i have problem in CNS topic

1 cerebrum and cerebral cortex name of same part of brain

or

name of two different parts?

what are the names of parts of mid brain?

difference between cerebrum and cerebral cortex,,,

The Cerebrum is the largest part of the brain consisting of the four lobes of the brain. These are the parietal lobe, occipital lobe, frontal lobe, and the temporal lobe. Each lobe carries many different responsibilities. A few of these are as follows: Frontal lobe- reasoning, planning, emotions, speech, and movements. Temporal Lobe- memory, speach, auditory stimuli, and perception and recognition. The parietal lobe-orientation, recognition, stimuli. The Occipital Lobe-visual processing. The Cerebral Cortex is the material filling the grooves seen in brain images. It is responsible for many different senses such as memory, attention, awareness, thought, language, and consciousness. A lot of these movements are associated with the cerebral cortex are voluntary, but not all are.

parts of midbrain.....

these are medulla oblongata, pones and reticular formation

[B]Cerebrum:[/B]

The Cerebrum is part of the fore-brain that includes the cerebral cortex. It is the largest part of the human brain, consisting of the four lobes of the brain.Each lobe carries many different responsibilities :

1.Frontal lobe- reasoning, planning, emotions, speech, and movements
2.Parietal lobe-orientation, recognition, stimuli
3.Occipital lobe-visual processing
4.Temporal lobe-memory, speech, auditory stimuli, and perception and recognition.


[B]Cerebral Cortex:[/B]

The cerebral cortex is the outer outer layer of gray matter in the cerebrum.It consists mainly of neuronal cell bodies and dendrites in humans; associated with higher functions, including language and abstract thought.

[B]Midbrain (mesencephalon):[/B]

The midbrain is located below the cerebral cortex, and above the hindbrain . It comprises :
