What is anatomy?
"A cutting up" (Gross Anatomy), understaning component parts, The study of internal and external structuresof the body and the physical relationships among body parts
How has the body evolved homeostasis?
The body has evolved this feedback something that happens will cause something to happen in the future ex. blood drings heat to the surface to radiate heat
What is Homeostatic regulation?
The adjustment to physiological systems to to preserve homeostasis
Toward the center
What is Homeostasis?
Refers to the existence of a stable environment, to survive every organism must maintian homeostasis, it is ablsolutely vital
Referring to the midline of the body (mesial), Toward the body's longitudinal axis, away from the midsagittal plane
What is systematic anatomy?
The study of the structure of organ systems, such as the skeletal system, muscular system

Made of muscle
What are the three parts of the regulatory system?
1. A receptor sensitive to env. change (stimulus)
2. A control center (integrationcenter) which recieves and processesthe info supplied by the receptor
3. An effector, a cell or organ that responds to the commands of the control center and whose activity oppses or enhances the stimulus
What is disection?
"To cut apart"
Deeper within, more internal
What is cytology?
The study of one cell or a group of similar cells, microscopic study of cells

What is anabolism?
Enzyme activity making proteins from amino acids or hemoglobin
What is gross anatomy?

Anatomy on a macroscopic level, involves the examination of relatively large srtuctures
What is negative feedback?
An effector activated by the control center either opposes or eliminates the stimulus
ex. pregnancy during pregnancy, birth control
What is Embryology?
The study of embyonic development focusing on the first 2 months after ferilization
upper most, above, at higher level, in humans toward the head
What is apoptosis?
Programmed cell death
What is the control center for thrmoregulation?
What is Histology?
Microscopic anatomy of cells and tissues
What is the primary mechanism for Homeostatic regulaiton?
Negative Feedback-It provides long term control over internal conditions and systems
What are the levels of Organization?
Organism level
Organ System level
Organ level
Tissue level
Cellular level
Chemical or molecular level
What is positive feedback?
The initial stimulus produces a response that exaggerates or enhances it's effects ex. distortion of the uterus leads to further distortion (labor)
What is developmental anatomy?
Deals with the changes in form that occur during the period b/w conception and physical maturity
What is metabolism?
All the chemical events occuring within the living unit
What is an Organ system?
Groups of organs that function together in a coordinated manner
Farther from the midline, awat from the body's longitudinal axis, toward the midsgittal plane
What does endo- mean?
What do cells have to have to survive?
A constant environment
What does peri- mean?
What is extrinsic regulation?
Results from activities of the nervous or endocrine system, two organ systems that adjust or control the activities of many systems simultaneously
What is physiology?
The study of the function of anatomical structures, human physiology is the study of the functions of the human body

The nose
Farther from the origin or point of attachment
Saggittal Plane
Separates right and left protions
What is Catabolism?
Enzyme activity that breaks down something from larger to smaller ex. digestion
What is Autoregualtion (intrinsic regulation)?
Occurs when the activities of a cell, tissue, organ, or organ system adjust automatically in responce to some environmental change
