2 gross brain and spinal cord anatomy Flashcards
what does cortical mean
relating to or consisting of the cerebral cortex
what separates the 2 hemispheres of the telencephalon
falx cerebri
longitudinal fissure
what part of the telencephalon functions to integrate motor and sensory information and serves to allow communication between the 2 hemispheres
corpus callosum (WHITE MATTER)
what is the function of the anterior and posterior paracentral gyri that surround the paracentral lobule
anterior: motor to contralateral lower extremity
posterior: sensory to contralateral lower extremity
what is the function of the cingulate gyrus? and what part of the brain is it located ?
- located in the telencephalon (forebrain)
- functions in memory, learning, and limbic system
what type of matter is the corpus callosum
white matter
what is the function of the frontal lobe
personality
decision making
motor
speech
what makes up the primary motor cortex
precentral gyrus + anterior paracentral gyrus
located in the frontal lobe
what are the 3 parts of the inferior frontal lobe
- pars opercularis (most superior/posterior)
- pars triangularis
- pars orbitalis (most inferior/anterior)
what makes up broccas area
- in frontal lobe, part of the inferior frontal gyrus of the dominant hemisphere (usually left)
1. pars triangularis
2. pars opercularis
what is important about the middle frontal gyrus
location of frontal eye fields
function of the parietal lobe
sensory and association
what makes up wernickes area
*in inferior parietal lobe/ left temporal lobe
[1 and 2 in inferior parietal lobule; 3 in temporal lobe]
1. supramarginal gyrus (around the lateral fissure)
2. angular gyrus (around the superior temporal sulcus)
3. superior temporal gyrus (parts of)
*posterior superior temporal gyrus
function of the temporal lobe
- processing/interpreting of initial auditory stimuli
- memory
- organizing/comprehending language
what makes up the primary auditory cortex
- the superior temporal gyrus and transverse temporal gyrus
function of the occipital lobe
integrate/process visual stimuli
what makes the primary visual cortex
- *gyri around the calcimine sulcus
1. cuneus gyrus
2. lingual gyrus
*on occipital lobe
function of the insular lobe
unclear
parts of the basal ganglia
- caudate nucleus
- globus pallidus (medial)
- putamen (lateral)
- thalamus
- internal capsule
