$\dashrightarrow$Muscular tissue

$\textbf{\large{\red{Question 3}} }$

$\dashrightarrow$Cardiac muscle tissue works to keep your heart pumping through involuntary movements. This is one feature that differentiates it from skeletal muscle tissue, which you can control. It does this through specialized cells called pacemaker cells. These control the contractions of your heart.

$\textbf{\large{\red{Question 4}} } </p><p>$

$\dashrightarrow$Skeletal muscles are long and cylindrical in appearance; when viewed under a microscope, skeletal muscle tissue has a striped or striated appearance. The striations are caused by the regular arrangement of contractile proteins .

$\textbf{\large{\red{Question 5}} } </p><p>$

$\dashrightarrow$Cardiac muscle fibers look a lot like both smooth and striated muscle fiber because it is uninucleated & has dark as well as light bands called as striations. ... Cardiac muscle is kept under involuntary control so it tends to contract rhythmically under autonomous nervous control rather than conscious control.

$\textbf{\large{\red{Question 7}} } </p><p>$

$\dashrightarrow$Fiber length and size can vary considerably within a given muscleand between different muscles. Therefore, numbers of nuclei can range from 50-1000 per fiber. For instance in B6 mice an FDB fiber will contain about 30-50 nuclei, while a Soleus fiber can have up to 800.

$\textbf{\large{\red{Question 8}} }$

$\dashrightarrow$voluntary muscle know as skelton muscle because they are under our conscious control and for most part , they attach to bones and make them move .
