LAYERS OF VASDEFFERENS
MUCOSA
MUSCULARIS
BULBOURETHRAL
GLANDS
Pea
sized
structures lie
proximal to
membranous
portion of
urethra &
empty into it
 Compound
tubuloalveolar glands that
structurally resemble mucus secreting
glands
 Lined by simple cuboidal epithelium
SEMINAL VESICLES
SEMINAL VESICLES
LAYERS OF SEMINAL
VESICLE
Mucosa
Muscularis
Adventitia
 Epithelium
lined by
tall nonciliated
columnar cells &
short round basal
cells
 Columnar cells have
morphology of
protein secreting
cells with well
developed rRER &
large secretory
vacuoles in the apical
cytoplasm
 Secretion
contains
fructose, along with
simple sugars, amino
acids, ascorbic acid &
prostaglandins
 Secretory function &
morphology of
seminal vesicles are
under the control of
testosterone
