Muscular System

  1. 1. MUSCULAR SYSTEM Reported by: DONABEL E. REYES MA'AM JOY ADAMOS Instructor
  2. 2. Muscular System  The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person’s body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves. Muscle tissue is also found inside of the heart, digestive organs, and blood vessels. In these organs, muscles serve to move substances throughout the body.
  3. 3. PRIMARY PURPOSE OF MUSCULAR SYSTEM:
  4. 4. Functions of the Muscular System  Body movement  Maintenance of posture  Respiration  Production of body heat  Communication  Constriction of organs and vessels  Heart beat
  5. 5. DIVISIONS OF MUSCLES Appendicular muscles • Control the movements of the upper and lower limbs, and stabilize and control the movements of the pectoral and pelvic girdles.
  6. 6. Types of muscle tissue:
  7. 7. Skeletal Muscle With its associated connective tissue, constitute approximately 40% of the body weight. Skeletal muscle is so named because most skeletal muscles are attached to the skeletal system. It is also called STRIATED MUSCLE because the transverse bands or striations that can be seen in the muscle under the microscope.
  8. 8. 5 functional characteristics of skeletal muscle: 1. EXCITABLE or IRRITABLE 2. CONTRACTIBLE 3. EXTENSIBLE 4. ELASTICITY 5. ADAPTABILITY
  9. 9. Example of adaptability:
  10. 10. Muscle Attachment
  11. 11. MUSCLE CONTRACTIONS ~> Is the movement of muscle fibers in response to force or load.  CONCENTRIC > the muscle shortens in length as it overcome resistance.  ECCENTRIC > the muscle increase in length to accommodate resistance.  ISOMETRIC > the muscle resists outside stress w/out exhibiting motion.

It usually occurs in athletes who overtax the muscle to w/c the tendon is attached. Disorders and Other Conditions of Muscle tissue
  29. 29. EFFECTS OF AGING ON MASCULAR SYSTEM  There is loss of muscle fibers as aging occurs. The loss begins as early as 25 years of age and by 80 years of age, the muscle mass is reduced by approximately 50%.  Aging is associated with a decrease in density of capillaries in skeletal muscles, and after exercise, a long period of time is required to recover.  Age related changes in skeletal muscle can be dramatically slowed if people remain physically active. It has been demonstrated that elderly people who are sedentary can become stronger and more mobile in response to exercise.  First sign of aging in the muscular system starts at the age of 40.  At the age of 80: Decline in motor neuron activity leads to muscular atrophy, diminished muscular strength and slower reflexes.  Aerobics and strength training exercises can help maintain a healthy muscular system.
