Subdivisions of Brain

Frontal Lobe

Contains premotor and primary motor areas.

Frontal Lobe

Contains Broca’s area for language

Parietal lobe

Sense of touch is located here.

Parietal lobe

Higher-level processes for math and problem solving are also located here.

Temporal lobe

Sense of hearing is located here.

Temporal lobe

Contains Wernicke’s area for language

Occipital lobe

Sense of vision is located here.

Insula

Not much is known.

Thalamus

Switching station for incoming sensory messages and sends message to appropriate lobe of the cerebrum

Hypothalamus

Monitoring station for maintaining homeostasis, regulates temperature

and performs autonomic and endocrine functions

Midbrain

Appears as a hook and has colliculi for vision and hearing.

Pons

Appears as a bulge between the midbrain and the cerebellum and serves as a bridge to the cerebellum for efferent motor messages

Medulla oblongata

Most inferior part of the brainstem.

Medulla oblongata

Motor messages cross sides at the pyramids.

Medulla oblongata

Contains centers to regulate heart rate, blood pressure, respiratory rate, and blood vessel diameter

Reticular formation

Groups of cell bodies located throughout the brainstem

Reticular formation

Determines if sensory messages will be consciously perceived by the

cerebrum.

Reticular formation

Responsible for sleep-wake cycle

Brainstem

Located in the cranial cavity inferior to the diencephalon and anterior to the cerebellum

Brainstem

All parts include tracts (bundles of nerve fibers) of neurons traveling to and from the spinal cord.

Diencephalon

Located deep to the cerebrum

Cerebrum

Largest subdivision, divided into two hemispheres

Cerebrum

Characterized by gyri and sulci
