Overview of the brain Flashcards
Name the parts of the corpus callosum
rostrum, genu, body, splenium
where does the frontal lobe lie?
anterior cranial fossa
What lies in the middle cranial fossa?
temporal lobe and parietal lobe
where is the insular lobe
deep in the lateral fissure, overlapped
what is the limbic lobe
a functional lobe, cingulate gyrus and parahippocampal gyrus, emotions and intellect
where is brocca’s speech area
ONLY the L hemisphere of frontal lobe
primary motor area
precentral gyrus of frontal lobe
function of prefrontal cortex
personality and judgement
primary sensory area
postcenrtal gyrus of parietal lobe
where is the hippocampus found
deep in the parahippocampal gyrus
where is the amygdala found
deep to the uncus, the medial tip of parahippocampal gyrus
where is the primary auditory area
superior temporal gyrus of temporal lobe
where is the primary visual cortex
on either side of the calcarine fissure in the occipital lobe
what does the diencephalon contain
the hypothalamus, thalamus, epithalamus, subthalamus
what is the function of the thalamus
integration and relay center for sensory, motor, and limbic systems
what is the function of the hypothalamus
control of ANS and endocrine systems, connections with limbic
what is the function of the subthalamus
motor function related to basal ganglia
What structures are developed in a C shape
hemispheres, lateral ventricle, caudate nucleus, corpus callosum
the globus pallidus and putamen are found
medial and lateral in the basal ganglia
where do axons of the internal capsule in the diencephalon run
to and from the cortex
what do each of the cerebellar peduncles relate to?
superior- midbrain
middle- pons
interior- medulla
which CN are related to the midbrain
CN III, CN IV
which CN are related to the pons
CN V
which CN are related to the pontomedullary junction
CN VI, CNVII, CN VIII
which CN are related to the medulla
CN IX- CN XII
what is the medulla continuous with
the spinal cord
where is the coronal suture found
between the frontal and parietal bones
where is the sagittal suture found
between the parietal bones
where is the bregman suture found
where the sagittal and coronal sutures meet
where is the lambdoid suture found
between the parietal and occipital bones
where is the lambda suture found
where the sagittal and lambdoid sutures meet
what is the boundary between anterior and middle cranial fossa
edge of lesser wing of sphenoid
what is the boundary between middle and posterior cranial fossa
ridge in the petrous portion of the temporal bone
what does the anterior cranial fossa contain
the frontal lobe, olfactory nerve
what does the middle cranial fossa contain
temporal lobe, parietal lobe, CN II- VI exit, ICA enters
what does the posterior cranial fossa contain
occipital lobe, brainstem, cerebellum, CN VII-XII exit, medulla (continuous with SC), vertebral a. and spinal CN XI enter foramen magnum
