Tissues Anatomy

Tissue

group of cells with a similar structure and function

Membranes

sheets of tissue with a specific location and function

glands

type of epithelial tissue capable of secretion

adipose tissue

white fat: storage of triglycerides
brown fat: in infants, generates heat
many white blood cells

adipose tissue location and dunction

subcutaneous in areolar connective tissue
store energy, cushion or protection , insulation and heat (brown fat)

fibrous tissue

consists of many parallel (collagen fibers) w/ few fibroblasts

fibrous tissue location and function

outer walls of arteries, tendons, ligament
strength and flexibility

elastic connective tissue

consists primarily of elastin fibers w/ few fibroblasts
recoil from its strechiness

elastic connective tissue location and function

walls of large arteries and lungs
recoil, aids in exhalation and maintaining blood pressure

osteocytes

bone cells

matrix of bone

calcium salts and collagen fibers

what are the arrangements of bone cells called

haversian system or osteon system

location and function of bone cells

skeleton
support, protection, produce blood cells and storage for calcium

cartilage

smooth a flexible; not very strong
direct blood supple nutrients must diffuse through the matrix, so repair is slow

chondrocytes

cartilage cells

cartilage function and locations

joint surface, nose, ear, trachea, and spine
prevent friction, support and cushion

Dense irregular tissue

mostly collagen fibers with variables amounts of elastin fibers

Dense irregular tissue location and function

dermis of the skin
support tissues and organs

muscle tissue

for contractions
muscles only shorten

skeletal muscles

striated or voluntary muscle
cylindrical with its own motor neuron

skeletal muscle location and function

attatched to the skeleton
movement of the skeleton and heat production
voluntary muscle

smooth muscle

involuntary muscle
tapered ends with a single nucleus

smooth muscle location and function

internal organs, arteries and veins, lungs and pupil of eye
depending upon location
- move food
-blood pressure
-pupil size
-dilate or constrict bronchials of lungs

cardiac muscle

branched cells, faint striations, usually a single nucleus
intercalated discs (myocardial cells)

cardiac muscle location and function

heart
pump blood, maintain blood pressure and heart rhythm

nerve tissue

composed of neurons and some specialized neroglia and schwann cells

comprise the central nervous system and the peripheral neuron

synapse

connection of small space between neurons

cell body

contains nucleus and other cellular organelles

axon

carry impulses away from the cell body

dendrites

carry impulses towards the cell body

location and function of nerve tissue

brain and spinal cord, peripheral nerve
specialized cells capable of generating and transmitting electrical impulses

serous membrane

a thin membrane lining the closed cavities of the body

mucous membrane

mucus-secreting membrane lining all body cavities or passages that communicate with the exterior

synovial membrane

lines a joint cavity and produces fluid

peritoneum membrane

the serous membrane lining the cavity of the abdomen and covering the abdominal organs

Leukocytes

white blood cell, in immune system

Erythrocytes

red blood cells, carry oxygen

Hemopoietic tissue

blood forming tissue
