anatomy and physiology unit 1 chapter 4 connective tissue
adipose loose connective
adipose cells, fat droplets, very dens, highly vascularized.
connective tissue
cells separated from one another by large amount of nonliving extracellular matrix (responsible for the strength of the tissue)
ground substance
(fluid and proteins)- fills the space between cells, "glue"
Dense regular connective tissue
attaches muscles to bones or to muscles, bone to bone.
loose connective tissue
beneath skin, between muscles, beneath epithelial tissues
Dense connective tissue
binds organs together
loose connective tissue
binds organs together, holds tissue fluids; areolar, adipose, reticular.
fluid connective tissue
blood is a connective tissue composed of cells
supporting connective tissue
cartilage and bone
cartilage-Hyaline
collagen fibers, matrix
four classes
connective tissue proper (loose and dense), cartilage, bone, blood.
blood
contained in blood vessels
connective tissue
defending the body against infection
characteristics
degrees of vascularity (cartilage is avascular, dense connective is poorly avascular, others are rich in blood supply.
dense irregular connective tissue
dermis of skin, digestive tract
Dense connective tissue
example: dense regular, dense irregular
cartilage-elastic
external ear, epiglottis
reticular loose connective
fibers, reticular cells
collagen fibers
fibers-provide support, made of the protein collagen which are tough fibers, elastic-made of elastin which is stretchable, reticular-made of collagenous material creating "nets"
reticular loose connective
fivers help support other cells (white blood cells, mast cells, macrophages)
supporting connective tissue
form a strong, durable framework that protects and supports the soft body tissues
cartilage-Hyaline
forms embryonic skeleton, covers end of long bones, ribs, nose, trachea, larynx
Areolar loose connective
gel-like matrix, fibers, macrophages, mast cells (inflammation, white blood cells
bone (osseous tissue)
hear, calcified, collagen fibers, vascularized
connective tissue
holding body fluids
connective tissue
insulation
cartilage- Fibrocartilage
intervertebral discs, pubic symphysis, discs of knees
dense irregular connective tissue
irregular arranged fibers, fibroblast
cartilage- Fibrocartilage
less firm, thick fibers
reticular loose connective
lymph nodes, bone marrow, spleen
cartilage-elastic
maintains shape of structure, great flexibility
Connective tissue
most abundant tissue
characteristics
most diverse and abundant type of tissue
characteristic
originate from embryonic tissue called mesenchyme
Dense regular connective tissue
parallel collagen fibers, fibroblast
Adipose loose connective
provide reserve food fuel, insulation, protects organs
blood
red and white blood cells in plasma
cartilage-elastic
similar to hyaline cartilage, but more elastic fibers in matrix
cartilage- Fibrocartilage
strength, ability to absorb compressive shock
connective tissue
support and binding of other tissues
bone (osseous tissue)
support, protects, stores calcium and other minerals, marrow inside of bones, blood cell formation
cartilage-Hyaline
supports and reinforces, cushioning properties, resists stress
Dense regular connective tissue
tendon (attach muscle to bone) and ligaments (bone to bone), fascia (wraps around muscles)
Dense connective tissue
tendon and ligaments
blood
transport of repiratory gases, nutrients, wastes
connective tissue
transportation
Areolar loose connective
under epithelia (between the skin and muscles), packages organs, surrounds capillaries.
Adipose loos connective
under skin, around kidneys & eyeballs, breasts, abdomen
dense irregular connective tissue
withstands tension, strength
Areolar-loose connective
wraps and cushions organs, involved with inflammation
