Science test 1

• Epinephrine


  • Increases heart rate
  • Opens air passages allowing more oxygen to go into the body
  • Gives insulin secretion causing glucose to remain in the blood
• When core temp drops

  Body initiates mechanisms increasing heat control
• Ribosome


  • Cellular machine responsible for making proteins
  • Synthesizing proteins
• Cerebellum


  The back of the brain between the cerebrum and brain, it coordinates movement and balance
• Cerebrum


  The largest part of the brain that handles thoughts and conscious, it controls the functioning muscles
• Brain stem


  The structure that connects the cerebum to the spinal cord and cerebellum, responsible for breathing, blood pressure, heart rate
• Hypothalamus


  Produces hormones, keeping the body stable called homeostasis
• Regulating the body temperature

  1. Sweat glands: As water in the sweat evaporates the surface of the skin cools

  2. Body muscles: By generating heat
• Homeostasis


  Keeping the body at a stable balance among all the body systems needed to survive
• Synapse


  • The space between 2 neurons
  • Where information is passed from one neuron to the next
• Myelin sheath


  Allows electrical impulses to transmit quickly and efficiently well as nerve cells
• White matter in the central nervous system
• Grey matter in central nervous system
• Functions in the brain

  • Cerebrum: Initiates coordination in movement and regulating temperature
  • Cerebellum: Coordinating movement and balance
  • Medulla: Manages the heart, circulation and breathing
