Describe the blood testis barrier: what it is made of? what does
it separate? what it's for? Describe the
hypothalamus-pituitary-gonadal (HPG) feedback loop at puberty for
either male or female.
What types of molecules does the blood brain barrier (BBB) allow
to pass into the brain? What is blocked? How does this protect the
brain, but also leave it potentially vulnerable?
A) Where does the blood brain barrier (BBB) exist? (state where
it anatomically is) B) How are the capillaries at the BBB different
from capillaries at the blood-CSF barrier, include where this
blood-CSF barrier exists) C) Why do they have this
difference? D) Where does CSF flow as it circulates and what is its
function? What anatomy is involved with the return of CSF to
blood?
5. Some of the antimuscarinics can cross the blood–brain
barrier. What are the properties of a drug that would make them
more likely to cross the blood–brain barrier?
6. What symptoms could be reported as adverse side effects in a
drug that was able to cross the blood–brain barrier?
7. Some of the antimuscarinic agents are metabolised by the
cytochrome P450 enzymes. Drawing on your knowledge of these
important metabolising enzymes, explain the effect of the
cytochrome P450 enzymes

1. What does the position of the testis tell you about
spermatogenesis? Can you follow the path that sperm take as they
exit the testis? Trace the vas deferens as it passes by the male
accessory glands. What does the placement of these glands tell you
about their contribution to the seminal fluid?
2. Is the morphology of the spermatozoa the same as
that of the human? Why do you think that sperm head morphology may
differ among organisms? What is...
describe the role role of the heart sending blood to the brain.
Please include the separate chambers, valve and autorhythmic fibers
in your description.

1. If you separate whole blood in a centrifuge, what layers do
you get? What is contained in each layer (give details)? Give a
brief statement as to the function of each thing you find in each
layer.
Describe how the internal structure of the ovary differs from
the internal structure of the testis and how these organs differ in
reproductive potential.
