Basic Anatomical Terms, Tissues Flashcards
Axial
Head (skull) Neck (Cervical region) Trunk -Thorax (Clavical - diaphragm -Abdomen (Diaphragm - pevlis) -Pelvis (Innominates & Sacrum)
Appendicular
Upper Extremity
Lower Extremity
Tissues
Group of similar cells and extracellular matrix which serve specific function.
4 Types of Tissues
Muscle
Connective
Epithelial
Nervous
Epithelial Tissue
Lines internal and external surfaces.
Protects other tissues and regulate movement into and out of other tissues.
Muscle Tissue
Types
- Smooth
- Skeletal
- Cardiac
Generates force
Striated appearance.
Nervous Tissue
Carries information.
Regulates and controls bodily functions and activity.
Connective Tissue
All connective tissue contation protien fibers.
Definition: Cells and extracellular matrix that attaches (connects), anchors, and/or protects other tissue.
Matrix (what its made of) plays a very important role.
Connective Tissue Different Protein (Matrix’s)
Collagen
Elastic
Reticular
Collagen
Made from collagen in tri-helical structure, well-organized, RESIST TENSILE LOADS (VERY LITTLE STRETCH).
Elastic
Made from elastin, has the ability to stretch, devlop tension and RETURNS TO ORIGINAL LENGTH.
Reticular
Made from collagen fibrils (small fibers), poorly organized.
4 Types of Connective Tissue
Bone
Fibrous
Cartilage
Blood
Mesenchyme
Embryological origin of all connective tissue. It is unspecialized.
-blast
Makes or builds
ex.) Fibroblast make fibrocytes
-cyte
Maintains and repairs. Cytes have extracellular matrix around them?
Fibrous Connective Tissue Types
Loose
Dense
Loose Fibrous Connective Tissue
The most abundant connective tissue in the body Mostly Collagen "Filler Tissue" Hols Vessels and nerves Poorly Organized Found in subcutaneous areas
Types of Loose Fibrous Connective Tissues
Aerolar
Adipose
Reticular
Loose Fibrous Aerolar Connective Tissue
Type of Loose Fibrous Connective Tissue
Gel-like matrix with all three fiber type; cells: fibroblasts, macrophages, mast cells and some WBC.
Function: Wraps and cushions organs. Plays and important role is inflammation.
Located: Widely distributed under epithelia of body. Forms lamina propia of mucous membrane, packages organs; surrounds capillaries.
Loose Fibrous Adipose Connective Tissue
Closely packed, fat cells.
Function: Provides reserve food fuel. Insulates, cushions, supports and protects organs.
Location: Under the skin; around kidneys and eyeballs; within abdomen; in breast.
Loose Fibrous Reticular Connective Tissue
Network of reticular fibers in a typical loose ground substance; reticular cells lie on the network.
Function: The fibers form a soft internal skeleton (Stroma) that supports other cell types including WBCs, mast cells and macrophages.
Located: Lymphoid organs (lymph nodes, bone marrow and spleen.
Dense Fibrous Connective Tissue
Primarily collagen
Various amount of organization in arrangement.
Types of Dense Fibrous Connective Tissue
Regular
Irregular
Elastic
