specialized connective tissue Flashcards
3 Specialized connective tissues
Adipose , cartillage, bone
In between white and brown are
beige adipose
fats cells, lipid containing cells
Adipocytes
functions of adipose tissues
Insulation
Support
Cushioning
Regulation of metabolism
Energy storage
Specialized for long-term energy storage
White Adipose Tissues
possessing one cavity. Cavity consists
of fats
*Fats dissolve in most fixatives
Unilocular
signet-ring appearance
Adipocyte
Benign tumors that are mainly composed of
fats
lipomas
malignant tumors, mainly
composed of (FATS) white adipose tissue
Liposarcomas
malignant)
can be found sa newborns. Mainly composed of
brown adipose tissues.
hibernomas
Carry fats → liver → synthesizes fat
it will be synthesized to LDL
chylomicrons
Bad cholesterol → tissues → lipids
LDL
build up of fats sa
cardiac veins or arteries
Artherosclerosis
returns fat back to the liver for re-synthesis
HDL
purpose of lipoprotein lipase
Released by tissues to dissolve lipids for
tissue consumption. In order to intake the tissue it needs to dissolve(melt)
are enzymes that dissolve the fats sa tissues
pag nadeliver na ni LDL.
Lipoprotein lipase
hormones involved in lipid
metabolism?
insulin, norepinephrine, non-carbohydrate, and leptin
Causes adipocytes to uptake
glucose
insulin
initiates _____
→ transforming non-carbohydrate into
glucose. → releases more energy through
lipolysis.
Norepinephrine; Gluconeogenesis
Ketone bodies, Fats, Amino Acids.
Non-carbohydrate
Hormone released by adipocytes.
Brain controls appetite.
leptin
Several cavities containing fats
Mutilocular
Why is it brown?
organelles are present in cytoplasm in brown adipose tissue and they are scattered especially in mitochondria
white adipose tissue - natutulak ng isa lipid globule yung nucleus
Main function of brown adipocytes
Thermogenesis: Warm the blood.
Creation of heat. → iikot sa blood cells to
warm the blood
predominant cell in ECM of cartilage
Chondrocytes
Cartilage ex.
ears
Cartilage ex.
ears
Main constituent of ECM?
elastic fiber
Purpose of the perichondrium?
Layer that surrounds the cartilage
- Most common type of cartilage
- Homogeneous and semitransparent
- Located in the articular surfaces of movable joints, in
the walls of larger respiratory passages (nose,
larynx, trachea, bronchi), in the ventral ends of ribs,
where they articulate with the sternum, and in the
epiphyseal plates of long bones
Hyaline Cartilage
What happens in Osteoarthritis
They regenerate poorly
Happens when thin hyaline cartilage
What happens in osteoarthritis: happens
kapag super thin na yung hyalin cartilage.
Cartilage acts as a lubricant para di
magkiskisan yung bones. Happens kapag
nagkiskisan na sila kasi manipis na hyalin
cartilage
- Fresh specimens are yellowish in color
- Found in the auricle of the ear, the walls of the
external auditory canals, the auditory (Eustachian)
tubes, the epiglottis, and the upper respiratory tract.
Elastic Cartilage
Mingling of hyaline cartilage and dense connective
tissue
* It is found in intervertebral discs, in attachments of certain ligaments, and the pubic symphysis—all places where it serves as very tough yet cushioning support tissue for bone.
Fibrocartilage
Serves as a reservoir of calcium, phosphate and
other ions.

Osteoclasts:
Inner Portion of the bones
Endosteum
Outer layer of the bones
