Cranial Contents Flashcards
Brainstem omposed of
Medulla, pons, and midbrain
Posterior aspect of BS
Cerebellum
DIencephalon composed of
Thalamus, hypothalamus, and epithalamus
Cerebrum is composed of
2 hemispheres
Superior
Each cerebral hemisphere composed of
Cerebral cortex and subcortical areas
Pituitary gland associated with
Hypothalamus
PIneal gland associated with
Epithalamus
Cerebrum divised into hemispheres by
Longitudinal fissure
Sulci vs. gyri
Gyri - ridges
Sulci - crevices
Central sulcus separates
Frontal and parietal lobe
Lateral sulcus separates
Frontal/parietal from temporal
Corpus callosum
White matter…communicates between left and right
Cingulate gyrus
Limbic lobe…emotions
Frontal lobe functions
Motor, executive functions
Parietal lobe function
Somatosensory
Temporal lobe function
Auditory
Learning and memory
Occipital lobe function
Visual areas
Insular lobe found inside
Lateral sulcus
Neurocranium bones
Frontal, ethmoid, sphenoid, temporal, parietal, occipital
Calvvarium
Top part of neurocranium where bones are flat
Anterior cranial fossa boundary
Frontal bone and lesser sphenoid wing
MIddle cranial fossa
Lesser sphenoid wing
Petrous ridge of temporal
POsterior cranial fossa location
Posterior to petrous ridge of temporal
Anterior cranial fossa contents
Frontal lobe
Olfactory bulbs
Middle cranial fossa contents
Temporal lobe
Cavernous sinus and CNs
Internal carotid arteries
Posterior cranial fossa contetns
Cerebellum and brainstem
Lateral ventricle
C-shaped in each hemisphere
3rd ventricle
Mid-sag between L and R thalamus
4th ventricle
Posterior to BS
Choiroid plexus
Produces CSF
Capillaries of choroid plesxus are
Fenestrated
CHoroid epithelial cellscontain
Tight junctions
CSF flows from ventricles to the
Subarachnoid space
