Nervous System - Coggle Diagram

- - - - Arachnoid(middle)
        
        sub-arachnoid space: Contains Cerebrospinal fluid, made up of water, minerals, glucose, proteins and wastes
        
        Functions:
        Maintains constant cranial pressure
        Transports nutrients and chemicals; removes waste
        Protects and absorbs mechanical shock, jerk
      - pia mater(inner)
      - Dura Mater(outer)
    - - White matter(Outer layer): axons of nerve cells
      - Grey matter(Inner layer): Cell Bodies, Dendrites, synapses, axon terminals
    - - Function:
        Helps to control involuntary movement in head, neck, body
        Helps to control pupil movement and size of eye lens
        Regulation of feelings
    - - Cerebellum
        
        Second largest part of the brain
        Controls the movement of muscles
        Helps in balancing and maintaining posture
        Damage can lead to paralysis
      - Medulla Oblongota
        
        Lowest part of the brain stem
        Emerges from Foramen Magnum
        Regulates respiration, circulation, heart function
        Enables systole and diastole in the heart
        Controls the peristalsis
        Regulates secretion of hormones and digestive juices
        Acts as a center for coughing, sneezing, swallowing and vomiting
      - Pons Varoli
        
        Acts as relay station between medulla and rest of the body
        Regulates Breathing and Respiration
        Regulates chewing and swallowing
        Damage can cause insomnia and problems with swallowing or chewing
    - - Cerebrum
        
        Largest part of the brain
        Covered by cerebral cortex
        Contains right and left hemisphere, separated by corpus callosum
        Damage cause loss of senses, memory, skill or even coma
      - Olfatory Lobes
        
        Two club-shaped structure
        Helps in sense of smell
