Cerebrum: 
The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action.

Cerebellum: 
The cerebellum is associated with regulation and coordination of movement, posture, and balance.

Limbic system:

The limbic system, also called the emotional brain", is found is found in the cerebrum. Like the cerebellum, evolutionary the structure is rather old.

Thalamus:

 The structure has sensory and motor functions. Almost all sensory information enters this structure where neurons send that information to the overlying cortex.

Motor cortex:
sends signals controlling body movements

Amygdala:
involved in memory, emotion, and fear.

Hippocampus:
 This part of the brain is responsible for  learning and memory.

Midbrain:

It is involved in functions such as vision, hearing, eye movement, and body movement.

Pons:
Responsible for facial expressions

Medulla Oblongata:
Responsible for involuntary functions, such as breathing and heart rate

Hypothalamus:
controls body temperature, thirst, hunger , endocrine system and hunger

Hemispheres:
Left- responsible for logic and sequential task
Right-responsible for spatial and creative tasks

Broca's area
responsible for controlling muscle that produce speech
 
Frontal lobe:
Concerned with reasoning, planning, parts of speech and movement (motor cortex), emotions, and problem-solving.
 
Parietal lobe:
Concerned with perception of stimuli such as touch, pressure, temperature and pain.
 
Temporal Lobe:
responsible for you being able to understand what you re hearing
 
Occipital lobe:
Concerned with many aspects of vision.
