Which muscle types appear striated under a microscope?

skeletal muscles only

cardiac muscles only

skeletal muscles and cardiac muscles

smooth muscles only

skeletal muscles and smooth muscles

Summary Introduction

Introduction:

A muscle tissue under a microscope can either have a striated appearance or a smooth appearance. The striated muscles as seen under a microscope consist of a series of bands or lines along the muscle fibers, which are formed due to the sarcomeres.

Explanation

Explanation/justification for the correct answer:

Option (c) is skeletal and cardiac muscles. Both skeletal muscles and cardiac muscles consist of actin and myosin molecules, which are arranged together to form the sarcomere. This sarcomere gives these tissues a banded or striated appearance under a microscope. Thus, both skeletal as well as cardiac muscles have a striated appearance. Hence, the option (c) is correct.

Explanation for the incorrect answers:

Option (a) is skeletal muscles only. This is an incorrect option as the cardiac muscles also have a striated appearance. So, it is an incorrect option.

Option (b) is cardiac muscle only...
