Terms Flashcards
Axon
Nerve fibres that conduct impulses away from cell body to CNS
Choroid plexus
Network of nerves in the brain that secrete CSF (cerebrospinal fluid)
Dentrite
Receives the information/ stimuli from the neuron
Endoneurium, Epineurium, perineurium
Endoneurium - surrounds nylon sheath of axon
Epineurium - surrounds outside of never
Perineurium - smooth membrane enclosing fascicle of axons
Ganglion
A collection of neuron bodies in the PNS
Gray matter
In spinal cord, outside brain , contains synaps
White matter
Inside brain, outside spinal cord
Consists of tracts
Interneuron
Association neurone CNS
Mylin
Insulating sheath that forms around axons to protect and electrically insulate the transmission of nerve impulses
Neuroglia
Glial cells “nerve glue” supporting neurone
Neuron
“Excitable cells” sense electrical signals and conduct nerve impulses
Neurotransmitter
Hold synaps
Nerve
Bundle of axons
Synaps
Where the axon meets the dentrite of another cell
Ganglia
Cluster of neuron cell bodies
