Dietary Connections

61.5K
In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

Functions of Connective Tissues01:17

Functions of Connective Tissues

14.8K
Connective tissues perform a broad range of functions in the body. Their primary function is to connect and link different tissues in the body and act as packaging material between tissues. The areolar tissue, a connective tissue prototype, commonly cements various tissue types in diverse body organs. In contrast, adipose tissue cushions internal organs while insulating the body from heat loss.
Hard connective tissues, such as bones and cartilage, provide structure and support to the body.

Loose Connective Tissue01:26

Loose Connective Tissue

9.3K
Loose connective tissue is found between many organs. Its main function is to absorb shock and bind tissues together. It also allows water, salts, and various nutrients to diffuse into cells that are embedded in it or present in adjacent tissues.
Adipose Tissue
Adipose tissue consists primarily of fat storage cells called adipocytes and little extracellular matrix. A large number of capillaries present within adipose tissue allow rapid mobilization of lipid molecules. White adipose tissue is...

Introduction to Connective Tissues

13.4K
Connective tissues are one of the four main tissue types in humans that are extensively present in the body. They are characterized by cells embedded in an extracellular matrix (ECM) composed of a ground substance and three main types of protein fibers— collagen, elastic, and reticular fibers. The ground substance of connective tissues can range from a watery and jelly-like consistency to mineralized and hard. The wide variety of cells in the connective tissues include fibroblasts,...

Classification of Connective Tissues

14.7K
The connective tissues have different properties and functions in the human body. They are broadly categorized into proper, supporting, or fluid connective tissues.
Connective Tissue Proper
Connective tissue proper is the most abundant class of connective tissues. As its name implies, it predominantly connects different tissues in the body. Depending on the cell types, ground substance, viscosity, and fiber types in the ECM, connective tissue proper is further categorized into loose and dense....

Embryonic Connective Tissues01:20

Embryonic Connective Tissues

6.4K
During early development, the embryo forms two types of connective tissues— the mesenchyme and mucoid connective tissue.
The mesenchyme is the first connective tissue that emerges in the developing embryo. It consists of loosely arranged multipotent mesenchymal cells and reticular fibers in the extracellular matrix. This loose arrangement allows easy migration of cells, which is essential for germ layer positioning, patterning, and organ morphogenesis during embryonic development.

Summary
This summary is machine-generated.

Ictal coughing during seizures originates in the medial temporal lobe. This neurological symptom involves a network including perisylvian cortices and the caudate nucleus, revealed by stereo-EEG.

Area of Science:

  • Neurology
  • Neurophysiology
  • Epileptology

Background:

  • Coughing is a protective reflex involving brainstem and cortical control.
  • Ictal coughing is associated with temporal lobe epilepsy, but its precise neural basis is unclear.

Purpose of the Study:

  • To investigate the anatomo-functional correlations of ictal coughing using stereo-electroencephalography (SEEG).
  • To identify the specific brain regions involved in seizure-onset coughing.

Main Methods:

  • Intracranial seizure recordings using stereo-electroencephalography (SEEG) in a patient with ictal coughing.
  • Functional connectivity analysis (h² estimation) to map brain network involvement during coughing episodes.

Main Results:

  • Ictal coughing was observed to follow seizure onset in the medial temporal lobe.
  • Functional connectivity analysis revealed involvement of a network including perisylvian cortices and the caudate nucleus during coughing.

Conclusions:

  • The medial temporal lobe is implicated in the generation of ictal coughing.
  • Ictal coughing involves a distributed network of cortical and subcortical structures, highlighting complex brain interactions during seizures.
