Acrosome
an organelle that develops over the anterior half of the head in the spermatozoa
Aspermia
lack or absence of sperm
Autosome
a chromosome that is not an allosome (a sex chromosome)
Biflagellate
having 2 flagellum
Bulbourethral gland
also called a cowper’s gland. serves to lubricate the male urethra to prepare it for ejaculation
Capacitation
the final step in the maturation of spermatozoa and is required to render them competent to fertilize and oocyte
Chromosome
DNA threadlike structures of organisms containing genes (alleles); “colorful body”
Diploid
having two haploid sets of homologous chromosomes
Ductus Deferens
part of the male reproductive system; these tube transport sperm from the epididymis to the ejaculatory ducts in anticipation of ejaculation. AKA: Vas Deferens
Ejaculation
emission of semen from the penis
Epididymis
a tube that connects a testicle to a vas deferens in the male reproductive system. spermatids mature here by acquiring their flagellum. “on the twins”
Gamete
male or female reproductive cell having the haploid number of chromosomes
Genitalia
male and female reproductive structures
Genitourinary
of or relating to the genital and urinary organs and their functions
Genotype
the actual composition of the alleles (genes)
Groin
depression marking the juncture of the lower abdomen and the inner part of the thigh
Haploid
having the gametic number (half) of chromosomes typically including one of each pair of homologous chromosomes
Heterozygous
having two different alleles of a particular gene or genes
Homozygous
having two identical alleles of a particular gene or genes
Inguinal
of, relating to, or situated in the region of the groin or in either of the lowest lateral regions of the abdomen
Membranous Urethra
intermediate part of male urethra
Oscheitis
inflammation fo the scrotum
Orchitis
inflammation of the testes
Perineum
the space between the anus and scrotum in the male and between the anus and the vulva in the female
Phenotype
the observable expression of genes (alleles)
Prostatic urethra
part of the male urethra from the base of the prostate gland where the urethra begins as the outlet of the bladder to the point where it emerges from the apex of the prostate gland
Scrotal
pertaining to the testicular sac
Seminal
pertaining to semen
Seminal Vesicle
a pair of simple tubular glands posteroinferior to the urinary bladder of some male mammals
Seminiferous
tubules the are located within the testes, and are the specific location of meiosis, and the subsequent creation of male gametes
Spermatogenesis
the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis
Spongy Urethra
the penile portion of the urethra
Testosterone
hormone produced by testes and is responsible for inducing and maintaining male secondary sex characteristic
Vas Deferens
the duct from the epididymis to the seminal vesicle
