Lab 1 and 2 Flashcards
CNS=
Brain and spine
brain parts
forebrain=prosencephalon
midbrain= mesencephalon
hindbrain= rhombencephalon
forebrain parts
Telencephalon= cortex
Diencephalon= thalamus and hypothalamus
(and basal ganglia into one of those?)
Hindbrain parts?
metencephalon= pons myelencephalon= medulla
cisterns
- Define
- name them.
large subarachnoid spaces
- Interpeduncular cistern
- quadrigeminal cistern
- cisterna magna
- prepontine cistern
potential spaces
- epidural space
2. subdural space
transverse cuts are made in?
brainstem and spinal cord
Gyri associated with
- primary motor
- primary somatosensory
- hearing
- vision
- emotions and motivation
- precentral
- postcentral
- superior temporal
- calacrine
- cingulate = “limbic lobe”
spinal arteries
anterior vs posterior?
1 anterior= motor
2 posterior= dorsal column
CT scan- bright–> dull colors
Bright= dense
Bone>blood>brain
Blood in ventricles? Blood outside ventricles?
subarachnoid bleed= blood in sucli, but not in ventricles
Nucleus
functional and structural subdivisions in brain
White matter bundles
corpus callosum = callosal fibers
internal capsule = projection fibers
centrum semiovale
stria terminalis
fiber systems in brain (x3)
callosal= connection between hemispheres
association= connect close regions
projection fibers= connection between distant parts of brain. Ex: Internal capsule
cerebellar peduncle
- superior= primary output of cerebellum (carry info to midbrain)
- Middle= input from contralateral cerebral cortex
- inferior- proprioceptive info from ipsilateral body
