Primary visual area
frontal lobe is the____ and is connected to the parietal lobe via the_____
precentral gyrus
central sulcus
parietal lobe is the _____
postcentral gyrus
temporal lobe is connected to the frontal lobe via the _____
lateral cerebral sulcus
the ocipital lobe is connected to the parietal lobe via the______
parieto-occipital sulcus
where is the insula located
within the lateral cerebral sulcus deep to parietal frontal and temporal lobes
what are the five sensory areas of the cerebral cortex
primary somatosensory area
primary visual area
primary auditory area
primary gustatory area
primary olfactory area
what is the function and location of the somatosensory area
located in the post central gyrus
function impulses for touch proprioception, pain, itching, tickle, thermal sensation
location of the primary visual area
posterior end of the occipital lobe
location of the primary auditory area
superior part of the temporal lobe
location of the primary gustatory area
the base of the postcentral gyrus
location of the olfactory area
medial aspect of the temporal lobe
what are the two motor areas
the primary motor area and the Broca’s speech area
location and function of the brocas area
location- frontal cortex
function-coordinated contraction of muscles involved in speech
seven association areas
somatosensory association area
prefrontal cortex
visual association area
auditory association area
common integrative area
premotor area
wernickes area
location and function of the somatosensory association area
location- posterior to the primary somatosensory area
function-determination of shape,texture, orientation, and relations of the parts of the objects
location and function of the prefrontal cortex
location-anterior part of the frontal lobe
function- personality features, intellect, complex learning abilities, reasoning, planning, initiative, judgement, foresight, recall of information
location and function of the visual association area
location- occipital lobe
function- recognition and evaluation of the visual perceptions
location and function of the auditory association area
location-inferior posterior to the primary auditory area
function- recognition of auditory perception
location and function of the common integrative area
location close to the somatosensory, visual and auditory area
function- receives and integrates sensory impulses and interpretations from different areas
location and function of the premotor area
location- anterior to primary motor area
function- complex learned motor activity patterns
location and function of the Wernicke’s area
location- temporal and parietal lobes
function- interprets the meaning of speech by recognising spoken words
what surrounds the diencephalon,
what does it consist of,
what does it enclose
surrounded by the cerebral hemispheres, superior to the midbrain
consists of the thalamus, hypothalamus, epithalamus
encloses the third ventricle
what does the thalamus consist of
what is its role
paired oval masses of grey matter with tracts of white matter, 7 major groups of nuclei
role- major relay station for sensory impulses, motor function, autonomic activities, Maintenace of consciousness
what does the hypothalamus consist of
what is its role
consists of several nuclei arranged in four regions
role- controls and integrates activities of the autonomic nervous system Eg hormones, body temperature, emotional+behavioural patterns
what does the epithalamus contain, where is that located and what does it control
contains the pineal gland, located in the posterior extremity of the 3rd ventricle
controls- release of melatonin and habenular nuclei
location and function of the cerebellum
location- posterior and inferior aspect of the cranial cavity
function- evaluate movement, regulates posture and balance
what does the cerebellum consist of
cortex folded into folia, which contains white matter which contains cerebellar nuclei
what are the hemispheres of the cerebellum connected by and what are the lobes of the cerebellum
hemispheres are connected by vermis
lobes are, anterior, posterior, flocculo-nodular
layers of the cerebellar cortex
molecular layer
purkinje cell layer
granular cell layer
three main parts of the brainstem
midbrain
pons
medulla oblongata
what does the midbrain connect
what does the anterior part contain+role
what does the posterior part contain and role
connects- 3rd and 4th venticles
anterior part contains- cerebral peduncles which share motor impulses
posterior part contains-superior and inferior colliculi, role visual reflexes Eg getting startled
pons-location+contains+made of+two regions
location- midbrain and medulla
contains 4th ventricle
made of tracts and nuclei
regions- ventral, dorsal
function of the ventral region of pons and components of the dorsal region of pons
ventral region- relay station for white matter tracts
dorsal region- ascending sensory and descending motor tracts, cranial nerves nuclei
location and what does white matter in the medulla oblongata contain
location-between the pons and spinal cord
white matter contains sensory and motor tracts, two pyramids and olives
what is the function of the grey matter in the medulla oblongata
vital functions Eg cardiovascular centre, respiratory area, reflexes for vomiting, sneezing, coughing
cranial nerves
function of the ascending sensory tract and descending motor tract
ascending sensory-maintain consciousness
descending motor tract- regulation of resting muscle tone
