Example Questions
Example Question #151 : Tissues, Organs, And Organ Systems
Which of these structures is not a part of the female reproducive tract?
Ovary
Fallopian tubes
Urinary bladder
Vagina
Uterus
Urinary bladder
The urinary bladder is not a part of the female reproductive tract. Rather, it collects urine created by the kidneys. The ovary produces the female gametes. The fallopian tubes transport the eggs from the ovary to the uterus each month. The uterus provides a location and the necessary nutrients to the fertilized egg that develops into the fetus. The vagina receives the penis during sexual intercourse and expels menstrual flow from the uterus.
Example Question #152 : Tissues, Organs, And Organ Systems
Which of these is not an action of estrogen in females?
Growth spurt during puberty
Development of the breasts
Development of secondary sex characteristics in females
Maturation of uterus, fallopian tubes, cervix, and vagina
Stimulating uterine contractions during pregnancy
Stimulating uterine contractions during pregnancy
Oxytocin is the hormone responsible for stimulating uterine contractions during pregnancy. All other answer choices occur via stimulation by estrogen.
Example Question #161 : Tissues, Organs, And Organ Systems
Which of these is not a result of testosterone activity in males?
Increased muscle mass
Pubertal growth spurt
Facial, body, and pubic hair growth
Deepening of voice
All of these are correct
All of these are correct
Testosterone has many functions in males. Others functions than those listed include: enlargement of genitalia, increased libido, decrease in subcutaneous fat in face, aggression, and increased oil production—which may cause acne. In females, testosterone primarily functions to increase sexual arousal.
Example Question #162 : Tissues, Organs, And Organ Systems
Which of the following structures does not contribute to the fluidity of semen?
Prostate gland
Pituitary gland
Seminal vesicles
Bulbourethral glands
Pituitary gland
There are three primary structures that contribute fluids to sperm in order to create semen in the body: the seminal vesicles, the prostate, and the bulbourethral glands. The pituitary gland has an impact on the development and maturation of sperm, but does not directly add fluid to semen.
Example Question #163 : Tissues, Organs, And Organ Systems
Which of the following is a function of the male reproductive system?
Production of sex hormones
Delivery of sperm to the female reproductive system
Production and storage of sperm, production of sex hormones, and delivery of sperm to the female reproductive system
None of these answers
Production and storage of sperm
Production and storage of sperm, production of sex hormones, and delivery of sperm to the female reproductive system
The male reproductive system has all of the functions indicated in the answer choices.
Example Question #164 : Tissues, Organs, And Organ Systems
Painful cramps during menstruation is known as which of the following?
Amenorrhea
Menarche
Dysmenorrhea
Mastodynia
None of these answers
Dysmenorrhea
Dysmenorrhea is a term used to describe painful cramps that are present during menstruation. In most cases, the cramps are cause by involuntary contractions of the uterus, which is a muscle. Amenorrhea describes the abnormal absence of a menstrual period. Mastodynia describes breast tenderness during menstruation. Menarche describes a female's first menstrual period.
Example Question #165 : Tissues, Organs, And Organ Systems
The discharge of sperm and semen from the male body is known as which of the following?
Transpiration
Ejaculation
Implantation
None of these answers
Fertilization
Ejaculation
Ejaculation is the act of ejecting sperm and semen from the male body. Fertilization and implantation are the first steps of pregnancy that occur inside the female body after sexual reproduction has begun. Transpiration is the evaporation of water from plant leaves.
Example Question #166 : Tissues, Organs, And Organ Systems
What hormone surges and causes the release of an egg from the ovary?
Estrogen
LH (luteinizing hormone)
Progesterone
Prolactin
FSH (follicle-stimulating hormone)
LH (luteinizing hormone)
At day 14 of a menstrual cycle, the LH surge begins, which causes the follicle to burst, resulting in ovulation. The LH surge is caused by a rise in estrogen, which causes the pituitary gland to release LH.
Example Question #167 : Tissues, Organs, And Organ Systems
Which of the following hormones is crucial for the maintenance of pregnancy?
FSH
LH
Progesterone
Cortisol
Estrogen
Progesterone
Progesterone ("pro-gestation") is responsible for the maintenance of a pregnancy. Initially, the corpus luteum secretes progesterone in preparation for pregnancy. Then, after fertilization, human chorionic gonadotropin (hCG) is released which causes the corpus luteum to keep secreting progesterone. The placenta takes over it's function after 6 weeks gestation.
