Can you be more specific to the question
Answer:
excitable
Explanation:
All muscle types will respond to an electrical stimulus because all muscle cells are excitable.
Excitability is response of muscle to signal which delivered through the motor neuron.
Excitability is stretching of muscles.
The contraction and relaxation of muscle occur in following way:
Muscle contraction begins with signal. The contraction occur when nervous system send signals. The impulse which is called signal is travel through a motor neuron.
The whole process include following three steps:
1) Message is traveled from nervous to muscular system and trigger the chemical reaction.
2) This chemical reaction causes the muscle fibers to reorganize in such a way that shorter the length of them which is called contraction.
3) when this signal is no longer remain , reverse chemical process occur and muscles relax.
So yellow is mostly the classification of <em>Metal, </em>But I don't see that option here. Answer-Blue
