Define:

anatomy-

physiology-

Q: What is meant by the phrase "structure determines function?"

Microscopic Anatomy vs....

Gross Anatomy

 

Anatomy & Physiology-Related Disciplines...How many can you name?

 

 

Levels of Organization of the Body:

 organism

organ systems  

organ -

 

 tissues -

 

  cell -

 

molecules 

 

atoms    

Q: How are these levels of organization related to one another?

ORGAN SYSTEMS (be able to recognize the major organs & basic functions of each!):

Homeostasis - constancy of our internal environment

1. Negative feedback mechanisms - operate in the opposite direction to decrease the original stimulus and/or reduce its effects, thus returning the system back to normal. Examples:____________________________________________________________________

2. Positive feedback mechanisms - work in the same direction to enhance the original stimulus such that the activity is accelerated. Examples:

Q: What organ serves as the body's "thermostat"?

REGIONAL TERMS (Surface Anatomy)  (a foundation of anatomy and physiology!):

abdominal	acromial	antebrachial
antecubital	axillary	brachial
buccal	carpal	cephalic
cervical	costal	crural
cubital	digital	femoral
frontal	gluteal	inguinal
lumbar	mammary	mental
nasal	occipital	oral
orbital	palmar	pectoral
pedal	pelvic	popliteal
sternal	tarsal	umbilical
vertebral

 

Body Cavities:

Major Organs Within Each Cavity

A. Dorsal Cavity

1. Cranial cavity-

2. Vertebral cavity-

B. Ventral Cavity

1. Thoracic cavity

   a. Pleural cavity-

   b. Pericardial cavity-

2. Abdominopelvic cavity

   a. Abdominal cavity-

   b. Pelvic cavity-

Anatomical Position and Directional Terms:

Anatomical position-

Directional terms (know definitions and be able to use in a sentence!):

 

superior	inferior (caudal)
anterior (ventral)	posterior (dorsal)
medial	lateral
proximal	distal
superficial (peripheral)	deep

 

Planes of Section:

Sagittal (midsagittal & median sagittal)

Frontal (coronal)

Transverse (horizontal)

ABDOMINAL REGIONS:

NAME	Major Organs Found Within Each
Epigastric
Right Hypochondriac
Left Hypochondriac
Umbilical
Right Lumbar
Left Lumbar
Hypogastric
Right Iliac
Left Iliac

 

Did you know....?  Nuclear imaging is a technique that produces pictures of select organs (liver, spleen, thyroid, heart) after they absorb radioisotopes injected into the bloodstream.  The scans show the size and shape of the organ and presence of infections and tumors.  A heart scan may also show reduced blood flow (ischemia) which indicates an impending heart attack.  These noninvasive techniques take only a few minutes and side effects from the injections are extremely rare.  Positron emission tomography (PET) scans are another type of nuclear imaging process analyzed by computers very commonly used for brain imaging.
