The stimulus that travels from the motor neuron to skeletal muscle is an electrical signal known as an action potential. When the action potential reaches the neuromuscular junction, it triggers the release of neurotransmitters, specifically acetylcholine, from the motor neuron. This neurotransmitter binds to receptors on the muscle cell membrane, leading to muscle contraction. The entire process is essential for voluntary movement and muscle coordination.
What else can I help you with?
What kind of stimulus travels from the motor neuron to skeletal muscle?
The stimulus that travels from the motor neuron to skeletal muscle is an electrical signal called an action potential. This action potential causes the release of neurotransmitters, specifically acetylcholine, which then stimulates muscle contraction.
What kind of stimulus (electrical or chemical) travels from the motor neuron to skeletal muscle?
This is done through a neurotransmitter. So the answer is chemical.
Which of these cells are likely to have multiple nuclei skeletal muscle cardiac muscle smooth muscle or neuron?
skeletal smooth muscle neuron
Which type of muscle requires a motor neuron?
Skeletal muscle.
The all-or-none law applies to skeletal muscle function at what level?
The all-or-none law applies to individual muscle fibers within a skeletal muscle. This means that when a muscle fiber is stimulated by a motor neuron, it will either contract maximally or not at all, depending on whether the stimulus reaches the threshold for activation.
What is the somatic reflex arc?
The somatic nervous system is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles. The SoNS consists of efferent nerves responsible for stimulating muscle contraction, including all the non-sensory neurons connected with skeletal muscles and skin.
What is the message that travels through the neuron?
An Impulse
How are the Neuron and skeletal muscle fiber connected?
they are connected with the rope in the body
How is a skeletal muscle fiber stimulated by a motor neuron?
motor unitUnit
Skeletal muscle fiber is controlled by a motor neuron at a single?
Each muscle cell is only innervated by a single motor neuron, but each motor neuron innervates any number of muscle cells. When an action potential travels down the axon of an alpha motor neuron, it will depolarize several muscle cells at the same time, a phenomenon known as summation.
What happens at the level of the neuron starting with stimulus and ending with a response?
The stimulus is detected by the sensory receptor. The sensory receptor stimulates a sensory neuron. The sensory neuron transmits to the interneuron in the spinal cord. The interneuron stimulates a motor neuron. The motor neuron communicates to the muscle. The muscle(effector) then produces the response allowing the body to respond to the stimulus.
Each skeletal muscle fiber is controlled by a motor neuron at a single?
neuromuscular junction
