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.
Stratum Lucidum III. Stratum Granulosum IV. Stratum Spinosum V. Stratum Basale 1.2.2. Dermis It is middle layer which contain connective tissue, sweat gland, hair follicles, collagen, blood vessels, nerves and various glands. Function of dermis layer is to provide strength, elasticity and to cushion the body stress and strain.
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.
(25) Histologically: fibroadenoma is composing of epithelial and stromal components; the epithelial part is made up of tubules consisting of cuboidal to low columnar cells, resting on a myoepithelial cell layer. And cellular fibroblastic stromas which contain loose connective tissue, the stromal cells are small, spaced; they show no cytologic atypia and little or no mitotic activity. (41) Complex fibroadenoma is called when there is morphologic variation as hyalinization, mixoid change, calcification, apocrine metaplasia and sclerosing adenosis. Malignant transformation in fibroadenoma rarely occurs, usually involving the epithelial component in the form of carcinoma in situ and invasive carcinoma (lobular and
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
Mod 10 Health/Wellness Assignment Name: Vedat Ulas Date: 11/6/15 Please find the following questions in your textbook: 1) Page B7, #1-5 1. Explain how the body is organized. The body is organized by the skeletal system the muscular system the nervous system digestive system the circulatory system and the respiratory system all of these systems are organized with cells, and tissue these make our organs and makes our systems. 2. Describe how the body systems affect one another.
Human body consists of several types of body systems that perform in collaboration with one another in sustaining a person’s health and life. Body system is defined as a complete framework that forms by multiple organs which work together in maintaining body function (Chiras, 2013). The main system in our body is categorized into three important systems namely respiratory system, cardiovascular system and urinary system (refer to Figure 1 in Appendix 1). One of the main body systems is the respiratory system. Respiratory system consists of two tracts which are the upper respiratory tract comprising only the conducting portion which transports air to and from lungs and the lower respiratory tract that includes both the conducting portion
The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them. The skeletal system performs vital functions; support, movement, protection, blood cell production, calcium storage and endocrine regulation that enable us to survive. Below are more details on the exact role the skeletal system has on; protection, shape, support, movement and blood production:
That structure is called a double helix. DNA is located in the nucleus of a cell. The nucleus is generally in the center of a cell. A typical cell nucleus is so small that ten thousand could fit on the tip of a needle. One strand of DNA is around 6 feet long.
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.
The PNS contains somatic nervous system and the autonomic nervous system. The autonomic nervous system controls the function of internal organs like your heart, stomach, cardiac muscle, and your glands. The autonomic nervous system has an effect on the organs, muscles, and glands are all done voluntary. The autonomic nervous system can change the body temperture, send extra blood to a particular area, slow your heartbeat, and pull the stomach secretion. The somatic nervous system is made up of sensory organs and nerves that connects to the skin, also that connects to all the skeleton muscles.
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
