Classification of Tissue (Pictures)

bone (osseous tissue)

Very vascular osteocytes in lacunae. Hard calcified matrix with collagen.

blood (connective tissue)

blood vessels. Matrix is called plasma.

nervous tissue (neurons)

brain, spinal cord, nerves. Supporting cells (neuroglia) protect, nourish, and insulate the neuron.

skeletal muscle

attaches to bone and skin. Long, striated, multinucliated cells. Voluntary action muscle.

cardiac muscle

Only found in the heart. Involuntary action muscle. Striated and uninuclear.

smooth muscle

walls of hollow organs. Involuntary action muscle. Not striated and uninuclear.

cartilage elastic (connective tissue)

supports external ear. Rubbery solid matrix.

fibrocartilage (connective tissue)

intervertebral disks and knee. Add strength to resist compressional forces.

hyaline cartilage (connective tissue)

Chondrocytes. cartilage in the ribs, nose. Smooth tissue. In articular surfaces -> joints

dense irregular

fibrous capsules of organs and joints

dense regular (dense connective tissue)

tendons and ligaments. Attaches muscle to bone. Main cell is fibroblast.

reticular (loose connective tissue)

spleen

adipose (loose connective tissue)

within abdomen or breasts. Provides reserve food and insulation. Gel like matrix

areolar (loose connective tissue)

packages organs, surrounds capillaries. Gel like matrix. Main calls in fibroblasts

transitional epithelium

urinary bladder

stratified squamous epithelium

lines esophagus

pseudostratified columnar epithelium

lines trachea

simple columnar epithelium

lines digestive track

simple cuboidal epithelium

found in kidneys

simple squamous epithelium

found in lungs
