Devonne Lozada Living Environment 1/8/13 Mr.Jorez Human Muscular System Visceral muscle is found inside of organs like the stomach‚ intestines‚ and blood vessels. The weakest of all muscle tissues‚ visceral muscle makes organs contract to move substances through the organ. Because visceral muscle is controlled by the unconscious part of the brain‚ it is known as involuntary muscle—it cannot be directly controlled by the conscious mind. The term “smooth muscle” is often used

Skeletal‚ Muscular‚ and Integumentary System The Muscular System Our muscular system provides the main source of force to put our bodies into motion. More than 40% of our body mass is composed of muscle. Types of Muscular Tissue There are three types of muscle tissue: 1. Skeletal Voluntary movement‚ attached to bones. 2. Smooth Involuntary movement‚ found in digestive tract‚ circulatory system‚ etc. 3. Cardiac Involuntary movement‚ found only in heart. Muscle Contraction Skeletal Muscle

The Muscular System Teacher pages The muscular system allows us to move. Adults have a certain fixed number of muscle cells‚ approximately 602. . Through exercise‚ such as weight lifting‚ the cells enlarge but the number of cells does not increase. Structure and Function There are three types of muscle tissue—smooth‚ skeletal‚ and cardiac. Each has its own distinctive function‚ and therefore‚ its own distinctive structure‚ but all muscles allow movement of some kind. Skeletal Muscle

May 30‚ 2010 The Cardiovascular and Muscular Systems Organ system is a group of organs that work together to perform a certain task. Humans have a variety of systems due to the complexity of the species’ organism. The human body consists of biological systems‚ that consist of organs‚ that consist of tissues‚ that consist of cells and connective tissue. Although an organ has a specific function‚ organs also function as part of a group. The organ system is the organizational unit by which

The structures and functions of organs determine their relationships within body systems of an organism. Homeostasis allows the body to perform its normal functions.

able to exert great bodily or muscular power. Another component of muscular fitness that is crucial is muscular endurance‚ which is the ability to perform a specific muscular action for a prolonged period of time. For example‚ performing 50 squats with a weight of 50 kilograms on the shoulders requires both attributes‚ 150 squats without weight requires more muscular endurance while the ability to perform a single squat with a weight of 200 kilograms depends on muscular strength.

carry full investigation and analysis on the Skeletal system‚using my class notes‚researching on the internet and reading books. The Skeletal system is the system of bones‚ associated cartilages and joints of human body. Together these structures form the human skeleton. Skeleton can be defined as the hard framework of human body around which the entire body is built. Almost all the hard parts of human body are components of human skeletal system. Joints are very important because they make the hard

Muscular Strength and Endurance Lab The purpose of this lab was to provide muscular fitness tests to assess upper and lower body muscular strength and muscular endurance using resisted exercise or exercise machines. This was done through a number of tests including: max push-ups‚ max curl-ups‚ bench press‚ and leg press. Using a chart‚ the student was able to compare their max repetition of each exercise to the normal range for their age group. Muscular fitness tests are classified as increasing
