Histology of the Male Reproductive System Flashcards
Male role of reproductions
Produce sperm and deliver to female
Whats the role of male gonads?
Endocrine - produce testosterone
Exocrine - produce sperm
What are the gonads outside the body?
Temperature of the scotum is 34 C, which is more efficient for sperm
Sperm are nonfuncitonal at 37 C (body temp)
What are the steps of Spermatogeneis
Spermatocytogenesis
Spermigenesis
Spermatocytogenesis
Formation of spermatogonia to spermatocytes to spermatids
Spermigenesis
Maturation process - spermatids to spermazoa
What are the intersticular ducts?
Straight tubules
Rete testis
Efferent ductules
What are the Straight tubules?
Short, straight tubules
Lined only with Sertoli cells
At the very end, switch to cuboidal epithelium with underlying dense connective tissue
Rete Testis
Interconnected network of channels lined with cuboidal epithelium or low columnar epithelium with underlying dense CT
Efferent ductules
Lined with pseudostratified columnar epithelium with groups of nonciliated cuboidal cells with microvilli alternating with groups of taller ciliated cells, some circularly oritented smooth muscle cells can be found around these
Female role in reproductions
Production of eggs
Providing locations for fertilization and embryonic development
Role of Female gonads
Endocrine - produce estrogens and progestogens
Exocrine - Produce female gamete (ovum), and produce and ovulate a secondary oocyte
Estrogen
Growth
maturation of reproduction organs
cyclic changes in uterine mucosa
Uterine tube cell type
Simple Columnar epithelium
What are the 3 layers of the Uterus
Perimetrium
Myometrium
Endometrium
Perimetrium
Outer connective tissue layer of uteru
Myometrium
Middle and thickest layer of uterus
Bundles of smooth muscle connected by connective tissue containing blood vessels
Endometrium
Inner layer of Uterus
2 parts: basal layer, functional layer
Seminal vesicles
Highly torturous glands rich in secretory granules
Joins with ampulla of ductus defrens to form ejaculatory duct
Prostate gland
Collection of 30-50 tubuloalveolar glands embedded in a dense fibromuscular stroma
Empties into prostatic urethra
Bulbourethral glands
Compound tubuloalveolar glands
Empty into the proximal part of the penile urethra
Corpus Cavernosa
Paired ventral cylinders in the penis
Corpus Spngiosum
Ventral cylinder that covers male spongey urethra
What are the 3 types of ovarian follicles?
Primordial Follicles
Growing Follicles
Mature follicles
Theca folliculi
Sheath of connective tissue cells that develop from the stromal cells surrounding the developing folicle
What are the 2 parts of the Theca folliculi
Theca interna
Theca externa
Theca interna
Suboidal secretory cells that act in response to LH
Synthesize and excrete andorgens
Theca externa
Fibrous outer portion of theca foliculi
Corpus Luteum cell types
Granulosa Lutein cells
Theca lutein cells
Granulosa Lutein cells
Undergo hypertrophy and begin to produce progesterone
Theca lutein cells
Produce estrogens
