The junction between two adjacent neurons is called:

Read the given Statements for skeletal muscles (i) Thin filaments are firmly attached to the Z - line . (ii) The light band is also called the I - band and contains mostly actin. (iii) A sarcomere is the functional unit of a myofibril between two adjacent A - bands . (iv) The central part of the thick filament , not overlapped by the thin filament is called the H - zone Which of these is/are CORRECT ?

The distance between two adjacent antinodes is

The portion between two successive Z-line is called

The region between two successive Z-discs is called a

Assertion: The portion of the myofibril between two successive Z-lines is considered as the functional unit of contraction called sarcomere. Reason: During contraction, l-bands get reduced whereas A-bands retain the length , thereby causing shortening of the sarcomere.
