Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

11.5K
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 Markings01:26

Bone Markings

5.6K
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...

Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis and Regeneration of Nervous Tissue

945
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Fractures: Bone Repair01:27

Fractures: Bone Repair

3.5K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Summary

The peripheral nervous system (PNS) plays a key role in bone regeneration. Nerves regulate bone repair by communicating with bone cells, blood vessels, and immune cells.

Area of Science:

  • Biomedical Science
  • Regenerative Medicine
  • Neuroscience

Background:

  • Skeletal tissue possesses a complex innervation, with recent discoveries identifying diverse nerve types within bone.
  • The precise mechanisms of communication between bone and nerves, known as crosstalk, are not fully understood.

Purpose of the Study:

  • To review the role of the peripheral nervous system (PNS) in bone regeneration after injury.
  • To explore the distribution and function of PNS in skeletal tissue during physiological states, fracture healing, and regeneration.

Main Methods:

  • Literature review synthesizing current research on nerve distribution in bone.
  • Analysis of the communication pathways between the PNS and the bone microenvironment.
  • Examination of the role of neuropeptides, neurotransmitters, and peripheral nerve cells in bone repair.

Main Results:

  • Nerves are conserved in tissue regeneration across species, from amphibians to mammals.
  • The PNS is distributed throughout the skeletal system, changing in presence during injury and healing.
  • The PNS interacts with bone cells, vasculature, and immune cells within the bone microenvironment.

Conclusions:

  • The peripheral nervous system significantly regulates bone regeneration.
  • Communication occurs via neuropeptides, neurotransmitters, and cells within peripheral nerves.
  • Understanding bone-nerve crosstalk is crucial for developing novel bone repair strategies.
