Anterior (ventral)
toward or at the front of the body
Posterior (dorsal)
toward or at the front of the body
Medial
toward or at the longitudinal axis of the body
Lateral
Away from the longitudinal axis of the body
Intermediate

Promximal
closer to the origin of the body part of the point of attachment of a limb to the body trunk
Distal
farther from the origin of a body part of the point of attachment
Superficial (external)
toward or at the body surface
Deep (internal)
away from the body surface, more internal
Sagittal plane
vertical plane that divides the body into right and left parts
Midsagittal (median) Plane
divides the body exactly in the midline
Parasagittal plane
all other sagittal panes offset from the midline
Frontal (coronal) plane
any pane dividing the body exactly in the midline
Transverse (horizontal) Plane

Oblique Plane
cuts made diagonally between the horizontal and vertical plane
Dorsal Body Cavity
Composed of two smaller cavities: cranial and vertebral
Cranial Cavity
Contains Brain
Vertebral Cavity
Contains spinal cord
Ventral Body Cavity (coelom)
Houses internal organs of the body collectively called the viscera, divided into two smaller cavities
Thoracic Cavity
Contains Pleural cavity, Mediastinum, Pericardial Cavity
Pleural Cavity
right and left; contains lungs
Mediastinum
space between pleural cavities; contains thymus, lymph vessels, esophagus, trachea and nerves
contains pericardial cavity
Pericardial Cavity
located in the mediastinum, contains the heart
Abdominopelvic Cavity
Contains abdominal and pelvic cavities
Abdominal Cavity

Synovial Cavity
joint cavities filled with synovial fluid
X-ray
projects high energy electromagnetic radiation against an area of the body with a metal plate behind it
Computed Tomography (CT)
patient lies on a platform while the computerized axial tomography (CAT) generates multiple xrays as it rotates around the patient
Magnetic Resonance Image (MRI)
uses electromagnets and radiowaves to scan patients
Positron Emission Tomography (PET)
uses short-lived radioactive contrast that will travel to areas with high metabolic activity such as cancer
