Synaptic Transmission
The type of synapse that involves releasing a chemical agent from the presynaptic neuron to the post-synaptic neuron.
What is chemical synapses?
The brain and spinal cord make up this part of the nervous system (acronym).
What is the CNS?
Summation of twitch forces in response to multiple action potentials.
What is tetanus?
Defined as an exercise-induced reduction in the ability of muscle to produce force or power, whether or not the task can be sustained.
What is fatigue?
This neuron conveys sensory information to CNS from stimuli in the periphery (e.g. nociceptors or free nerve endings indicating noxious stimuli).
What is the afferent neuron?
The place in the neuron where action potentials are generated
What is the axon hillock?
EPSP and IPSP, synaptic activity, and intrinsic excitability are this type of change in response to injury
What are functional changes?
The force involved in a single action potential.
What is twitch?
Fatigue taxonomy is divided into two branches: perceived fatigability and ___________________.
What is performance fatigability?
Provides rapid feedback about changes in muscle length.
What is the muscle spindle?
__________ summation involves multiple synapses or locations.
What is spatial?
Autoimmune disorder that disrupts myelination of peripheral nerves, with primary symptoms of muscle weakness and tingling (paralysis).
What is Guillain-Barre Syndrome?
The control of voluntary actions by the nervous system is accomplished by modulating the activity of _________ motor neurons.
What is few?
Homeostasis is part of this sub-branch of fatigue.
What is perceived fatigability?
Provide feedback about muscle force.
What is the Golgi tendon organ?
The structure in the neuromuscular junction that is disabled by BoTox.
What is fusion proteins?
This is a strategy to improve motor function that involves recovery, and refers to activating brain areas in which function has been compromised.
What is restoration?
This method extracts the force contributed by a single motor unit to the net muscle force during sustained voluntary contractions. Action potentials produced by the motor unit trigger an averaging device that samples the muscle force at that time point, and this calculates a running average from many triggered events.
What is spike-triggered averaging (STA)?
Neuromuscular propagation is tested with this, which is the response of alpha motorneurons caused by APs evoked by the electrical stimulation of axonal fibers.
What is the M-wave?
Golgi tendon organs work through a negative feedback system. Increased activity leads to excitation of this interneuron
What is Ib inhibitory?
anterograde axonal transport is driven by this enzyme
what is kinesin?
The type of motor recovery where residual neural tissue takes over a function that has been lost due to injury or disease.
What is compensation?
The properties of human motor units are best characterized by measuring _______________ and twitch force.
What is recruitment threshold?
Humans encounter these four types of loads.
What are elastic, immovable, inertial, and viscous?
The reflex can be evoked by an application of electrical stimulus to a peripheral nerve and record the twitch or muscle activity of the muscle that it innervates.
What is the Hoffman reflex?
