Smooth muscle Essays

INTRODUCTION Muscle tissue is one of the four primary tissue types consisting elongated muscle cells that are highly specialized for carrying out certain responsibilities. Muscles are responsible for movement of different parts of the body; posture; respiration; production of body heat; communication; constriction of organs and vessels and contraction of heart. General properties of muscles: Contractility is the ability of muscle to shorten forcefully although its shorten forcefully, it lengthens

File one Summary: Skeletal muscles are made out of striated subunits called sarcomeres, which are made out of the myofilaments actin and myosin. Skeletal muscles contain myofibrils. Every myofibril is striated with dull and light bands. I bands contain just thin fibers, made fundamentally out of actin. Myosin cross bridges stretches out from the thick fibers to re slim fibers. Very still, the cross bridges are not connected to actin. The cross-bridge heads capacity as ATPase enzymes. ATP is split

MUSCLE TYPES In the body, there are three types of muscle: skeletal (striated), smooth, and cardiac. Skeletal Muscle Skeletal muscle, attached to bones, is responsible for skeletal movements. The peripheral portion of the central nervous system (CNS) controls the skeletal muscles. Thus, these muscles are under conscious, or voluntary, control. The basic unit is the muscle fiber with many nuclei. These muscle fibers are striated (having transverse streaks) and each acts independently of neighboring

Did you know that there is injustice in the play A Doll’s House by Henrik Ibsen? The men in A Doll’s House treat women differently than how they treat other men. To society at the time men were above women. This idea is supported by the way that Nora is treated like a child by her husband Torvald, the way Nora has to follow all her husband’s decisions, during that time period women didn't typically have a job or education. When all of the evidence is presented the reader can therefore decided whether

half of a human 's body weight is composed of muscle. There are three distinct types of muscle tissue: cardiac muscle, skeletal muscle, and smooth muscle. Each of the muscle tissues have different structures, properties, characteristics, and roles in our body. Properties of muscle tissues include excitability, contractility, extensibility, and elasticity. Contractility is the ability to shorten, which causes movement of the structures to which the muscles are attached. Excitability is the ability to

“Where Are You Going, Where Have You Been?” is a short story detailing the coming of age of a teenage girl named Connie and the predatory advances made on her by a man named Arnold Friend. It was adapted into a film titled Smooth Talk which expands upon the short story by providing more characterization to both Connie and the various people around her. “Where Are You Going, Where Have You Been?” is told in a third-person limited omniscient perspective. Connie acts as the story’s protagonist, and

Compare and contrast Anne’s relationship with her mother to that with her father. (Double Bubble Map) Started Monday, January 9th Anne respects and appreciates her father more. And also, she always criticises whatever her mother does. But later in the story Anne respects her mother more. Also Anne appreciates what her mother does for her and the sacrifices she made. Throughout the whole story Anne appreciates and respects her father. And Anne prefers to go to her father with problems rather than

Which one do you fear: Octopuses or Squids? The seven oceans contain thousands of organisms, which create an aquatic ecosystem. Some of these organisms are peaceful friends, but some are ruthless killers. Throughout the history of marine species, octopuses and squids have been described as monstrous creatures, which appear as homogeneous species, but they contrast with each other. Sharing various comparable traits and physical features, made it confusing for humans to organize them in the classification

Smooth muscle The function of the Smooth muscle are the muscle we do not consciously control eg those that are found in the walls of blood and lymphatic vessels, in respiratory, digestive and genito-urinary systems. These muscles work automatically weather we want them to or not. The structure of the smooth muscle is they have spindle shaped cells with no distant cell membrane and only one nucleus, bundles of the fibre we see with the naked eye. Skeletal muscle the function is these are the muscle

consists of many tissues, but the three main types of tissue that make up the heart are; cardiac muscle tissue, nerve tissue and blood tissue. The cardiac muscle tissue is only found in the heart. It plays the most important role in the atria and ventricles of the heart. It contracts and makes the rhythmical beating of the heart and circulates the blood around the body, making the heart pump. The cardiac muscle sends electrochemical signals all around the heart so that all the cells in the body receives

