Lab Act 7 Flashcards
Also known as Areolar Tissue
Loose Fibrous Connective Tissue
is widely distributed throughout the body and has very typical characteristics
Adipose Tissue
This tissue is often lacy in appearance and is found in numerous fluid- filled spaces.
Loose Fibrous Connective Tissue
It constitutes the loose packing material in many organs.
Loose Fibrous Connective Tissue
connects the skin to underlying structures
Loose Fibrous Connective Tissue
Loose Fibrous Connective Tissue is composed of?
collagen fibers, elastic fibers, fibroblasts and mast cells
Loose Fibrous Connective Tissue can be found where?
directly under all epithelial tissue
It has very little extracellular matrix
Adipose Tissue
This tissue is characterized by large, round, open spaces separated by very thin plasma membranes
Adipose Tissue
They contain a large lipid droplet inside that is dissolved away during preparation of the slides making them appear clear and open.
Adipose Tissue
This pushes the nucleus and other organelles of the cell up against the plasma membrane in Adipose tissues
lipid droplet
This tissue is one of the easier tissues to identify in that it looks much like a hair net
Adipose Tissue
Where are adipose tissues mostly found in?
subcutaneous areas
Adipose tissues can be found in?
(Clue: M, Rp, Mg, K, C)
mesenteries, renal pelvis, mammary glands, around the kidneys and attached to the surface of the colon.
This tissue is composed primarily of very large collagen fibers that are tightly packed in parallel bundles
Dense regularly arranged fibrous connective tissue
They are scattered among the parallel collagen fibers are the elongate, sliver-like nuclei of the fibroblasts that run parallel to the direction of the fibers.
Dense regularly arranged fibrous connective tissue
This tissue has a very poor blood supply; consequently, when it is damaged, it takes a long time to heal
Dense regularly arranged fibrous connective tissue
Is found in tendons and ligaments
Dense regularly arranged fibrous connective tissue
Like regularly arranged connective tissue, this connective tissue is also composed of large collagen fibers
Dense irregularly arranged fibrous connective tissue
In this tissue, however, the fibers are not all parallel, but run in several different directions
Dense irregularly arranged fibrous connective tissue
nuclei of the fibroblasts in this CT are more oval shaped
Dense irregularly arranged fibrous connective tissue
Dense irregularly arranged fibrous connective tissue is found in?
(Clue: D,Ocbt, Fcoj)
dermis of the skin, the outer coverings of body tubes, and the fibrous capsules of organs and joints
This refers to the small cavity in the substance of the bone containing an osteocyte.
Lacunae
They are the principal active cells of connective tissue that appear large, flat, elongated (spindle-shaped) cells possessing processes extending out from the ends of the cell body.
fibroblasts
It is a thin layer of connective tissue that covers the outer surface of a bone in all places except at joints.
Periosteum
The fibers in the matrix have a loose and irregular arrangement, and they consist of collagenous, elastic, or reticular fibers.
Areolar
They are also known as perforating holes or channels, are anatomic arrangements in cortical bones.
Volkmann’s canal
They are found close to small blood vessels in loose connective tissue. They contain large secretory granules of heparin proteoglycan - a weak anticoagulant. They also contain histamine, which promotes an inflammatory reaction when secreted.
Mast cells
It is a layer of dense irregular connective tissue that surrounds the cartilage of developing bone.
Perichondrium
They are bundles of proteins found in extracellular matrix of connective tissue and produced by fibroblasts and smooth muscle.
Elastic fibers
also known as resident cells
Fixed cells
They are stable, long-lived cells, such as fibroblasts and fat cells, that have grown and remain within connective tissue where they carry out their duties
Fixed cells
are leukocytes that circulate in the bloodstream and migrate into connective tissue at signs of an immune response
transient cells
Examples of fixed cells
(F, A, M)
Fibroblast, Adipocytes, and Macrophages
Examples of Transient Cells
(N, E, B)
Neutrophils, Eosinophils, and Basophils
