Answer:
1) myelin sheath -- A) Fatty insulating envelope that surrounds the core of a nerve fiber or axon and that facilitates the transmisison of nerve impulses. It is formed from the cell membrane of the Schwann cell in the peripheral nervous system and from oligodendroglia cells.
2) Intercalated disc -- B) Structure that contains gap junctions and desmosomes. The gap junctions, which are protein lined tunnels, allow direct transmission of the depolarizing current from cell to cell, across the chambers of the heart, so that the cells contract in unison.
3) Cell Body -- C) Is the spherical part of the neuron that contains the nucleus, also called the soma. It connects to the dendrites, which bring information to the neurons, and the axon, which sends information to other neurons
4) Axon -- D) Long, thin projection of a nerve cell
5) Dendrites -- E) Projections of a neuron that receive signals from other neurons
6) Nodes of Ranvier -- F) Gaps in the myelin sheath coating on the neural axon
7) Cardiac Muscle -- G) Involuntary, striated muscle that is found in the walls of the heart
8) Terminal Bulb -- H) Also called axon terminals. It refers to the axon endings that are somewhat enlarged
9) Striation -- I) Any of the alternating light and dark crossbands that are visible
10) Skeletal Muscle -- J) A muscle that is connected at either or both extermities
11) Smooth Muscle -- K) Muscle tissue that contracts without conscious
