  5. Week 7 Agenda

  6. Peripheral Nervous System (branching out, toward the sides) nerves Central Nervous System Brain Spinal Cord 2 Divisions of the N.S.

  7. 3 Parts: Brain Cerebrum (thinking, reasoning, sensing) Cerebellum (routine motion, muscle coordination) Brain stem & medulla (involuntary actions: breathing, heart beat) Spinal cord Brings messages to and from the brain, travels through the vertebrae for protection If severed you are paralyzed from there down Nerves Motor Neurons (brain  muscles to move) Interneurons (from one neuron to another) Sensory Neurons (body  brain to sense: touch, smell, sound, taste, sight) One nerve cell = neuron, many neurons = nerve Nervous System

  8. Control Systems Pre-write

  9. Endocrine System • Signals are hormonesthat travel through the blood Ex: growth hormone, adrenaline • They fit like a lock and key with targetcells in the organ they will affect • Mmostact slowly over a long period of time • Glandsproduce hormones • Pituitary is the master gland • Hypothalamus in brain connects the Nervous and Endocrine Systems

  10. Immune System • Fights pathogens due to foreign antigens Bacteria, viruses, fungus • First line of defense = barriers • Skin*, saliva, tears • Nose hairs, mucus • Second line of defense=white blood cells • Macrophages “eat” pathogens • WBCs can produce antibodies to kill pathogens
