Q

What happens in the menstrual phase of the uterus?

A

Arterioles in the stratum functionalis undergo constriction, depriving the tissue of blood that results in tissue breakdown, bleeding and tissue sloughing

Q

How is the vagina lubricated?

A

By mucous from the cervical glands and fluid from thin-walled blood vessels of the lamina propria

22
Q

What is skin which contains highly oblique hair follicles overlying a substantial subcutaneous fat pad?

A

Mons Pubis

23
Q

What is an extension of mons pubis that is rich in apocrine sweat glands and sebaceous glands?

A

Labia Majora

24
Q

What is thin skin flaps, lack subcutaneous fat and hair follicles, rich in vasculature and sebaceous glands, keratinised epithelium that extends into opening of vagina to the hymen and transitions to non-keratinised stratified squamous epithelium

A

Labia Minora

25
Q

What contains 2 tubes of erectile vasculature tissue, covered by a fibrocollagenous sheath and covered by skin with rich innervation and a thin epidermis?

A

Clitoris

26
Q

How many lobes is the secretory tissue of the breast made up of?

A

15-25 lobes

27
Q

What does each lobe of the secretory breast consist of?

A

A compound tubule-acinar gland which drains via a series of ducts leading to the nipple

28
Q

What do terminal ductules lead into?

A

Intralobular collecting duct

29
Q

What does the Intralobular collecting duct lead into?

A

Lactiferous duct

30
Q

What does the lactiferous duct lead into?

A

Nipple through the lactiferous sinus

31
Q

What covers the nipple?

A

Highly pigmented keratinised squamous epithelium

32
Q

Does the nipple have a core of dense connective tissue or dense irregular connective tissue?

A

Dense irregular connective tissue

33
Q

What is the lactiferous duct lined with?

A

Stratified squamous epithelium but deeper is is lined with stratified cuboidal epithelium

34
Q

What are the changes in the breast during menstrual cycle in the luteal phase?

A

Epithelial cells increase in height, the lumina of the ducts become enlarged with small secretions present

35
Q

What changes occur in the breast in the first trimester of pregnancy?

A

Elongation and branches of smaller ducts, proliferation of epithelial cells of the gland and myoepithelial cells

36
Q

What changes occur in the breast in the second trimester of pregnancy?

A

Glandular tissue continues to develop, secretory alveoli differentiation, infiltration of plasma cells and lymphocytes int he nearby connective tissue

37
Q

What changes occur in the breast in the third trimester of pregnancy?

A

Secretory alveoli maturation continues, development of extensive rER

38
Q

During pregnancy what stimulates proliferation of secretory tissue and fibrocartilage-fatty tissue which becomes sparse?

A

Oestrogen and progesterone

39
Q

What is the composition of human breast milk?

A 
88% water
1.5% protein
7% carbohydrate
3.5% lipid
Small quantities of ions, vitamins and IgA antibodies
40
Q

Most of the volume of the ejaculate in derived from what?

A

Seminal vesicles and the prostate glands

41
Q

What does the bulbourethral glands do?

A

Contribute a clear fluid that is released before ejaculation which helps lubricate the urethra

42
Q

What are the 3 segments of the urethra?

A

Prostatic, membranous and penile urethra

43
Q

What forms the ejaculatory duct?

A

The duct form the seminal vesicle joins the vas deferrers

44
Q

What are the spaces in the prostate lined with?

A

Heterogeneous secretory epithelium

45
Q

What lines the urethra?

A

Transitional epithelium

46
Q

What does the prostate produce?

A

A watery fluid that composes 1/3rd of the ejaculate

47
Q

The prostate gland is divided into which 3 regions?

A

Transitional zone, central zone and peripheral zone

48
Q

What has the urethra running through it?

A

Corpus Spongiosum

49
Q

How many corpora cavernosa is there?

A

2

50
Q

What is the difference between the Corpora cavernosa and corpus spongiosum?

A

Corpus spongiosum contains more connective tissue that the cavernosa and so has less erectile function to aid the passage of semen through the urethra

51
Q

What is the penile urethra lined with?

A

Stratified columnar epithelium and then non-keratisised stratified squamous near the tip of the penis

52
Q

What are within the blood sinuses in erectile tissue?

A

Helicine arteries
