Nerves of Steel
This substance helps speed the propagation of action potentials down the nerve
Myelin
In response to blocked receptors, receptors will increase due to this response by the body
Upregulation
These act as the site of depolarization across the nerve fiber
Nodes of Ranvier
These are the descending motor tracks
Corticospinal tracts
Cranial nerves are considered a part of this branch of the nervous system
Peripheral nervous system
These slow fibers primarily serve the modality of pain and temperature
C Fibers
These intracellular proteins activate numerous responses including activation of enzymes, vasoactivation, muscle contraction, and secretion of hormones
G Proteins
This is the primary excitatory neurotransmitter in the CNS
Glutamate
The location for connectivity with other nervous components in the form of synapses
Most synapses within the brain fall under this broad category of mediation
Rank A,B,C fibers from largest to smallest and fastest to slowest
Size : A > B > C
Speed: A > B > C
Specific to fetuses, cholinergic receptors are found in this area rather than specifically at the NMJ
Throughout the muscle
The ability of a nerve to depolarize is dependent on the stage of this quality
Membrane potential
This space consisting of Rexed Laminae II and III is where the paleospinothalamic tract begins and slow C fibers enter
Substantia gelantinosa
This portion of the brain is responsible for actions that do not require conscious effort such as breathing and circulatory control
Brainstem
This specific type of A fiber propagates proprioception
Alpha
This channel is particularly important to anesthesia for its ability to act as a conduit for chloride, hyperpolarizing the cell
Sustained depolarization due to certain anesthetics may result in this unusual hypermetabolic state
Malignant hyperthermia
Sensory input, regardless of fast or slow, enter the spinal cord through this portion of the gray matter
Dorsal horn
These divisions are denoted to associate specific area of the brain to control of specific anatomical regions
Brodmann Areas
The 31 spinal nerves are broken down into these categories (and the specific number of each)
8 Cervical
12 Thoracic
5 Lumbar
5 Sacral
1 Coccygeal
pH plays favorites for excitation and inhibitoin. Acidosis states results in this prominence
Inhibitory
The ability to depolarize without propagation or stimulus
Automaticity
The ascending dorsal column transmits these three categories of information
Vibration
Pressure with fine distinction
This area of the brain allows the ability to learn new memories and long term storage
Hippocampus
