Suffolk test 2 Flashcards
What tissue is avascular aka lacks its own blood supply
Epithelial
Single or multiple layered sheet of cells. Makes the covering and lining of the body. Protection secretion and avsorption
Epithelial tissues
The type of simple squamous that lines the heart, blood vessels, and lymphatic vessels
Endothelium
The type of epithelial layer of serous membranes such as pericardium, pluera, and peritoneum
Mesothelium
This epithelial tissue derives from the embryonic mesoderm
Endothelium
Mesothelium
Simple squamous
Allows passage of materials by diffusion and filtration. Found in the lining of hear. Air sacs in lungs. Blood vessels and lymphatic system
Simple squamous
Epithelial tissues found in thyroid gland and kidney tubules
Simple cuboidal
Epithelial tissues that line digestive tract. Gallbladder. Protects stomach lining from acids. Function is secreting mucus.
Non ciliated columnar epithelium
Goblet cells are found and for what purpose
Simple columnar
Produces mucous for lubrication
Epithelial tissues found in
Respiratory system and uterine tubes.
Ciliated simple columnar
Epithelial tissue found in respiratory system, trachea, male urethra and epididymis . Nuclei seen at different levels.
Ciliated pseudo stratified columnar
Keratinized tissue found in superficial layers of skin
Stratified squamous
Nonkeratinized tissue found in mout and esophagus . Major function is protection
Stratified squamous
This tissue is found in the lining of the vagina
Stratified squamous
Rare type of epithelial tissue
Function is protection
Only found in sweat gland ducts and urethra
Stratified cuboidal
Uncommon epithelial tissue
Multayered
Found in very large ducts and part of the male urethra
Stratified columnar
Epithelial tissue
Found only in the urinary system
Allows for expansion of urinary organs
Transitional
Connective tissue cells:
Secretes fibers and components of ground substance
Fibroblasts
Connective tissue cells:
Store triglycerides
Adipocytes
Connective tissue cells:
Produces histamine
Mast cells
Connective tissue cells:
Immune response
Neutrophil and eosinophils
White blood cells
Connective tissue cells:
Engulf bacteria and cellular debris
By phagocytosis
Macrophages
Connective tissue cells:
Secretes antibodies
Plasma cells
Between cells and fibers
Fluid like and functions to support cells, store water, and allow exchange between blood and cells
Ground substance
Name three types of connective tissue fibers
Collagen
Reticular
Elastic
Tissue fibers:
Tough, resistant to pull
25% of bodies protein
Collagen
Tissue fibers:
Formed from protein elastin and glyco protein
Lungs blood vessels ear cartilage
Elastic
Tissue fibers:
Form a framework of organs
Spleen and lymph nodes
Reticular
Classification of tissues:
Found in umbilical chord
Mucous
Loose connective tissue
Areolar
Adipose
Reticular
Tissue most widely distributed in the body
Areolar
Tissue that contains adipocytes
Insulation
Reserves food stores
Found under under skin local fat deposits. Abdomen and breasts
Adipose
Loose connective tissue found in liver, spleen , lymph nodes. Lies in a fiber network. Holds organs together
Reticular
Three types of dense connective tissue
Dense regular
Dense irregular
Elastic tissue
Tissue found in tendons and has fibroblasts. Found in ligaments
Dense regular
Tissue found in dermis of skin and heart and has fibroblasts. Irregularly shaped
Dense irregular
Tissue that can stretch found in lung tissues an arteries , vocal chords
Name three cartilage tissues
Hyaline
Fibrocartilage
Elastic cartilage
A dense network of collagen fibers and elastic fibers firmly embedded I’m chondroitin sulfate
A dense network of collagen fibers and elastic fibers firmly embedded I’m chondroitin sulfate
Cartilage
Cartilage cells found in the spaces called the lacunae
Chondrocytes
Coverage of dense irregular connective tissue that surrounds cartilage. Two layers
Pericondrium
No blood vessels or nerves except. Pericondrium.
.
Most abundant cartilage in the body
Hyaline
This cartilage acts as a cushion
Found in embryonic skeleton
Nose trachea and larynx
Hyaline
In hyaline cartilage Chondrocytes sit in spaces called
Lacunae
Hyaline cartilage repairs very slow due to
No blood vessels or nerves
Similar to hyaline cartilage but with more elastic fibers
Elastic cartilage
This cartilage maintains shape and structure while allowing flexibility
Support external ear
Nose
Vocal cartilages
Elastic cartilage
This cartilage provides tensile strength and absorbs compression shock. Found in inverterbral discs, pubic symphysis , discs of knee joint
Fibrocartilage
Cartilage grows slowly
Repairs are slow due to the fact they are
Avascular
Two patterns of cartilage growth
Interstitial growth
Appositional growth
Growth from within cartilage tissue occurs in adolescence
Interstitial growth
