Chapter 2 Exam 1 Flashcards
an imaginary flat surface that divides the body into two parts.
Plane
vertical plane that divides the body into front and back sections
Coronal/frontal plane
vertical plane that divides the body into right and left sections
Sagittal plane
a horizontal plane that divides the body into upper and lower sections
Transverse plane
Medial direction
moving from either side of the body toward the midline
Lateral direction
moving from the midline toward either side of the body
Superior/cephalad direction
moving toward the head
Inferior/caudad direction
moving toward the tail bone
Distal direction
moving from the trunk of the body toward the end of a limb
Proximal direction
moving from the end of a limb toward the trunk of the body
moves from the outside of the body through the anterior section and then through the posterior section
Anteroposterior
moves from the outside of the body through the posterior sections and then through the anterior section
Posteroanterior
Superior section
upper half of the body
Inferior section
lower half of the body
front of body
Anterior/ventral
back of body
Posterior/dorsal
structures on the surface of the body
External/superficial
structures below the surface and inside the body
Internal/deep
Prone
lying face down
Dorsal or Dorsal supine
lying on the back
within the bony cranium (brain; cranial nerves; and related structures)
Cranial cavity
continuation of the cranial cavity as it travels down the middle of the back (spinal cord; spinal nerves; and related structures)
Spinal cavity
within the chest and is surrounded by the breast bone anteriorly; the ribs bilaterally; and the bones of the spine posteriorly (lungs; trachea; esophagus; heart; diaphragm)
Thoracic cavity
within the abdomen and is surrounded by the diaphragm superiorly; the abdominal wall anteriorly; and the bones of the spin posteriorly
Abdominal cavity
a continuation of the abdominal cavity and is surrounded by the pelvic bones anteriorly and bilaterally and the bones of the spine posteriorly.
Pelvic cavity
the pelvic and the abdominal cavity because it is one continuous cavity with no dividing structure
Abdominopelvic cavity
