What type of excitatory neurotransmitter is secreted by motor neurons innervating skeletal muscle?

Acetylcholine is the excitatory neurotransmitter released by neurons innervating skeletal muscles. Acetylcholine release stimulates muscle contraction by acting at the nicotinic-acetylcholine receptor on the surface of the muscle cell.

What is an excitatory neurotransmitter secreted by motor neurons innervating skeletal muscles?
acetylcholine
What neurotransmitter stimulates skeletal muscle contractions?
Acetylcholine
What Neurotransmitter that activates skeletal muscle fibers?
Acetal Choline (ACh)
Why do skeletal muscle cells have high numbers of micro filaments?
because many proteins are secreted as hormones
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.
Is acetylcholine an catecholamines?
Its a stimulatory and Inhibitory in nature..eg..it induces contraction of skeletal muscles fibres & inhibits contraction in cardiac muscle fibres. ---------------------------------------------------------Recommend if u like this.....
What is the difference between an excitatory synapse and an inhibitory synapse?
Synapses are junctions that allow a neuron to electrically or chemically transmit a signal to another cell. Synapses can either be excitatory or inhibitory. Inhibitory synapses decrease the likelihood of the firing action potential of a cell while excitatory synapses increase its likelihood. Excitatory synapses cause a positive action potential in neurons and cells. For example, in the neurotransmitter Acetylcholine (Ach), its binding to receptors opens up sodium channels and allows an influx of Na+ ions and reduces membrane potential which is referred to as Excitatory Postsynaptic potential(EPSP). An action potential is generated when the polarization of the postsynaptic membrane reaches threshold. ACh acts on nicotinic receptors which can be found at the neuromuscular junction of skeletal muscles, the parasympathetic nervous system, and the brain. It also acts on muscarinic receptors found at neuromuscular junctions of the smooth muscles, glands, and the sympathetic nervous system. Inhibitory synapses, on the other hand, cause the neurotransmitters in the postsynaptic membrane to depolarize. An example is the neurotransmitter Gamma Aminobutyric Acid (GABA). The binding of GABA to receptors increases the flow of chloride (CI-) ions in the postsynaptic cells raising its membrane potential and inhibiting it. The binding of GABA to receptors activates a second messenger opening potassium channels.
What is the name of the neurotransmitter released by sympathetic nerves and also act on the heart blood vessels large skeletal muscles and accelerates metabolism?
acetylcholine
Movement of arms and legs what major neurotransmitter involved?
Skeletal muscles move via action potential that is conducted by axons to the neuromuscular junction and across the synaptic gaps of efferent motor neurons. The main neurotransmitter responsible for this job is acetylcholine.
What is the neurotransmitter that initiates muscle contraction?
Voluntary muscle contraction is controlled by the central nervous system. The brain sends signals, in the form of action potentials, through the nervous system to the motor neuron that innervates several muscle fibers.Acetylcholine (ACh) is commonly secreted at neuromuscular junctions, the gaps between motor neurons and muscle cells, where it stimulates muscles to contract (by opening gated positive ion channels).
What neurotransmitter control the somatic nervous system and how does it work?
Acetylcholine (ACh) is the only neurotransmitter used in the motor division of the somatic nervous system. It works by binding to acetylcholine receptors on skeletal muscle fibers and opening ligand-gated sodium channels in the cell membrane.
