What does the hindbrain consist of?

The medulla oblongata, pons, and cerebellum

What is the function of the midbrain?

Integrates sensory signals and orchestrates responses to the signals

What does the forebrain consist of?

The cerebrum, thalamus, and hypothalamus

Regulates breathing, blood pressure, and heart rate

What is the function of the pons?

Transmits signals between forebrain and cerebellum

What is the function of the cerebellum?

Controls balance, movement and coordination

What is the function of the midbrain?

Maintains alertness, sleep wake cycle and motor activities

What is the function of the forebrain?

Contains primary motor sensory cortices

What does the forebrain consist of?

The right hemisphere and left hemisphere

The brain is divided into what four lobes?

What is the function of the frontal lobe?

Responsible for short term memory, working memory and information processing

What is the function of the parietal lobe?

Sensory input and positioning of the body

What is the function of the occipital lobe?

Visual input, processing and output

What is the function of the temporal lobe?

Auditory input, processing and output

What is the cerebral cortex?

a thin layer of grey matter covering the cerebrum

What are the three parts of the brain stem?
