Anatomy & Physiology Lecture

Feeling a structure with hands, such as palpating a swollen lymph node or taking a pulse.

Study of Structure

Study of function physiology

Is listening to natural sounds made by the body, such as heart and lung sounds.

The examiner taps on the body, feels for abnormal resistance, and listens to the emitted sound for signs of abnormalities such as pockets of fluid or air

Ultimately, the functions of the body results from its individual cells. To see those, we usually take tissue specimens, thinly slice stain them. and observe them under microscope. This approach is called

The"Father of medicine" however is usually considered to be the Greek physicans

1839 Botanist and Zoologist, concluded that all organs were composed of cells. Although it took another century for the idea to be generally accepted. Its became the first tenet 
of the cell theory.

Perhaps the most important break through in bio medical history; all functions of the body are now interpreted.

The number of subjects(animals or people) used in a study is the

In this procedure, neither the subject to whom a treatment is given nor the person giving it and recording the results knows whether that subject is receiving the experiment treatment or placebo

The principle of theory of how evolution works. This brings about the genetic change in the population that contributes evolution

Standing and walking on two legs-easier

Is a group of organs with unique collective functions, such as circulation, respiration, or digestion

Structure composed of two or more tissue types that work together to carry out a particular function

Is a mass of similar cells and cell products that forms a discrete region of an organ and performs a specific function

Are smallest unit of organisms that carry out all the basic functions of life; Nothing smaller then a this is considered alive

Are microscopic structure n a cell that carry out its individual functions.  Ex: Mitochondria, Centrioles, and lysosomes

Although the environment around an organism changes, the organism maintains relatively stable internal conditions. This ability to maintain internal stability is called

The fundamental mechanism that keeps a variable close to its set point is? A process in which the body senses a change and activities mechanisms that negate or reverse it. By maintaining stability in this, it is the mechanism for maintaining health

Because feedback mechanism alter the original changes that triggered them (temperature, for example), they are often called 

Is a structure that senses a change in the body. Such as the stretch ________ that monitor blood pressure

Such as the cardiac center of the brain, is a mechanism that processes this information, relates it to other available information( for example, comparing what the blood pressure is with what should be), and "makes a decision" about what the appropriate response should be

Is the cell or organ that carries out the final corrective action

Is a self-amplifying cycle in which a physiological change leads to greater change in the same direction, rather than producing the corrective effects of 

Is an explanatory statement or set of statements derived from facts, laws, and confirmed hypothesis

Is information that can be independently verified by any trained person

Can be applied to data

A substance with no physiological effect on the body

Consist of subjects that are as much like treatment group as possible except with respect to the variable being tested

Living things exhibit a far higher level of organization than the nonliving world around them.

Living matter is always compartmentalized into one or more cells

Living things take in molecules from the environment and chemically change them into molecules that form their own structures, control their physiology, or provide them with energy.Is the sum of all this internal change
