Anatomical Position - Refrence Position in Anatomy. Upright, Arms Hanging with palms forward, thumbs
away with feet pointing forward
Anatomical Planes - Imaginary planes that divide the body
Anatomy - Study, classification, and description of organs
Anatomical Regions - Areas of the human body defined by landmarks
Directional Terms - Describe positions and relation of various structures of the body
Gross Anatomy - Study of larger structures (seen with the naked eye)
Homeostasis - Process used to maintain stable conditions for survival
Microscopic Anatomy - Study of structures that can only be seen with a microscope or other devices
Physiology - Scientific study of chemistry and physics of the body structures
What are the Six levels of Organization in the Human Body? - Chemical, Cellular, Tissue, Organ, System,
Organismal
Chemical Organization - Beginning level, subatomic particles, atoms, molecules
Cellular Organization - Smallest, most numerous structural unit
What are the 3 main parts of a cell? - Plasma membrane, Cytoplasm, Nucleus
,Tissue Organization - Similar Cells grouped to perform a specific function. 4 main parts
What are the 4 main parts of Tissue Organization? - Epithelial, Connective, Muscular, Nervous
Epithelial Tissue - Forms outer covering of the body and lining of different body systems.
Connective Tissue - Supporting tissue and most widespread. Surrounds cells, organs, muscles, joints.
Acts as frame works
Muscular Tissue - Provides for all body movement. 3 Types are skeletal, smooth, and cardiac
Nervous Tissue - Most complex tissue. Make up brain, spinal cord, and nerves. Require more oxygen and
nutrients than other tissue
Organ - More complex than tissue. Of two or more tissue types to perform specific function
System - Group of organs working together to meet physiological needs of the body. 11 major systems
Organismal - Highest level of organization. Everything working independently to perform necessary
physiological functions
Functions of Human Life - metabolism, responsiveness, movement, development, reproduction
Metabolism - Sum of all anabolic and catabolic reactions
Anabolism - Small molecules combined to larger, more complex molecules
Catabolism - Larger molecules are broken down to smaller, more simple molecules
, Responsiveness - Ability to adjust to changes in internal and external environment
Movement - Motion of whole body, individual organs, single cells, and even tiny organelles inside cells
Development - Changes the body goes through in life. Includes differentiation, where cells become
specialized, and growth and repair, where the body increases in size.
Reproduction - Formation of new cells for growth. Carried out by male and female reproductive systems
Nervous System - Detects changes from balanced state. Sends nerve impulse messages to organs that
can counteract the change
Endocrine System - Corrects change by secreting hormones into the blood
Feedback System - Maintains Homeostasis through receptors, control centers, and effectors
Sensor in a Feedback Loop - Monitors change. Sends input from nerve impulses and chemical signals to
the control center
Control Center in a Feedback Loop - Evaluates input from receptors and generates output
Effector in a Feedback Loop - Receives output from control center and responds to change the
controlled condition
Negative Feedback System - Feedback Loop that reverses situation and returns value to normal range
Positive Feedback System - Feedback Loop that strengthens a change rather than reversing it
Anterior View - Front View
