level questions: Male Reproductive System

QuestionAnswer
Where are the Testes located?the testes are located in the scrotum
Define the scrotumthe scrotum is skin and superficial fascia that surrounds the testes
What muscles are connected to the Testes?- the Dartos muscle - the Cremaster muscle
Define the Dartos muscle and its functionThe dartos muscle is a layer of smooth muscle and is responsible for the wrinkling of scrotal skin
Define the Cremaster musclethe Cremaster muscle are bands of skeletal muscle surround the testes its function is to elevate the testes, allows sperm to move up the vast deferens
What encloses the testesThe tunica vaginalis encloses the testes
Define Tunica Vaginalisserous sac
What divides the testes into lobules?The tunica albuginea is a fibrous capsule that divides the testis into lobules
Where do the sperms get produced?Sperm is produced in the lobules found within the testes
Where does the sperm travelthe sperm travels through tubes or the Epididymis which is a comma shaped structure on posterior testes
How are the seminiferous tubules seperated?The seminiferous tubules are separated by areolar connective tissue
Define the function of spermatogenic cellsspermatogenic cells are sperm forming cells begin at puberty
What is the function of columnar sustentocytes?they are support cells
What do seminiferous tubules produce?Seminiferous tubules in the male testes continually produce new spermatogonia
What is spermatogoniadiploid germ cells
What occurs to the spermatogonia during meiosis?produce sperm (haploid male gametes)
What is the sequence of sperm formation?spermatogonium --> primary spermatocyte --> secondary spermatocyte --> spermatid --> immature sperm
What surrounds the seminiferous tubules?myoid cells
Function of myoid cellscontract rhythmically
What is the function of intersitial endocrine cells?secrete testosterone
What tissue make up the epididymispseudostratified columnar epithelium - contains cilia
How many days does it take for the sperm to pass all the tubules20
What is a spermatozoona mature sperm
Define the structure of a spermatozoonhead: contains DNA and an enzyme cap midpiece: mitochondria flagellum: allows movement
What is the acrosome?head portion of the mature sperm
What can be found inside the acrosome?nutritional lips and carbohydrates
Define the function of the urethrathe urethra carries sperm form the ejaculatory ducts to the "outside"
what are the 3 parts to the male urethra?- prostatic urethra - intermediate part of urethra - spongy urethra
Where do the seminal glands lielie on the posterior surface of the urinary bladder
Function of the seminal glandssecrete about 60% of the volume of semen
what does fluid found in semen contain- fructose (to nourish sperm) - substances to enhance sperm motility - prostaglandins - substances that suppress immune response against semen
Function of the prostrate glandencircles the prostatic urethra secretes about 25-30% of the seminal fluid act as a nutritional bio concentrator
What does the prostrate gland contain?- 20-30 compound tubuloalveolar glands - substances the enhance sperm motility - enzymes that clot and then liquefy semen
