BIOD 151 lab 3 key terms (Portage)
fibrous connective tissue
A dense tissue with large numbers of collagenous fibers organized into parallel bundles.
This is the dominant tissue in tendons and ligaments.
bone
Dense, hard connective tissue composing the skeleton. All bones are classified
according to their shape.
Cartilage
cells are called chondrocytes that secrete the gel-like ground substance around
themselves. contains no blood vessels; instead the blood vessels lay around it and drop
off nutrients, which then diffuse through the cartilage
blood
Connective tissue made of plasma, erythrocytes, leukocytes, and platelets. made up of
cells and extracellular matrix
Matrix
plasma . fibers special proteins such as antibodies and clotting proteins
Ectoderm
outermost germ layer; produces sense organs, nerves, and outer layer of skin
Mesoderm
middle germ layer; develops into muscles, and much of the circulatory, reproductive,
and excretory systems
Endoderm
innermost germ layer; develops into the linings of the digestive tract and much of the
respiratory system
Mesenchyme
The jellylike substance that separates the epidermis from the inner cells in a sponge
Hemocytoblasts
a stem cell for blood-cellular elements; especially : one considered competent to
produce all types of blood cell—called also lymphoidocyte.
Fibroblasts
biological cell that synthesizes the extracellular matrix and collagen, produces the
structural framework (stroma) for animal tissues, and plays a critical role in wound
healing. they are the most common cells of connective tissues in animals.
Chondroblasts
cartilage-forming cells that produce the matrix
Osteoblasts
bone forming cells
Osteocytes
a bone cell, formed when an osteoblast becomes embedded in the matrix it has
secreted.
Macrophages
Found within the lymph nodes, they are phagocytes that destroy bacteria, cancer cells,
and other foreign matter in the lymphatic stream.
