Key Concepts and Definitions

Atoms, Molecules, and Chemical Bonds

Understanding the chemical basis of life is essential for studying anatomy and physiology.

• Atom: The smallest unit of matter, consisting of protons, neutrons, and electrons.

• Molecule: Two or more atoms bonded together.

• Chemical Bond: The force holding atoms together in molecules. Types include ionic, covalent, and hydrogen bonds.

• Organic Compounds: Molecules containing carbon, typically found in living organisms (e.g., carbohydrates, proteins, lipids, nucleic acids).

• Inorganic Compounds: Molecules not containing carbon-hydrogen bonds (e.g., water, salts).

Example: Water (H2O) is an inorganic compound essential for life; glucose (C6H12O6) is an organic compound used for energy.

Cell Structure and Function

Cells are the basic units of life, with specialized structures (organelles) performing distinct functions.

• Cell Membrane: A phospholipid bilayer controlling entry and exit of substances.

• Organelles: Structures such as the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus.

• Function: Cells carry out metabolism, growth, and reproduction.

Example: The mitochondrion is the site of cellular respiration, producing ATP.

Tissue Types

There are four primary tissue types in the human body, each with unique characteristics and functions.

• Epithelial Tissue: Covers surfaces and lines cavities; functions in protection, absorption, and secretion.

• Connective Tissue: Supports and binds other tissues; includes bone, cartilage, blood, and adipose tissue.

• Muscle Tissue: Responsible for movement; includes skeletal, cardiac, and smooth muscle.

• Nervous Tissue: Conducts electrical impulses; includes neurons and supporting glial cells.

Example: Skeletal muscle tissue enables voluntary movement; nervous tissue transmits signals throughout the body.

Homeostasis

Homeostasis is the maintenance of a stable internal environment, crucial for health and function.

• Negative Feedback: A process that reverses a change to maintain balance (e.g., regulation of blood glucose).

• Positive Feedback: A process that amplifies a change (e.g., blood clotting).

Example: Body temperature regulation involves negative feedback mechanisms.
