• Muscular System

  Organ system for enabling body movement and maintaining normal body temperature
• Muscle components

  • Muscle cells
  • Muscular Fiber
  • Muscles
  • Epimysium
  • Perimysium
  • Endomysium
  • Sarcolemma
  • Fascicles
  • Muscle Fiber
  • Contractile Units Myofibrils
• Z Line

  Boundaries between two sarcomeres
• Sarcomere

  Area within two Z Lines
• Relaxation

  Thin Filament (Actin)
• Contraction

  Thick Filament (Myosin)
• Types of Muscle

  • Three Types of Muscle
• Antagonistic Muscle Pairs


  Muscle pairs that work against each other
• Roles of muscle for movement

  • Extensor
  • Flexor
• Types of exercise for muscles

  • Aerobic Exercise
  • Anaerobic Exercise
• Central Nervous System

  Center for all nerve processes
• Peripheral Nervous System


  Relays information to the organs, arms, legs, fingers, and different parts of the body
• Divisions of the Nervous System


  • Somatic
  • Autonomic

  
• Autonomic Nervous System Divisions

  • Sympathetic Division
  • Parasympathetic Division
• Sympathetic Division

  "Fight or Flight"
• Parasympathetic Division

  "Rest and Relax"
• Stages of Information Processing

  1. Sensory Input - Detection of environmental stimuli

  2. Integration - Interpretation of sensory information

  3. Motor OutPut - Initiation of actions
• Organs of the Nervous System

  • brain
  • Spinal chord
  • nuerons
• Stages of Information Processing

  • Sensory Neuron
  • Interneuron
  • Motor Neuron
• The cerebellum, located at the back of the skull, coordinates voluntary movements and maintains posture and balance.
• parts of the brain

  -Cerebrum

  -Cerebellum

  -Brain Stem
• Cerebum - Touch Vision, Hearing, speech, reasoning, emotions, learining & fine control movements
• Cerebellum - Coordination of movement, Posture, Balance
• Brain stem - Controls vital functions such as breathing, heart rate, body temperature, blood pressure, swallowing, digestion, sleep, consciousness, alertness, and arousal
