Multiple Choice
Which of these statements about skeletal muscles is false?
A
Skeletal muscles are under voluntary control.
B
Skeletal muscles are attached to bones by tendons.
C
Skeletal muscles can contract without nervous stimulation.
D
Skeletal muscles are striated in appearance.
Verified step by step guidance
1
Understand the characteristics of skeletal muscles: Skeletal muscles are known for their voluntary control, meaning they contract when we consciously decide to move them.
Recognize the role of tendons: Tendons are strong connective tissues that attach skeletal muscles to bones, allowing for movement when muscles contract.
Identify the appearance of skeletal muscles: Skeletal muscles are striated, which means they have a banded appearance due to the arrangement of actin and myosin filaments.
Consider the requirement for nervous stimulation: Skeletal muscles require nervous stimulation to contract. This is a key feature that distinguishes them from cardiac muscles, which can contract without direct nervous input.
Evaluate the statements: The false statement is 'Skeletal muscles can contract without nervous stimulation,' as skeletal muscles need a signal from the nervous system to initiate contraction.
