Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

13.5K
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...

Bone Disorders01:29

Bone Disorders

5.0K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Pain01:20

Pain

1.2K
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...

Bone Markings01:26

Bone Markings

7.9K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

The Bone Matrix01:18

The Bone Matrix

5.4K
Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in...

Bone Structure01:55

Bone Structure

51.5K
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

Area of Science:

  • Neuroscience
  • Orthopedics
  • Regenerative Medicine

Background:

  • Fracture healing is a complex biological process.
  • The role of sensory nerves in bone repair is not fully understood.

Purpose of the Study:

  • To investigate the role of sensory nerves in promoting fracture healing.
  • To identify specific factors secreted by sensory nerves that influence bone repair.

Main Methods:

  • Utilized animal models of bone fracture.
  • Analyzed gene and protein expression in sensory nerves and surrounding tissues.
  • Assessed fracture healing progression through imaging and histological analysis.

Main Results:

  • Sensory nerves were found to be crucial for effective fracture healing.
  • Growth factors secreted by these nerves were identified as key mediators.
  • Inhibition of sensory nerve activity impaired bone repair.

Conclusions:

  • Growth factors from sensory nerves are essential for fracture healing.
  • Targeting sensory nerve pathways could represent a novel therapeutic approach for bone injuries.
  • Further research into these neuro-osseous interactions is warranted.
