Module 1 Flashcards
Anatomy
The study of the structural basis of body function
Physiology
The study of the functional relevance of a structure
Functional morphology
The study of anatomy (structure) of organs functional and the reasons behind it
Gross anatomy
The study of structure visible to the naked eye
Surface anatomy
The external structure of the body
Radiological anatomy
The study of internal structure using X-rays and other imaging techniques
Systemic anatomy
The study of one organ system at a time
Regional anatomy
The study of multiple organ systems at once in body given region
Histology
Microscopic anatomy
Histopathology
The microscopic analysis of diseased tissue
Cytology
The study of structure and function of individual cells
Ultra structure
The structure at the molecular level
Inspection
Looking at the body
Palpitation
Feeling a structure with the hands
Auscultation
Listening to sounds made by the body
Percussion
Tapping on the body to feel for abnormal resistance, listening to the emitted sounds
Dissection
Cutting, separating tissues
Exploratory surgery
Opening the body to see what is wrong and what can be done
Medical imaging
Viewing inside the body without surgery
Radiology
A branch of medicine concerned with imaging
Radiography
Photographing internal structures with X-rays
Magnetic resonance imaging (MRI)
A high-resolution technique that uses a magnetic field instead of X-rays
Computed tomography (CT scan)
Imaging thin “slices” of the body using X-rays
Dynamic spatial reconstructor (dsr)
A modified CT scanner that produces 3D video images to show motive and volume changes
Position emission tomography (PET scan)
Allows for the visualization the metabolic state of a tissue using glucose
Sonography
Uses ultrasound waves visualize internal organsm

Organism
Anatomical position
Person standing bright with arms at sides and palms facing forward
Supine
Lying face up (on back)
Prone
Lying face down (on belly)
Saggital Plane
Divides the body or organ into right and left portions
Midsaggital Plane
Passes through the midline of the body; divides the body into right and left halves
Parasagittal Plane
Divide the body into unequal right and left portions
Frontal (Coronal) Plane
Divides the body into anterior (front) and posterior (back) portions
Transverse (axial, horizontal) plane
Passes through body or organ perpendicular to its long axis; divides the body into superior (upper) and inferior (lower) portions
Anterior
Toward the front of the body
Posterior
Toward the back of the body
Ventral
Toward the anterior side
Dorsal
Toward the posterior side
Superior
Above
Inferior
Below
Cephalic
Toward the head or superior end
Rostral
Toward the forehead or nose
Caudal
Toward the tail or inferior end
Medial
Toward the midline of the body
Lateral
Away from the midline of body
Proximal
Closer to the point of attachment or origin
Distal
Farther from the point of attachment or origin
Ipsilateral
On the same side of the body (right or left)
Contralateral
On opposite sides of the body (right and left)
Superficial
Closer to the body surface
Deep
Farther farther form the body surface
Axial
Consists of head, neck (cervical region), and trunk
Thoracic Region
Above the diaphragm
Abdominal region
Below the diaphragm
Appendicular Region
Consists of upper and lower limbs
Segment
Region of limb from one joint to the next
Membrane
A thin sheet of tissue
Viscera
Membranes the enfold or surround internal organs
Cranial Cavity
Enclosed by cranial bones, contains the brain
Vertebral Canal
Enclosed by vertebral column, contains spinal cord
Mediastinum
Space between lungs, occupied by heart, major vessels, esophagus, trachea, bronchitis, thymus
Pericardium
- Outer fibrous pericardium
- Inner serous pericardium
Pericardial Cavity
Between the two layers of the serous pericardium
*Lubricated by the thin film of pericardial Fluid
Pleura
- Inner visceral pleura (surface of the lungs)
- Outer parietal pleura (Lines inside of the rib cage)
- between the layers of the pleural cavity, there is pleural fluid
Abdominopelvic cavity
Consists of the abdominal cavity superiorly and the pelvic cavity inferiorly
Abdominal Cavity
- Contains most digestive organs, spleen, kidneys, ureters
- Extends inferiorly to the brim of the pelvis
Pelvic Cavity
- Is continuous with the abdominal cavity, but below the rim, and is narrower
- Contains the rectum, urinary bladder, urethra, reproductive organs
Peritoneum
- Parietal peritoneum lines the body walls
- Visceral peritoneum enfolds and suspends the abdominal viscera
*Space in the peritoneal cavity contains peritoneal fluid
Retroperitoneal
Organs lie against the body wall with the peritoneum only on anterior side
Intraperitoneal
Organs are encircled by visceral peritoneum; this layer is also called the serosa
Mesentary
Visceral peritoneum forms a single, extensively folded membrane
Posterior mesentary
Anchors digestive organs to the posterior body wall
- includes the MESOCOLON anchoring large intestine
Anterior mesentety
Includes the greater and lesser omentum
Potential Spaces
between body membranes that are pressed together; not actual space, but can be filled with fluid or other matter
Eponyms
Terms that are names after people
