OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

NOTE: DUE TO POTENTIAL COPYRIGHT INFRINGEMENTS, THE SLIDES HAD BEEN TAKEN OUT BY OWNER. SLIDE 1 - MEN’S BODIES - Study textbook as well as lecture notes - Will go into textbook material that was not covered in lecture notes SLIDE 2 - Testicles are located into scrotum - Testicles are the site of sperm production - Penis: site of sperm release - For women, maturity of egg happens once a month during menstrual cycle - For men, eggs are constantly being produced once puberty occurs SLIDE 3 - The foreskin can move around the glans (head of the penis) - Frenulum has lots of nerve endings (flatten region next to indentation *corona*); involved in arousal - The shaft is the length of the penis - Corpus spongiosum: makes up the shaft and it’s like sponge like structure SLIDE 4 - Within the gland, there’s a tube (urethra) for the release of urine and sperm rd - Within the shaft, there’s 3 erectile structures; one is a pair and there’s a 3 structure - Corpus cavernosum is the pair (on each side of the shaft) and there’s the single spongiosum and within that is the urethral tube - Corpus spongiosum extends into the glands and increases (spreads out) - Corpus cavernosum is surrounded by white covering called tunica albuginea - There’s also muscle associated with this area and these are called ischiocavernosus and bulbospongiosus muscles assist with erection and ejaculation - As we move up, there’s the prostate gland and it’s located underneath bladder and it hugs the urethra SLIDE 5 - Balanitis: leads to discomfort - Phimosis: - Paraphimosis: limited movement SLIDE 6 - Trace movement of sperm - Semen contains lots of chemicals as well as sperm - Scrotum sits behind the penis and it contains two testicles; lots of sweat glands and it’s covered by hair; sweat glands help regulate temperature, sperm is produced at a temperature lowered than body temperature, that’s why scrotum is located outside of body SLIDE 7 - Epididymis: C shaped structure that hugs the testicles - Spermatic cord is thought of as a lifeline of the testes; it provides lot of nutrients - Cremaster muscle: called a striated muscle because it has stripes, dark and light bands, sling around each testes - Sperm thrive at optimal temperature (few degrees lower than body temperature) - If it’s too cold in environment, the cremaster muscle moves the scrotum to move closer to body to maintain the temperature (contract automatically) NOTE: DUE TO POTENTIAL COPYRIGHT INFRINGEMENTS, THE SLIDES HAD BEEN TAKEN OUT BY OWNER. - Vas deferens: closely connected to testicles and carry sperm away from epididymis - Blue and red coloured areas represent veins, arteries and neural tissues: getting nutrition from blood and to maintain temperature (transfer of heat from movement of blood) SLIDE 8 SCROTUM SLIDE 9 - Dominated by seminiferous tubules; occupy lobes of testes SLIDE 10 - SPERM DEVELOPMENT - meiosis: process that sperm goes through - Consequence: from double to half, from diploid to haploid SLIDE 11 - TESTIS AND EPIDIDYMIS - Sertoli cells produces peptide hormones - Leydig cells produces testosterone - Production and maintenance of sperm - After leaving seminiforous tubules, it’ll pass through network called rete testis, and from that the sperm will encounter the epididymis and then to vas deferens SLIDE 12 - DISORDERS OF TESTIS - Torsion is twisted (either in muscles or connective tissues) and should be treated quickly SLIDE 13 - There needs to be testis exam - Feeling around for no abnormality SLIDE 14 - The vas deferens that goes around the bladder and then down towards the prostate gland and then it joins the prostate and then the name changes - The vas deferens change into the ejaculatory duct and also seminal vesicles (adding to the semen) - Ejaculatory duct joins to the urethra so then the urethra can eject urine or semen - Prostate releases a cloudy fluid into the semen - Prostate increase in size when increase in age - Bulbourethral gland also adds secretion SLIDE 15 - When prostate becomes enlarged depending on various factors, it starts to make urination difficult SLIDE 16 DISORDERS OF THE PROSTATE SLIDE 17 - HUMAN SP
