Question
Chapter 27.1, Problem 3AYLO
Summary Introduction
To discuss:
The organs which are considered as primary and secondary sex organs; internal and external genitalia; how secondary sex characteristics differ from secondary sex organs.
Introduction:
The organ system which produces the gametes are said to be a reproductive organ system. Depends on the role and function exerted by the reproductive organs during reproduction it is classified as primary and secondary sex organs. Genital organs are the one which involved sexual activity in order to facilitate the reproduction.

Ejaculation is the discharge of semen from the erect penis.
The labia minora of the female genitalia are homologous to the body of the penis
Meiosis is unique to the gonads.

Explain how chromosomes influence the internal and outward development of the sexual anatomy (hormones and structures). Is there always a correlation between genetic and anatomical sex? What is the reason, or why not? Describe a situation or disorder in which the internal and exterior sexual anatomy of a person do not match and explain how this would occur. Describe how a binary (male/female) model of sex does not reflect reality. What would a more accurate model look like?arrow_forwardThe function of the pampiniform plexus is to cool the arterial blood flowing to the testes. produce erection and ejaculation. propel sperm and seminal fluid through the spermatic cord. prevent inguinal hernias.arrow_forwardWhich of the following is LEAST LIKELY a function of the male reproductive system?

- Which of the below is NOT a fallacy about human sexuality? Size of penis contributes to greater female sexual enjoyment. Simultaneous orgasms for both persons represent a superior sexual accomplishment. Direct stimulation of the clitoris is essential for the attainment of orgasms. Clitoral orgasms are better than vaginal orgasms.arrow_forwardFigure 43.15 Which of the following statements about hormone regulation of the female reproductive cycle is false? LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. Both progesterone and estradiol are produced by the follicles. Secretion of GnRH by the hypothalamus is inhibited by low levels of estradiol but stimulated by high levels of estradiol.arrow_forwardBut biologically speaking, what is "sex"?
