Major center for afferent (SENSORY) impulses to the cerebral cortex - CORRECT ANSWER-
Thalamus. Relay center for information from the basal ganglia and cerebellum to appropriate
motor area
What is cortical processing - CORRECT ANSWER-Interpretation of sensations
What are the main functions of the Hypothalamus? - CORRECT ANSWER--Maintains
Homeostasis
-Implements behavioral patterns
-Visceral and somatic responses
-Affectual Responses
-Hormone synthesis
- Body temp regulation
- Regulation of physical expression of emotions
-Sexual behavior
,-Pleasure-punishment center
- Level of arousal or wakefulness
Where is the Tecum (corpora quadrigemina) located? what does it do? - CORRECT ANSWER-
Roof of the midbrain
Subthalamus. Location? Important function? - CORRECT ANSWER-Lateral to thalamus.
Important ganglia center for motor activities
What are the paired structures within the Tectum? - CORRECT ANSWER-Superior Colliculi -
visual motor movements
Inferior Colliculi - auditory motor movements
Where is the location of the Superior Colliculi? Function? - CORRECT ANSWER-Tectum of the
Midbrain. controls voluntary and involuntary visual motor movements such as the ability of the
eyes to track moving objects in the visual field.
Where is the location of the Inferior Colliculi? Function? - CORRECT ANSWER-Tectum of the
midbrain. controls motor activities affecting the auditory system such as positioning the head to
improve hearing. MAJOR relay center along the auditory pathway
Location of Tegmentum? Function? - CORRECT ANSWER-Floor of midbrain. Includes Red
nucleus and Substantia nigra. Provides communication between motor and sensory areas.
Storage, analysis, and interpretation of stimuli
Location of Red nucleus? function? - CORRECT ANSWER-In Tegmentum in the Midbrain.
receives ascending sensory information from the cerebellum and projects a minor motor
pathway (rubrospinal tract) to the cervical spinal cord
, Location of Substantia niugra? Function? - CORRECT ANSWER-In the Tegmentum of the
midbrain. Synthesizes dopamine. Dysfunction of dopaminergic neurons in the substantia nigra is
associated with Parkinson's disease and schizophrenia
Location of Cerebral Peduncles? Function? - CORRECT ANSWER-Anterior midbrain. Contains
nuclei of the 3rd and 4th (III&IV) cranial nerves.
Cerebral aqueduct (aqueduct of Sylvius) + carries CSF between 3rd and 4th ventricles.
Obstruction of the cerebral aqueduct (aqueduct of Sylvius) in the anterior midbrain is a
common cause of what? - CORRECT ANSWER-Hydrocephalus. Cerebral aqueduct carries fluid
between the 3rd and 4th ventricle
Location of Cerebellum? Function? - CORRECT ANSWER-Hindbrain. Composed of two lobes of
grey and white matter. Divided by central fissure. Connected by the Vermis. *Responsible for
reflexive, involuntary fine-tuning of motor control ( conscious and unconscious muscle energy)
*Maintaining balance and posture (via connections with the medulla and the midbrain)
* Control of the body = ipsilateral (same side);: damage to the cerebellum is characterized by
loss of equilibrium
What connects the two lobes of the Cerebellum? - CORRECT ANSWER-The Vermis
Location of the Pons and its function? - CORRECT ANSWER-Hindbrain. "bridge" below the
midbrain and above the medulla. Transmits information from the cerebellum to the brainstem
(between the two hemispheres)
*Contains nuclei of the 5th-8th (V-VIII) cranial nerves
*Aids in controlling respirations
Location and function of the Medulla Oblongata - CORRECT ANSWER-Lowest portion of the
brainstem (hindbrain).
