AnaPhy (The Language of Anatomy) Flashcards
Directional Terms, Position, Region
Body is in a standard position; it is important to understand this position because most body terminology used in this text refers to this body positioning regardless of the position the body happens to be in
ANATOMICAL POSITION
It allows medical personnel and anatomists to explain exactly where one body structure is in relation to another

PLANTAR
When preparing to look at the internal structures of the body, medical students make a ________ or _______ ?
make a SECTION or CUT
When the section is made through the body wall or through an organ, it is made along an imaginary line called?
PLANE
If the cut is down the median plane of the body and the right and left parts are equal in size
MEDIAN (MIDSAGITTAL) SECTION
What are the Three Types of Planes?
Median (Midsagittal) Section , Frontal (coronal Plane , Transverse Plane
It is cut along the lengthwise, or longitudinal, plane of the body, dividing the body into right and left parts
SAGITTAL SECTION
What is Frontal Section also called?
CORONAL SECTION
It is a cut along a lengthwise plane that divides the body into anterior and posterior parts
FRONTAL SECTION
What are other sagittal sections?
PARASAGITTAL SECTIONS (para= near)
It is cut along a horizontal plane, dividing the body or organ into superior and inferior parts
TRANSVERSE SECTION
What is Transverse Section also called?
CROSS SECTION
There are two sets of internal body cavities, what are they?
DORSAL AND VENTRAL BODY CAVITIES
This body cavity has two subdivisions which are continuous with each other
DORSAL CAVITY
What are examples of Dorsal Body Cavity?
Cranial Activity & Spinal Cavity
It is the space inside the body skull; the brain is well protected because it occupies the _______ cavity.
CRANIAL ACTIVITY
It extends from the cranial cavity to the end of the spinal cord
SPINAL CAVITY
This body cavity is much larger than the dorsal cavity; it contains all the structures within the chest and abdomen
VENTRAL BODY CAVITY
This cavity is separated from the rest of the ventral cavity by a dome-shaped muscle, the diaphragm
THORACIC ACTIVITY
A central region that separates the lungs into right and left cavities in the thoracic cavity; houses the heart, trachea, and several other visceral organs
MEDIASTINUM
The cavity inferior to the diaphragm
ABDOMINOPELVIC CAVITY
When the body is subjected to physical trauma, the most vulnerable abdominopelvic organs are those within _______?
Within the ABDOMINAL CAVITY
Abdominopelvic cavity is quite large, medical personnel divides it into?
Four more or less equal regions called QUADRANTS
What are the Quadrants?
Right Upper Quadrant, Right Lower Quadrant
Left Upper Quadrant, Left Lower Quadrant
This system is used mainly by anatomist
Nine Regions by Four Planes
It is the centermost region, deep to and surrounding the umbilicus (navel)
UMBILICAL REGION
It is located superior to the umbilical region
EPIGASTRIC
epi = ? ; gastric = ?
epi = upon ; gastric = stomach
Inferior to the umbilical region
HYPOGASTRIC (PUBIC) REGION
hypo = ?
hypo = below
Lateral to the hypogastric region
RIGHT ILIAC (INGUINAL) REGION & LEFT ILIAC (INGUINAL) REGION
iliac = ?
iliac = superior part of the hip bone
lie lateral to the umbilical region and spinal column between the bottom ribs and the hip bones
RIGHT LUMBAR REGION & LEFT LUMBAR REGION
lumbus = ?
lumbus = loins

RIGHT HYPOCHONDRIAC REGION & LEFT HYPOCHONDRIAC REGION
What are the other smaller body cavities?
Oral Cavity and Digestive Cavity
Nasal Cavity
Orbital Cavities
Middle Ear Cavities
Contains the teeth and tongue; this cavity is part of and continuous with the digestive organs, which open to the exterior at the anus
