Urinary & Reproductive Histology

What does the Macula densa sense

blood pressure

what function is it to regulate systemic blood pressure, glomerular blood flow and filtration rate

juxtaglomerular

renal corpuscle and the renal tuble are part of what

nephron

Distal convuluted tubule is under what control

hormonal control

The collecting system is in what

pyramids/medulla

finger like projections from podocyte

pedicels

line the outer surface of the glomerular cappillaries, forming final barrier that prevents tthe passage of large molecules, such as proteins, into the urine

podocytes

Brings blood and filtriate into glomerulus

afferent arteriole

phagocytic cells around glomerular capillaries

mesangial cells

exits blood without filtrate

efferent arteriole

produces renin

juxtaglomerular

what epithelium type is the proximal convuluted tubule

simple cuboidal epithelium

what epithelium type is the loop of henle thin

simple squamous

what epithelium type is the loop of henle thick

simple cuboidal

merge to form the renal papilla

collecting duct

calyces, renal pelvis, ureters, urinary bladder epithelium

transitional

Urethra epthelium near bladder for both male and female

Transitional

Urethra female epthelium away from bladder

non-keratinized stratified columnar

urethra male prostatic, membranous, spongy

pseudostratified or stratified columnar

navicularis fossa epithelium

stratified squamous

2-3 layers of smooth muscle: inner longitudinal, middle circular & outer longitudinal (only aprears in the lower 1/3 of …)

Ureter

detrusor muscle

bladder

produce sperm (spermatogenesis)

seminiferous tubulues

maturation of sperm

spermiogenesis

dense connective tissue capsule which thickens on the posterior side to form teh mediastinum testis

Tunica albuginea

produce testosterone

interstital cells (leydig cells)

support all spermatogenic cells physically and metabolically phagocytize debris/ endocrine roles affecting spermatogenis and fetal development of male reproductive tract

sertoli cells

how does sperm move to the epididymis

Seminiferous tubules, straight tubules, rete testis, efferent ductules, epididymis

rete testis epithelium

simple cuboidal

lined with pseudostratified columnar epithelium with long stereocilia

epididymis

leaves the scrotum and continues toward the prostatic urethra where it empties into the ejaculatory duct

ductus (vas) deferens

very thick muscularis with inner and outer longitudinal with a middle circular layer

ductus (vas) deferens

epididymal duct, ductus (vas) deferens, ejaculatory ducts epithelium

psuedostratified columnar

lined with simple or pseudostratified columnar cells rich in secretory granules

seminal (gland) vesicle

major energy source for sperm

fructose

stimulate activity in femal reproductive tract

prostaglandins

allows semen to coagulate after ejaculation

fibrinogen

located in the urogenital diaphragm

Bulbourethral (cowpers) gland

testosterone dependent secretory units surronded by smooth muscle and lined with mucus-secreting simple columnar epitehlium

bulbourethral (cowpers) gland

ovary epithelium continuous with mesothelum and overlaping a capsule of dense connective tissue (tunica albuginia)

simple cuboidal

uterine tubes epithelium distal part

ciliated simple columnar

uterine tubes epithelium proximal part of tube

Ciliated simple columnar epithelium

consists of type 3 colagen with abundent fibroblasts and ground substance

endometrium of uterus

uterus endometrium epithelium

simple columnar epithelium

simple columnar of endocervical canal to nonkeratinized stratified squamous epithelium

transformation zone

vagina’s epithelium

non-keratinized stratified squamous

richly vascular, hairless

labia minora

space between labia minora and encompasses the urethral and vaginal openings

vestibule

vestibule is paired with

greater vestibular (bartholin’s) gland
