What are the four parts of the Human Brain (part of the Central Nervous System)?
1. Cerebrum
2. Diencephalon
3. Brain Stem
4. Cerebellum
How are Sulci and Gyri formed? (And which are elevations/depressions?)
Sulci - Depressions
Gyri - Rounded Elevations within each lobe

Sulci and Gyri are formed when the brain gets larger & folds upon itself
What are the four functions of the Cerebrum?
The cerebrum is involved in:
1) Voluntary Motor Function
2) Sensory Perception
3) Special Sensory Functions
4) Language and Learning
What is and where is Gray and White Matter?
Gray Matter is the EXTERNAL COVERING of the cerebrum it is made up of *Neuronal cell bodies and Glial cells*

White Matter is INTERNAL to the cerebrum or deep to the cortex. It is involved in *cell processes and is made up of Glial cells*
What is the Paracentral Lobule?
The Paracentral Lobule is viewed from the medial aspect made up of the PRECENTRAL & POSTCENTRAL GYRI
The Cerebral cortex is made up of Fissures & Sulci, and Gyri. How does the Longitudinal Fissure divide the brain?
Divides into two hemispheres
What and where is the Limbic lobe?
The Limbic Lobe contains the Olfactory System and Emotion. It is functional, but not anatomical.
What makes up the Diencephalon (Central core of the cerebrum)?
- THALAMUS
- SUBTHALAMUS
- EPITHALAMUS
- HYPOTHALAMUS
What is the Pineal Body attached to?
- The Pineal Body is an oval glad at the end of the Epithalamus
What part of the Diencephalon controls most of the body's hormones?
The Infundibulum
What is the Infundibulum attached to?
- The Hypothalamus
What is at the end of the Infundibulum Stalk?
- The Pituitary Gland
What are the Parts of the Brain Stem?
- Midbrain
- Superior Colliculi
- Inferior Colliculi
- Pons
- Medulla Oblongata
True or False: The Superior Colliculi is involved with the Visual System.
True
The Inferior Colliculi is involved with controlling what system?
The Auditory System
What is the Cerebellum responsible for?
- Equilibrium
- Muscle tone
What is the primary function of the Meninges?
The Meninges are connective tissue that hold and cushion the brain to PROTECT the CENTRAL NERVOUS SYSTEM.
The Central Nervous System is comprised of the __________ and the _________.
The Central Nervous System is comprised of the BRAIN and the SPINAL CORD.
The Central Nervous System receives information. What kind of information does the Central Nervous System receives?
The Central Nervous System receives input or AFFERENT INFORMATION about our external and internal environment.
The Epidural Space is just outside of the (what type of Mater)?
Dura Mater
Which Layer of the Meninges is delicate, lines the Dura, and is weblike in appearance?
The Arachnoid Space
The sub arachnoid space is between what layers of the meninges?
The Subarachnoid space is under the Arachnoid Mater, and above the Pia Mater.
What space contains Cerebrospinal Fluid?
Subarachnoid Space
Which layer of the meninges is thin and adheres to the brain and spinal cord?
Pia Mater
Which layer of the meninges follows in sulci & gyri?
Pia Mater
What is the purpose of the Ventricles and the Choroid Plexus?
To produce cerebraospinal fluid for the subarachnoid space.
Where is cerebraospinal fluid formed?
In the Choroid Plexus
What the Choroid Plexus made up of?
Cell and Capillaries
The Choroid Plexus is in what ventricle(s)?
a. Lateral Ventricle
b. Third Ventricle
c. Fourth Ventricle
d. B & C
e. All of the Above
E. The choroid plexus is located in ALL ventricles therefore all ventricles produce CSF (Cerebrospinal Fluid)
Where does the Cerebrospinal Fluid flow (chronologically)?

a. Third Ventricle
b. Foramen of Monroe
c. Fourth Ventricle
d. Lateral Ventricle
e. Subarachnoid Space
f. Cerebral Aqueduct
g. Surround Brain
d. Lateral Ventricle
b. Foramen of Monroe
a. Third Ventricle
f. Cerebral Aqueduct
c. Fourth Ventricle
e. Sub Arachnoid Space
g. Surround Brain
Where does Cerebrospinal Fluid go after it has surrounded the brain?
It exits via the ARACHNOID VILLI into the SUPERIOR SAGITTAL SINUS it opens valves to the superior sagittal sinus when the pressure is high enough. Cerebral Spinal Fluid can flow into blood. The valves do not allow blood IN.
True or False:

The 12 cranial nerves are part of the
PERIPHERAL NERVOUS SYSTEM?
True
What is CV (IV)?
Trochlear
What does the Olfactory Nerve control?
Sensory - Sense of smell
What nerves pass through the Superior Orbital Fissure?
Oculomotor, Trochlear, Opthalmic, and the Abducens
What nerves move the eye?
Trochlear, Oculomotor, and the Abducens
Where does CN I pass through?
The Cribiform plate
This Nerve provides motor to the Pharynx and controls salivation, taste and sensory to tongue.
Glossopharyngeal (CN X)
What are the three twins of the Trigeminal Nerve?
Opthalmic, Maxillary, and Mandibular
What does the Spinal Accessory nerve innervate?
Motor to Trapezius and Sternocleidomastoid
What nerve has:
