- b are columns of bone within spongy bone; red bone marrow is found in the spaces between the columns.
- c Neurons and muscle cells which exhibit electrical excitability, the ability to respond to certain stimuli by producing actions potentials.

muscular tissue → is a connective tissue with a liquid extracellular matrix and formed elements (cells).
synoviocytes → form a discontinuous layer of cells of synovial membranes and they secrete some components of synovial fluid.
fibrosis → is the process of scar tissue formation when fibroblasts are active in the tissue repair.
membranes → the parts of a neuron which receive stimuli; they are usually short, tapering highly-branched cell processes which are connected to the cell body.
