muscle tissue

consists primarily of cells that are specialized for contraction: 3 different types: skeletal, cardiac and smooth

sarcoplasm

the cytoplasm of a muscle cell

sarcolemma

plasmalemma of muscle cell

skeletal muscle tissue

contains very large ylindrical muscle fibers interconncted by collagen and elastic fibers; incapable of dividing; multinucleate; aka. striated voluntary muscle

myosatellite cells

found only in skeletal muscle tissue; aka. a mesenchymal cell that persists in adult skeletal muscle tissue lives in muscle tissue; as a result, skeletal muscle tissue can partially repair itself after injury

skeletal muscle fibers

aka. muscle fibers, incapable of dividing contain actin and myosin filaments arranged in parallel

cardiac muscle tissue

found only in the heart; composed of unicellular branched short cells connected to each other by intercalated discs; also cannot regenerate but lacks myosatellite cells; aka. striated involuntary muscle

striated involuntary muscle

aka. cardiac muscle tissue

smooth muscle tissue

is composed of short, tapered cells containing a single nucleus; found in walls of blood vessels, hollow organs and in layers around various tracts; aka. nonstriated involuntary muscle; can divide and regenerate

nonstriated involuntary muscle

aka. smooth muscle tissue

Neural tissue

is specialized to conduct electrical impulses from one area of body to another; two cell types: neurons and neuroglia

neuroglia

collective name for several types of supporting neural cells.

neurons

aka nerve cells

soma

the neurons cell body containing a large prominent nucleus

dentrites

branching processes that receive incoming messages

axons

aka. nerve fibers
