellular level, the nervous system consists of a cell called a neuron, also known as the nerve cell. The neurons connect via synapses that act as a pathway connection that transmit signals to other cells.... [tags: Nervous system, Neuron, Spinal cord, Nerve]

- Explain Anatomy and Physiology of Human Respiratory System Introduction Our respiratory system is fundamental to our living. Without the use of our respiratory system and oxygen reaching all parts of our body we would not be able to function and parts of our body would start to die. It is so important that we maintain this system and keep it healthy. In this report we shall look into how the respiratory system is made up of cells and tissues, how it functions and the effects smoking can bring.... [tags: Cell, Organelle, Eukaryote, Cell nucleus]

- The body is a physical structure composed of the skeletal, muscular, endocrine, digestive, circulatory, respiratory, excretory, and the one I am representing, nervous, systems, yet the most priceless and vital one that surely should not be laid off is the nervous system. The nervous system consists of two sections. The first is the central nervous system (CNS). The CNS, which coordinates the activities of the entire nervous system, is composed of the brain (cerebrum, cerebellum, and medulla), and the spinal cord that is connected, via the brain stem, to the brain; nerve cells carry impulses from it....

- Respiration consists mainly of two processes.Respiration Internal or cellular respiration is the process by which glucose or other small molecules are oxidized to produce energy: this requires oxygen and generates carbon dioxide. External respiration (breathing) involves simply the stage of taking oxygen from the air and returning carbon dioxide to it. “Anatomy and Functions of Respiratory System and its Components” The respiratory tract, where external respiration occurs, starts at the nose and mouth....

- In Labs 22 through 26, my lab partner and I were assigned a fetal pig to perform a dissection on in order to understand anatomy, the study of an organism’s structure1, and physiology, the study of the functions and activities of a living organism2. Throughout these labs, we studied the structure of the fetal pig and performed experiments to understand four system processes: digestion, cardiovascular, respiratory, and excretory. Dissecting an organism, physically moving and seeing the different portions of the organism, especially of a fetal pig, is very important.... [tags: Blood, Heart, Digestion, Circulatory system]

- ... The contractions are voluntarily controlled by motor neurons originating from the spinal cord and by specific neurotransmitters; mainly the neurotransmitter acetylcholine (Campbell, 2012). The bundles of cells that produce these voluntary, vigorous and rapid contractions are multinucleated and cross-striated (Mescher, 2013). Cardiac Muscles Cardiovascular muscles are specific muscles that are found in the external layer of the heart (Paulsen, 2010). Cardiac muscles, like skeletal muscles are composed of cells containing several nuclei.... [tags: keletal, cardiac, and smooth muscles]

- It usually goes unnoticed by the average human, but you take a breath twelve to sixteen times per minute, every single day. This is made possible by the respiratory system. The respiratory system is the group of organs in the body that enable a person to breathe; this system, like the other systems, is vital for survival. The respiratory system’s main function is gas exchange, which in turn maintains normal blood pH, maintains body temperature, and keeps cells alive to sustain the body. The respiratory system provides a person’s sense of smell, and a person’s voice and sounds they can make are possible due to this system.... [tags: Respiratory system, Larynx, Mucus, Oxygen]

- Dinosaur Physiology and Questionable Four Chambered Heart Discovery In recent years, there has been cardiovascular evidence that questions the widely held belief that dinosaurs were indeed ectothermic. There was a discovery of a skeleton encased in sandstone that closely resembled a Thescelosaurus. The set of bones had a heart shaped rock within the chest region. Tests are being done to find out if this heart is in fact the suggested four-chambered heart. If it is, then there could be important changes in the theories of dinosaur physiology....
