reproductive system

• testes is connected to the trunk called spermatic cord
• seminiferous tubules and interstitial cells are responsible for actual function of testes
• spermatic cord is the connetion of body and testes
• seminiferous tubules is where the sperm cell is formed
• rete testes is the passageway in between the seminiferous tubule and epididymis
• ampulla is the terminal end of vas deferens
• prostatic urethra is surrounded by prostate gland
• membranous urethra begins in the prostate up until the base of penis (middle)
• spongy urethra runs along the entire length of penis
• sugat (fructose) and vitamin c will be use by the sperm cell as they travel to the vagina
• the male sex hormone is called testosterone
• shaft is the actual length of penis that we can see externally
• prepuce is excess skin in that is cut because of tradition
• glans penis is the tip or head
• in penis, there is spongy erectile tissue that makes the shaft hard; corpora cavernosoa amd corpus spongiosum
• corpora cavernosa - cavernous bodies of the penis and it has hollow
• corpus spongiosum is spongy and has hollow spaces
• the blood flows in corpus spongiosum
• penile rection wis hardening of penis
• helicine artery is the main supplier of blood in cavernosa and spongiosum corpus
• penis that is not erecting is flaccid
• the most immature sperm is spermatogonia
• once the sperm is in mature state, the chromosome is now in haploid cell
• haploi cell have 23 chromosomes
• spermatogonia and primary spermatocyte have 46 chromose
• myotic division is between rimary to secondary
• secondary spermatocyte, spermatid to sperm cell have 23 chromosomes
• sperm production is controlled by the hypothalamus and pituitary gland
• LH stimulates Leydig cells to secrete testosterone
• hypothalamus will release gonadotropin releasing hormone
• gonadotropin will stimulate by pituitary gland to release FSH and LH
