fibres located in inner walls of reproductive tract,
(1) a & b only
(2) c & d only
(3) a, b &d
(4) a, b, c&d
Plz answer ​

Answer 1

Option a) and b) reflects the features of muscle fibers located in the inner walls of the reproductive tract.

• Human muscles are formed by specialized enlarged cells called muscle fibres. Muscle fibres are also called myofilaments.

• Muscles are classified into two types 1) Skeletal muscles or striated muscles

2) Smooth muscles or Visceral muscles.

• Visceral muscles or smooth muscles found in the inner walls of the reproductive tract.

• The sarcolemma is not present in these muscles and they are bounded by a thin plasma membrane.

• They are uninucleate. Muscle fibers or myofibrils are unstripped hence called nonstriated muscles.

Answer 2

Option a,b are correct

Explanation:

• Sarcomere are are present in the skeletal muscle that is absent in reproductive tract as the inner reproductive tract consists of 3 smooth muscle called myometrium and outer and inner longitudinal layer and circular layer present between them.
• Nucleus is present as it contain cell's genome and liner DNA.
