Biological Influences Flashcards
CAT
Tomography
FMRI
Magnetic imaging-technique used to detect areas of the brain which are involved in emotion
MRI
powerful magnetic fields which compare soft tissue
PET
how an organ or system in the body is working
MEG
Mapping brain activity
Noradrenaline
Human brain and body
Serotonin
Blood platelets and serum
Dopamine
Body
Dendrites
Receive electrical impulses from other cells
EEG
Electrical activity of the brain
Cell body
Contains the nucleus and produces proteins
Nucleus
Control centre of the cell
Stores DNA
Axon
Sends messages to neurons, muscles and glands
Myelin sheath
Protects and insulted the axon and speeds up messages
Shwann cell
Produces the myelin sheath
Node of ranvier
Gap between axons
