Nervous system 1 Flashcards
Neuron
神經元:excitable cells that transmit electrical signals for communication via sunapses突觸
(also, the basic functional unit of the nervous system)
neuroglia
神經膠質細胞:function-support & insulate隔離(more numerous than neurons)

what does white matter include?
myelinated有髓的 axon/fibre: nerve fibers or extensions of neurons that are surrounded by a protective covering called myelin

cell body(somas) and dendrites樹突
”有髓軸突“是神經纖維或神經元的延伸,被稱為髓磷脂的保護層包圍
