________________ is a type of tissue in the body that ___________, _________, and__________ between different organs, tissues, and cells
Connective tissue is a type of tissue in the body that provides support, structure, and connection between different organs, tissues, and cells
Connective tissue can be thought of as the “_______” that holds everything together.
glue
All connective tissues are categorized and named based on its arrangement of _____________________ which the fibers are suspended in.
connective protein fibers and extracellular matrix
A type of connective tissue characterized by its loose arrangement of _______, _____, and ________ It is one of the most common types of connective tissue found throughout the body.
cells, fibers, and ground substance.
CFG
____________ is a category of connective tissue which includes areolar tissue, reticular tissue, and adipose tissue
Loose connective tissue
very common in our body
Supports ______________
Numerous _______ and ___________
epithelial celll
fibroblasts and collagen
- loose areolar connective tissue
__________is widely distributed throughout the body, underneath epithelial tissue layers, like _________ and __________.
Areolar tissue
lamina propria of the mucous membranes
___________ It is composed of a ________ ground substance, with a meshwork of collagen, elastic, and reticular fibers
semi fluid
- loose/alveolar connective tissue
_____________ is widely distributed throughout the body, underneath epithelial tissue layers, like lamina propria of the mucous membranes.
Areolar tissue
It is composed of a semi fluid ground substance, with a meshwork of collagen, elastic, and reticular fibers
Loose/areolar connective tissue
Cells found in areolar tissue are:
FPAMM
Fibroblasts
Plasma cells
Adipocytes
Mast cells
Macrophages
Named after the reticular fibers which dominate most of the composition of its structure.
reticular tissue provide a _____________ (________) to lymphoid organs (like the __________________) _________ and __________
reticular Tissue
support structure
Lymph nodes
spleen
tonsils
bone marrow
liver
The structure of adipose tissue is mainly composed of fat cells also known as ____________
adipocytes
Purpose of this tissue is for energy storage, since fat or lipids is a great method for long term energy storage
adipose tissue
Densely packed collagen fibers that are parallel to each other
Cells: fibroblasts
dense regular connective tissue
Dense regular connective tissue
Provide high tensile strength along a single axis
Offers resistance to pulling forces
Ideal for structures requiring strength and elasticity in one direction
Dense regular connective tissue LOCATION
Tendons
Ligaments
Aponeuroses
Fibers are thicker and less organized
dense IRregular connective tissue
Densely packed collagen fibers arranged in a random and irregular manner
dense Irregular connective tissue
FUNCTION of connective tissue
Provide strength, support, and resistance to tension in multiple directions
Commonly found in areas subjected to stress and strain
Acts as a protective barrier against mechanical injuries
LOCATION of irregular
DPP
Dermis of skin
Periosteum
Perichondrium
_________ also known as “___________”, is a type of embryonic tissue that serves as a precursor for various types of connective tissue in the body
embryonic connective tissue
mesenchyme
Characterized by loosely arranged cells surrounded by a _______________
gelatinous extracellular matrix.
Embryonic Connective tissue function
Structural support
Cell differentiation
Organogenesis
Tissue repair
Signaling and Morphogenesis
