eye-hand co-ordination and arm movement
Wernicke’s area that is responsible for matching written words with
the sound of spoken speech.
Occipital Lobe
Controls vision and recognition
Limbic Lobe
Makes up the limbic system
Limbic System
Regulates emotion and memory.
It directly connects the lower and higher
brain functions
Thalamus
Thalamus means “inner room” in Greek,
as it sits deep in the brain at the top of
the brainstem.
The thalamus is called the gateway to
the cerebral cortex, as nearly all
sensory inputs pass through it to the
higher levels of the brain.
Hypothalamus
The hypothalamus sits under the thalamus at
the top of the brainstem. Although the
hypothalamus is small, it controls many critical
bodily functions:
• Controls autonomic nervous system
• Center for emotional response and
behavior
• Regulates body temperature
• Regulates food intake
• Regulates water balance and thirst The hypothalamus is
• Controls sleep-wake cycles shaded blue. The pituitary
gland extends from the
• Controls endocrine system hypothalamus.
The Ventricles
The ventricles are a complex
series of spaces and tunnels
through the center of the brain.
The ventricles secrete
cerebrospinal fluid, which
suspends the brain in the skull.
The ventricles also provide a
route for chemical messengers
that are widely distributed through
the central nervous system.

Cerebellum (Midbrain)
The cerebellum is connected to the
brainstem, and is the center for
body movement and balance.
The Pons
The pons is the rounded
brainstem region between the
midbrain and the medulla
oblongata. In fact, pons means
“bridge” in Latin.
The main function of the pons is
to connect the cerebellum to the
rest of the brain and to modify the
respiratory output of the medulla.
The pons is the origin of several
cranial nerves.
The Medulla Oblongata
(Hindbrain)
The medulla oblongata merges
seamlessly with the spinal cord and
creates the base of the brainstem.
The medulla is primarily a control
center for vital involuntary reflexes
such as swallowing, vomiting,
sneezing, coughing, and regulation of
cardiovascular and respiratory activity.
The medulla is also the origin of many
cranial nerves.
