Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

15.4K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Pain01:20

Pain

2.1K
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

4.5K
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Nociception01:44

Nociception

28.4K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

Angina III: Clinical Manifestations and Assessment01:29

Angina III: Clinical Manifestations and Assessment

484
Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...

Herniated Intervertebral Disc l: Introduction01:29

Herniated Intervertebral Disc l: Introduction

44
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Summary
This summary is machine-generated.

The eyes may lead the body, but prolonged near work overloads the visual system, potentially causing musculoskeletal issues. Further research into eye-neck/shoulder interactions is needed for workplace ergonomics.

Area of Science:

  • Ophthalmology
  • Ergonomics
  • Physiotherapy

Background:

  • The traditional view suggests the eyes guide body posture, but evidence is limited.
  • The visual system, specifically accommodation and vergence, shows signs of overload from modern work, including eye strain and myopia.
  • The long-term musculoskeletal effects of sustained visual demand remain understudied.

Purpose of the Study:

  • To investigate the interaction between visual demands and musculoskeletal health, particularly in the neck and shoulders.
  • To establish a research agenda for multi-scientific evidence on eye-body interactions.
  • To inform public health strategies and workplace design.

Main Methods:

  • Review of existing evidence on accommodation/vergence system overload.
  • Identification of potential research gaps concerning long-term musculoskeletal consequences.
  • Proposal for a multi-disciplinary research approach.

Main Results:

  • The accommodation/vergence system is susceptible to overload from near work, leading to symptoms like eye discomfort and transient myopia.
  • Current evidence supporting the eyes' role in leading body posture adjustment is moderate to low.
  • There is a lack of detailed study on the long-term musculoskeletal impact of high visual demands.

Conclusions:

  • A comprehensive research agenda is warranted to explore eye-neck/shoulder interactions and their public health implications.
  • Understanding these mechanisms can guide ergonomists, physiotherapists, and opticians in treating related disorders.
  • Integrating visual and musculoskeletal considerations in workplace design can improve worker well-being and productivity.
