Anatomy final (Male Repro)

Male Reproduction 21 Removal of the foreskin from the penis is called 2/2

Circumcision

Male Reproduction Failure of testes to descend into the scrotum before birth is called

Cryptorchidism

Male Reproduction Which diagram represents a sperm that can unite with a normal egg to produce a zygote that will develop into a normal human male embryo?

2

Male Reproduction The scrotum is an important adaptation in human males because the optimum temperature for sperm development is

2-4 degrees below normal body temp

Male Reproduction Which diagram best represents the formation of a zygote that could develop into a normal human male?

4

Male Reproduction The human male reproductive system is represented in the accompanying diagram. Which structure produces cells that have the potential to become gametes?

A

Male Reproduction Base your answers on the accompanying diagram, which represents systems in a human male and on your knowledge of biology. Which sequence represents the path of sperm leaving the body?

A-C-G

Male Reproduction A fluid mixture called semen could contain

A: sperm cells B: secretions from the prostate gland C: secretions from the seminal vesicles (D: all of the above)

Male Reproduction In human males, sperm cells are suspended in a fluid medium. The main advantage gained from this adaptation is that the fluid

Acts as a transport medium for sperm

Male Reproduction The diagram shown represents the human male reproductive system. Which pair of letters indicates a structure that produces gametes and a structure that makes possible the delivery of gametes for internal fertilization, respectively?

B and D

Male Reproduction Base your answers on the accompanying diagram, which represents systems in a human male and on your knowledge of biology. Which structures aid in the transport of sperm by secreting fluid?

B and E

Male Reproduction Base your answer on the accompanying diagram and on your knowledge of biology. The letters in the diagram indicate structures present in a human male. Which structure produces the male hormone responsible for characteristics such as muscle development, deep voice, and gamete production?

E

Male Reproduction 15 Sperm is stored in the bulbourethral gland. 2/2

False

Male Reproduction Circumcision is necessary for normal male reproductive function.

False

Male Reproduction The male sex cell is called the ova.

False

Male Reproduction Base your answers on the accompanying diagram, which represents systems in a human male and on your knowledge of biology. Which structure has both reproductive and excretory functions?

G

Male Reproduction After sperm cells are deposited inside the female, the pathway they follow to reach the egg is from

K-I-H

Male Reproduction Sperm cells are suspended outside of the body cavity so as to

Keep them at a cool temp

Male Reproduction 23 Which of the following structures can be referred to as male gonads? 2/2

Testes

Male Reproduction Which hormone stimulates and controls the development of secondary sex characteristics in human males? 2/2

Testosterone

Male Reproduction Some body structures of a human male are represented in the diagram (see image). An obstruction in the structures labeled X would directly interfere with the

Transfer of sperm to female

Male Reproduction 18 The male external genitalia is comprised of the penis and scrotum. 2/2

True

Male Reproduction Millions of sperm are released per ejaculation.

True

Male Reproduction Sperm cells are produced in the seminiferous tubules.

True

Male Reproduction 4 The part of the male reproductive system that provides an optimum temperature for sperm production is the 2/2

Scrotum
