Exam 1: Family Focused NursingHuman Reproduction, Sexuality, and Genetics

4 phases of sexual response cycle - ______ ______ of _____ _____ _____: -excitement phase -plateau phase -orgasmic phase -resolution 8-11 - development of secondary sex characteristics in response to hormonal changes; marked increase in estrogen in girls between ages _____________ 17 - both males and females usually sexually mature by age _____, but this does vary 99%; 500 - 2 key findings: all humans are greater than ______ identical at the DNA level; and there are only about 20, ________ genes in the human genome autosomal recessive - _______ ________: Heterozygous individuals have only one variant allele and are unaffected clinically because their normal gene (wild-type allele) overshadows the variant allele. They are known as carriers of the recessive trait. For the trait to be expressed, two carriers must each contribute a variant allele to the offspring (see Fig. 3-3, C). The chance of the trait occurring in each child is 25%. Most recessive disorders tend to have severe clinical manifestations. breasts - ________: secondary sex characteristic that develops during puberty in response to estrogen and progesterone. Cyclic hormonal changes lead to regular changes in tissue to prepare for lactation when fertilization and pregnancy occur. cervix - ________: lower part of uterus where there is an opening (cervical os) clitoris - ________: erectile tissue that becomes engorged during sexual excitation. It lies anterior to the urethral meatus and the vaginal orifice and is usually covered by the prepuce. stimulation is an important part of sexual activity for many women. embryonic homoglogs - the glans clitoris and glans penis are _________ __________ epididymis - ________: is a comma-shaped structure located on the posterosuperior aspect of each testis within the scrotum. It is a long, tightly coiled structure that measures about 20ft in length. This transports sperm as they mature. Sperm exit the ______ through a long, thick tube known as the ductus deferens or vas deferen
