(aba) Afferent vessel (vas afferens). 



(abb) Efferent vessel (vas e/ferens). 



(ac) Capsular branches (rami capsulares). 



(ad) Straight arterioles (arteriolae rectae). 



(ae) Nutrient arteries of renal pelvis (Aa. nutricae pelvis 



renalis). 



Veins of Kidney (Venae renales). 



(a) Interlobar veins (Vv.'interlobares). 



(aa) Arciform veins (Vv. arciformes). 



(ab) Interlobular veins (Vv. interlobulares) . 



(ac) Straight venules (venulae rectae). 



(ad) Stellate veins (venae stellatae) (0. T. veins of Verheyn). 



Examine corrosion preparations of the renal blood-vessels in 

 the anatomical museum. 



Examine the adipose capsule (capsula adiposa). Does it 

 assist in maintaining the organ in position ? What is the ' ' para- 

 renal adipose body ' ' of Gerota ? 



Cut the blood-vessels and ureter some distance from the kid- 

 ney and examine 



(a) Lateral margin (mar go lateralis). 



(b) Medial margin (mar go medialis). 



(ba) Renal hilus (hilus renalis). 



(bb) Renal sinus (sinus renalis). 



(c) Anterior surface (fades anterior). 



(d) Posterior surface (fades posterior). 



(e) Superior extremity (extremitas superior). 



(f) Inferior extremity (extremitas inferior). 



(g) Muscular impression (impressio muscularis). 

 (h) Hepatic impression (impressio hepatica). 



(i) Gastric impression (impressio gastrica). 



Incise the kidney along its lateral margin, cutting through 

 its fibrous capsule (tunica fibrosa). Does it strip readily from 

 the surface of the kidney? What is the muscular tunic (tunica 

 muscularis) ? 



Divide the kidney into two symmetrical halves. (Of. Spalte- 

 holz, Fig. 637.) Study- 



(a) Cortical substance (substantia corticalis). 



(b) Medullary substance (substantia medullaris). 



(c) Renal lobes (lobi renales) (0. T. reniculi). 



(d) Renal pyramids (pyramides renales [Malpighii]) . 



(e) Base of pyramid (basis pyramidis). 



(f) Renal papillae (papillae renales). 



(g) Papillary foramina (foramina papillaria). 

 (h) Renal columns (columnae renales [Bertini]). 

 (i) Cortical lobules (lobuli corticales).
