1_______. Cells respond to stimuli from the environment outside their walls. 2_______. Thus, for example, muscle cells stretch and contract, nerve cells carry signals, endocrine-gland cells manufacture hormones.
There are many different kinds of cells in the human body, but they can generally be classified as follows:
Epithelial cells, which are found in the skin, membranes, and glands. 3_______.
Connective tissue cells, found in bones, cartilage, ligaments, and tendons, make up the supporting tissues of the body.
Muscle cells, which have the power to expand and contract.
4_______.
Blood cells, red and white, found in the blood and the blood-forming organs (bone marrow).

Actually cancer is not one but many diseases. Under the microscope hundreds of different varieties of cancer cells can be identified. Cancer is therefore a group of diseases characterized by abnormal, uncontrolled, «lawless» growth of body cells. Plants and animals are also subject to cancerous growths.
Cells are the fundamental units of all living matter. In the normal process of growth and repair, cells grow and take their places in the economy of the body according to what may be called the «rules of nature». Sometimes, for reasons still unknown, a cell or group of cells breaks the ordinary rules of nature. They behave in a disorderly way; they grow wildly.

The nerve cell is the fundamental unit of the nervous system. 1_______. Typically, a nerve cell looks like an octopus.
It has a central cell body from which tentacles extend. 2_______. The other tentacles or fibers receive impulses and carry them to the cell body; they are called dendrites.
3_______. Like telephone wires running underground, they form a kind of cable, which is enclosed in a flexible tube of connective tissue. This whole cable of nerve fibers is what we ordinarily call a nerve.
4_______. The nerve fibers growing out from them will regenerate, though slowly.

Cancer cells can start in any part of the body, but some sites are more favored. Unfortunately these cells rarely remain where they originate. Clusters or clumps of cancer cells break off and travel in the blood stream to other parts of the body – from the breast to the armpits, for example. This spread of cancer cells is called metastasis.
Cancer cells are definitely different from ordinary cells, and these differences can be observed in tiny sections of tissue examined under a microscope. Identifying cancer cells is an important part of the job of the pathologist.
