What cell structures are usually basophilic?
|
Those that contain nucleic acids, notably the nucleus and ribosomes.

|
What are some unique characteristics of nervous tissue?
|
Composed of neurons and neuroglia, primarily designed to respond to stimuli, all such tissue characterized by axons.
|
|
|
What are some unique characteristics of connective tissue?
|
Involved in structure and support, largely a non-living tissue, cells separated by an extracellular matrix.
|
|
|
What are some unique characteristics of muscle tissue?
|
Contractile tissue, anchored by tendons to bone.
|
|
|
What are some unique characteristics of epithelial tissue?
|
Comprised of a layer of cells, line outside and inside cavities and lumen in body, can secrete and absorb.
