Cards

Term
Blood supply to the Kidney
Definition

Abdominal aorta

Enter kidney by the Renal artery

Segmental arteries

Interlobar arteries

(-medullary junction)

Arcuate arteries

InterlobULar arteries

(supply Blood for filtration)

Afferent arterioles

(toward renal corpuscle)

Glomerulus

Efferent arteriole (ductile??)

(carries blood away)

→ cortical nephrons or juxtamedullary nephron

Peritubular capillaries or Vasa recta

InterlobULar veins

Arcuate veins

Interlobar veins

Renal vein

IVC

 

Term
Trace the pathway of waste form the glomerular capsule to the urethral orifice
Definition

PCT (proximal convuluted tubule)

Nephron loop

DCT(distal convoluted tubule)

Collecting duct

Papillary duct

Minor calyx

Major calyx

Renal pelvis

Ureter

Urinary bladder

Urethra

Term
Efferent arterioles branch (2 forks in the road)
Definition

1) Peritubular capillaries of cortical nephrons

 

2) Vasa recta of juxtamedullary nephrons

Term

Reproductive sys

Homologues

Definition

 

            Ovary & testis

=produce gametes & sex hormones

 

            Clitoruis & Glans of penis

=contain autonomic nervous sys axons that stimulate arousal & sexual climax feelings, erectile strucs w/ erectile tissue (homo)

 

            Labia majora & Scrotum

=Protect & cover some reproductive structures(homo)

 

            Vestibular glands & Bulb glands

=Secrete mucous for lubrication

 

Term

Perineum

landmarms

Definition

 

Synthesis pubis, Ishial tuberositys & coccyx

 

Term
Urogenital Triangle
Definition

 

Fem= vestibule (houses urethral orifice & vaginal orifice)

 

Male = scrotum & base of penis

 

Term

 

When temp is cold will elevate testis toward body 2 keep them warm

 

When hot these muscles relax allowing testes 2 lower away from body 2 keep cool

 

 

What muscle does this

(male)

Definition
by way of Dartous muscle & Cremastor muscle that runs along spermatic cord
Term

 

Pathway of Sperm

 

Definition

▒Semifernous tubules(sperm produced here)-

 

▒Efferent ductules-

 

▒Epidymis-

 

▒Vas deferens- Seminal vesicle duct –

 

▒Ejaculatory duct (same tissue lines it as above) – urethra(surrounded by prostate gland) –

 

▒Prostatic urethra (lined w/ transitional epi) –

 

▒Membranous urethra (columnar epi)(contains bulb glands),

 

▒Penile urethra (lined w/ proximally squdo strat colu epi & distally lined by stratified squamous epi 4 protect)-

 

▒Urethral orifice

 

Term
Spermatogenesis
Definition

Occurs w/in the semiferous tubules

 

-Spermatogonium: 2n=46 (diploid) undergo mitosis

-Primary spermatocyte: 2n= result of 1st M division

 

-Secondary spermatocyte: 2n= result of 2nd M division

Spermatids: (most mature)

Spermatozoa????

 


 

 

Term
Oogenesis
Definition

 

Ovarian Follicles

= oocyte surrounded by follicle cells


Primordial follicle

= primary oocyte (an oocyte thats stuck in the

first meiotic prophase)


Primary follicle

= primary oocyte surrounded by one or more layers of cuboidal follicular cells.

Secretes estrogen which stimulates changes in the uterine lining.


Secondary follicle

= primary oocyte, many layers of follicular cells, & fluid-filled space(antrum). 

Zona pellucida is a translucent structure that contains glycoproteins.

Corona radiate is the innermost layer of follicle cells. Secretes estrogen which stimulates changes in the uterine lining.


Vesicular follicle= secondary oocyte, #s layers of follicular cells, large crescent-shaped fluid filled antrum.

Secondary oocyte completes meiosis I

and is stuck in the second meiotic metaphase.


Corpus luteum: The remnants of the ruptured vesicular follicle. Does NOT contain an oocyte. Secretes sex hormones progesterone and estrogen.

(only in 1st 3 months of pregnancy, then the placenta does it)


Corpus albicans: White, connective tissue scar that is formed by the breakup of the corpus luteum. Most get resorbed. 

 

Term

Before the ovarian cycle what hormone is being produced?

 

 

Ovarian cycle

(3 phases)

Definition

Hypothalamus release GnRH,

which stimulates Anterior Pituitary

2 release FSH (follicle stimulating hormone)

& LH (Lutenizing hormone)

 

 

Term

Uterine (menstrual cycle)

 

& include hormone levels

Definition
Term

CPS question

 

 

During the follicular phase of the ovarian cycle:

FSH & LH r ____, the follicle finally matures 2 a _____, & the endometrium is ______.

Definition

Relatively high

 

Vesicular follicle

 

Building up

Term

CPS

 

Fertilization of egg in female

 

Sperm goes from (in female)

Definition

1) Oocyte ovulates from ovary

 

2) Enters body of uterus

 

3)Enters uterine tube

 

4)Fimbriae of infundibulum sweep oocyte inside

 

5)Travels thru isthmus

 

6)Travels thru ampulla of uterine tube

 

7) If fertilized implants into endometrium

 

SPERM

1) Body of uterus

2)Isthmus

3) Ampulla
