An incoming action potential to an alpha motor neuron causes acetylcholine (Ach)release at the end plate, Ach binds to Ach receptors on the sarcolemma causing a sodium influx which causes depolarization.

What is the fiber yielding animals?
the animal which gives fibre is fibre yielding animals Example.etc....
Is angora fibre a vegetable fibre?
Angora is a staple fiber because it is a natural fiber. All natural fibers, with the exception of silk, are in the staple form. Since angora comes from angora rabbits or angora goats, the fibers are sheared or pulled, and are not continuous.

In a muscle fibre, the key intracellular event that stimulates muscle contraction is known as ?

How is Co2 removed from muscle fibre?

What nutrient causes gelatinisation?
soluble fibre?
What is the function of cytoplasmic reticulum in the muscle fiber?
increases calcium influx in the muscle fibre, causing contraction.
Fast twitch fibers are also called?
Type 2 muscle fibre.
Physiological muscle fatigue is caused by?
1. An increasingly acidic environment (acidosis) causes a breakdown in the chemical reactions that produce muscle fibre contractions (acidosis is caused by the build-up of lactic acid and the release of hydrogen ions.) This is most likely to occur during high to intense levels of exercise. 2. Glucose reserves are depleted during sustained periods of work. 3. There is a change in the balance of the chemicals that propagate the nervous stimulus (the action potential) within the muscle fibre. This decreases the excitability of the muscle fibre and therefore reduces its ability to contract; it fatigues.
What has the author Lillie written?
Lillie has written: 'The physiological significance of the segmented structure of the striated muscle fibre' -- subject(s): Striated muscle
How many sarcomere in a muscle cell?
There are unknown amounts of fibers (fibre) in muscles
Is cardiac muscle multinucleate or uninucleate?
It is uninucleate not because it has one cell, but because each cell in that muscle has 1 nucleus.
Do the quadriceps or the biceps have more motor units?
Every muscle (no matter which muscle, even a single muscle fibre-unit) have several motor neurons.
