R0138300 (rĭ-lăk′sĭn)n. A female hormone secreted by the corpus luteum that helps soften the cervix and relax the pelvic ligaments in childbirth.

relaxin

(rɪˈlæksɪn) n1. (Biochemistry) a mammalian polypeptide hormone secreted by the corpus luteum during pregnancy, which relaxes the pelvic ligaments2. (Pharmacology) a preparation of this hormone, used to facilitate childbirth[C20: from relax + -in]

re•lax•in

(rɪˈlæk sɪn)

n. a polypeptide hormone, produced by the corpus luteum during pregnancy, that causes the pelvic ligaments and cervix to relax during pregnancy and delivery. [1925–30]

Thesaurus

Noun

relaxin - hormone secreted by the corpus luteum during the last days of pregnancy; relaxes the pelvic ligaments and prepares the uterus for laborendocrine, hormone, internal secretion - the secretion of an endocrine gland that is transmitted by the blood to the tissue on which it has a specific effect

Relaxin

relaxin

[ri′lak·sən] (biochemistry) A hormone found in the serum of humans and certain other animals during pregnancy; probably acting with progesterone and estrogen, it causes relaxation of pelvic ligaments in the guinea pig.

Relaxin

a hormone formed mainly in the ovaries that produces relaxation of the ligaments of the pubic symphysis of the pubic bones during pregnancy; as a result, the pelvis widens and normal childbirth is facilitated. Relaxin also characteristically inhibits the spontaneous contractions of the uterus.

Chemically relaxin is a polypeptide. Refined sow relaxin exhibits pronounced basic properties; it has molecular weight of about 6,500 and a structure of two subunits, consisting respectively of 22 and 28–31 amino-acid residues, joined by a disulfide bond. The primary structure has not been determined. The biosynthesis of either relaxin or the polypeptides that are closely related to it structurally is also possible in tissues found in the uterus and placenta.

relaxin

re·lax·in

(rē-lak'sin), A polypeptide hormone secreted by the corpora lutea of mammalian species during pregnancy. Facilitates the birth process by causing a softening and lengthening of the pubic symphysis and cervix; it also inhibits contraction of the uterus and may play a role in timing of parturition. Synonym(s): cervilaxin, ovarian hormone, parturition-mediating factor, releasin [relax + -in]

re·lax·in

(rĕ-lak'sin) Polypeptide hormone secreted by the corpora lutea of mammalian species during pregnancy; facilitates birth process by softening and lengthening the pubic symphysis and cervix.

relaxin

A polypeptide found in the corpus luteum of various mammals that softens the neck of the womb (cervix) and relaxes the pubic joint of the pelvis to ease childbirth. Relaxin has not been proved to occur in humans.
