Correct Option
The correct option is
Cardiac Muscle : Uninucleate
Explanation
Muscular tissue in animals is classified into three primary types: Skeletal, Smooth, and Cardiac. These are differentiated based on their structural appearance (presence of striations), the number of nuclei per cell, and their functional control (voluntary or involuntary).
Option Analysis
- Option (a) is Incorrect: The term "Striated Muscle" primarily refers to skeletal muscle. Skeletal muscles are under the conscious control of the nervous system, making them voluntary. While cardiac muscle is also striated, it is distinct from the general category of skeletal muscle.
- Option (b) is Incorrect: Smooth muscles (non-striated) are found in the walls of visceral organs such as the stomach, intestines, and blood vessels. Their movements are not under conscious control; therefore, they are involuntary.
- Option (c) is Correct: Cardiac muscles are found exclusively in the heart. Structurally, they are striated and branched. Unlike skeletal muscles, cardiac muscle cells are typically uninucleate (possessing a single central nucleus). They function involuntarily.
- Option (d) is Incorrect: Skeletal muscle fibers are long, cylindrical, and formed by the fusion of myoblasts. This results in a syncytium, meaning they are multinucleate (containing many nuclei).
Key Takeaway
Skeletal Muscle: Striated, Voluntary, Multinucleate.
Smooth Muscle: Non-striated, Involuntary, Uninucleate.
Cardiac Muscle: Striated, Involuntary, Uninucleate (and branched).
