anatomy of the nervous system 1 Flashcards
where is the primary motor cortex?
precentral gyrus
what does the central sulcus divide?
frontal from parietal lobe
where is the primary sensory cortex?
postcentral gyrus
what are the 3 types of fibres in white matter?
- association
- commissural
- projection
what are association fibres and name 2
- connect one area of cortex with another in the SAME hemisphere
- superior longitudinal fasiculus
- inferior longitudinal fasiculus
what are commisural fibres and name 2
= connect the cortex of one hemisphere with the opposite hemisphere
- corpus callosum
- anterior commissure
what are projection fibres and name 2
= connect the cortex with subcortical regions (thalamus, basal ganglia, brainstem and spinal cord)
- corona radiata
- internal capsule
what is the basal ganglia and what does it consist of?
= a collection of nuclei within the cerebral hemisphere involved in the control of movement and posture
- caudate nucleus, putamen, globus pallidus
- involved in parkinson’s disease
what is the diencephalon?
what is the thalamus for and what is it either side of?
- either side of 3rd ventricle
- body’s sensory information relay centre
what does the brainstem consist of?
midbrain + pons + medulla
ventral and dorsal surface of midbrain
ventral and dorsal surface of the medulla
transverse section of medulla
what is the cerebellum used for?
- control of movement
- balance
- posture
what is the denticulate ligament?
a bit of pia mater attached to the spinal cord at the side
what would a cross section of the spinal cord look like?
spinal cord transverse section - label