chemical that binds to a receptor and activates the receptor to produce a biological response thereby enhancing the normal response. Acetylcholine is secreted by the post ganglionic neutron in the parasympathetic system this mediates contraction in smooth muscle via the type 2 muscarinic receptors (Flavio 2018). Muscarinic receptors are G-protein linked (Gq) which up regulate phospholipase C and thereby inositol triphosphate giving a rise to intracellular calcium. Activation of M3

fibers) that located in places like the ear. collagen may be found in connective tissue and the bones and that provides structure and support. (Cinnamon L. , 80) The function of muscular tissue is contracting and producing movement. Moreover, the muscle tissue controls posture, body temperature and supports soft tissues.

Without the muscular and skeletal system we would be blobs of water filled tissue. The muscular system is made of more than 600 muscles and each muscle plays an important part. Like the muscles of our heart and the smooth muscles of our organs. Without muscles we wouldn’t be able to move our body, because it helps us keep our posture and it secures our joints. Our muscles connect to our nervous system which sends a nerve signal to the brain when we want to do something. The skeletal system is made

femoral head is attached to the rest of the femur by a short section of a bone called femoral neck. A large bone protruding out from the top of the femur which located next to the femoral neck is called the greater trochanter. Large and important muscles connect to greater trochanter. Figure 1: Showing the anatomy of the hip joint In the hip, Articular cartilage covers inner parts of the femur and socket portion of the acetabulum in the pelvis. The cartilage is especially thick in the upper

his mother is the carrier (2, 3). Symptoms for DMD are confinement to a wheel chair by the age of 11at the latest and are expected to die in their twenties to forties (2, 4). This is because DMD causes progressive muscle weakness and will reduce muscle tone throughout the body. Muscle weakness will usually begin its onset by the age of three (4). Other symptoms for DMD include pseudohypertrophy (the growth of an organ or a part due to an increase in the amount of other tissue that is fatty

1. What is the mechanism of injury for a sternoclavicular sprain? In the majority of sternoclavicular sprains, what is the direction of clavicle displacement? The majority of injuries result from compression related to a direct blow, as when a supine individual is landed on by another participant, or more commonly, by indirect forces transmitted from a blow to the shoulder or a fall on an outstretched arm. The disruption typically drives the proximal clavicle superior, medial, and anterior.

Deep Tissue - Focused on realigning deeper layers of muscles and connective tissue, this massage is especially helpful for chronically tense and contracted areas, such as: stiff necks, low back tightness and sore shoulders. Using some of the same strokes as a classic Swedish massage (but moving slower), the therapist applies deeper pressure concentrated on areas of tension and pain. Trigger Point - A trigger point is a tight area within muscle tissue that causes pain in other parts of the body. A

they remain stable and constant. What are Tissues? Tissues are comprised of individual cells and are one of the main building blocks of an organism. All the cells in a tissue do the same job. There are four basic human tissues, connective tissue, muscle tissue, epithelial tissue and nervous tissue. In each of the types there are different kinds of tissue but they all do a similar job. Connective tissue is simply what

Pilates is a method to condition the body using exercises that strengthen and stretch muscles. Since its creation ninety years ago, people widely practice it all over the world, making it a favored class in gyms and health clubs. Pilates exercises draw from traditional yoga techniques along with strength-building principles used in the traditional gym setting. It works the body as one unit instead of working individual parts separately. The Pilates Method provides a wide variety of benefits by connecting

Cardio Respiratory Endurance Cardio Respiratory Endurance is the ability for the heart and lungs to supply oxygen to the body for a prolonged period of physical activity. The area of the body that this takes place in is the cardiorespiratory system (subsists of the heart, blood vessels, and respiratory system). The bellow figure shows the cardiorespiratory system. I tested my Cardio Respiratory Endurance by doing the beep test. As a result, I achieved an average score of 8.5. A table of scores
