Definition
neural network :telephone_receiver: that coordinate :check: voluntary and :green_cross: involuntary actions between different body parts :hand: :poultry_leg: :panda_face: :muscle:
Invertebrate

-
Available in flatworm, higher invertebrates
Vertebrate
-
2 components
Central Nervous System (CNS)
-
-
Peripheral Nervous System (PNS)
-
Role: Carries sensory information to CNS; send motor commands to muscle :muscle::skin-tone-5: and glands

-
NEURON
- structural and functional unit of nervous system
- communicate through nerve impulse
- 3 major parts: :!: dendrites :!!: Cell body :!?: Axon
