CONNECTIVE TISSUES Flashcards
○ has the capacity to stretch and recoil
○ rubber-like protein
★ elastin
○ forming mesh-like structures such as in the spleen
○ shape the tissue
★ reticular fibers
○ strongest and the thickest among the three fibers
★ collagen fibers
CONNECTIVE TISSUE FUNCTIONS
- Structure and Support
- Binding and Connecting
- Transportation
- Immune Response
- Cushioning and Shock Absorption
- Repair and Healing
★ bone to bone
ligaments
★ bone to muscles
tendons
★ muscles to muscles
fascia
prevent the collision of joints and bones;
absorb shock
cartilage
○ excess skin
keloid
★ viscous
★ has collagen and elastic protein fibers
★ highly vascularized
★ contains different cells
AREOLAR
○ produce fibers for extracellular matrix
○ contains collagen fibers - strength and structure
○ elastin fibers
★ fibroblast cell
★ globlets
★ highly vascularized
★ made of adipocytes
ADIPOSE
○ fat cells
○ in the form of triglycerides (our body)
○ stores energy
○ contains oils that insulate the body parts and serve
as an energy reservoir
adipocytes
★ helps with vascularity
★ deliver nutrients, hormone, oxygen to adipose tissue
ADIPOSE
★ for energy storage
white adipose tissue
★ ○ produces heat thermogenesis
brown adipose tissue
★ branching networks
★ scaffold organs
○ bones, lymph nodes, spleen
★ produces fibers
★ framework
★ sakura-like
RETICULAR
★ parallel pattern of collagen
★ collagen fibers
★ tightly packed collagen fibers
★ avascularized
★ tendons and ligaments
REGULAR
★ collagen fibers - for strength
★ skin, dermis, coverings of bones (periosteum)
IRREGULAR
★ no collagen fiber
★ has elastic fibers
★ has fibroblasts - maintain elastic fibers
★ can be seen on the trachea, vocal chords, walls of some
arteries
ELASTIC
★ simply as cartilage
★ avascularized
○ when injured, it may never recover or take a long
time
HYALINE
★ glassy, translucent appearance
★ has gel-like matrix
★ maintain the support of various structures
★ trachea, bronchi, nose, skeleton of fetus, larynx, and
joints
HYALINE
★ has characteristics of a dense CT and cartilage
★ contains collagen
★ intervertebral disc
FIBROCARTILAGE
○ middle of the spine
○ cushion and shock absorber
★ intervertebral disc
○ shock absorber of knee
★ meniscus of the knee
★ high content of elastic fibers
○ flexible, elastic compared to other cartilage
★ high degree of cartilage
★ collagen fibers
★ external of the ear
★ epiglottis
ELASTIC CARTILAGE
★ more solid, less flexible
★ vascularize
BONE
★ dense, hard bone
★ seen on the outer layer of the bones
COMPACT
COMPACT is formed from a mineralized collagen fiber
hydroxyapatite
○ made of calcium phosphate
○ gives hardness to bones
hydroxyapatite
★ cell of bones
osteocytes
★
○ ring-like structure
○ where haversian canal is formed
osteon / haversian system
★
○ nerves and blood vessels
○ center
central canal / haversian canal
★ sponge, porous-look
★ latis look
★ interior layer of the bone
★ good blood supply
★ plays a role on hematopoiesis
★ absorbs shocks
SPONGY
○ produces RBC
○ sa butas-butas
★ bone marrow
hematopoiesis
○ formation of our blood
○ blood - circulate oxygen, carbon dioxide all
throughout our body
★ 55% plasma
★ transport nutrients, fight pathogens
BLOOD
○ rare type of disease
○ usually happens when a blood clot in the deep veins
in your leg breaks o and travels to your
lungs/heart?
○ happens more often with women - taking pills
○ the blood thickens which causes blood clot
○ inject steroid for like a week, expensive
★ pulmonary embolism
★ transportation of nutrients and gasses throughout the
body
RED BLOOD CELLS / ERYTHROCYTES
★ protects our body from foreign invaders
WHITE BLOOD CELLS / LEUKOCYTES
★ blood clotting
PLATELETS
★ clear color
★ where WBC flows
★ transports lymphocytes - fights pathogenic bodies
★ bukol - nilalabanan ng lymph nodes ang infection,
namamaga ang lymph nodes
LYMPH
fights pathogenic bodies
lymphocytes
