Answer 1

Craniodorsal -> Caudo ventral
Urether
Urinary bladder
Deferent duct
Ampulla of the deferen duct
Body of prostate
Urethra with urethral muscle
Ishiocavernosus muscle
Bulbocavernosus muscle
Retractor muscle of penis

Question 2

Structures to mention on the testis

Answer 2

Ductus deferens
A.ductus deferentes
Cauda epididymis
Lig.testis proprium

Corpus epididydimis
Bursa testicularis

Testiculary A + V - Abd.aorta + Cadal Vena cava
Mesorchium
Plexus pampiniformis
Caput epidididymis

Question 3

Layers of the scrotum

Answer 3

○Cutis scrotis (Cant dissect)
○Tunica dartos (cant dissect)
●Fascia spermatica externa-Deep to tunica dartos
adherrent with tail of epididymis -> lig.scroti
●M.cremaster - derive from int.abd.oblique m.
•covered by fascia cremasterica
•attached to the lateral or dorsal surf. of the fingerlike process formed by tunica vaginalis
•Cremaster reflex - raises tunica vag. and brings testis abd epididymis closer to the ext.ing. ring.
•Follow dorsally to the the origin of int.obliquue.
•Wont see the muscle / covers testis
○Internal spermatic fascia (Cant see)
•Fused with the underlaying tunuca vaginalis
●Tunica vaginalis
An evagination of parietal peritoneum, passing through ing.canal into the scrotum.
- Distal part: Testis and epididymis
- Proximal part: Spermatic chord
Covered with tunica vaginalis visceralis, completely fill the tunica vaginalis parietalis

● Plica ductus deferentis
● Plica vasculosa
● Plica mesorchium

Question 4

Testis

Answer 4

Extremitas capitata
Extremitas caudata
Margi epididymis
Margo liber

Tunica albuginea - Tough, fibrous capsule of the testis. Contains superf branches of testicular a+v

Transect testis to show septs emptyes into mediastinum of testis.

Question 5

Ligaments to testis

Answer 5

Ligamantum cauda epididymis - tail to scrotum
Lig. testis proprium - Testis - tail
Lig.scroti - Cant dissect

Question 6

A.testicularis

V. testicularis

Answer 6

A:
From abd. aorta
-Runs with funiculus spermatuvus - enter head of epidydimis
- Gives of rr.epididymis
V: 
From caudal vena cava 
- Runs with a.testicularis, lympatics,nerves
- Forms plexus pampiriformis

Question 7

Funiculus spermaticus

Answer 7

Consist of:
A+V testicularia
Lympathics
Testicular plexus of nerves
Smooth muscles
Ductus deferens - Enclosed in plica serosa- mesoductus deferens

Question 8

A.testicularis

Answer 8

A.testicularis - From.abd aorta

• Runs ventrally over the inner lumbar muscles, passes along the lateral abd. wall - (Covered by visceral vaginal tunic. wich is continious with parietal tunic). To the internal inguinal ring, and as a part of spermatic chord it reaches the head of epididymis
• Gives if rr. epididymales

Question 9

V.testicularis

Answer 9

From left: From v.cava caudalis

Right testiular vein enters renal vein

Question 10

Bloodsuply scrotum

Answer 10

From A.pudenda externa - R.scrotalis + A.cremasterica to m.cremaster - ventral

Question 11

Bloodsuply testis

Answer 11

A.abdominalis - A.testicularis

V.testicularis - breaks up and forms a rich plexus.

Question 12

Blood supply epididymis

Answer 12

A.testicularis and rr.epididymalis
