 testicular artery 
 pampiniform plexus of veins
 cremasteric artery,
sympathetic nerves
lymphatics of the testis and epididymis.

Question 3

role of epididymus and where is it

Answer 3

maturation and storage of sperm. its in the testes

Question 4

Answer 4

seminiferous tubules
tubica albuguinea - partitions between

where spermatogenesis occurs

Question 5

order from anterior to posterior the structure of the pelvis of male

Answer 5

penis
testes
(vas deferens loops around pubic symphysis and bladder)
pubic symphysis 
urinary bladder (below is the prostate)
seminal vesicles 
rectum

Question 6

role of seminal vesicles

Answer 6

secretes alkaline seminal fluid

Question 7

role of the prostate

Answer 7

secretes prostatic fluid

Question 8

journey of sperm testes to ejaculation

Answer 8

testes, epididymus, vas deferns, inguinal canal, seminal vesicles, ejaculatory duct, prostatic urethra, membranous urethra

Question 9

describe structure of the penis

Answer 9

2 corpus cavinosum with deep artery running through, posterior to this is one corpus spongiosum that has the urethra running through it.

holding all together is bucks fascia

Question 10

name and describe the two ligaments of the penis

Answer 10

suspensory ligament- connects erectile bodies to pubic symphysis, from deep fascia

fundiform - abdominal subcutanoud tissue. wrap around the penis like a sling from linea alba to pubic symphysis

Question 11

name and describe location of the three major blood vessels supplying penis and state what they come from

Answer 11

all from the internal pudendal artery from internal iliac
dorsal artery - most superficial runs into the head/glans of penis
deep artery - through corpus cavinosum
bulbourethral - most inferior and supplies spongiosum

Question 12

innervation of penis

Answer 12

Sensory and sympathetic innervation to the skin and glans penis is supplied by the dorsal nerve of the penis - pudendal
cavernous nerve - Parasympathetic innervation

Question 13

order from anterior to posterior the structure of the pelvis of female

Answer 13

pubic symphisis, bladder, uterus, rectum

Question 14

name and describe the 3 ligaments of the female pelvis

Answer 14

broad - extends from the sides of the uterus medially to the pelvic sidewalls laterally and the pelvic floor inferiorly
ovarian - connects the ovary to the lateral surface of the uterus
Suspensory - connects the ovary to the wall of the pelvis

Question 15

what ligament goes through the inguinal canal

Answer 15

round ligament - ligamentum teres

Question 16

roles of the pelvic bone

Answer 16

Transfer of weight from the upper axial skeleton to the lower appendicular components of the skeleton, especially during movement.

Provides attachment for a number of muscles and ligaments used in locomotion.

Contains and protects the abdominopelvic and pelvic viscera.

Question 17

difference between the male and female pelvis girdle

Answer 17

Women have :
A wider and broader
lighter in weight
An oval-shaped inlet compared with the heart-shaped
Less prominent ischial spines
A greater angled sub-pubic arch
A sacrum which is shorter, more curved and with a less pronounced sacral promontory.

Question 18

what is the origin of theroundl ligament and where is it

Answer 18

a remnant of the embryonic gubernaculum.

It originates at the points at which the fallopian tubes enter the uterus, and attaches to the labia majora, passing through the inguinal canal.

Question 19

describe the development of the testes

Answer 19

While the gonads arise in the upper lumbar region, they are each tethered to the scrotum or labia by the gubernaculum – a ligamentous structure formed from mesenchyme.

As the body of the fetus grows, the testes become more caudal. They pass through the inguinal canal around the 28th week, and reach the scrotum by the 33rd week. During their descent, the testes retain their original blood supply, with the testicular arteries branching from the lumbar aorta.

The scrotal ligament is the adult remnant of the gubernaculum.
