What type of tissue makes up the cerebral cortex?
  • The cerebral cortex is composed of gray matter. Gray matter is primarily neuron cell bodies.
  • The cerebrum is involved in higher order functions such as consciousness, personality, and intellect.
  • The corpora quadrigemina are found on the posterior surface of the midbrain. They can be observed by looking into the transverse fissure.
  • The cerebral aqueduct is the narrow passageway that connects the third and fourth ventricles. It can sometimes be observed on a midsagittal section.
The ventricles are all interconnected.
  • The lateral ventricles are cavities within the cerebrum. The right and left lateral ventricles are separated on midline by the septum pellucidum.
  • The corpus callosum is a large fiber tract of axons connecting the right cerebral hemisphere to the left cerebral hemisphere.
  • The fourth ventricle is located anterior to the cerebellum. It is continuous with the third ventricle through the cerebral aqueduct at its superior border and continuous with the central canal at its inferior border.
  • Narrow passageways connect the ventricles together, so that cerebrospinal fluid flows freely inside the ventricular system.
How many major regions are contained within the diencephalon?
  • The brain stem consists of the midbrain, pons, and medulla oblongata.
  • 3
  • False
  • Thalamus
T/F The inferior colliculi are part of the corpora quadrigemina.
  • The corpus callosum is a large fiber tract of axons connecting the right cerebral hemisphere to the left cerebral hemisphere.
  • The thalamus is the central region of the diencephalon and forms the central core of the brain. The thalamus is enclosed by the cerebrum
  • The medulla oblongata is the lowest region of the brain stem. It is continuous with the spinal cord at the foramen magnum of the skull.
  • True The corpora quadrigemina is a collection of 4 bumps on the posterior surface of the midbrain. It is composed of the 2 superior colliculi and the 2 inferior colliculi.
Which region contains the corpora quadrigemina?
  • The corpora quadrigemina are found on the posterior surface of the midbrain. They can be observed by looking into the transverse fissure.

  • The cerebrum is involved in higher order functions such as consciousness, personality, and intellect.
  • The epithalamus is a region posterior to the thalamus that contains the pineal body.
Which part of the diencephalon is connected to the pituitary gland?
  • Thalamus

  • The epithalamus is a region posterior to the thalamus that contains the pineal body.
  • The thalamus is the central region of the diencephalon and forms the central core of the brain. The thalamus is enclosed by the cerebrum
Cerebrospinal fluid is produced within the ventricles.
  • The cerebrum is involved in higher order functions such as consciousness, personality, and intellect.
  • The cerebral cortex is composed of gray matter. Gray matter is primarily neuron cell bodies.
  • The choroid plexus produces cerebrospinal fluid. It is found in each of the ventricles.
  • The epithalamus is a region posterior to the thalamus that contains the pineal body.
Where is the arbor vitae located?
  • The fourth ventricle is located anterior to the cerebellum. It is continuous with the third ventricle through the cerebral aqueduct at its superior border and continuous with the central canal at its inferior border.
  • The thalamus is the central region of the diencephalon and forms the central core of the brain. The thalamus is enclosed by the cerebrum
  • The white matter in the cerebellum has a branching arrangement that resembles a tree. This structure is named for its appearance. The term arbor vitae means "tree of life."
  • The lateral ventricles are cavities within the cerebrum. The right and left lateral ventricles are separated on midline by the septum pellucidum.
Which ventricles are divided by the septum pellucidum?
  • The fourth ventricle is located anterior to the cerebellum. It is continuous with the third ventricle through the cerebral aqueduct at its superior border and continuous with the central canal at its inferior border.
  • The cerebral aqueduct is the narrow passageway that connects the third and fourth ventricles. It can sometimes be observed on a midsagittal section.
  • The lateral ventricles lie side by side under the corpus callosum, separated by the septum pellucidum.
  • The lateral ventricles are cavities within the cerebrum. The right and left lateral ventricles are separated on midline by the septum pellucidum.
Which area of the brain stem is in contact with the spinal cord?
  • The thalamus is the central region of the diencephalon and forms the central core of the brain. The thalamus is enclosed by the cerebrum
  • The corpora quadrigemina are found on the posterior surface of the midbrain. They can be observed by looking into the transverse fissure.
  • The cerebral aqueduct is the narrow passageway that connects the third and fourth ventricles. It can sometimes be observed on a midsagittal section.
  • The medulla oblongata is the lowest region of the brain stem. It is continuous with the spinal cord at the foramen magnum of the skull.
Which of the following ventricles is found under the corpus callosum?

  • The lateral ventricles lie side by side under the corpus callosum, separated by the septum pellucidum.
  • The central canal is the canal found in the spinal cord that originates off of the fourth ventricle
  • The lateral ventricles are cavities within the cerebrum. The right and left lateral ventricles are separated on midline by the septum pellucidum.
What part of the corpora quadrigemina is clearly observed in a midsagittal section?
