TISSUES
CONNECTIVE TISSUE
cartilage
-
fibrocartilage
-
location
intervertebral discs, pubic symphysis, discs of knee joint
hyaline
Function
supports and reinforces, serves as resilient cushion, resists compressive stress
location
embryonic skeleton, ends of long bones in joint cavities, costal cartilages of the ribs, nose, trachea and larynx.
bone
function
supports and protects, provides levers for the muscles to act on, stores calcium , minerals, and fat; marrow inside is the cite for blood cell formation
-
Dense
regular
function
attaches muscles to bones or to muscles, attaches bones to bones, withstands great tensile stress when pulling force is applied in one direction
location
tendons, ligaments, aponeuroses
elastic
function
Allows recoil of tissue, maintains flow of blood through arteries, aids passive recoil of lungs.
location
walls of large arteries, within certain ligaments associated with the vertebral column . within walls of the bronchial tubes.
irregular
function
can be exerted in many directions, provides structural strength
location
fibrous capsules of organs and of joints, dermis of the skin, submucosa of digestive tract
blood
-
Function
transport respiratory gases, nutrients, wastes, and other substances
Loose
adipose
Location
under skin in hypodermis, around kidneys and eyeballs, within abdomen, in breasts.
Function
provides reserve food fuel, insulates against heat loss and supports/protects organs
reticular
Location
lymphoid organs (lymph nodes, bone marrow and spleen)
Function
fibers form a soft internal skeleton that supports other cell types including white blood cells, mast cells and microphages
areolar
Location
widely distributed under epithelia of body, forms lamina propria of mucuos membranes, packages organs, surrounds capillaries
Function
wraps and cushions organs, plays important role in inflammation, holds and conveys tissue fluid
-
MUSCLE TISSUE
cardiac
Functon
as it contracts, it propels blood into circulation, involuntary control
-
-
skeletal
function
voluntary movement, locomotion, manipulation of the environment , facial expression
-
NERVOUS TISSUE
function
transmit electrical signals from sensory receptors and to effectors that control the activity of the effector organs
Location
brain, spinal cord, and nerves
EPITHELIAL TISSUE TYPES
Simple (one layer)
Squamous (flat cells)
-
Location
Kidney glomeruli, sacs of lungs, lining of heart, blood vessels, lining of ventral body cavity.
-
Columnar (tall cells)
Location
Nonciliated: lines most of the digestive tract, gallbladder, and exctretory ducts.
-
Function
Absorption, secretion of mucus, enzymes and other substances. The ciliated type propels mucus by ciliary action
