- dense type
kinds of special CT
- bone
- cartilage
- adipose
- blood
examples of loose type / areolar CT proper
- fascia
- hypodermis
examples of dense type CT proper
- tendon
- ligament
5 other classification arrangement of connective tissues
- CT Proper
- Specialize CT
- Embryonic CT
- Supporting CT
- Hematopoietic
dense regular or dense irregular CT
CT Proper
reticular and elastic tissue are also classified as ______
specialized loose CT
includes mesenchymal CT and mucous CT
embryonic CT
bone and cartilage
supporting CT
specialized CT in which cells are suspended in the intercellular fluid;
blood and bone marrow
hematopoietic
dense connective tissue proper can be divided into _____ and _____
regular and irregular
dense collagenous tissues are exemplified by ____ and ____, as well as _____ and ____
- tendons and ligaments
- fascia and aponeurosis
a thin casing of CT that surrounds and holds every organ, blood vessel, bone, nerve fiber and muscle in place
fascia
thin sheath of CT that helps connect muscles to other body parts
aponeurosis
aponeurosis is similar to ______ in terms of movement and flexibility
tendons
this type of dense connective tissue are exemplified by loose areolar CT present in the serosa in the basement membrane and even in the lamina propria of the mucus membrane or mucosa
Loose CT
types of cells that may be found in the areolar CT
- leukocytes
- most cells and macrophages
- fibroblasts
- numerous reticular and adipose cells
2 specialized and supporting CT
- bone
- cartilage
Ct disposed into ossified lamellae or layered organic matrix surrounding resting bone cells in lacunae
bone
resting bone cells
osteocytes
bone matrix is chiefly _____
collagenous
a kind of glycoprotein;
bound to certain proteoglycans that hold inorganic materials and various salts of Fe, Mg, K, and P
collagen
4 classifications in which bones are based on:
a. region located
b. histological origin
c. shape
d. disposition of bone matrix
histological origin of bones could be
- endochondral
- membranous
shape of bones could be
- long
- short
- flat

disposition of bone matrix could be
- spongy / cancellous or compact
this bone is found in diaphysis and periosteum of long bones
compact bone
examples of long bones

- tibia
- bones of digits
also known as osteon
haversian system
also known as cancellous bone and is found on the ends of epiphyses (a long bone)
