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.

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...

Compounds Essential to Human Function

10.0K
The human body is composed of cells that are fundamentally made up of several different molecules. These molecules are essential to carry out all physiological processes in the body and are broadly classified into organic and inorganic based on their chemical structures.
Inorganic Compounds Essential to Human Functioning
Inorganic compounds essential to human functioning include water, salts, acids, and bases. These compounds are inorganic, i.e., they do not have a carbon-hydrogen bond. Water...

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 Tissues01:11

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 Tissues01:30

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....

Summary

The superior intraparietal sulcus (IPS) sends top-down signals to modulate brain region communication during cognitive tasks. This brain pathway is crucial for adaptive behavior and efficient information processing.

Area of Science:

  • Cognitive Neuroscience
  • Neuroimaging
  • Brain Connectivity

Background:

  • Flexible interactions between brain regions are vital for goal-directed behaviors.
  • Neural mechanisms of adaptive inter-regional communication remain unclear.

Purpose of the Study:

  • Investigate sources of top-down biasing signals influencing task-evoked functional connectivity.
  • Examine how the superior intraparietal sulcus (IPS) modulates brain communication.

Main Methods:

  • Combined theta-burst transcranial magnetic stimulation (TMS) and functional magnetic resonance imaging (fMRI).
  • Subjects performed a 2-back vs. 1-back task with faces and buildings stimuli.
  • TMS was applied to the IPS and primary somatosensory cortex.

Main Results:

  • Functional connectivity between ventral temporal cortex and primary visual cortex (VC) increased with task relevance and memory load.
  • Connectivity strength correlated with correct trial performance and activity in frontal, parietal, and subcortical regions.
  • IPS-TMS, but not somatosensory cortex-TMS, reduced task-specific modulation of VC and parahippocampal place area connectivity.

Conclusions:

  • The human IPS acts as a source of top-down biasing signals.
  • These signals modulate task-evoked functional connectivity in relevant cortical networks.
  • Findings elucidate neural mechanisms of adaptive brain communication.
