Nerve Supply of the GI Tract01:27

Nerve Supply of the GI Tract

3.7K
The neuronal supply to the gastrointestinal (GI) tract is essential for regulating various functions, including digestion, absorption, and movement of food. This intricate network of nerves is known as the enteric nervous system (ENS), often referred to as the "second brain" of the body.
The enteric nervous system consists of two major plexuses: the myenteric plexus (Auerbach's plexus) and the submucosal plexus (Meissner's plexus). These plexuses are located within the layers of...

Blood Supply to the Digestive System01:16

Blood Supply to the Digestive System

5.4K
Splanchnic circulation refers to the network of blood vessels that supply and drain blood from the abdominal organs involved in digestion, including the stomach, liver, pancreas, intestines, and spleen. This circulation delivers essential nutrients and oxygen while removing waste products from these organs.
Blood Supply to the Digestive System: The splanchnic circulation involves three main arteries: the celiac artery (also known as the celiac trunk) and the superior and inferior mesenteric...

Energy Supply for Muscle Contraction01:25

Energy Supply for Muscle Contraction

5.7K
Skeletal muscle fibers have the unique ability to switch between rest and contraction states, using different sources of ATP for energy. The contraction cycle and Ca2+ transport back into the sarcoplasmic reticulum for relaxation require significant ATP. However, the ATP reserves in muscle fibers are limited and can only sustain contractions for a few seconds. Additional ATP production becomes necessary for prolonged contractions. As a result, muscle fibers generate ATP through various sources,...

Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

13.9K
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...

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

3.5K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Blood and Nerve Supply to the Kidney01:18

Blood and Nerve Supply to the Kidney

4.7K
The kidneys are vital organs responsible for filtering and cleaning blood, removing waste products, and regulating electrolyte levels. To perform these essential functions, they require a constant and robust blood supply.
Bloody Supply to the Kidneys:
The kidneys receive their blood supply from the renal arteries, which branch off from the abdominal aorta—the main artery supplying the abdomen and lower body. The renal arteries enter the kidneys at the hilum, a notch on the medial side of...

Area of Science:

  • Translational Medicine
  • Biobanking
  • Biomedical Research

Background:

  • Biobanks and scientists are key to translational medicine, but communication challenges hinder biospecimen utilization.
  • Biobank managers report underuse of stored biospecimens, prompting discussions on improved sample collection and availability communication.

Discussion:

  • Existing biospecimen collections may not align with current scientific research demands.
  • Scientists increasingly require serial samples with extensive clinical data, including lifestyle and environmental factors.

Key Insights:

  • A disconnect exists between the types of biospecimens stored in biobanks and the specific needs of contemporary scientific research.
  • Enhanced data associated with biospecimens is crucial for meeting the precise requirements of advanced research projects.

Outlook:

  • Explore innovative communication channels, such as dedicated journal sections, to connect biospecimen providers with researchers.
  • Facilitating targeted discovery and collection of specific biospecimens is essential for advancing translational medicine.
