Finals Flashcards
Involves organogenesis, proliferation, and specialization
Embryogenesis
Envelopes oocyte
Zona pellucida
Germ cell lineage undergoes a series of complex development
Gametogenesis
What are the result of gametogenesis
Spermatozoa and oocyte
What are the tunics of testes?
T. Vaginalis, T. Albuginea, T. Vasculosa
Functional unit of testes.?
Seminiferous tubule
How many lobules are there per testes?
250 lobules
Collecting reservoirs for the sperm?
Rate testes
Conduct sperm from rote to epididymis
Efferent ducts
Sperm transports protect, and store
. Epididymis
Storage prior to ejaculation
Vas/ductus deferent
Sperm delivery
Ejaculatory duct
Common passageway of reproductive and urinary
Urethra
For sperm mobility and viability
Seminal vesicle
For sperm motility
Prostate gland
Lubrication & neutralization of sperm
Bulbourethral gland
Chronological order of spermatogenesis
Spermatogonia- primary spermatocyte- secondary spermatocyte -spermatid- spermatozoa
Types of spermatogonia and define each
Spermatogonia type A- eccentric, rounded nucleus
Spermatogonia type B- centric, rounded nuclei
Reserve stem cells
Type A dark (ad)
Renewing stem cells
Type A pale (ap)
Lie in the cell layer luminal to spermatogonia.appear larger than spermatogonia
Primary spermatocyte
Threadlike appearance of chromosomes
Leptotene
Bouquet & umbrella configuration of chromosome
Zygote
Longitudinal contraction of chromosome
Pachytene
Metaphase, tell, and of first meiotic division
Diplotene
Undergo meiosis 2 to give rise to spermatid
Secondary oocyte
Haploid round spermatids complete develops to become spermatozoa
Spermatogenesis
Adult sperm with head, neck, tail
Spermatozoa
Sustentacular/nurse cells
Sertoli cells
AOT of Sertoli cell?
A - support & nourish spermatogenesis O- within ST t- developing sperm cell in St
Loc in between of ST; polygonal cell
Leydig cell
AOT of Lydia
A - produce & secrete testosterone O interstitial tissue t- ST
Consist of oocyte surrounded by a single layer squamous
Primordial follicle
Central oocyte surrounded with single layer which became cuboidal
Primary follicle
Prenatal follicle with 2-10 layers of cuboidal low columnar cells
Secondary follicle
AOT of luteinizing hormone
A - ovulation and hormone for production for pregnancy O- pituitary gland t- ovaries, serial cells
AOT of FSH
A-spermatogenesis (male) & follicular dev. (Female) O- pituitary gland t- ovaries & Sertoli cells
Liquid in the antrum (Graafian follicle)
Liquor follicle / follicular fluid
The cavity that suspends follicular fluid?
Antrum
Surrounds the antrum
Membrane granolas
Granolas cells surrounding oocyte
Cumulus oophorus
Separates theca cells from granulosa cells; steroid producing cells
Theca interna
Produce extracellular matrix factors such as collagen
Theca externa
Transient endocrine gland
Corpus luteum
Secretes estrogen
Theca lutein cells
Secrete progesterone
Granulosa lutein cells
Scar on the surface of ovary & remnant of ovulation
Corpus albicans
How many mature ovum and polar body would be produced in oogenesis?
1 mature ovum and 1 polar body
The product of spermatogonia?
8 mature sperm cells
