Hindbrain, Midbrain, and Forebrain Quiz

The brain is divided into _ main regions.

• three

• four

Answer explanation

The brain is divided into three main regions. The brain can be divided into three main regions: the hindbrain, midbrain, and forebrain

Each brain region has a distinct role in behaviour and mental processes, functioning in isolation from other brain regions.

• True

• False

Answer explanation

While each brain region has a distinct role in behaviour and mental processes, different brain regions do not operate in isolation. Interaction occurs between different brain regions to enable the processing of information and coordination of activity.

Which of the following brain regions has a role in basic survival functions, including movement, breathing, heart rate, and digestion?

• Hindbrain

• Midbrain

• Forebrain

Answer explanation

The hindbrain and its structures, including the cerebellum, medulla, and pons, have an important role in coordinating basic survival functions, such as movement, breathing, heart rate, and digestion.

The hindbrain contains the ________, which is responsible for calculating and coordinating skeletal muscle movement.

• cerebellum

• cerebrum

Answer explanation

The hindbrain contains the cerebellum, which is responsible for calculating and coordinating skeletal muscle movement.  After receiving information about the position of the body in space and motor commands regarding what movements should be made, the cerebellum then calculates how to move appropriately and communicates this motor information to the skeletal muscles, which then carry out the motor movement.

The midbrain is responsible for (Select all that apply)

• regulating sleep and physiological arousal.

• coordinating sophisticated mental processes, including cognition and perception.

• relaying neural information between the hindbrain and the forebrain, and between structurally higher brain areas and the spinal cord.

Answer explanation

The midbrain is involved in many functions, including regulating sleep and physiological arousal, and relaying neural information to, from, and within the brain. The forebrain is the brain region that is responsible for coordinating sophisticated mental processes.

The reticular formation is exclusively located in the midbrain.

• True

• False

Answer explanation

While the reticular formation is located predominantly in the midbrain, it is not strictly confined to this brain region. It extends along the brainstem and has pathways that project into the hindbrain and forebrain.

The forebrain contains the ___________, which is responsible for filtering sensory information, excluding olfactory information, and relaying this sensory information to structurally higher brain areas.

• hypothalamus

• thalamus

Answer explanation

The forebrain contains the thalamus, which is responsible for filtering sensory information, excluding olfactory information, and relaying this sensory information to higher brain areas.  The role of the thalamus resembles a ‘post office’ to which sensory ‘letters’ are sent from sensory receptors in the body. The thalamus acts as the ‘mail sorter’, filtering these sensory messages and relaying them to the appropriate brain areas for further processing

All regions of the brain are involved in motor movement.

• True

• False

Answer explanation

Every region of the brain contributes to the process of motor movement. The hindbrain contains the cerebellum, which calculates and coordinates skeletal muscle movement. Every motor message is relayed by the midbrain from structurally higher brain areas to the spinal cord. The forebrain initiates voluntary motor movements.

Which of the following sentences is most correct?

• The hindbrain is a brain region that coordinates basic survival functions.

• The hindbrain is a brain region that is involved in body functions.

Which of the following sentences is most correct?

• The midbrain relays neural information within and outside of the brain.

• The midbrain relays neural information within the brain, and between structurally higher brain areas and the spinal cord.
