Sarcomas
|
Cancer originates in bone, muscle, or other connective tissue.
|
|
|
Leukemias
|
Cancers of the blood.
|
|
|
Lymphomas
|
Cancers of the lymphoid tissues.
|
|
|
Carcinomas
|
Cancers of the epithelial (surface) tissues. Common because of skin's rapid mitosis.
|
|
|
Mitosis
|
Cell division

|
Connective Tissue's 3 characteristics
|
Specialized cells
Ground Substance, matrix Protein fibers |
|
|
Matrix
|
Ground substance, background material.
|
|
|
Fibrous connective tissue characteristics
|
Jelly-like matrix, collagen and elastin fibers. Fibroblasts in matrix produce matrix and protein fibers.
|
|
|
Connective Tissue Types
|
Fibrous
Supportive Fluid |
|
|
Fibrous connective tissue types
|
Loose Fibers (Areolar)
Dense Fibrous Adipose tissue |
|
|
Loose fibers
|
Protective covering over organs, widespread; contain elastin, collagen, and fibroblasts.
|
|
|
Dense fibrous connective tissue
|
Tendons, attach muscle to bone; Ligaments, attach bone to bone; contain collagen and fibroblasts.
|
|
|
Adipose tissue
|
Contains cells that store lipids for energy, insulation, and protection.
|
|
|
Supportive Connective Tissue Characteristics
|
Solid matrix, contain lacunae.
|
|
|
Supportive Connective Tissue Types (5)
|
Cartilage:
Hyaline Elastic Fibro Bone: Compact Spongy |
|
|
Lacunae
|
Chambers in supportive connective tissue.
|
|
|
Chondrocytes
|
Cartilage cells.
|
|
|
Hyaline Cartilage
|
Most widespread; many fine collagen fibers; found in nose, ribs, ends of long bones.
|
|
|
Elastic Cartilage
|
Many elastic fibers; flexible; found in outer ear.
|
|
|
Fibrocartilage
|
Matrix of stout collagen fibers; withstands pressure; found in knee joints, disks between vertebrae.
|
|
|
Bone
|
Matrix of calcium and other salts, giving rigidity; protein fibers give elasticity and strength.
|
|
|
Osteocytes
|
Bone cells
|
|
|
Canaliculi
|
Canals connecting osteocytes.
|
|
|
Compact Bone
|
Osteons tightly packed, found in the shaft of long bones.
|
|
|
Spongy bone
|
Spongy, but braced with bone, making it light but strong. Often encased in compact bone. Found in ends of long bones.
|
|
|
Fluid Connective Tissues (4)
|
Erythrocytes
Leukocytes Platelets Lymph |
|
|
Erythrocytes
|
Blood cells. Bi-concave, allowing them to fold and squeeze. Contains hemoglobin.
|
|
|
Hemoglobin
|
Red pigment, contains heme and the protein globin.
|
|
|
Heme
|
Iron-containing complex in blood. Iron attracts oxygen, enabling blood cell to transport oxygen.
|
|
|
Leukocytes
|
White blood cells; have nucleus; fight infection by phagocytosis; eat living cells; produce proteins called antibodies.
|
|
|
Platelets
|
Thrombocytes. Fragments of cells, form clots.
|
|
|
Lymph
|
Fluid flowing in lymphatic vessels and nodes.
|
|
|
Lymphatic Node
|
Made of fibrous connective tissue, contains leukocytes that destroy infectious microbes in lymph.
