Front (Question)

Neuraxis

Back (Answer)

Central axis of nervous system - line going down the body

#8

What are the two references to the neuroaxis

Back (Answer)

Ipsilateral - on same side, left arm is ipsilateral to left leg Contralateral - on oppsoite side - e.g hempispheres control oppositie sides of body

Perpendicular to ground, parralel to neuraxis - side on

#12
Front (Question)

What are the 3 regions of the frontal lobe?

Back (Answer)

• Prefrontal cortex • Primary Motor cortex • Motor association cortex

#13
Front (Question)

Define the PFC

Back (Answer)

Very Front bit of frontal lobe - complex cognitivie behaviours, e.g. executive functioning (planning etc), personality

#14
Front (Question)

Define the primary motor cortex

Back (Answer)

Movement activates msucles via motor neurons

#15
Front (Question)

Define the motor association cortex

Back (Answer)

Intiation of movement - includes pre-motor cortex and supplementary motor cortex

#16
Front (Question)

What year was Phineas Gage and what did it tell us?

Back (Answer)

1848 - that personality traits are in pfc

#17
Front (Question)

What is the cerebral cortex

Back (Answer)

outer layer of brain - responsible for many higher order functions

Back (Answer)

• Gyrus (bulges) • Sulcus (small grooves) • Fissure (large prominent grooves)

#19
Front (Question)

What are the 2 layres of the cerebral cortex?

Back (Answer)

Outer layer = grey matter - cell odies, dendrites, glia Inner layer - white matter - myelinated axons - permits communication between areas of the brain

#20
