Flashcards in Module #5 - Muscle Histology And Physiology Deck (11)
The repeating unit of a myofibril.
The functional unit of the nervous system, a nerve cell.
The interface between a nerve cell and another cell.
A chemical released by a neuron. This chemical travels across the synaptic cleft, allowing the neuron to communicate with another cell.
One motor neuron and all the muscle fibers it innervates.
All-or-none law of skeletal muscle contraction
An individual muscle fiber contracts with equal force in response to each action potential.
A stimulus too small to create an action potential in a neuron.
A stimulus strong enough to create one action potential in a neuron.
Stimuli of increasing strength that create more action potentials along more neurons.
A stimulus which is strong enough to create action potentials in all the motor neurons innervating a whole muscle.
