Expert Solution
Brain is formed by cerebral hemisphere that are separated by
longitudinal fissure. Cerebral hemisphere is divided into left and
right cerebral hemisphere.
Cerebral cortex is the outside layer of the cerebral hemisphere
that is composed of grey matter.
Middle layer of the cerebral hemispheres consist of white
matter.Deep gray matter is present Innermost layer of the cerebral
hemispheres that is composed of basal ganglia.
Right cerebral hemisphere,
Controls the muscles on the left side and receives sensory input
from the left side of the body.
Left cerebral hemisphere,
Controls the muscles on the right side and receives the sensory
input from the right side of the body.
LOBES OF BRAIN
1)Frontal lobes is located at the top,front region of each of
cerebral hemisphere.
Frontal lobe is associated with
movement,intelligence,reasoning,personality,planning,decision
making,judgment,awareness of abilities and limitations,organisation
and mood.
2)Parietal lobe-Located above occipetal lobe and behind frontal
lobe.They are actively involved in
Interpretation of sensory input, understanding of speech and
formulating words to express thought and emotion, and
interpretation of textures and shape.
3)Occipital lobe lobe located in the back of head above
neck
It is involved in integration of eye movements in focusing the
eye,correlation of visual images-and conscious perception of
vision.
4)Temporal lobe located beneath the Sylvain fissure on both
cerebral hemispheres.It is involved in auditory perception and
storage of auditory and visual experiences
Temporal lobe contains hippocampus that is important in formation
of long term memory.It lies in the medial temporal lobe of
brain.
This lobe responsible for speech,behaviour,vision,smell and
emotions etc.
5)The fifth lobe ,insula which separates the cerebrum into
frontal,parietal, and temporal lobes.
Insula is associated in memory,perception of pain and visceral
integration of cardiac responses.
