Anatomy 28-Reproductive

Terms in this set (25)

34. List the functions of the reproductive system
Produce gametes (sperm, oocyte) and sex hormones (estrogen, testosterone, progesterone)
35. Describe the location of the perineum and distinguish between the urogenital and anal triangles
A diamond-shaped area between the thighs circumscribed anteriorly by the pubic symphysis, laterally by ischial tuberosities and posteriorly by coccyx

Urogenital triangle contrains the clitoris, urethral and vaginal orifices in females and base of penis and scrotum in males

Anal triangle contains the anus of both
36. Identify the primary and secondary sex organs in a female
Primary: Ovary
Secondary:Ducts to carry gametes away from gonads towards site of fertilization
37. Describe the position, support, and internal areas of the ovaries
Position: In pelvic cavity lateral to uterus
Support: they are anchored by the mesovarium and the broad ligament
Internal: within there are many ovarian follicles which support and oocyte
38. Identify the segments and tunics of the uterine tubes
Infundibulum- has fimbriae
Ampula-secondary oocyte fertilization happens here
Isthmus-extension of the Ampula
Uterine part- extension of the Isthmus
Mucosa-ciliated epithelium Muscularis-smooth muscle. Serosa
39. Discuss the shape, position and function of the uterus
Pear shaped, is normally anteverted
Function:Implantation of fertilized oocyte
Nourishment, support, protection of embryo
Ejects fetus at birth
Site of menstruation
40. Describe the regions and walls of the uterus
Fundus- broad superior region
Body- main part of uterus made of a thick wall of smooth muscle
Isthmus- narrow constricted inferior region superior to cervix- narrow inferior portion that projects into vagina
41. Describe the gross anatomy of the vagina
Birth canal. Inferior contains rugae, external opening called vaginal orifice. Very acidic
42. Identify female external genitalia
Collectively called vulva
Labia majora and minora
Vestibule
Greater vestibular glands
Clitoris w/glans/prepuce
43. Describe oogenesis and folliculogenesis
Oogenesis is the maturation of a primary oocyte to a secondary oocyte.

Folliculogenesis is the maturation of an ovarian follicle.
44. Explain how hormones control ovulation and aid in menstruation and pregnancy (if it occurs)
Follicle stimulating hormone stimulates oogenesis and folliculogenesis.
Lutenizing hormone causes ovulation

Estrogen and progesterone from ovarian follicles control development of endometrial lining to prepare for pregnancy
45. Identify primary and secondary sex organs in a male
Primary- teste
Secondary- set of ducts and tubules, group of glands, penis
46. Discuss the structure and function of the scrotum
Skin covered sac that holds the testes and first part of duct system outside body.
Raphe is seam running in middle
Dartos muscle elevates and descends testes
47. Describe the structure and contents of the spermatic cord
Originates at inguinal canal
Contains testicular artery, nerve cremasteric muscle, pampiniform plexus and vas deferens.

Allows structures to move between testes and body
48. Describe the location, structure and functions of the testes
Within scrotum
4 divided Lobules created by tunica albuginea, seminiferous tubules within oobules are the site of spermatogenesis
produces sperm and androgens
