UPDATED ACTUAL Exam Questions and
CORRECT Answers
List the brain areas present in the "precentral" area of the frontal lobe - CORRECT
ANSWER - -Primary motor area (Area 4)
Precentral Gyrus and Ant. part of paracentral lobe
-Premotor area (Area 6)
In front of area 4 (in sup, mid, inf. frontal gyri) it extends on med surface of cerebral hemisphere
-Frontal eye field (Area 8)
In front of area 6 (in sup & middle frontal gyri)
Part of frontal eye field responsible for voluntarily conjugate eye movements, it's stimulation
leads to contralateral deviation of both eyes
-Broca's Area
In the pars triangularis (area 45) and the pars opecularis (area 44) of the inf frontal gyrus. Present
in dominant hemisphere (usually L)
-Supplementary Motor area (MII)
On the medial surface of hemisphere within the medial frontal gyrus
What are the areas in the parietal lobe? - CORRECT ANSWER - Role: Senses and spatial
awareness (proprioception)
Areas:
Primary somatosensory cortex (postcentral gyrus): Involved with processing of tactile and
proprioceptive info
Second somatosensory area (SII): In the sup lip of post ramus of lateral sulcus behind the central
sulcus
Somatosensory association cortex: Assists with integration and interpretation of sensations
relative to body position and orientation in space. Maybe vison-motor coordination
Primary Gustatory Cortex: Primary site involved with interpretation of sensation of taste
,What are the three speech centers and their functions? - CORRECT ANSWER - Broca's
area: Anterior to Wernicke's, involved in the production of speech
Wernicke's area: involved in the interpretation of speech
Superior speech center (in supplementary motor area MII in medial frontal gyrus)
List the areas in the temporal lobe, their site and function: - CORRECT ANSWER -
Primary auditory area A1 (Area 41, 42: Inf lip of lateral sulcus and adjacent part of sup temporal
gyrus
Receives the auditory radiation from the MGB bringing impulses from both ears (here auditory
stimuli reach consciousness)
Secondary Auditory area AII (Area 22): Sup temporal gyrus around the primary auditory area.
Understands the meaning of auditory stimuli by associating with past experiences
Vestibular Area: Sup temporal gyrus close to primary auditory area. Receives information about
head position and movements from vestibular nuclei after relaying on the VPMN of thalamus
Part of Wernicke's (facial recognition area): On interior surface of temporal and occipital lobes
Olfactory areas (piriform cortex)
-Primary olfactory area in 3 regions=Uncus + part of amygdala + apex of insula
Secondary olfactory area: in para-hippocampal gyrus which also contains centers of memory and
learning
List the areas in the Occipital lobe - CORRECT ANSWER - Primary visual cortex:
Primary area of the brain responsible for sight- recognition of size, colour, light, motion,
dimensions etc.
Visual association area: Interprets info for acquired via primary visual cortex
, Arcuate Fasciculus: White matter tract connecting Broca's area and Wernicke's Area through
temporal, parietal and frontal lobes
Allows for coordinated, comprehensible speech
What structures constitute the limbic system? - CORRECT ANSWER - Primarily
responsible for emotional life, and has to do with the formation of memories
Hypothalamus, Hippocampus, Amygdala, olfactory bulbs and several other nearby areas.
Name the 5 nuclei that make up the basal ganglia - CORRECT ANSWER - Group of
nuclei (gray matter) located under each cerebral hemisphere
Control Voluntary movements, functionally related to substantia nigra & Subthalamic nucleus
-Caudate Nucleus
-Putamen
-Globus Pallidus in the Diencephalon
-Subthalamic nucleus in the Rostral Midbrain
-Substantia Nigra
What is the blood supply of the basal ganglion? - CORRECT ANSWER - Anterior
Cerebral
Middle Cerebral
Anterior Choroidal
What is the internal capsule, parts and its blood supply? - CORRECT ANSWER - Funnel
of fibers from the Corona Radiata converging in the subcortical areas
-Anterior limb, genu, posterior limb, retrolenticular and sublenticular limb
runs between 3 masses of grey matter: Thalamus & caudate nucleus (medially) and lentiform
nucleus (laterally)
