Name 4 types of glia and their function
What is
astrocytes = BBB, maintain environment
microglia = immune cells of brain
oligodendrocytes = makes up myelin sheath of CNS
Schwann cells = makes up myelin sheath of PNS
100
Thalamus and hypothalamus is derived from which region of neural tube
What is diencephalon
100
Parts of an atom with charges
What is
Middle/nucleus = proton (+) and neutron (no charge)
Outside/shells = electrons (-)
100
Concentration of ions at rest
What is more sodium outside what is more potassium inside
100
Major excitatory and major inhibitory NT
what is glutamate and GABA
200
Draw a diagram of a neuron and label the parts
What is diagarm of a neuron
200
Germ layer that majority of nervous system develops from
What is ectoderm
200
Products of mitosis and meiosis
Mitosis = two identical daughter cells
Meiosis = 4 non-identical gametes
200
membrane potential change under threshold
what is graded potential
200
name of acetylcholine ionotrophic and metabotrophic channels
I = nicotinic
M = muscarinic
300
Innervation of the somatic nervous system
What is skeletal muscle
300
Order of ventricles
lateral- intraventricular foramen - 3rd - cerebral aqueduct - 4th
300
Oxygen's role in cellular respiration
Final electron acceptor
300
Channel roles, when do they open, ions that flow through
What is
-Voltage gated sodium = opens threshold potential
Na comes into cell through passive transport
- Voltage gated potassium = opens threshold potential
K leaves cell through passive transport
- Na-K pump = always open
3 na out 2 K in
300
precursor of catecholamine synthesis
Tyrosine
400
Draw/describe 3 differences between sympathetic and parasympathetic nervous system
What is function
P = Rest and digest
S = Fight or flight
What is neurotransmitters
P = acetycholine
S = acetylcholine AND norepinephrine + epinephrine
What is origin in spine
P = thoracic and lumbar
S = cervical and sacral (organized in sympathetic chain ganglia)
400
PPT slide 1 (answer 1-5)
Double points (explain function as well)
See slide
400
Location, and function of each metabolic pathway
Glycolysis = anaerobic, cytoplasm/cytosol to create small amounts of ATP and a product of citric acid cycle (pyruvate)
Citric acid cycle = mitochondrial matrix, to create high energy electron carriers for ETC
Electron transport chain = aerobic, mitochondrial membrane, to create huge amounts of ATP using oxygen as the final electron acceptor
400
Draw action potential chart
Slide ppt 6
400
Agonists, antagonists of acetylcholine channels including effect
Slide
500
Draw the diagram of innerviation of sympathetic and parasympathetic innerviation (including sympathetic exception)
(slide 20 chapter 1)
500
Explain pairs of anatomical directions
slide ppt 4
500
Your SI's roommates names
Jessica and Dan
500
Draw the refractory periods on AP chart
Explain why we have them
Slide
-What is preventing the signal from traveling backwards
-Relative: undershoot of hyperpolarization due to increased stimulus to reach threshold
-Absolute: inactivation of sodium channels prevents a new AP from forming
500
Steps of synaptic transmission
What is
1. Action potential arrives
2. voltage gated Ca opens and Ca influx
3. Ca causes synaptic vesicles to move to membrane
4. exocytosis of neurotransmitters
