Answer 1

Answer:

A

Explanation:

Striped muscles are cylindrical and voluntary also known as skeletal muscles.

Answer 2

The correct solution is option a, Cylindrical, striped, skeletal and voluntary.

• Skeletal muscles are types of striated muscle tissue.
• It is multinucleated and unbranched. The nucleus is located peripherally.
• The shape of the muscle is cylindrical with blunt ends.
• They are voluntary in action i.e subject to conscious control. Examples are the movement of limbs, facial expressions, swallowing etc.
• These muscles are controlled by the somatic nervous system.
• Each skeletal muscle has a tendon at the end, that connects the muscle to the bone.
• The Presence of alternating dark and light bands are found which appears as striations because of the arrangement of sarcomeres.
• Striations are formed of myofibrils. The building block of myofibrils is actin and myosin proteins.
