shape,formation (its most common use is as a suffix, although the term includes a word root, plas, and a suffix, -ia)
something shaped (may also be used as a word root)
the study of cells
someone who studies cells
three parts of a cell
cell membrane, cytoplasm, and nucleus
outer boundary of a cell. composed of mostly protein and lipids (fats), It regulates the movement of materials in and out of cell
forms the main substance of the cell and consist of a thick fluid that contains functional packets known as organelles. The organelles perform most of the cells functions including release and storage of energy
part of the cell that contains the genetic material called DNA. DNA contains more than 30,000 genes.
a combination of similar cells that share a common goal, such as providing movement, protection, or secretion.
study of tissues
-consists of cells that are arranged closely together.
-cells may be flat, cubed shpaed or columnar
- most epithelial tissues cover body surfaces and line body cavities forming a protective sheet over other tissues.
-consists of widely scattered cells that are surrounded by extracellular material.
-connnective describes the tissues general function of
connecting cells and tissues to support organs
-the tissue provides support for softer parts of the body to protect them from injury
- forms bone and cartilidge as well as fat and blood
-consist of cells that are specialized to contract.
-three types of muscle tissue:
1. skeletal- forms muscles that attach to bones. Produce heat which warms your body when you are cold
2.smooth- located in the walls of the hollow organs such as stomach or intestines
3.cardiac- forms wall of the heart and produce the hearts contractions that keep blood flowing
consists of specialized cells called neurons, that carry information in the form of electrochemical impulses. Neurons along with neurogilial cells form the brain spinal cord and nerves
an x shaped structure in cells nucleus that bears DNA.
a thick fluid that contains organelles and forms the main substance of the cell
supportive cells within nervous tissue
the part of the cell that contains the DNA
a structure made of two or more different types of tissues, that performs a general function in the body
small structures within the cytoplasm that perform most cell functions. such as construction of molecules and the release and storage of energy
a loss of structural organization in a tissue that is permanent
abnormal tissue development
an increase in the number of cells in a tissue, other than by tumor development
the spreading of cancer cells from the primary tumor
improvement or abscence of signs of disease
a malignant tumor of glandular epithelial tissue; abbreviated adeno-ca
