one, they fuse during development

the coelom

where do the eggs go after the coelom

the cloaca

lamprey ovary

Answer 8

Question 9

How many testes does a lamprey have and why

Answer 9

one TESTIS, it fuses during development

Question 10

path of the sperm

Answer 10

Sperm released into coelom, makes it
way out of the cloaca

Question 11

male testis

Answer 11

Question 12

The ___ of the shark is paired and extends for most of the length of the pleuroperitoneal cavity

Answer 12

opisthonephric kidney,

Question 13

In the FEMALE shark, the ___ drains urine to the cloaca

Answer 13

archinephric duct

Question 14

egg path in a shark

Answer 14

Eggs are released from paired ovaries into the coelom, make
their way through the ostium tubae (opening), through the falciform ligament, into the
paired oviducts (fertilization
happens here), are given a thin coating by the nidalmental gland,
then to the uterus (paired!)
where the eggs develop

Question 15

Shark has an
___ kidney

Answer 15

opisthonephric

Question 16

In the MALE, the ___ of the kidney is involved in
sperm transport.

Answer 16

archinephric
duct

Question 17

urine pathway male shark

Answer 17

Urine is drained
by the accessory urinary duct to
the cloaca.

Question 18

what part of the kidney functions in urine excretion

Answer 18

It is mainly the
posterior 3rd of the kidney that
functions in excretion of urine.

Question 19

parts of the opisthonephric kidney

Answer 19

Question 20

sperm pathway in sharks

Answer 20

Sperm is released from the testes,
moves through the ductuli
efferentes to the anterior part of
the kidney termed the epididymis,
which produces secretions. Sperm
moves through the archinephric
duct, a portion of which is wavy and
termed Leydig’s gland. The duct
then straightens and expands to
form the seminal vesicle (more
secretions) and finally the sperm
sac

Question 21

what does the clasper do

Answer 21

Clasper aids in sperm delivery. It is
inserted into the cloaca of female
during mating, with sperm released
from the urogenital papilla then
traveling along a groove. The
siphon contributes to seminal fluid

Question 22

cat egg pathway

Answer 22

Note, ovaries technically release
egg into coelom, but make their
way passed the fibriae of the
uterine tube, which leads to the
uterine horn. The two uterine
horns join to form the body
(bipartite uterus, has one cervix).

Question 23

cat urine pathway female

Answer 23

Paired kidneys produce urine,
which travels through the ureter
(this is the metanephric duct) to
be stored in the bladder, before
exiting via the urethra

Question 24

sperm pathway cat

Answer 24

testicles, where sperm are produced. From there, they travel to the epididymis, a coiled tube where they mature and are stored. Sperm then move from the epididymis into the ductus deferens (also known as the vas deferens), which carries them towards the urethra

Question 25

what structures are present in the kidney cortex

Answer 25

proximal and convoluted tubule, glomerular capsule

Question 26

what structures are present of the medulla,

Answer 26

loop of hence, collecting duct,

Question 27

what epithelium does the bladder, ureter, and renal pelvis have

Answer 27

transitional epithelium

Question 28

when is the bladder full

Answer 28

the epithelium is stretched and appears to be stratified squamous

Question 29

when is the bladder empty

Answer 29

the epithelium appears to be stratified cuboidal

Question 30

Semen: contains fluid from the ___, secretory products from ___

Answer 30

testis, epididymis, ductus deferens, and accessory glands

Question 31

semen ___ helps neutralize acidic environment of the ___

Answer 31

alkalinity, urethra and vagina.

Question 32

semen and prostaglandins

Answer 32

Prostaglandins can stimulate sperm motility and improve sperm penetration capacity in cervical mucus

Question 33

what is tunica vaginalis

Answer 33

a thin, serous membrane that surrounds the testis and epididymis in the scrotum

Question 34

tunica albuginea is one layer inner of

Answer 34

vaginalis

Question 35

follicle development

Answer 35

1. primordial follicles 2. early primordial follicle 3. late primary follicle 4. secondary follicle 5. mature Graafian follicle 6. ruptured follicle 7. corpus hemorrhagicium 8. corpus luteum 9. corpus albicans (if no pregnancy)
