Study Notes
Motor Neuron and Muscle Fiber Interactions
- The neuromuscular junction is the structure responsible for initiating the contraction of skeletal muscle.
- Regulated exocytosis, a step in neurotransmitter release, is inhibited by Botox.
- Axon terminals of motor neurons form synapses with muscle fibers at the neuromuscular junction, enabling transmission of signals from neuron to muscle.
