Chapter 1 Test Flashcards
Study of how those parts work
Physiology
Study of all our parts
Anatomy
Study with the unaided eye
Gross anatomy
What does “unaided” mean
No magnification
The use of plain X-rays
Radiological anatomy
Use of X-ray films
Cine radiography
Scans the body with X-rays from different angles and combines them by computer to provide cross sectional image
Computer tomography (CT)
Sound waves are directed into the body, image is obtained on basis of echoes produced
Sonography
Interior of hollow organs can be viewed by passing a flexible tube with light and camera along them
Endoscopy
Study with the use of microscope
Histology
Deals with the functions of body parts
Physiology
Study of the mind, emotions, and behaviors
Psychology
Study of the causes and effects of diseases
Pathology
Study of how various traits are transmitted
Genetics
Name the characteristics of life
Movement, responsiveness, growth, reproduction, respiration, digestion, absorption, circulation, assimilation, excretion
Combination of the 10 characteristics of life
Metabolism
Requirements of organisms
Water , food, oxygen, heat, pressure
What depends on the quantities and qualities of these factors to maintain life?
Survival
To maintain a stable internal environment
Homeostasis
Three things that keeps homeostasis maintained
Receptors
Set point
Effectors
Levels of organization
Chemical level, cellular level, tissue level, organ level, system level
Atoms join to form molecules which combine to make organelles
Chemical level
Basic structural and functional unit of life
Cellular levels
Groups of cells having a common origin become specialized for certain functions
Differentiation
Cells are organized into tissue
Tissue level
Tissues are organized into organs
Organ level
Organs are organized into systems and they make up an organism
System level
One cell has to do all the functions and is more complex cell to cell, that one cell is more complex than we are

Reproduce
Reproduction
A body part in above another part or is closer to the head
Superior
A body part is below another body part or is toward the feet
Inferior
Towards the front (ventral)
Anterior
Towards the back (dorsal)
Posterior
An imaginary midline dividing the body into equal right and left halves. A body part is this if it is closer to this line than another part
Medial
Toward the side with respect to the imaginary midline
Lateral
Describes a body part that is closer to a point of attachment than another body part
Proximal
Body part is farther from a point of attachment than another body part
Distal
Situated near the surface
Describes the location of certain blood vessels
Superficial or peripheral
Describes parts that are more internal
Deep
Refers to a lengthwise cut that divides the body into right and left portions
Sagittal
If a section passes along the midline and divides the body into equal parts, what is it called
Median
Refers to a cut that divides the body into superior and inferior portions
Transverse
Refers to a section that divides the body into anterior and posterior portions
Coronal
A cut across the structure
Cross section
An angular cut
Oblique section
Lengthwise cut
Longitudinal section
Upper middle region of the abdominal area
Epigastric
Lie on each side of the epigastric region
Left and right hypochondriac regions
Refers to the middle portion of the abdominal region
Umbilical region
Lie on each side of the umbilical region
Left and right lumbar regions
Lower middle portion of the abdominal region
Hypogastric region
Lie on each side of the hypogastric region
