The basic functional and anatomical organization of nerves and muscle fibers within skeletal muscle.
A motor neuron and the muscle fibers activated by it.
refers to the relationship of a single motorneuron axon to the number of muscle fibres it innervates
All of the muscle cells controlled by a single motor neuron.
a group of muscle fibers all supplied by one motor nerve
a motor nerve and all the muscle fibers that it innervates
a motor neuron attached to muscle fibers
a motor neuron with the muscle fibres it innervates
an alpha motoneuron (originating in the spinal cord) and all of the muscle fibers that it innervates
a nerve and all the muscle fibers innervated by the nerve
a nerve cell (or neuron) and the muscle fibers it activates
a single Motor Neuron and all of the Muscle Fibers it is responsible for
The bundle of muscle fibres innervated by a single motor end-plate. Can be of widely differing size: in eye muscles there are seven muscle fibres per nerve fibre, but in leg muscles this rises to 1700 muscle fibres per nerve fibre.
The functional unit of muscular contraction consisting of a motor nerve and the muscle fibers it innervates.
A motor nerve and all the muscle fibers it stimulates; In the quadriceps muscle, one neuron can activate as many as 1,000 fibers. In the eye, where great precision is required, one nerve cell may control only 3 fibers.
The unit of motor activity consisting of a motor neuron and the muscle fibers it innervates; important in producing graded muscle force.
A single motor neuron and all of the muscle cells that receive synaptic connections from that motor neuron.
Anterior horn cells in spinal cord, their axons and the skeletal muscle fibres innervated by them. Depending on role, a few or many muscle fibres may be within the motor unit.
A motoneuron and all the muscle fibers it stimulates, innervates, or activates. The size of the motor unit is usually related to the degree of control required by the whole muscle.
A motor unit is a single α-motor neuron and all of the corresponding muscle fibers it innervates. Groups of motor units often work together to coordinate the contractions of a single muscle; all of the motor units that subserve a single muscle are considered a motor unit pool. The number of muscle fibers within each unit can vary: thigh muscles can have a thousand fibers in each unit, eye muscles might have ten.
