LECTURE 1:  Introduction to Anatomy and Physiology

Study Outline

 

1.1.  Definition of Anatomy and Physiology:

a.      The science that describes the structure of body parts and their relation to each other is called ______________________, whereas the science that describes body function is called ___________________________.

b.     ______________________ describes the process by which bodies are carefully cut up to observe structure.

 

1.2.  Levels of Organization:

a.      The seven basic levels of organization of the human body are __________________________, ______________________________, __________________________, ______________________________, __________________________, ______________________________, and __________________________.

b.     Two or more atoms join together to form _________________________, but when these atoms represent different ____________________________, the term compound is used.

c.      The basic structural and functional unit of an organism is the __________________________________.

d.     Cells contain small, often membrane bound structures called __________________________________.

e.      The general term for a group of cells that functions together is a __________________________________.

f.       The four basic tissue types are ___________________________________, ___________________________, ________________________________, and ________________________________.

g.      The smallest units of matter that participate in chemical reactions are __________________________________.

h.      ___________________________ consist of two or more tissue types functioning together for a common purpose.

i.       There are ____________________________ different organ systems in the human body.

 

1.3.  Basic Life Functions: 

a.      The five basic life functions are ___________________________________, ______________________________, ______________________________, ______________________________, and ___________________________.

b.     The term which describes all chemical process that take place in the body is _____________________________.

c.      The specific process by which large food molecules are chemically broken down into small nutrients that can be absorbed is called ______________________________.

d.     The process by which new molecules are synthesized is called _____________________________, while the process by which molecules are broken down is called _____________________________.

e.      Waste products are removed from the body through a process known as ____________________________________.

f.       __________________________ is a term that refers to the body’s ability to detect and respond to changes in the internal and/or external environment. 

g.      Movement can occur at the level of the ______________________________, ___________________________, __________________________________, or even ______________________________.

h.      When growth is due to an increase in cell number, this is called __________________________________, whereas hypertrophy refers to an increase in _________________________________.

i.       The process by which cells become specialized is called _____________________________________.

j.       The process by which cells divide to form 2 identical daughter cells is called __________________________ whereas __________________________ refers to the process where the daughter cells have only half the number of chromosomes.  Cells formed as a result of meiosis are called ____________________________________.

 

1.4. Homeostasis:

a.      The fluids that surround cells in our body form the ______________________ environment.

b.     ______________________________ refers to the tendency to maintain relative constancy of the internal environment.

 

1.5. Body Fluid Compartments:

a.      The fluid present within cells is called ______________________________ whereas the fluid present outside cells is called ______________________________.

b.     Extracellular fluids can be further subdivided into ______________________ and __________________________, of which _________________________ is present within blood vessels.

c.      From the standpoint of homeostasis, maintaining constancy of the internal environment involves maintaining the volume and _________________________ of __________________________ fluids at constant levels.

 

1.6. Feedback Systems:

a.      In the example of an individual that passes out due to hypoglycemia, the controlled variable is ____________________________________.

b.     Besides the controlled variable, feedback systems consist of three basic components called the __________________________, _____________________, and one or more ______________________.

c.      In the example of temperature regulation within the home due to the furnace, the _______________________ represents the sensor, the thermostat represents the ______________________ and the furnace represents the ___________________________.  The controlled variable in this case is _______________________________________.

d.     The difference between the actual measurement of a controlled variable and its set point is the _____________________________. 

e.      A system in which the change caused by the effector is opposite to the initial disturbance is called a _______________________ feedback system.

f.       In the example of body temperature regulation, the effectors are ____________________________,  _______________________________, and ________________________________.

g.      In an individual with a fever, the elevation in temperature is caused by an altered __________________________________.

h.      A system in which the change caused by the effector tends to reinforce the initial disturbance is called a _________________________ feedback system.

i.       Examples of positive feedback mechanisms include ____________________, _________________________, and _______________________________.

 

1.7. Basic Anatomical Terminology:

a.      When a subject is in the anatomical position, they are standing erect, facing _________________________________, arms at the side with palms facing _________________________________.

b.     When a subject is lying face down, this is referred to as the _______________________ position, whereas if they are lying down face up, this is ___________________________.

c.      A vertical plane that divides the body into right and left portions is called a ______________________ plane whereas the vertical plane that divides the body into front and back portions is called a _________________________ plane.  When the plane divides the body into equal right and left portions, this plane is called the ______________________________ plane.

d.     A __________________________ plane divides the body into top and bottom portions.

e.      The term which describes a position toward the head is ________________________________; toward the front of the body is ________________________________; away from the mid-sagittal plane is ________________________________; toward the trunk of the body is ________________________________; and on the same side of the body is ________________________________.

f.       The _______________________ cavity contains the brain whereas the vertebral canal contains the _____________________________.

g.      The structure that divides the thoracic and abdominopelvic cavity is the ___________________________________.
