located in the center of the cell. Surrounded by a membrane that keeps all the chromosomes inside
Nucleus
Genetic material is composed of…
DNA
A long thread of DNA wrapped in histones (POSITIVELY CHARGED PROTEINS)
Chromosomes

Plays an important role in communication between neurons. It is the producer of myelin and aids in blood-brain barrier functions ect.
Glial cells
DANGS
Dopamine
Acetylcholine
Norepinephrine
Serotonin
Also known as cell body. contains the nucleus and other compounds needed for cell maintenance and function.
Soma
A long projection that extends form a neuron’s soma. Transmits electrical impulses
Axon
fingerlike projections from a neuron’s soma. recieves incoming messages form other neurons,
Dendrites
fatty substance wrapped around axons that serve as its insulator
Myelin Sheath
Three types of Neurons
Sensory, Motor, Mirror
Arousal, Positive Emotions
