Flashcards in Anatomy and Development Deck (24):
1

Anterior to Posterior

Vein, Artery, Ureter

2

Sinus contains

pelvis, fat, nerves, artery, and vein

3

Cortical Nephrons

Only dip into very superficial part of medulla

4

Juxtamedullary Nephrons

Dip down into medulla near the papilla

5

Hydropnephrosis

Accumulation of urine in kidney, can be congenital or obstructive
- dilation of calyces, pelvis, and ureter

6

Trail of vessels in kidney

Renal Artery --> segmental artery --> interlobar artery --> arcuate artery --> interlobular artery --> afferent arteriole --> efferent arteriole --> interlobular vein --> arcuate vein --> interlobar vein --> renal vein

7

Adult PCKD

HTN and worsening renal failure after 3rd decade of life
multiple cysts in all areas of parenchyma

8

Location of kidneys on posterior wall

T11-T12

9

Venous drainage from kidneys

R renal vein --> directly into IVC
L renal vein --> receives L gonadal vein --> IVC

10

Respiratory epithelium and glands form from what tissue?

endoderm

11

CT, cartilage, and smooth muscle of trachea

splanchnic mesoderm

12

Tracehoesophageal folds

divides trachea and esophagus with septum

13

Laryngeal cartilage

Neural crest cells

14

Laryngeal muscles

myoblasts, innervated by vagus nerve

15

Tracheoesophageal fistula

abnormal communication between trachea and esophagus
can result in polyhydramnios

16

Visceral pleura

splanchnic mesoderm

17

Parietal pleura

somatic mesoderm

18

Azygos lobe of lung

superior lobe of right lung grows medial to azygos vein instead of lateral

19

Lung hypoplasia

can be from oligohydramnios
can be from congenital diaphragmatic hernia --> GI contents obliterates lung cavity

20

Lung Development Stages

1. Pseudoglandular period (6-16 weeks) - ductal elements develop --> not compatible with life
2. Canalicular period (16-26 weeks) - respiratory passageways develop, vascularization occurs --> respiration possible
3. Terminal sac period (26-birth) - Type I pneumocytes form (squamous epithelium), Type II pneumocytes line alveoli and secrete surfactant

21

Maternal glucocorticoid treatment?

Enhances lung development and surfactant production

22

Respiratory Distress Syndrome

deficiency in surfactant
protein-rich, fibrin-rich exudate

23

Phrenic and vagus relationship to root of lung?

Phrenic --> anterior
Vagus --> posterior

24

RALS

Right Pulmonary Artery --> Anterior to Bronchi
Left Pulmonary Artery --> Superior to Bronchi
