Ch 1 Flashcards
Studies the structure of body parts
Anatomy
Concerns the function of the body
Physiology
Study of large body structures visible to the naked eye
Gross anatomy
Deals with structures too small to be seen with the naked eye
Microscopic anatomy
Traces structural changes that occur throughout the life span
Developmental anatomy
Function always reflects structure(what a structure can do depends on its specific form)
Principle of complementarily of structure and function
Levels of structural organization
Atom-molecule-organelle-cell-tissue level-organ-organ system-organismal
What are the necessary life functions
Metabolism, maintain boundaries, movement
Reproduction, responsiveness
Growth, excretion, digestion
What are the survival needs
Nutrients Atmospheric pressure Normal body temp Oxygen Water
What are the organ systems
Integumentary, muscular, endocrine, nervous, skeletal, reproductive, digestive, cardiovascular, respiratory, lymphatic, urinary, reproductive
Works continuously to maintain homeostasis
Positive feedback
Once homeostasis is met, goes back down
Most widely used
Negative feedback
Dynamic state that operates in limits to attain stability
Homeostasis
Example is oxytocin(child birth) and blood clotting
Positive feedback
Example is body temperature and ADH(water balance)
Negative feedback
What are the control mechanism components
Receptor, control center, effector
What is anatomical position
Body is erect with feet slightly apart. Palms face forward
Toward the head or upper part of a structure(above)
Superior
Away from the head end or toward the lower part of the body(below)
Inferior
Toward or at the front of the body
Anterior
Toward or at the back of the body
Posterior
Toward or at the midline of the body
Medial
Away from the midline of the body
Lateral
Between a more medial and a more lateral structure
Intermediate
