Yes, each skeletal muscle fiber has one neuromuscular junction (NMJ) where a motor neuron connects to the muscle fiber. This junction is the site where the motor neuron releases neurotransmitters, specifically acetylcholine, to stimulate muscle contraction. While a single motor neuron can innervate multiple muscle fibers, each individual muscle fiber receives input from only one motor neuron at its NMJ.
What else can I help you with?
Each skeletal muscle fiber is controlled by a motor neuron at a single?
neuromuscular junction
Skeletal muscle fiber contraction begins when?
Acetylcholine is released into the neuromuscular junction by the axon terminal
What is the site where the muscle fiber and nerve fiber meet called?
Well of course they meet at the neuromuscular junction
What is the chemical used at the junction with a skeletal muscle?
The chemical used at the junction with a skeletal muscle is acetylcholine (ACh). It is released from the motor neuron at the neuromuscular junction and binds to receptors on the muscle fiber's membrane, triggering muscle contraction. This process is essential for voluntary movement and is part of the overall neuromuscular signaling mechanism.
What is the narrow space that separates the motor neuron and the skeletal muscle fiber in a neuromuscular junction called?
Neuromuscular junction or neuromuscular synapse
The synapse of a motor neuron with a muscle fiber is known as the what?
neuromuscular junction
What are the 3 structural components of a neuromuscular response?
The three structural components of a neuromuscular response are the motor neuron, the neuromuscular junction, and the muscle fiber. The motor neuron transmits signals from the brain or spinal cord to the muscle, the neuromuscular junction is where the motor neuron and muscle fiber meet and communicate, and the muscle fiber is the contractile tissue that generates force in response to nerve signals.
Action potentials are conducted into a skeletal muscle fiber by?
C. neuromuscular junctions
At the neuromuscular junction the muscle fiber membrane is folded to form?
motor end plate
What does the neuromuscular junction consist of?
the axon terminal coming into close proximity to a muscle fiber
What two structures approach each other at a neuromuscular junction?
At a neuromuscular junction, the motor neuron terminal and the muscle fiber membrane (sarcolemma) approach each other. The motor neuron releases the neurotransmitter acetylcholine, which binds to receptors on the muscle fiber membrane, initiating muscle contraction.
What position on the muscle cell where the nerve fibers connect?
The point where a nerve fiber connects to a muscle cell is known as the neuromuscular junction. This connection allows the nerve signal, or action potential, to be transmitted from the nerve to the muscle cell, triggering muscle contraction.
