Question

Answer 1

they contain three anterior compartments biceps deschis and chillies and posterior compartments are triceps and brachii

Answer 2

Skeletal muscles are joined to the ends of the bone with the help of tissues called tendons.

They stretch across the joints followed by their attachment to the next bones.

The contraction and relaxation of the skeletal muscles are voluntary functions, that is, they are based on our will.

We can see, feel and control the working of skeletal muscles and they function at our wish.
