Neurotransmitter
Responsible for muscle activation in the PNS
ACH (acetylcholine)
Embryonic period
The Pons and Cerebellum differentiate from what structure?
Metencephalon
"Stretch sensor" within the intrafusal muscle fiber
Muscle spindle
True or False: Neurotransmitter leaves the presynaptic neuron and enters the postsynaptic neuron
False
Monoamine implicated in Parkinson's disease, ADHD, and Huntington's disease
Dopamine
First three divisions of the encephalon
Prosencephalon, Mesencephalon, Rhombencephalon
The stapes, CN VII, and part of the hyoid bone develop from what pharyngeal arch?
2nd (Hyoid) Arch
Afferent
At resting membrane potential, is the internal charge of the neuron more positive or negative?
Negative
Mood regulating monoamine
Serotonin
Which two divisions make up the "hindbrain"
Metencephalon and Myelencephalon
CN V and the incus & malleus differentiate from this pharyngeal arch
1st (mandibular) arch
Name 4 "special" senses
Vision, Smell, Taste, Hearing
At resting membrane potential, is the neuron polarized or depolarized?
Polarized
Is oxytocin an amino acid, monoamine, or neuropeptide?
Neuropeptide
Name two divisions that differentiate from the Prosencephalon
Telencephalon and Diencephalon
The thalamus, hypothalamus and pituitary gland develop from this structure
Diencephalon
Subconscious knowledge of position and movement of musculoskeletal system
Proprioception
The period during which the neuron CANNOT "fire" again
Absolute Refractory Period
Name the most common excitatory neurotransmitter in the CNS and the most common inhibitory neurotransmitter in the CNS
Glutamate and GABA
These cells are peripheral to the neural tube and eventually become cranial nerves and facial structures
Neural Crest Cells
The midbrain develops from this structure
Mesencephalon
Name three categories of exteroceptors
Mechanoreceptor, Thermoreceptor, Chemoreceptor
What type of "gate" is first "opened" by the neurotransmitter substance?
Ligand gate
