Refer to Section 38.3 (p. 1012) of the Glencoe Biology for Questions 1, 4 and 5 – the rest should be considered Review.
1. Birth occurs in three recognizable stages. Summarize what happens during each:
I. Dilation of the Cervix
II. Expulsion of the Baby
III. Placental Stage
2. What is the cervix and where is it located?
3.Draw a diagram to summarize the endocrine event
involved in the release of growth hormone. If you need
help, this hormone is described on page 1013.
4. Describe where/how human growth hormone more
specifically works.
5. Growth and development occur over many stages. Four of the most general stages are infancy, childhood,
adolescence and adulthood. Summarize the general, distinct characteristics of each stage:
I. Infancy
II. Childhood
III. Adolescence
IV. Adulthood
6. What is the timing (sequence/approximate days) of the three menstrual phases plus ovulation over the 28-day cycle?
7. Summarize key information about each hormone in the table below by circling the endocrine gland and stage(s) at
which the hormones are released:
Hormone
FSH
LH
Estrogen
Progesterone

8. Define endometrium:
9. Describe what changes happen to/within the ovaries over the 28-day cycle:
10. Describe what changes happen to/within the oviducts over the 28-day cycle:
11. Describe what changes happen to/within the uterus over the 28-day cycle:
12. How does spermatogenesis differ from oogenesis?
13. How do haploid cells differ from diploid cells?
