nuero 1 - general principles Flashcards
lobes of the cerebral hemispheres
frontal parietal occipital temporal insula
gyri of the occipital lobes
superior
lateral
inferior
neurons consist of
cell body, dendrites and an axon
6 layers f the cerebral cortex neurons
molecular layer external granule cell layer external pyramidal cell layer internal granule cell layer internal pyrimidal layer multiform layer
how do the appearance of layers differ
appearance of layers differs accross the cerebraal cortex
types of neurons
glial cells of CNS
oligodendrocytes astrocytes microglia edendymal cells radial glia
glial cells of PNS
neurlemmocytes (schwaan) cells
satellites cells
enteric glia cells
grey matter is
cell bodies, soma
surface of the cerebral hemisphere
brainstem nuclei
center of the spinal cord
white matter is
cell prcesses, axons (myelinated)
corpuc callosum
internal capsule
what goes in the anterior cranial fossa
frontal lobe
what goes in the middle cranial fossa
temporal lobe
what goes in the posterior cranial fossa
brainstem and cerebellum
foramen magnum
where the medulla of the brainstem becomes the spinal cord
dura mater
tough, fibrous membranes
2 components of the dura mater
flax cerebri
tentorium cerebelli
falx cerebri
seperates the cerebrum
tentorium cerebelli
tent that seperates the cerebellum
arachnod mater
soft translucent, full of veins
subarachnoid space contains
CSF produced from the choroid plexus
pia mater
microscopically small and high vascular
superficial veins are in the
subarachnoid space
deep veins are in the
internal structures of the forebrain
list of dural venous sinuses
superior sagital inferior sagital straight transverse confluence of sinuses
location of dural sinuses
