Intro to Anatomy Flashcards
ANATOMY
-study of external + internal structures of the body -study of relationship between body parts
PHYSIOLOGY
study of how the body functions +mechanisms
MICROSCOPIC ANATOMY
study of structures that CAN’T be seen w/o magnification
2 types of Microscopic Anatomy
1 CYTOLOGY - study of cells 2 HISTOLOGY - study of tissues
GROSS ANATOMY
*macroscopic study of structures that CAN be seen w/o magnification
3 types of GROSS ANATOMY
1 SURFACE ANATOMY 2 REGIONAL ANATOMY 3 SYSTEMIC ANATOMY
SURFACE ANATOMY
studies superficial anatomical markings
REGIONAL ANATOMY
study of all structures in a specific area of the body
SYSTEMIC ANATOMY
study of the organ systems of the body
6 other types of ANATOMY
1 DEVELOPMENTAL (embryology) 2 COMPARATIVE (considers diff type of animals) 3 CLINICAL (focus on pathological changes during illness) 4 SURGICAL (anatomical landmarks important for surgery) 5 RADIOGRAPHIC (studies structures w use of xrays or ultrasound) 6 CROSS SECTIONAL (use of radiographic technique like CT or MRI scans)
Level of Organization (from simple to complex)
1 Chemical/Molecular 2 Cellular 3 Tissue 4 Organ 5 Organ System 6 Organism
4 most common Elements in human body
Hydrogen 62% Oxygen 26% Carbon 10% Nitrogen 1.5%
5 major classes of Compounds
Water Carb Proteins Lipids Nucleic Acid
11 Organ Systems
1 Integumentary 2 Skeletal 3 Muscular 4 Nervous 5 Endocrine 6 Cardiovascular 7 Lymphatic 8 Respiratory 9 Digestive 10 Urinary 11 Reproductive
Abdominopelvic Quadrants

Abdominopelvic Regions

organs found in EPIGASTRIC region
left lobe of liver
organs found in RIGHT HYPOCHONDRIAC region
right lobe of liver, liver fundus
organs found in LEFT HYPOCHONDRIAC region
stomach fundus, spleen
organs found in UMBILICAL region
small intestines, transverse colon
organs found in RIGHT LUMBAR region
ascending colon
organs found in LEFT LUMBAR region
descending colon
organs found in HYPOGASTRIC region
urinary bladder, appendix, major portion of small intestines
organs found in RIGHT INGUINAL region
cecum, appendix
organs found in LEFT INGUINAL region
sigmoid colon



SECTIONAL ANATOMY
4 types of CUTS
1 SAGITTAL CUT separate left and right
2 TRANSVERSE CUT separate superior + inferior
3 FRONTAL CUT (CORONAL) separate anterior + posterior
4 OBLIQUE CUT separate tissue at an angle


Types of Body Cavities
- DORSAL CAVITY
- CRANIAL CAVITY
- VERTEBRAL CAVITY
- VENTRAL CAVITY
- THORACIC CAVITY
- ABDOMINOPELVIC CAVITY
- ABDOMINAL CAVITY
- PELVIC CAVITY


2 layers of Serous Membranes
PARIETAL LAYER - against the wall of a cavity
VISCERAL LAYER - against the organ within the cavity
3 Regions given to Serous Membranes
PLEURAL - surrounds lungs
PERICARDIAL - surrounds heart
PERITONEAL - surrounds abdominal organs
double sheets of peritoneum (stomach cavity)
mesenteries
subcutaneous layer
component of integumentary system that stores lipids

lumbus

pollex

Maculae Adherens
aka
Desmosomes
small, localized, spotlike anchoring junctions that stabilize adjacent epithelial cells
contains enzymes by free ribosomes within the cytoplasm
peroxisomes
