Pteroylpolyglutamic Acids
|
D011624 |
[Derivatives of folic acid (pteroylglutamic acid). In gamma-glutamyl linkage they are found in many tissues. They are converted to folic acid by the action of pteroylpolyglutamate hydrolase or synthesized from folic acid by the action of folate polyglutamate synthetase. Synthetic pteroylpolyglutamic acids, which are in alpha-glutamyl linkage, are active in bacterial growth assays.

Pterygoid Muscles
|
D011626 |
[Two of the masticatory muscles: the internal, or medial, pterygoid muscle and external, or lateral, pterygoid muscle. Action of the former is closing the jaws and that of the latter is opening the jaws, protruding the mandible, and moving the mandible from side to side.

Puberty
|
D011627 |
[A period in the human life in which the development of the hypothalamic-pituitary-gonadal system takes place and reaches full maturity. The onset of synchronized endocrine events in puberty lead to the capacity for reproduction (FERTILITY), development of secondary SEX CHARACTERISTICS, and other changes seen in ADOLESCENT DEVELOPMENT.

Puberty, Delayed
|
D011628 |
[The lack of development of SEXUAL MATURATION in boys and girls at a chronological age that is 2.5 standard deviations above the mean age at onset of PUBERTY in a population. Delayed puberty can be classified by defects in the hypothalamic LHRH pulse generator, the PITUITARY GLAND, or the GONADS. These patients will undergo spontaneous but delayed puberty whereas patients with SEXUAL INFANTILISM will not.

Puberty, Precocious
|
D011629 |
[An autosomal dominant hereditary disorder that is characterized by gonadotropin-dependent precocious puberty due to early activation of the hypothalamic-pituitary-gonadal axis. A mutation in the KISS1R gene has been identified. OMIM: 176400
, Familial precocious puberty in boys usually presents by age 4 with rapid VIRILIZATION and is also characterized by gonadotropin-independent testosterone secretion, low secretion of LUTEINIZING HORMONE, and advanced SPERMATOGENESIS in the testis. Mutations in the LHCGR gene have been identified. OMIM: 176410
, Development of SEXUAL MATURATION in boys and girls at a chronological age that is 2.5 standard deviations below the mean age at onset of PUBERTY in the population. This early maturation of the hypothalamic-pituitary-gonadal axis results in sexual precocity, elevated serum levels of GONADOTROPINS and GONADAL STEROID HORMONES such as ESTRADIOL and TESTOSTERONE.
