The muscles are a structure in ways that they have myofilaments that form sarcomeres. The sarcomeres form the basic unit of striated muscles that enable the muscles to perform their functions effectively. The fibers making the sarcomeres are made of proteins, and this is the points where muscles contracts and relaxes. The contraction and relaxation of the muscles lead to the movement of the limbs. Energy is required in the allowing the muscles to contract or relax.…
There are three types of muscles in the human body: cardiac muscle, smooth muscle and skeletal muscle. For the purpose of our lab we will be focusing only on skeletal muscle. Skeletal muscle is the only voluntary muscle tissue found in the human body. They're attached to bones by tendons and are responsible for all the movements that are consciously controlled such as writing, walking, running, etc. [1].…
The muscles of the muscular system keep bones in place; they assist with movement by contracting and pulling on the bones. To allow motion, different bones are connected by joints which are connected to other bones and muscle fibers via connective tissues such as tendons and ligaments. Cartilage prevents the bone ends from rubbing directly on each other. Malnutrition and arthritis are examples of disorders and diseases in the body that can severely impair the function of the musculoskeletal system.…
The skeletal muscle system is made of many skeletal muscle fibers which have at least one neuromuscular junction. A neuromuscular junction is the area of the skeletal muscle fiber that is innervated by a motor neuron (motor nerve). It plays a key role in body movement and breathing along with our nervous system. The synaptic knob, motor end plate, and the synaptic cleft are all key parts of the neuromuscular junction. The synaptic knob of an axon connects with a skeletal muscle fiber to form the neuromuscular junction.…
1. Explain the relationship between the skeletal and muscular systems. The relationship between the skeletal and muscular systems is that the muscular is responsible for the movement of the human body. Which is attached to the bones of the skeletal system. The skeletal performs vital functions like support, protection, and movement.…
The smooth muscle tissue is found inside organs like the stomach, the blood vessels and the intestines. The smooth muscle tissue is an involuntary muscle, meaning it functions on its own without been controlled. The main function of the smooth muscle tissue is to make organs tightens to move substances in and out of the organs, and it is mainly controlled by the unconscious part of the human brain. The second type of muscle tissue is the cardiac muscle and it is found in the heart. This muscle is responsible for the flow of blood throughout the body.…
Running Head: FROM THE OUTSIDE IN 2 ABSTRACT ALS also known as Lou Gehrig's, is a disease where your body attacks its own muscles. This research project will explain a lot of information on the terrifying disease of ALS. It will include the signs and symptoms of the disease, and the risk factors it takes to get ALS. It will also explain how and if the disease can be diagnosed by different test and when these test occur.…
Then there is the Cardiac which is only found in the heart, it is responsible for pumping blood through the body. Lastly there is the smooth muscle which is the type of muscle found in our internal organs, blood…
Human body Today I will be talking about how the systems work together. One example is the the skeletal and the muscular system, they work together by Your bones and muscles work together through a series of impulses and signals communicated between the brain and skeletal muscles. In order to move, the nervous system then sends signals a skeletal muscle to contract. The muscular system is the mechanical force behind the digestive system. Beginning when you take a bite, your muscular system aids your digestive system.…
The interstitial cells of Cajal control the smooth muscle activity and the autonomic nervous system relays the message from input for the smooth muscle. o Neuropeptides, hormones and neurotransmitters affect gastric emptying • Anatomical controls: o Sphincters: esophageal and stomach LES, which controls the release of food into the stomach and prevents from reflux • Nitric oxide and VIP inhibit closure of LES • Secondary peristalsis occurs if not all…
1. The peripheral nervous system, which is divided into the sensory and motor divisions, is involved in physical sensation. Sensory impulses move though the body by being stimulated by a receptor in the skin. It then travels to the sensory neurons and through the afferent fibers, were it will end up at the spinal cord as well as the brain.…
Alzheimer 's disease Alzheimer’s disease is a fatal disease that affects the central nervous system (CNS) and other systems of the body. The CNS includes the brain and spinal cord. The digestive system is affected by Alzheimer 's, this system includes; the mouth with salivary glands and teeth, pharynx, esophagus, stomach, small intestines, large intestines, rectum, and anus. The Urinary system includes the kidneys, ureter, urinary bladder, and the urethra. The neuromuscular system is affected as the disease progresses, this includes the nerves and muscles of the body.…
To understand the Musculo-Skeletal system and how it is suited to the functions that it performs for the body you first need to understand how the system works and what it is responsible for. It is comprised of two separate systems working together as one to provide the body with physical support, the ability to move and protection for its major organs. These two systems are the Skeletal System and the Muscular System and they contain the following:- Bones of the skeleton Muscles Cartilage Tendons Ligaments Joints Connective tissue binding to the body’s organs If you break the system down into its separate parts you can gain a deeper understanding of how they create a joint working system within the body.…
In this assignment I will be explaining the physiology of two body systems, the cardiovascular system and the respiratory system in the relation to energy metabolism in the body. Energy metabolism is where energy is generated from nutrients and delivered to the organs around the body. Energy is needed in the body in order muscular movement, circulation of the blood, lymph and tissue fluid, breathing process, cell growth and repair, the transition of nerve impulses and for the building of different complex molecules. The cardiovascular system There are four major functions of the cardiovascular system, these include: the transportation of nutrients, gases and waste products around the body, the protection of the body from infections and blood…
For example, when you think of moving your leg using your quadriceps, the brain directs a signal down a nerve cell to your quadriceps muscle to contract. The amount of muscle being contracted depends on the signal that the nerve sent. A muscle is consisted of a lot of conjoined cells called fibers. Imagine these fibers as elongated cylinders.…
