Unit2 the body

  1. 1. The musculoskeletal system Consists of skeleton Muscular system Both system work together to make the body move. The skeleton consists of all the bones in the body. The muscular system consists of al the muscles in the body. The skeleton: -It supports the body - It enables the movement -It protects delicate organs such as heart, lungs and brain. The muscular system: -Enables the body to move -Gives the body its shape -Protects the organs such as the liver
  2. 2. • Fixed joints, such us the skull. skull • Movable joints, such us knee or elbow. elbow hip • Gliding joints, such us between vertebrae. vertebrae
  3. 3. Femur Cartilage Femur Cartilage Ligament Tibia Tibia The ends of the bones are covered with flexible tissue called cartilage. Fibula The bones of a joint are connected by strong elastic tissues called ligaments.
  4. 4. Write the words of each sentence in the correct order to make sense: 1.body/ supports/ the/ the/ skeleton 2. meet/ places/ bones/ two/ joints/ where/ are/ the 3. ends/ the/ of/ cartilage/ covers/ bones/ the 4. flexible/ cartilage/ tissue/ is 5. elastic/ strong/ ligaments/ are/ tissue
  5. 5. Muscles can change in length: - When they contract, they become shorter and thicker. - When they relax, they return to their original length and thickness. tendon tendon Relaxed muscle Contracted muscle Muscle contraction
  6. 6. Tissues called tendons connect muscles to bones. Body movement occurs at movable joints. Two muscles are used in each movement. These muscles are called antagonistic because the perform opposite actions. When one muscle contracts, the other relaxes. Arms bend at the elbow with a flexing movement. They straighten with an extending movement. Flexing movement Extending movement The biceps relaxes The biceps contracts The triceps contracts The triceps relaxes The arm bends The arm straightens
  7. 7. Decide if the following sentences are true or false. If they are false, correct them. •When muscles contract, they become longer T/F •When muscles relax, they return to their original length and thickness T / F •Tendons connect the bones of a joint T/F •Antagonistic muscles perform the same actions T / F •Arms bend at the elbow with a flexing movement T / F
  8. 8. The nervous system sends and receives information. It coordinates the functions of internal organs. And it also coordinates systems like the digestive system. The central nervous system consists of Brain Spinal cord This system receives information, interprets it and decide on a response. The peripherial nervous system consists on nerves. It transmits information from the sense organs to the central nervous system and from the central nervous system to other organs.
  9. 9. These are the result of decisions The cerebrum controls voluntary movements The brain stem regulates internal organs. The central nervous system The brain has got three parts: The cerebellum coordinates movements and maintains balances. The spinal cord controls reflex movements These are involuntary movements in response to external stimuli.
  10. 10. Neurons are the principal cells of the nervous system. They receive and transmit information. They are grouped together to form nerves.
  11. 11. Read the following definitions and write the corresponding words: 1.This part of the brain controls voluntary movements. 2.This part of the brain coordinates movements and maintains the balance. 3.This part of the brain regulates internal organs. 4.These are the principal celss of the nervousn system. 5.These are involuntary movements in response to external stimuli. CEREBELLUM REFLEX MOVEMENTS NEURONS BRAIN STEM CEREBRUM
  12. 12. Beating of the heart Involuntary muscles Such us To control and coornidate controls Body´s Internal process Such us Endocrine system Digestion of the food
  13. 13. Involuntary muscles They work automatically. We cannot control them with our decisions. The body needs involuntary muscles in order to function correctly.
  14. 14. GROWTH REPRODUCTION Responsible for Functions such as The endocrine system Consists of Endoncrine Glands Thyroid gland Pancreas Enables the body to absorb nutrients Controls the amount of sugar in the bloodstream They secrete substances called hormones into the bloodstream Ovaries and testes Pituitary glands Responsible for reproduction Coordinates endocrine glands and also produces growth hormone.
  15. 15. Project: measuring your own temperature Human body temperatures vary due to an individual´s metabolism, the time of the day and the part of the body where we measure. Normal body temperatures range betwee 36,6º and 37.3º - When you have a very high temperature, what does it mean?   Data             Time 2011.10.24             8:00 36,2º             22:00 37º
