2 Mamma and perineum 乳房和会阴

3 Ⅰ.Mamma 乳房

4 The mamma is present in both male and female. However the mamma of male does not develop. So we just talk about the mamma of female.

5 The mammary glands begin to develop and grow rapidly at puberty. During pregnancy and lactation, they are developing and secreting milk to nourish newborn baby.

6 (1) The location and features of mamma

7 Areolar gland 乳晕腺 mamma Areola of breast 乳晕 nipple 乳头

8 (2)The structure of mamma

9 The mamma is composed of skin, subcutaneous fat, connective tissue and mammary gland.

10 nipple Areola of breast Skin of mamma adipose tissue of breast Lobule of mammary gland Lactiferous duct Lactiferous sinus Areolar gland

11 乳头 乳晕 乳晕腺 乳腺小叶 输乳管 输乳管窦 乳房脂肪体 乳房皮肤

12 nipple Sagittal section of female mamma adipose tissue of breast Lobule of mammary gland Lactiferous duct Lactiferous sinus Pectoralis major intercostales Orifice of Lactiferous duct Suspensory lig. of breast Fascia of Pectoralis major

13 胸大肌 胸大肌 筋膜 乳腺小叶 输乳管 输乳管窦 乳头孔 乳头 乳房脂肪体 乳房悬韧带

14 Ⅱ.Perineum 会阴 1. The conception of perineum

15 The perineum has broad and narrow senses of perineum. The broad sense of perineum means the all soft tissues that close the inferior orifice of the pelvis. The perineum in anatomy is the broad sense of perineum.

16 The narrow sense of perineum means the soft tissue structure between the external genital organs of female and anus, it is also called obstetrical perineum ( 产科会阴 ).

17 2.The parts of perineum (1)Urogenital triangle (2)Anal triangle

18 Urogenital triangle Anal triangle Ischial tuberosity Broad sense of perineum

19 Urogenital triangle Anal triangle Ischial tuberosity Broad sense of perineum

20 Urogenital triangle Anal triangle Ischial tuberosity Broad sense of perineum

21 尿生殖三角 肛三角 坐骨节结 广义会阴

22 Vaginal vestibule Orifice of vagina anus Lesser lip of pudendum Orifice of urethra clitoris Narrow sense of perineum (obstetrical perineum) Narrow sense of perineum

23 产科会阴 阴道口 肛门 狭义会阴 ( 产科会阴 )

24 ischiocavernosus Levator ani Sphincter ani externus Gluteus maximus Superficial transverse m. of perineum anus bulbocavernosus Ischial tuberosity Perineal central tendon deep transverse m. of perineum Ischioanal fossa

25 坐骨海绵体肌 肛提肌 肛门外括约肌 臀大肌 会阴浅横肌 肛门 球骨海绵体肌 会阴深 横肌 坐骨结节 会阴中 心腱

26 ischiocavernosus Levator ani Sphincter ani externus Gluteus maximus Superficial transverse m. of perineum anus Ischial tuberosity Perineal central tendon Inferior fascia of urogenital diaphragm Ischioanal fossa Sphincter of vagina Bulb of vestibule

27 ischiocavernosus Levator ani Sphincter ani externus Gluteus maximus Superficial transverse m. of perineum anus Ischial tuberosity Perineal central tendon Inferior fascia of urogenital diaphragm Ischioanal fossa Bulb of vestibule

28 Vaginal vestibule Orifice of vagina hymen Lesser lip of pudentum Orifice of urethra Greater vestibular gland Head of clitoris Bulb of vestibule Orifice of greater vestibular gland

29 阴道口 尿道口 坐骨结节 坐骨海绵体肌 阴道括约肌 会阴浅横肌 肛提肌 臀大肌 肛门外括约肌 肛门

30 Levator ani Superior fascia of pelvic diaphragm Ischioanal (ischiorectal) fossa rectum inferior fascia of pelvic diaphragm Anal canal Obturator internus Internal pudendal artery and vein Sphincter ani externus

31 肛提肌 盆膈上筋膜 盆膈下筋膜 坐骨肛门窝 闭孔内肌 直肠 肛门外括约肌 阴部管 阴部内动静脉

32 Levator ani Superior fascia of pelvic diaphragm rectum Urethra of male Obturator internus coccygeus piriformis hiatus of pelvic diaphragm

33 肛提肌 尾骨肌 梨状肌 闭孔内肌 直肠 肛提肌腱弓 盆膈上 筋膜 男尿道 盆膈裂孔

34 Deep transverse muscle of perineum pelvic diaphragm Ischioanal fossa Superior fascia of urogenital diaphragm Superficial fascia of perineum Obturator internus inferior fascia of urogenital diaphragm Urinary bladder Urethra Bulb of urethra

35 肛提肌 盆膈下筋膜 盆膈上 筋膜 尿生殖膈下筋膜 尿生殖膈上筋膜 会阴深横肌 坐骨肛门窝 尿道球 会阴浅隙 浅会阴筋膜

36 vagina Orifice of vagina Levator ani Deep transverse muscle of perineum Superior fascia of pelvic diaphragm Ischioanal (ischiorectal) fossa Superior fascia of urogenital diaphragm Superficial fascia of perineum urerus

37 阴道 尿生殖膈 上筋膜 会阴深横肌 尿生殖膈下筋膜 坐骨肛门窝 前庭 球 浅会阴筋膜 会阴浅隙 阴道口 阴道前庭

38 The pelvic diaphragm ( 盆 膈 ) is formed by the levator ani, coccygeus together with the superior and inferior fasciae of pelvic diaphragm.

39 The ischioanal (ischiorectal) fossa( 坐骨肛门窝 ) is located between anus and ischial tuberosity. The lateral wall of the fossa is formed by obturator internus and the fascia of obturator, the medial wall is formed by the levator ani and

40 inferior fascia of pelvic diaphragm. The anterior boundary of the fossa is the posterior border of urogenital diaphragm, the posterior boundary is the inferior border of gluteus maximus.

41 The urogenital diaphragm ( 尿 生殖膈 ) is formed by the deep transverse muscle of perineum, sphincter of urethra together with the superior and inferior fasciae of the urogenital diaphragm.
