Connective Tissue Part II Flashcards
Major fiber component is type III collagen
RETICULAR CONNECTIVE TISSUE
Interspersed with fibroblasts and macrophages
RETICULAR CONNECTIVE TISSUE
Located in the liver sinusoids, adipose tissue, bone marrow, lymph nodes, spleen, smooth muscle and islets of langerhans
RETICULAR CONNECTIVE TISSUE
Single lipid droplet
WHITE (UNILOCULAR) ADIPOSE TISSUE
Present in the subcutaneous layers throughout the body
WHITE (UNILOCULAR) ADIPOSE TISSUE
Common in adult human than brown adipose
WHITE (UNILOCULAR) ADIPOSE TISSUE
Multiple lipid droplet
BROWN (MULTILOCULAR) ADIPOSE TISSUE
Heavily vascularized thus brown in color
BROWN (MULTILOCULAR) ADIPOSE TISSUE
Types of Embryonic Connective Tissue
Mesenchymal connective tissue
Mucous connective tissue
Loose, amorphous connective tissue exhibiting a jelly-like matrix composed of hyaluronic acid and populated with type I and type III collagen fibers and fibroblasts
Mucous connective tissue
Located in the Wharton’s Jelly of the umbilical cord and subdermal connective tissue of the embryo
Mucous connective tissue
Present only in the embryo and consists of mesenchymal cells
Mesenchymal connective tissue
Neither vascularized nor supplied with nerves or lymphatic vessels; cells receives nutrients from surrounding connective tissue
CARTILAGE
Shock absorber
CARTILAGE
Friction-free movement of joints
CARTILAGE
Is a connective tissue sheath covering that overlies most cartilage
PERICHONDRIUM
Has outer fibrous layer and inner cellular layer
PERICHONDRIUM
Vascular, supplies nutrients to cells of cartilage
PERICHONDRIUM
Perichondrium is only present in ____ and ______
hyaline and elastic cartilages
Most abundant cartilage
HYALINE CARTILAGE
Forms the template of endochondral bone formation
HYALINE CARTILAGE
Contains type II collagen and perichondrium
HYALINE CARTILAGE
Located in the Articular ends of long bones
HYALINE CARTILAGE
Located in the Nose, larynx, trachea, bronchi, ventral ends of ribs
HYALINE CARTILAGE
Greatly resembles hyaline cartilage, except that its matrix and perichondrium possess elastic fibers
ELASTIC CARTILAGE
Somewhat yellow and more opaque than hyaline
ELASTIC CARTILAGE
_____ are more abundant and larger than hyaline
Chondrocytes
Contains type II collagen and perichondrium
ELASTIC CARTILAGE
Located in the Pinna of ear, walls of auditory canal, auditory tube, epiglottis, cuneiform cartilage of larynx
ELASTIC CARTILAGE
Does not possess a perichondrium
FIBROCARTILAGE
Includes type I collagen
FIBROCARTILAGE
Chondrocytes are often aligned in alternating parallel rows
FIBROCARTILAGE
Located in the Intervertebral disks
FIBROCARTILAGE
Located in the Articular disks
FIBROCARTILAGE
Located in the Pubic symphysis
FIBROCARTILAGE
Located in the Insertion of some tendons
FIBROCARTILAGE
Spindle-shaped, derived from mesenchymal cells
CHONDROGENIC CELLS
Can differentiate into both chondroblasts and osteoprogenitor cells
CHONDROGENIC CELLS
Derived from either mesenchymal of chondrogenic cells
CHONDROBLASTS
Are chondroblasts that are surrounded by matrix
CHONDROCYTES
As the cells of isogenous group manufactures matrix, they are pushed away from each other, forming separate lacunae and thus enlarging cartilage from within
Interstitial growth
Chondrogenic cells undergo division and differentiate into chondroblasts, which begin to elaborate matrix. In this way cartilage grows by adding to its periphery
Appositional growth
is a specialized form of connective tissue characterized by a mineralized extracellular matrix
Bone tissue
calcium phosphate in the form of hydroxyapatite crystals [Ca10(PO4)6(OH)2] (INORGANIC)
Mineral
mainly collagen (type I, VI) along with other matrix proteins (ORGANIC)
Matrix
All collagen molecules ~ _____% of total weight of bone matrix
90%
storage for elements and minerals - homeostatic regulation of blood calcium levels
Bone
mechanical structures for movement and protection of viscera
Bone
a home for hematopoietic tissue
Bone
Storage of adipose tissue: yellow marrow
Bone
Bone tissue is classified as:
Compact bone
Spongy bone
