-OUTER Circular smooth muscle.*Notice how there is change in INNER &OUTER in Kidney versus the GI Tract.These muscles are used for Peristalsis in orderto siphon urine from kidney to bladder. Adistended bladders apical cells are flattened.-Contains Adventitia.Urinary BladderRugae: Innermost, & are folding’s of Mucosa. Ifno Rugae are present, bladder is distended.Mucosa → SubmucosaDetrusor Muscleremainsrelaxedto allow thebladder tostore urine, andcontractsduringurination torelease urine.Urinary Bladder Muscularis:
P a g e|54-Inner&Outerconsist ofLongitudinal Smooth Muscle.-MiddleisCircular Smooth Muscle.UrethraThin walledmuscular tube.MostlySTRATIFIEDCOLUMNAR.Prostatic,Membranous,Penile.Surrounded by Urogenital Diaphragm: also calledSphincter Urethae, & is skeletalmuscle thatcloses urethra voluntarily allowing tohold back from urinating.
P a g e|55Unit 15: Male Reproductive TissuePrimary Sex Gonads:Males: TestesTestesEnveloped in Scrotum: Also called scrotal sac.Primarily Integumentary Tissue.Subdivided into Lobules consists of:-Seminiferous Tubules:Creation of Spermatozoa.-Epididymis: single,tightly-coiled tubeconnecting efferent ductsfrom rear of each testicle toits vas deferens.-Vas Deferens, also calledDuctus Deferens: transportsperm from the epididymisto the ejaculatory ducts in anticipation ofejaculationLeydig Cells: Also called Interstitial Cells,secrete Androgens, &found in betweenseminiferous tubules.Sertoli Cells:nourishes developing spermcells through stages of spermatogenesis.Covered by:-Cremaster Muscle,composed of SkeletalMuscle. (Yo-Yo Effect)-Dartos Tunic,composed of SmoothMuscle. (Wrinkling Effect)Angiology:-Testicular Arteries: supply blood.-Pampiniform Plexus: drainage of blood.Spermatogenesis
P a g e|56Spermatogonia (Stem Cell) → Primary Spermatocyte (Mitosis) → SecondarySpermatocyte (Meiosis) → SpermatidsSpermiogensisSpermatids → Spermatozoa Spermatozoa:Head: Also called acrosome whichcontain enzymes.Middle Piece:Contains many mitochondria.Flagellum: Tail-like (Motility)Reproductive TractEpididymis: Head, Body, Tail.Functions in gauging composition of tubular fluid,recycling & functional maturation of spermatozoa.Urethra-Shared Structure: Semen & Urine.-True Urogenital Purposes.Penis & Accessory GlandsGlans:Anterior, or front most part of CorpusSpongiosum.Covered by Prepuce.Corpus Spongiosum, & Corpus Cavernosum areboth erectile tissue components of the penis.Seminal Vesicle: 60% of Semen Volume:-Alkaline Fluids: Buffer for Penile Urethra,control pH due to Urine interaction.-Fructose: Used for ATP.Prostate: 33% of Semen Volume.-Citrate-Acid Phosphatase
P a g e|57-HyaluronidaseUnit 16: Female Reproductive TissueOrgansOvaries, Uterine Tubes (Fallopian Tubes), Uterus, VaginaOvariesCorpus Luteum:develops from follicular cells surrounding the ovarian follicle duringthe luteal phase of mensus, followed by release of a secondary oocyte from thefollicle during ovulation. While the oocyte traverses the Fallopian tube into theuterus, the corpus luteum remains in the ovary. If pregnancy occurs, corpus luteumsustains pregnancy.
