Nervous system, Central nervous system (CNS) - Coggle Diagram

- - - - 2.Transmission of electrical signal from the dendrites to the axion terminals.
        
        3.Nerve impulse gets to the axon terminal.
        
        4.Vesicles breack up.
        
        5.Neurotransmitters are released into the synaptic cleft.
        
        They join to the dendrite membrane of the next neuron.
        
        7.Cycle continues on next neuron.

- - - - Cell body
        
        Contains the nucleus and cytoplasm
      - Dendrites
        
        Conducts impulses toward the cell body
      - Axons
        
        Concucts impulses away from the cell body
        
        Some axons are covered with a myelin sheath
  - - - Transmit information from the receptors to the most important nerve centres.
    - - Transmit the signals from the nerve centres to the effectors organs.
    - - Connect the sensory neurons and the motor neurons. (Found in brain and spinal cord)
- - - - cerebrum
      - Cerebellum
      - brain stem
      - spinal bulb
    - - Bones
        
        Skull

      - Membranes(3)
        
        Meninges
    - - Grey matter
        
        Made of dendrites
        
        Inner part of the spinal cord and the outer part of the cerebrum
      - White matter
        
        Made of axons of neurons covered in myelin
- - - - coordination organ systems
        
        Effectors
        
        Locomotor system or hormones
        
        Nervous system or endocrine system
      - Sensory organs
- - - - Regulates functions such as blood pressure, heartbeat and breathing.
      - Crossing over of the nerves so that the right side of the brain recives information from the left side of the body and vice-versa.
  - - - Regulates sleep, visual and auditory reflexes
      - Helps to select stimuli send to the brain
  - - - Recive information for balance from the iner ear.
      - Co-ordinates motor impulses sent by the brain so that movements are precise
  - - - Responsible for all voluntary activity in the body, including thought.
      - It controls learnt behaviour
      - Higher functions like memory, attention, perceptual awarenes, language, consciousness, learning and intelligence.
