L1/L2
100
The Nervous System initially divides into the
CNS - Central Nervous System
PNS - Peripheral Nervous System
100
Produces CSF
Ependymal Cells
200
(In Roman Numerals) This cranial nerve is split into 3 branches
BONUS 100: Name the foramen each branch goes through

300
(In Roman Numerals) This cranial nerve is responsible for lateral ABduction of the eye
CN VI - Abducens
300
One of it's primary functions is satiety
BONUS 100: List 4 types of satiety
Hypothalamus
300
Balance and Coordination
Cerebellum
300
The PNS further divides into...
ANS - Autonomic Nervous System
SNS - Somatic Nervous System
300
This cell helps maintain the blood-brain barrier (BBB)
Astrocytes
400
What is the name of CN IX and what are it's functions
Cranial Nerve 9 - Glossopharyngeal Nerve
Modality: Both sensory and motor
Sensory: Taste in the back 1/3 of the tongue
Motor: Swallowing
400
********Shaped like a pinecone, produces melatonin
Pineal Body/Gland
400
3 Locations of CSF in the CNS
Central Canal of the spinal cord
Ventricles of the brain
Subarachnoid space (brain and spinal cord)
400
The ANS further divides into
Sympathetic Nervous System (Fight or Flight)
Parasympathetic Nervous System (Rest & Digest)
400
This cell myelinates axons in the CNS
Oligodendrocytes
500
(In Roman Numerals) These 2 cranial nerves are the main 2 responsible for taste
CN VII - Facial Nerve (front 2/3)
CN IX - Glossopharyngeal Nerve (back 1/3)
500
This cortex could be found in the Precentral Gyrus
Motor Cortex
500
Regulates BP, HR, RR, and swallowing
Medulla Oblongata
500
Activation of this division of the ANS would increase digestive functions
Parasympathetic NS (Rest and Digest)
500
Phagocytosis
Microglia
600
(In Roman Numerals) The parasympathetic nervous system is associated with these 4 cranial nerves
CN III - Oculomotor Nerve
CN VII - Facial Nerve
CN IX - Glossopharyngeal Nerve
CN X - Vagus Nerve
600
Someone with Broca's aphasia would have difficulty with what (speaking/thinking)
Speaking
600
*********If you poke through the 3rd ventricle, you'll find yourself in what
Thalamus/Hypothalamus/Thalamic Nuclei
600
Activation of this division of the ANS would result in pupil dilation
Sympathetic (Fight or Flight)
- Need to see more of surroundings, maximum visual information
600
Really Tired Drink Coffee Now stands for what
Divisions of the Brachial Plexus
R - Roots
T - Trunks
D - Divisions
C - Cords
N - Peripheral Nerves
700
(In Roman Numerals) The 3 cranial nerves that go through the Jugular Foramen
CN IX - Glossopharyngeal
CN X - Vagus
CN XI - Accessory Spinal
700
The "emotional cortex" of the brain
Cingulate Gyrus
700
**********The place where the dorsal and ventral roots join to form the spinal nerves
IVF - Intervertebral Foramen
700
Activation of this division of the ANS would result in artery constriction
Sympathetic (Fight or Flight)
- Less blood flow to limbs, keeps blood in core
700
Denticulate Ligaments of the spinal cord are what type of mater
Pia Mater
800
Each cranial nerve modality from I-XII
(S/M/B)
I - S
II - S
III - M
IV - M
V - B
VI - M
VII - B
VIII - S
IX - B
X - B
XI - M
XII - M
800
Circadian Rhythms, Internal Clock, Located in Hypothalamus
SCN - Suprachiasmatic Nucleus
800
Only in the spinal cord, this is the name of the space directly superficial to the dura mater
Epidural Space
Epi (superficial) + Dura (dura mater)
= superficial to the dura mater
800
The apneustic center is located in the
Pons
800
This mater is continuous with the epineurium
Dura Mater
