UPDATED EXAM SOLUTIONS.
Forebrain - correct answer- The anterior part
of the brain, including the cerebral
hemispheres, thalamus, and hypothalamus.
Midbrain - correct answer- The middle part of
the brain, located between the forebrain and
hindbrain.
Hindbrain - correct answer- The posterior part
of the brain, including the cerebellum, pons,
and medulla oblongata.
Gray matter - correct answer- The darker
tissue of the brain and spinal cord,
consisting mainly of nerve cell bodies and
dendrites.
White matter - correct answer- The lighter
tissue of the brain and spinal cord,
consisting mainly of myelinated nerve fibers.

Meninges - correct answer- The three
protective membranes that surround the brain
and spinal cord: dura mater, arachnoid mater,
and pia mater.
Cerebrospinal fluid - correct answer- The
clear, colorless fluid that surrounds and
cushions the brain and spinal cord.
Ventricles - correct answer- The
interconnected cavities within the brain that
are filled with cerebrospinal fluid.
Medulla Oblongata - correct answer- The
lowermost part of the brainstem, responsible
for controlling vital functions such as
breathing and heart rate.
Pons - correct answer- A structure in the
brainstem that connects the cerebrum with the
cerebellum and is involved in regulating sleep
and arousal.

Midbrain (mesencephalon) - correct answer- The
middle part of the brainstem, involved in
sensory and motor functions, as well as the
regulation of sleep and wakefulness.
Tectum - correct answer- The dorsal (roof)
part of the midbrain, involved in visual and
auditory reflexes.
Tegmentum - correct answer- The ventral
(floor) part of the midbrain, involved in
motor control and sensory processing.
Reticular formation - correct answer- A
network of neurons in the brainstem that
regulates arousal and attention. functional
group of nuclei.
Cerebellum - correct answer- A structure
located at the back of the brain, responsible
for coordinating voluntary movements, balance,
and posture.
