Recommended: Skeletal muscle summary

The three types of muscle in the human body are cardiac muscle, smooth muscle and the skeletal muscle. The skeletal muscle makes up around 40 percent of the body mass. The skeletal muscle is the only muscle that is voluntary. What I mean by voluntary is that you must first send a message to your brain and tell it to do something, then your brain tells your body what to do. The skeletal system also consist of 206 bones of varies shapes, size and functions. The skeletal system is actually broke into two sections, One section being the axial skeleton. This is made up of the 80 bone of the skull, spine, ribs and sternum or breastbone. The other section being the appendicular skeleton. This is made up of the 126 bones of the shoulder, arms, hands,

  • Skeletal Muscles Lab Report

    966 Words  | 2 Pages

    The production of physical movement in humans requires a close interaction between the central nervous system (CNS) and the skeletal muscles. Understanding the interaction behind the mechanisms of these two forces, and how they are activated to provide the smooth coordinated movements (such as walking or picking up a pencil) of everyday life is essential to the study of motor control. Skeletal muscles require the activation of compartmental motor units that generate their own action potentials, and produce a voltage force within the muscle fibers that can be detected and recorded with the use of a electromyography (EMG). Therefore, the purpose of this lab was to determine the differences between the timing of force production

  • Three Functions Of The Skeletal System

    238 Words  | 1 Pages

    The three functions of the skeletal system are to support, to allow movement, and to protect. The skeleton is the framework of the body and also cradles its soft organs, with it the body would be just a jelly mass it wouldn’t have no definite shape and would just collapse. It supports the softer tissues and provides points of attachment for more skeletal muscles to hold all of the parts of the body upright. For example, the bones of the legs as pillars to support the body trunk we stand up. It also supports the body against the pull of gravity. The skeletal allows movement. The skeletal muscle attached to the bones by tendons and uses the bones as a simple mechanical lever system to move the body and its parts. All together with the muscles

    The skeletal system protects the internal organs and soft tissues and is the structural framework that gives the body its shape. The skeletal system is composed of four parts: bones, cartilage, tendons, and ligaments. The skeletal system provides support, protection, allows body movements, stores minerals and fats, and is the site of blood cell production (Seeley, Stephens, & Tate, 2008). The appropriate development of the skeletal system allows an individual to walk, stand, pick up a pencil, and do everyday activities that involve movement and support. An individual without the appropriate development of the skeletal system will have difficulty performing everyday activities that require movement.

    This report will explore the structure and function of skeletal muscle within the human body. There are three muscle classifications: smooth (looks smooth), cardiac (looks striated) and skeletal (looks striated). Smooth muscle is found within blood vessels, the gut and the intestines; it assists the movement of substances by contracting and relaxing, this is an involuntary effort. The heart is composed of cardiac muscle, which contracts rhythmically nonstop for the entire duration of a person’s life and again is an involuntary movement of the body. The main focus of this report is on skeletal muscle and the movement produced which is inflicted by conscious thought unless there is a potentially harmful stimulus and then reaction is due to reflex, as the body naturally wants to protect itself. Skeletal muscle is found attached to bones and when they contract and relax they produce movement, there is a specific process that the muscle fibers go through to allow this to occur.

    The skeletal system frames our entire bodies and protects our fragile inner organs. We have two major types of bone in our body: compact bone and spongy bone. Compact bone is dense and looks smooth, while spongy bone is comprised of small needle-like pieces of bone with lots of open spaces. Our body contains 206 bones. The skeleton is separated into axial and appendicular sections. The axial skeleton includes the bones in the longitudinal axis of our body. The appendicular skeleton consists of the limbs and girdles of the body, such as our arms and shoulders. There are four different classifications of bone, determined by their shape. Long bones are shafts with ‘heads’ on both sides. Our limbs contain mostly long bones. Short bones

  • The Musculoskeletal System And Muscular System

    1372 Words  | 3 Pages

    The musculoskeletal system is made up of bones, muscles, cartilage, tendons, ligaments, joints and other connective tissue that supports and binds tissue and other organs together. Each muscle is a discreet organ constructed of skeletal muscle tissue, blood vessels, and nerves. Did you know there are roughly 600 organs that make up the muscular system? They include the cardiac muscles, smooth muscles, and skeletal muscles to name a few. The heart is the cardiac muscle. Smooth muscle are the tissues that line blood vessels and organs, such as the stomach and intestines. The skeletal muscles, which are the most well known and familiar of the muscle organ system, helps hold the skeletal frame work together. They make up bout 40 percent of the

    Although your teeth are also considered part of your skeletal system, they are not counted as bones. Your teeth consist of enamel and dentin. Enamel is the strongest substance in your body. The main priority of the skeletal system is to provide support for the body. Without bones our body would be in a pile of guts and mush on the floor. Your skeleton furthermore assists to protect your internal organs and fragile body tissues. The brain, eyes, heart, lungs and spinal cord are all sheltered by your

    The vertebral column is made up of 33 vertebrae that unite together to form a singular structure. The vertebral column lies in the middle of the body, from the base of the skull to just below the hip bones. The vertebral column is split into five separate sections. The Cervical, made up of 7 vertebrae, Thoracic, 12 vertebrae, Lumber, 5, Sacrum, 5 fused vertebrae and the coccyx, 4 more fused vertebrae. Each individual vertebrae are separated by interverbal discs that are joined together by ligaments and muscles.

    Some of the organ systems of the body are the integumentary system, skeletal system, muscular system, nervous system, senses, and endocrine system. They are all equally as important to the survival of the human body. The first organ system that will be discussed is the integumentary system. The main purpose of the integumentary system is protection from infection, harmful rays of the sun, and cuts. Furthermore, the organs found in the integumentary system are the skin, hair, nails, sense receptors, sweat glands, and oil glands. The second organ system is the skeletal system. The skeletal system is made up of a total of 206 bones, 80 bones in the axial skeleton which is the trunk and head, and 126 bones in the appendicular skeleton which is the upper and lower extremities, and pelvis area. In addition, the main duties of the skeletal system are posture, aids muscles in movement, and heat production. The organs fou...

In total, the human body consists of approximately 650 muscles (Shier, Butler, Lewis, 2009). The muscular system is divided into three types of muscle: cardiac muscle, smooth muscle, and skeletal muscle (p.212).

    The skeletal system is composed of two hundred and six bones in the human body. Functions such as the tendons, cartilage, and ligaments connect the bones and tissues together. Bone tissues make up about 18% of the weight of the human body. There are two types of tissue inside the bones. They consist of; compact bone and spongy bone. First, compact bone depicts the main shaft of long bones in the human body such as the arms and legs. Its tissue is dense and hard and it also makes up the outer layer of most bones in our body. Meanwhile, spongy bone tissue is made up of smaller plates occupied with red bone marrow. Mostly, it is found at the ends of long bones such as the head of the femur.
