- b a combination of an epithelial layer with an underlying connective tissue layer.
- c are flat sheets of pliable tissue that cover or line parts of the body.
- d a thin cylindrical process that may be very long and carries the nerve impulse to another neuron or another tissue; there is usually only one of these per neuron.
