The protoplasmic segment of striated muscle fibre is termed as
Open in App
Solution
The correct option is A sarcoplasm
Sarcoplasm is the protoplasm of the striated muscle fibres which also contains numerous nuclei (multinucleated), mitochondria, sarcoplasmic reticulum excluding the myofibrils. Striated muscle fibre is long and unbranched. It is enveloped by sarcolemma.
The basic contractile unit of muscle fibre is called a sarcomere. It consists of two main protein components actin and myosin which helps in muscle contraction.
Metameres is the linear series of segments into which the body of the animal is divisible. In animals, metameric segments are referred to as metameres.
Neuromeres are the segments of the early developing brain. They are the segments of the neural tubes which establish the embryonic brain during development.
