Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

14.9K
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...

Nociception01:44

Nociception

35.0K
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.

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...

Spinal Cord: Cross-sectional Anatomy01:16

Spinal Cord: Cross-sectional Anatomy

6.5K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.
Gray Matter and its Components
Central to the gray matter is...

Dense Connective Tissue01:13

Dense Connective Tissue

14.2K
Dense connective tissue contains more collagen fibers than loose connective tissue. As a consequence, it displays greater resistance to stretching. There are two major categories of dense connective tissue— regular and irregular.
Dense Regular Connective Tissue
In dense regular connective tissue, fibers are arranged parallel to each other, enhancing its tensile strength and resistance to stretching in the direction of the fiber orientations. Ligaments and tendons are made of dense regular...

Sympathetic Pathways: Sympathetic Chain Ganglia01:20

Sympathetic Pathways: Sympathetic Chain Ganglia

7.9K
The sympathetic chain ganglia, also known as the sympathetic trunk ganglia or paravertebral ganglia, are a series of ganglia located bilaterally on either side of the spinal column. These ganglia serve as relay stations for the sympathetic nervous system. Preganglionic neurons originating in the spinal cord project their axons to the sympathetic chain ganglia. Within the ganglia, these preganglionic fibers synapse with postganglionic neurons.The postganglionic neurons of the sympathetic trunk...

  • Cognitive Science

Background:

  • Traditional pain research relied on explicit cognitive manipulations.
  • Emerging evidence shows spontaneous, dynamic brain network communication and fluctuating attention.
  • Pain perception is influenced by intrinsic attention and neural dynamics.

Purpose of the Study:

  • Introduce the concept of a dynamic 'pain connectome'.
  • Explore the role of spontaneous attentional fluctuations in pain.
  • Facilitate personalized pain therapies by understanding individual differences in pain attention and neural dynamics.

  • Review of recent progress in understanding neural mechanisms of spontaneous attention and pain variability.
  • Analysis of individual differences in intrinsic attention to pain.
  • Examination of neural network dynamics in chronic pain.

Main Results:

  • Spontaneous brain-wide network communication is intrinsically dynamic.
  • Attentional states fluctuate constantly, influencing pain perception.
  • Individual differences in attention and network dynamics are crucial for pain variability.

Conclusions:

  • The concept of a dynamic pain connectome offers a new framework for understanding pain.
  • Personalized pain therapies can be developed by considering individual attention-pain interactions.
  • The dynamics of pain-attention interactions are essential for identifying neural signatures of pain.
