The Parathyroid Glands00:59

The Parathyroid Glands

5.8K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

Hormones and Bone Tissue01:17

Hormones and Bone Tissue

4.2K
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...

Pulse01:16

Pulse

2.7K
When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level.
The pulse serves as a clinical...

Pulse01:05

Pulse

4.6K
The pulse is one of the most fundamental physiological indicators of the body's cardiovascular health. It is the rhythmic expansion and contraction of the arterial walls in response to the pressure generated by the heart's pumping action.
Pulse Rate and its Significance
Pulse rate, often measured in beats per minute (bpm), reflects the heart rate (HR), which is influenced by numerous factors such as stress, physical activity, and hormonal changes. A normal resting adult pulse rate falls...

Measurement of Blood Pressure01:17

Measurement of Blood Pressure

4.0K
Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

6.7K
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...

Area of Science:

  • Endocrinology
  • Bone Biology
  • Metabolic Bone Disease

Background:

  • Parathyroid hormone (PTH) secretion exhibits an ultradian rhythm, comprising tonic and pulsatile components.
  • Healthy individuals display predominantly tonic PTH secretion, with ~30% released in high-frequency bursts every 10-20 minutes.
  • Alterations in ultradian PTH secretion patterns are observed in osteoporosis patients.

Purpose of the Study:

  • To review literature data on ultradian PTH secretion changes in primary and secondary osteoporosis.
  • To explore the hypothesis correlating modified ultradian PTH secretion with skeletal fragility.
  • To investigate the potential of ultradian PTH secretion as a diagnostic and therapeutic indicator, especially in secondary osteoporosis.

Main Methods:

  • Literature review of studies investigating PTH secretion patterns.
  • Analysis of data correlating ultradian PTH secretion components (pulsatile and tonic) with skeletal effects.
  • Examination of clinical parameters in primary and secondary osteoporosis.

Main Results:

  • Changes in ultradian PTH secretion dynamics are evident in primary and secondary osteoporosis.
  • Skeletal effects are influenced by reciprocal modifications of pulsatile and tonic PTH secretion components.
  • Conventional diagnostic parameters may not always be reliable for secondary osteoporosis.

Conclusions:

  • Altered ultradian PTH secretion patterns are associated with skeletal fragility in osteoporosis.
  • Understanding spontaneous PTH secretion pathophysiology is crucial for managing osteoporosis, particularly secondary forms.
  • Ultradian PTH secretion warrants further investigation as a biomarker for skeletal fragility.
