Fluid Connective Tissues
Spongy Bone
Cancellous bone lacks osteons and is comprised of an irregular lattice of thin columns of bone called trabeculae.
Concentric lamellae
Concentric rings
Osteon
Haversian system, which is a cylindrical structuren resembling a sectioned tree trunk.
Elastic cartilage
Identical to hyaline cartilage except that it contains an abundant network of fine elastic fibers in addition to collagen fibers. Located in hte auricle of the external ear, larynx, and epiglottis.
Osteocytes
Mature Cells.
platelets
Small cell fragments that lack nuclei and are frequently clumped together. Perform a hemostatic function to stop bleeding when there is a trauma to blood vessels.
Compact Bone
The densest and most prevalent form of bone tissue.
Perichondrium
The membrane surrounding cartilage
Hyaline Cartilage
The most abundant type of cartilage in the body, a conduit for nutrients and waste products.
Plasma
The transport medium for the formed elements as well as for nutrients and metabolic by products that must be removed from the blood.
Fibrocartilage
This cartilage is not enveloped by perichondrium. It is found in the pubic symphisis, outer portion of intervertebral discs and discs of knee joints.
Location of Hyaline Cartilage
Tracheal and bronchi
Cartilage
a specialized form of connective tissue with a firm consistency of extracellular matrix that allows thte tissue to bvear mechanical stress without permanent distortion.
lacunae
fluid cavities
Hematopoisesis
production of red blood cells (occurs in spongy bone, where bones are not heavily stressed or stress occurs from many directions).
erythrocytes
red blood cells; appear as pink biconcave discs that are filled with hemoglobin and lack nuclei.
leukocytes
white blood cells have dense purple nuclei of varying shapes.
