Neurons
Name the inhibitory neurotransmitters
GABA and Acetylcholine
Responsible for phagocytosis of microbes and damaged nervous tissue
Microglia Cells
Name the layers of meninges from superficial to deep
dura mater, subdural space, arachnoid mater, subarachnoid space, pia mater
Where is CSF made?
In the ventricles by the choroid plexuses
List the direction of a nerve impulse starting with a dendrite
Dendrite -> cell body -> axon -> axon terminal -> synaptic end bulb
Lines ventricles in the brain and central canal, produces and monitors the flow of CSF, and forms the blood-cerebrospinal fluid barrier
Ependymal Cells
Name the layers of connective tissue of a nerve from superficial to deep
Epineurium, perineurium, endoneurium
The epithalamus, thalamus, and hypothalamus are part of which secondary brain vesicle
Diencephalon
Name the two components of the Autonomic Nervous Systems and how they affect heart rate and the gastric and intestinal motility
Sympathetic Nervous System: increases HR and decreases GI
Parasympathetic Nervous System: decreases HR and increases GI
Provide insulation to neuros in the CNS
This nerve is responsible for the sensory input in the spinal cord
Dorsal root ganglion
This brain region contains motor and sensory fibers and the corpora quadrugemina: two superior colliculi and two inferior colliculi
What type of neurons are pseudounipolar/unipolar?
Sensory neurons
Creates the blood brain barrier, maintain an ideal environment for action potentials, and plays a role in learning and memory
Astrocytes
What tissue subtype is the dura mater made up of?
Dense irregular connective tissue
This brain region is responsible for the cardiovascular center, respiratory center, and center that controls reflexes for vomiting, coughing, and sneezing.
Medulla oblongata
What transport mechanism allows neurotransmitters to reach their specific receptors?
Simple diffusion
Regulates exchange of materials between the cell body and interstitial fluid, only in PNS
Satellite Cells
Which meninge protects the spinal cord against displacement that could result in shock?
Pia mater
What are the functions of the hypothalamus
Major regulators of homeostasis, regulation of eating and drinking, regulation of body temperature, and production of hormones
