Hormones and Bone Tissue01:17

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
Synthesis and Functions of Calcitonin00:51

Synthesis and Functions of Calcitonin

Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...
Cells and Secretions of the Pancreas01:16

Cells and Secretions of the Pancreas

The pancreas, a vital organ within the abdominal cavity, plays dual roles in the digestive and endocrine systems, collaborating with exocrine and endocrine cells to maintain optimal digestion and blood sugar levels.
Exocrine function is carried out by acinar cells, organized into clusters known as acini. These cells contribute to digestion by releasing substantial quantities of enzyme-rich, alkaline digestive juices.
Concurrently, the dispersed clusters of endocrine cells throughout the...
Glucose Homeostasis: Pancreatic Islets and Insulin Secretion01:27

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
Insulin and C-peptide are co-secreted in...

Area of Science:

  • Endocrinology
  • Gastroenterology
  • Pancreatic Physiology

Background:

  • The exocrine pancreas is crucial for digestion.
  • Thyroid hormones influence various bodily functions.
  • The role of thyroid hormones in exocrine pancreatic function is not fully understood.

Purpose of the Study:

  • To investigate the impact of hypothyroidism on exocrine pancreatic function.
  • To assess the effect of thyroxine treatment on pancreatic function in hypothyroid patients.

Main Methods:

  • Amino acid consumption test (a novel tubeless method) was used to measure pancreatic uptake of amino acids during stimulated enzyme synthesis.
  • Plasma amino acid levels were monitored.
  • Duodenal intubation was performed in two patients to measure pancreatic secretion of bicarbonate and enzymes.

Main Results:

  • Exocrine pancreatic function was significantly reduced in hypothyroid patients compared to healthy controls.
  • Thyroxine treatment restored pancreatic function to normal levels.
  • Reduced secretion of bicarbonate and enzymes was observed in hypothyroid patients.

Conclusions:

  • The thyroid gland plays a critical role in maintaining the functional integrity of the human exocrine pancreas.
  • Hypothyroidism leads to impaired exocrine pancreatic function.
  • Thyroxine replacement therapy can reverse pancreatic dysfunction in hypothyroid individuals.
