Question

Which is a false statement about skeletal muscle? 1) A myofibril is composed of multiple muscle fibres. 2) Most skeletal muscles attach to bones by connective tissue called tendons. 3) Each thick filament is surrounded by thin filaments. 4) A cross arm is a portion of the myosin molecule.

Answer 1

Answer:

option 1

Explanation:

A muscle fiber is composed of multiple myofibril or myofilament

Answer 2

The statement 'A myofibril is composed of multiple muscle fibres' is a false statement, so option 1 is the correct answer.

• Skeleton muscles connect the bones and allow us to perform different types of movements and functions.
• Skeletal muscles are voluntary, it means we can control the working of skeletal muscle.
• Skeletal muscles present in an organism and join by tendons to bones of the skeleton.
• The muscle cells of skeletal muscles are longer than any other type of muscle tissue and they are known as muscle fibres.
