sem·i·nal gland

one of two folded, sacculated, glandular structures that is a diverticulum of the ductus deferens; its secretion is one of the components of semen; it normally does not store spermatozoa as was previously thought.

seminal vesicle

Either of a pair of pouchlike glands situated on each side of the male urinary bladder that secrete seminal fluid and nourish and promote the movement of spermatozoa through the urethra.

seminal vesicle

either of the paired saclike glandular structures posterolateral to the urinary bladder in the male and functioning as part of the reproductive system. Each sac is pyramidal in shape and convoluted in appearance and at the anterior extremity becomes constricted into a narrow straight duct that joins the vas deferens to form the ejaculatory duct. The seminal vesicles produce a fluid that is added to the secretion of the testes and other glands to form the semen.

sem·i·nal ves·i·cle

(sem'i-năl ves'i-kĕl)
One of two folded, sacculated, glandular diverticula of the ductus deferens; its secretion is one of the components of semen.
