The musculoskeletal system is a complex arrangement of bones, muscles, cartilage, tendons, ligaments, joints, and other connective tissue. This system provides form, support, stability, and movement for the body. It is comprised of two separate systems, the skeletal system and the muscular system. Both of these systems are vital for the body to be able to function properly. For instance, the skeletal system protects and supports the weight of the body’s organs, serves as storage for calcium and phosphorous, and contains critical components for the production of blood.
What is the structure of the skeletal system? The skeletal system is made up of two parts, the first is the Axial skeleton and the second is the appendicular skeleton. The Axial skeleton is found in the core of the body, these bones are in place to protect the vital organs. Starting from the head there are 29 bones in the head. There is 8 cranial bones and 14 facial bones.
TASK 3.1 Write a report comparing and contrasting the structure and function of the three types of blood vessels. The Structure and Functions of Blood Vessels ARTERIES The walls of arteries contain smooth muscle fibre that contract and relax under the instructions of the sympathetic nervous system. The functions of the arteries are: transport blood away from the heart and transport oxygenated blood only. Arteries have four different parts, which are; lumen, endothelium, smooth muscle and connective tissue. LUMEN=the lumen of arteries is relatively narrow to maintain high blood pressure.
The musculo skeletal is made of bones, muscles, ligaments and tendons. The purpose of the musculo skeletal system is to protect , support and the overall function of the internal structures and organs of the body. Allow movement, give shape to the body, producing blood cells, storing calcium and phosphorus and producing heat. The skeletal system is made of bones and joints. The skeletal system provides the basic supporting structure of the body.
The supraspinatus originates at the supraspinatus fossa of the scapula and inserts at the greater tubercle of the humerus. Its function is to assists the deltoid abduct the arm while helping protect and stabilize the head of the humerus in the G/H joint. The infraspinatus originates at the infraspinatus fossa on the posterior surface of the scapula and inserts at the greater tubercle of the humorous. Its function is to adduct and laterally rotates the shoulder at the G/H joint while helping protect and stabilize the head of the humerus in the G/H
1. Explain the function of the heart, and the structure of the arteries veins and capillaries The heart is a key muscular organ, and is controlled by the autonomic nervous system. It transports blood to the body’s tissues via the circulatory system; blood provides the body with oxygen, nutrients and also assists in the removal of carbon dioxide and metabolic wastes, hormones are transported throughout the body by plasma. Arteries, arterioles, veins, capillaries and valves, are the blood vessels which are responsible for transporting the blood throughout the body. The arteries are thick walled muscular and elastic, three layered hollow tubes the thickness is needed to cope better with the pressure of blood flowing through the lumen of
Epiphyseal line is area of developing tissue and everyone has at least two, one at each end of bonePeriosteum is outer membrane which contains connective tissue, nerves and capillaries. It allows blood in and out of bone and help with growth and repair (PubMedhealth,n.d). compact bone provides the strength and protection of bones. It provides strong mechanical layers which with
These rods are connected at their base by the plantar fascia. When force is applied to the apex of the MLA, the arch depresses and the two rods separate then the tension is distributed throughout the plantar fascia. The main ligaments that aid in supporting the MLA are the long and short plantar ligaments and the calcaneonavicular ligament.
The Muscular System is an organ system that contains the skeletal, smooth, and cardiac muscles. It 's what makes the body able to move. Cardiac muscle a different than skeletal muscles because the main cardiac muscle is the heart which is controlled by the nervous system. Smooth muscles which are controlled directly by the autonomic nervous system and cannot be moved by conscious thought. Skeletal muscle system can all be moved voluntarily.
It is a noninvasive technique that means this signal is measured on the surface of human body which is used in identification of the heart diseases [17, 18]. Any disorder of heart rate or rhythm, or change in the morphological pattern, is an indication of cardiac arrhythmia which could be detected by analysis of the recorded ECG waveform. The amplitude and duration of the PQRS-T wave contains useful information about the nature of disease afflicting the heart. The electrical wave is due to depolarization and repolarization of Na+ and K ions in the blood . Electrocardiography is considered to be one of the most powerful diagnostic tools in medicine that is routinely used for the assessment of the functionality of the heart.
The non-striated (smooth) muscle cell is spindle-shaped and has one central nucleus. Smooth muscle contracts slowly and rhythmically. Cardiac Muscle Cardiac muscle, found in the walls of the heart, is also under control of the autonomic nervous system. The cardiac muscle cell has one central nucleus, like smooth muscle, but it also is striated, like skeletal muscle. The cardiac muscle cell is rectangular in shape.
Synergist muscles also help to create the movement. In the bicep curl the synergist muscles are the brachioradialis and brachialis which assist the biceps to create the movement and stabilise the elbow joint Type of contraction Concentric Contraction From the Sport and PE book by Kevin Wesson, Nesta Wiggins-James, Graham Thompson and Sue Hartigan I have gained some extra information on concentric contraction. Within the book it explains that this type of contraction involves the muscle shortening while contracting. A main example of this would be that this occurs during the upward phase of a bicep curl in the tricep. Eccentric Contraction An eccentric muscle contraction is a type of muscle activation that increases tension on a muscle as it lengthens.
It is divided into two sides which are connected together by nerve bundles called the corpus callosum. The left side or part controls the right side of your body where 's the right hemispheres controls the left side.The cerebellum,that lies towards the back of your brain maintains your body’s sense of balance and coordinates muscular movements with sensory information. It also regulates breathing, your breathing and other automatic
(Steve Parker 2007) The hearts wall are made of a special muscle known as cardiac muscle this type of muscle is only found in the heart because of its uniqueness, the muscle needs the ability to constantly contract without becoming weak or tired and to maintain this the muscle needs a continuous supply of oxygenated blood from the coronary arteries. The left and right side of the heart is divided by the septum, the septum also does not allow oxygenated and deoxygenated blood to mix and also helps support the
Calcium control is important because it lets the normal conduction of electric currents to run in our nerves and is also, the main element that causes our muscles to contract. The muscles contract when the brain signals and the body will pull calcium from the blood into the muscle cells. The calcium will then bind with the troponin, a complex of three regulatory proteins important to muscle contraction, which then draws it
