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 nutrient is not digested but stimulates intestinal muscle contractions?
The nutrient that is not digested but stimulates intestinal muscle contractions is fiber. Fiber is a type of carbohydrate that may be soluble or insoluble.
What stimulates intestinal muscle contractions?
Nicotien or anything chemical which stimulates the Nicotinic receptors.
What stimulates contractions in uterine smooth muscle during labor?
Oxytocin
What Neurotransmitter that activates skeletal muscle fibers?
Acetal Choline (ACh)
What are the three types of contractions of skeletal muscle?
isotonic concentric eccentric isometric
Muscle contracts to move?
the muscles and the bone work together and attached
Can skeletal muscle be tetanised?
Yes, because of the short refractory period of skeletal muscle (compared to cardiac muscle), skeletal muscle can be restimulated before the muscle is completely relaxed. If repeated enough times, the contractions fuse together i.e. they become tetanised.
What muscle skeletal muscles do to move?
Skeletal muscles rely on contractions to move the bone they are attached to so it is contract and relax
What refers to one neuron and all skeletal muscle cells it stimulates?
Motor unit
What refers to one neurone and all the skeletal muscle cells it stimulates?
The motor unit.
What is the role of acetylcholine in skeletal muscle contractions?
acetylcholine as far as i know is a neurotransmitter that ativates the mscle cells.
