A & P Lab Cells and Tissues

How many basic types of muscle tissue are there?

3

How many primary tissue types are found in the human body?

4

How many stages of mitosis are there?

6

True/False All animals cells have a cell wall.

False

True/False The end product of mitosis is four genetically identical daughter nuclei.

False

Epithelial tissues can be classified according to cell shape. ______ epithelial cells are scalelike and flattened.

Squamous

True/False Blood is a type of connective tissue.

True

True/False Endocrine and exocrine glands are classified as epithelium because they usually develop from epithelial membranes.

True

When a cell is not dividing, the DNA is loosely spread throughout the nucleus in a threadlike form called

chromatin

DNA replication occurs during

interphase

During cytokinesis/interphase the cell grows and performs its usual activities.

interphase

All connective tissue is derived from an embryonic tissue known as

mesenchyme

Because these organelles are responsible for providing most of the ATP needed by the cell, they are often referred to as the "powerhouses" of the cell. They are the

mitochondria

All the following are example of connective tissue except

neurons

Of the two major cell types found in nervous tissue, neurons/neuroglial cells are highly specialized to generate and conduct electrical signals.

neurons

Proteins are assembled on these organelles.

ribosomes

The plasma membrane not only provides a protective boundary for the cell but also determines which substances enter or exit the cell. We call this chcaracteristic

selective permeability

This type of muscle tissue is found in the walls of hollow organs. It has not striations, and its cells are spindle shaped.

smooth muscle

Define cell

the structural and functional units of all living things

Groups of cells that are anatomically similar and share a function are called

tissues
