striated muscle tissue
Học thuậtThân thiện
Definition
Noun: * Muscle tissue characterized by transverse stripes: This is a type of muscle tissue that appears striped or banded (striated) under a microscope due to the organized arrangement of its contractile proteins. It is primarily under voluntary control and is attached to bones, enabling movement.
Usage
- Striated muscle tissue is the primary component of skeletal muscles.
- The distinct bands in striated muscle tissue are due to overlapping filaments of actin and myosin.
- Damage to striated muscle tissue can result from intense exercise or trauma.
Examples
- Under the microscope, the striated muscle tissue showed clear alternating dark and light bands.
- Weightlifting helps to hypertrophy, or increase the size of, striated muscle tissue.
- The biopsy confirmed that the sample was striated muscle tissue, not smooth muscle.
Advanced Usage
- Histological identification: In biology and medicine, the term is used to precisely identify muscle type in tissue samples based on its microscopic appearance, distinguishing it from smooth or cardiac muscle tissue.
Variants and Related Words
- Skeletal muscle tissue: A near-synonym, though technically skeletal muscle is an organ composed of striated muscle tissue, nerves, and connective tissue.
- Voluntary muscle: A functional term for muscle composed of striated muscle tissue, referring to its typical control.
- Striated muscle (noun): Often used interchangeably with "striated muscle tissue" in a broader sense.
- Striation (noun): Refers to the stripe or groove-like pattern itself.
Synonyms
- Skeletal muscle (in common, non-technical usage)
- Voluntary muscle (functional synonym)
Antonyms
- Smooth muscle tissue (muscle tissue lacking striations)
- Cardiac muscle tissue (heart muscle, which is striated but involuntary)
Noun
- muscle tissue characterized by transverse stripes
