Unit 1 - Muscle Tissue & Neural Tissue

muscle tissue
consists primarily of cells that are specialized for contraction: 3 different types: skeletal, cardiac and smooth
the cytoplasm of a muscle cell
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
collective name for several types of supporting neural cells.
aka nerve cells
the neurons cell body containing a large prominent nucleus
branching processes that receive incoming messages
aka. nerve fibers
