Answer 1

ANS. 1. Five general functions of the musculoskeletal system -

1. provides structural support to the body
2. stores minerals and lipids in the body, especially calcium.

5. produce blood cells.

ANS. 4.

• The arm is having "striated muscles" which are voluntary in nature.
• stomach is having "unstriped muscles or smooth muscles" they are involuntary in nature.
• heart is having "cardiac muscle" they are striated in appearance but are involuntary in nature and coordinate as a unit due to interconnected intercalated discs.
