A&P and Characteristics of Life
The scientific study of the structure of the body and the relationship of its parts.
What is anatomy
The smallest particle of an element.
Also known as the plasma membrane or phospholipid bilayer.
What is the cell membrane?
Cover and protect the surface of the body, cover and line certain internal structures, and line cavities, form glands, and specialize in moving substances into and out of the blood during secretion, absorption, and excretion.
What is epithelial tissue?
The most rigid of the connective tissue because of its hard, mineralized matrix.
What is bone?
The scientific study of the processes and functions the body that support life.
What is physiology?
Forces that hold atoms together in a molecule.
What is a chemical bond?
The cell organelle that is found in cells that produce protein.
What is rough endoplasmic reticulum?
The most abundant tissue in the body.
What is connective tissue?
A sheath, a sheet of connective tissue that forms to attach, enclose, and separate muscles and other internal organs.
A condition in which the body's internal environment remains relatively constant within physiological limits.
An atom that has either gained or lost an electron resulting in either a positive or negative charge.
What is an ionic bond?
The powerhouse of the cell.
What is the mitochondria?
Tough and strong fibers that have minimal stretch capability that have a high degree of tensile strength.
What are collagenous fibers?
The only type of muscle under voluntary control.
What is skeletal muscle?
A chemical reaction that occurs in cells to effect the transformation, production, or consumption of energy.
What is metabolism?
When two or more atoms share electrons.
What is a covalent bond?
Processes and packages protein and some carbohydrates for distribution to other parts of the cell or for secretion from the cell.
What is the Golgi apparatus?
Ligaments and tendons are composed of this type of connective tissue.
What is dense irregular connective tissue?
The functional unit of the nervous tissue/system.
What is a neuron?
The movement of fluids, nutrients, sections, and waste products from one area of the body to another.
What is circulation?
Chemical reactions that use energy as they going simple molecules to form more complex molecules of carbohydrates, lipids, proteins, and nucleic acids.
What is anabolism?
Small, fingerlike projections of the cell membrane that serve to increase the surface area.
What are microvilli?
Type of cartilage found in intervertebral discs and in the pubic symphysis.
What is fibrocartilage?
Muscle tissue that is found only in the heart.
What are cardiac muscle fibers?
