Week 7 Agenda
Peripheral Nervous System (branching out, toward the sides) nerves Central Nervous System Brain Spinal Cord 2 Divisions of the N.S.
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
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
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
