SECONDARY OOCYTE AND OOGENESIS

Complete oogenesis results in the formation of:

• 1 ovum; 3 polar bodies

• 1 secondary oocytes;2 polar bodies

• 1 ovum; 3 secondary oocytes

• 1 ovum; 1 polar body

Oogenesis is the process in the ovary that results in the

production of female gametes. Which statement about

oogenesis in humans is false?

• Oogenesis begins before birth

• The process of oogenesis is completed when the egg cell

  is penetrated by sperm

• Oogenesis continues throughout the life of individual

• In oogenesis, unequal cytokinesis results in one single

  large daughter cell, which goes on to form the egg

What are the products of oogenesis in correct order?

• Oogonium →primary oocyte and first polar body → secondary oocyte and second polar body →ovum

• Primary oocyte → oogonium and first polar body → secondary oocyte and second polar body →ovum

• Oogonium → primary oocyte → secondary oocyte and first polar body →ovum and second polar body

  
  

  
  

• Ovum →primary oocyte and first polar body → secondary oocyte and second polar body → oogonium

Oogenesis can be define as

• production of ovum in ovary

• production of secondary oocyte in ovary

• production ovum in vagina

• production secondary oocyte in vagina

Oogenesis occur in

• uterus

• vagina

• cervix

• ovary

Which of the following statement true about secondary oocytes.

• may degenerated if no fertilization occur

• arrested at metaphase I

• haploid cell

• arrested at prophase I

Which one of the following is not diploid?

• germinal epithelial cell

• oogonia

• primary oocyte

• secondary oocyte

The second polar body is only made after fertilisation.

• True

• False

When does oogenesis begin?

• at birth

• before birth

• at the onset of adulthood

• at the onset of puberty
