A student studies a diagram of striated muscle in a biology textbook.

Definition

Noun: * Striated Muscle: A type of muscle tissue characterized by a striped or banded appearance under a microscope. It is typically attached to bones by tendons and is responsible for voluntary movements of the skeleton.

Usage

• Striated muscle is under conscious control, allowing for deliberate actions like walking, grasping, or talking.
• This type of muscle is also known as skeletal muscle.
• The characteristic stripes are due to the organized arrangement of contractile proteins (actin and myosin) within the muscle fibers.

Examples

• The biceps in your arm is a striated muscle.
• Striated muscle contracts quickly and powerfully but tires relatively easily compared to cardiac muscle.
• Weightlifting is an exercise designed to strengthen striated muscle.

Advanced Usage

• Histological Identification: In biology and medicine, the term is used to describe muscle tissue based on its microscopic appearance, distinguishing it from smooth (non-striated) muscle.
• Neuromuscular Junction: Striated muscle requires a signal from a motor neuron at a specialized synapse called the neuromuscular junction to contract.

Variants and Related Words

• Skeletal Muscle (n): A direct synonym for striated muscle, emphasizing its common attachment to the skeleton.
• Voluntary Muscle (n): Another synonym highlighting that its contraction is consciously controlled.
• Striation (n): Refers to the striped pattern itself. "The striations of the muscle fiber are visible under high magnification."

Synonyms

• Skeletal muscle
• Voluntary muscle

Antonyms

• Smooth Muscle: Muscle tissue lacking striations, found in organs like the stomach and blood vessels, and controlled involuntarily.
• Cardiac Muscle: The striated muscle found only in the heart, which contracts involuntarily.

Related Phrases / Terms

• Muscle Fiber: The elongated cell that makes up striated muscle.
• Sarcomere: The basic repeating unit within a striated muscle fiber that gives it its striped appearance.
• Tendon: The fibrous connective tissue that attaches striated muscle to bone.
