Connective Tissues Flashcards
originated from the embryonic mesenchyme that is differentiated into fibroblasts that develop into different types
connective tissues
functions of connective tissue
- support
- connect tissues to another (eg., muscle to bones and bones to bones)
- packing & binding materials
- storage
- transport & defense
5 major types
- bones
- cartilage
- adipose
- reticular
- gelatinous
2 general classifications of connective tissues
- loose connective tissue
- dense connective tissue
three main components of connective tissues
- cells
- fibers
- ground substance
5 overlapping types of connective tissues
- connective tissue proper
- specialized connective tissue
- embryonic connective tissue
- supporting connective tissue
- hematopoietic tissue
dense connective tissue can either be
- dense regular
- dense irregular
examples of specialized connective tissue
- bone
- cartilage
- hematopoietic blood
- adipose tissue
examples of embryonic connective tissue
- mesenchyme connective tissue
- mucous connective tissue
examples of supporting connective tissue
- bones
- cartilage
examples of hematopoietic tissue
- blood
- bone marrow
adipose tissue can be divided into
- white adipose
- brown adipose
specialized connective tissue in which cells are suspended in the intercellular fluid
hematopoietic tissue
reticular and elastic tissue are also classified as ______
specialized connective tissue
loose connective tissue is also called
areolar connective tissue
dense collagenous tissues are exemplified by
- tendons
- ligaments
- fascia
- aponeurosis
areolar connective tissue is present is the ____ and even in the _____ of the mucus membrane
- serosa in the basement membrane
- lamina propria
elastic tissues are found in the
- tunica media of main arteries
- pigment cells or chromatophores
- blood
specialized and supporting connective tissue consist of
- bone
- cartilage
connective tissue disposed into the lamellae or layered organic matrix surrounding resting bone cells in lacunae
bone
connective tissue disposed into the lamellae or layered organic matrix surrounding resting bone cells in lacunae
bone
resting bone cells
osteocytes
kind of glycoprotein that is bound to certain proteoglycans
collagen
a projecting process
calaniculi
bones of the skeletal system may be classified in 4 ways:
- region where they are found
- histological origin
- shapes
- disposition of the bone matrix
- embryonic development
histological origin varies as
- endochondral
- membranous
shapes varies as
- long
- short
- flat
- irregular
disposition of the bone matrix varies as
- spongy or cancellous
- compact bone
this bone have lamellae in concentric with a central canal
compact bone
basic unit of compact bone tissue
Haversian system or osteon
Haversian system also includes the _____
Volkman’s canal
compact bones are found in the diaphysis and periosteum of long bones like
- femur
- humerus
- tibia
- bones of digits
middle layer or the shaft of diaphysis
spongy bone
ends of a long bone
epiphyses
spongy bone is also called
cancellous bone
spongy bone is found at the
- ends of long bones, called epiphyses
- skull
- bodies of vertebrae of the spinal column
- ribs
based on embryonic development, bones can either be
- cartilage or endochondral
- dermal or membranous
bone that develop by endochondral ossification
cartilage bones
cartilage bones are found in
- bones of the limbs
- ribs
- sternum
connective tissue consisting of resting cartilage cells, lying in groups or in isolation is spaces
cartilage
resting cartilage cells
chondrocytes
avascular connective tissue
cartilage
vascular connective tissue
bone
3 types of cartilage tissues
- hyaline cartilage
- elastic cartilage
- fibroblastic cartilage
- few or no collagenous fibers
- numerous chondrocytes that divide interstitially
- perichondrium is present
hyaline cartilage
- abundant in fibers where chondrocytes also occur in groups or in isolation
- perichondrium is present
elastic cartilage
- has much collagenous fibers
- very few chondrocytes that occur in parallel rows
- perichondrium is not present
fibroblasts
these consist the hyaline cartilage
- young cartilage bones (nasal septum & ensiform cartilage)
found in the pinna or the elastic outer ear, epiglottis, and Eustachian tube
elastic cartilage
these consist the fibrocartilage
- intervertebral disc pads
- symphyses of the coxae
- connective tissue between the muscle and tendons
also called the fat tissue
adipose
this adipose tissue occurs in the nape and groin, as well as in the axilla
brown adipose tissue
this adipose tissue is deposited where excess organic fuel is stored for future use
white adipose tissue
ground tissue of soft organs like the liver, spleen, and lymph nodes
reticular tissue
connective tissue of the early embryonic stage retained in the umbilical cord
embryonic connective tissue
gelatinous material in the ground tissue which surrounds numerous seemingly spherical fibroblastic cells
jelly of Wharton
extracellular fluid in the body that is considered histologically as a kind of connective tissue in having a fluid extracellular matrix and the cellular components
blood
fluid extracellular matrix
plasma
cellular components
corpuscles
