Endocrine Glands

@@Home -> BiologicalLifeResearch -> BrainAreaTEA -> BrainRegionTARGET_TEA_ENDOCRINE

This page covers biological details of component Endocrine Glands. Region is part of aHuman target integrated biological model.

• Top-down path to region: Target -> Human Effectors (aHumanEffectors) -> Endocrine Glands (TARGET.TEA.ENDOCRINE) (see Mind Maps)
• Type: effector
• Brain area: Effector Area
• Role: targeteffector
• Function: Secrete hormones directly into the circulatory system to be carried toward a distant target organ

Components

(generated)

Component items:

• Endocrine head (endocrine-head)
  • Endocrine - pituitary gland: release hormones by request from HT
    • Adenohypophysis (LAC.FD.HT.AR -> endocrine-adenohypophysis): secrete releasing hormones into blood
      • Distal Part of Hypophysis
      • Intermediate Part of Hypophysis
      • Tuberal Part of Hypophysis
    • Neurohypophysis (LAC.FD.HT.SO -> endocrine-neurohypophysis-vasopressin): transport vasopressin secreted in hypothalamus to blood
      • Infundibular Stem
      • Pars Nervosa of Hypophysis
    • Nucleus of Medial Eminence (LAC.FD.HT.PV -> endocrine-neurohypophysis-oxytocin): transport oxytocin secreted in hypothalamus to blood
      • Anterior Median Eminence
      • Posterior Median Eminence
    • Lateral Eminence of Hypophysis
  • Endocrine - pineal gland (endocrine-pineal-gland): control of sexual development
• Endocrine neck (endocrine-neck)
  • Endocrine - thyroid gland (LAC.PN.SYM.MCG -> endocrine-thyroid-gland): release thyroid hormones into blood to rise oxygen use and heat production
  • Endocrine - parathyroid gland (LAC.PN.SYM.MCG -> endocrine-parathyroid-gland): release parathyroid hormones into blood to increase in blood calcium levels
• Endocrine body (endocrine-body)
  • Endocrine - pancreas (endocrine-pancreas): release digestive enzymes that act in small intestine to increase rate of glucose uptake and metabolism by most body cells
    • Endocrine - pancreas, sympathetic (LAC.PN.SYM.CEG -> endocrine-pancreas-adrenergic): sympathetic, a2: decreases secretion from beta cells, increases secretion from alpha cells, b2: increases secretion from beta cells
    • Endocrine - pancreas, parasympathetic (LAC.PN.PSYM.GUT -> endocrine-pancreas-muscarinic): parasympathetic, stimulates insulin secretion, M3: increases stimulation of alpha cells and beta cells
  • Endocrine - adrenal gland (LAC.PN.SYM.SMG -> endocrine-adrenal-gland): releasing hormones in response to stress
• Endocrine - gonads (endocrine-gonads): release estrogen, progesterone and testosterone hormones to promote maturation of reproductive organs
  • Endocrine - testicle gland (LAC.PN.SYM.ARG -> endocrine-testicle-gland): produce androgens, primarily testosterone (growth of muscle mass and strength, regulator of cognitive and physical energy, sperm development
  • Endocrine - ovary gland (LAC.PN.SYM.ARG -> endocrine-ovary-gland): secretes estrogen (maturation and maintenance of the reproductive organs), testosterone (prepares the uterus for pregnancy, and the mammary glands for lactation) and progesterone (promoting menstrual cycle changes in the endometrium
