Diploid (2N)

DEFINITION 4

Having the full amount of chromosomes in a particular cell of

the human species

TERM 5

Seminiferous Tubules

DEFINITION 5

tightly coiled tubules located in the testes, sight of

spermatogenesis

Where is the sight of spermatogenesis?

Seminiferous Tubules

TERM 7

Epidydymus

DEFINITION 7

The first part of the duct system where sperm finish maturing

TERM 8

Interstitial Cells

DEFINITION 8

Cells located in the connective tissue surrounding the

seminiferous tubules that produce testosterone

TERM 9

Sertoli Cells

DEFINITION 9

Special cells in the testes that provide nourishment to the

spermatids

TERM 10

Ductus Deferens

DEFINITION 10

The duct that carries sperm through the spermatic cord from

the testes to the urethra

Bulbourethral Glands

Paired glands located inferior to the prostate, secretion that

cleanses the urethra of traces of acidic urine

TERM 17

Ejaculatory Duct

DEFINITION 17

Duct formed in the prostate by the combining of the fuct

from the seminal vesicles and the ductus deferens.

TERM 18

The external genetalia of the male include

what?

DEFINITION 18

The penis and scrotum

TERM 19

Sperm

DEFINITION 19

The combination of sperm and accessory gland secretions

TERM 20

Spermatogenesis

DEFINITION 20

Production of sperm, mitosis, then meiosis I and meiosis II

DNA and Chromosomes (haploid)

TERM 22

Sperm Head

DEFINITION 22

The nucleus of the sperm

Acrosome

DEFINITION 23

Helmet-like structure similar to a large lysosome located

anterior to the sperm head

TERM 24

Midpiece

DEFINITION 24

the centrioles located here give rise to the filaments which

form the sperm tail. Mitochondria wrapped tightly around

these filaments provide the ATP needed for the whiplike

actions of the tail

TERM 25

Tail

DEFINITION 25

Flagella maid from the centrioles in the midpiece
