Anatomical Terminology Flashcards
what is the standard anatomical position?
- body upright
- standing straight up
- head and eyes facing forward
- feet flat and forward
- upper limbs to the side
- palms turn forward
prone position
body lying face down
supine position
body lying face up
anterior
toward the head
posterior
toward the tail
dorsal
back side (same as posterior but dorsal refers to animals)
ventral
front/belly side (same as anterior but ventral refers to animals)
superior
closer to the head
inferior
closer to the feet
proximal
near to the attachment of a limb to the trunk
distal
farther from the attachment of a limb to the trunk
lateral
farther from the midline
medial
closer to the midline
planes/sections
imaginary flat surfaces that pass through the body/body parts
types of planes (covered in class)
- sagittal plane
- transverse plane
- frontal plane
- oblique plane
sagittal plane
splits the body into right and left sides
types of sagittal planes
- mid-sagittal: divides equally left and right (through midline)
- para-sagittal: divides unequally left and right
transverse plane/cross-sectional plane
superior (upper) and interior (lower) portions
frontal plane
anterior (front) and posterior (back) portions
oblique plane
any angled plane, excluding horizontal and vertical
viscera
organs of the body (different cavities contain different organs)
body cavity
any potential space/space in the body (can contain organs or other structures)
-potential cavities usually contain fluids
cranial cavity
formed by cranial bones and contains the brain
spinal cavity
contains the spinal cord
- is formed by vertebral column
- have the beginnings of spinal nerves
thoracic cavity (chest cavity)
- protects the thoracic wall (ribs, lungs, heart, muscle)
- has three other compartments/cavities inside of it
The 3 thoracic cavities
- pericardial cavity
- pleural cavity
- mediastinum
pericardial cavity
fluid filled space that surrounds the heart
pleural cavity
two fluid filled spaces that surround each lung
mediastinum
central of thoracic cavity between the lungs (first rib to the diaphragm)
-the diaphragm separates the thoracic cavity from the abdominopelvic cavity
abdominopelvic cavity
contains the abdominal cavity and pelvic cavity
abdominal cavity
stomach, spleen, liver, gallbladder, small and large intestine
pelvic cavity
urinary bladder, internal reproductive organs, portions of large intestine
abduction
lateral movement away from the midline of the trunk in frontal plane
ex. raising arms or legs to side horizontally
adduction
movement medially toward the midline of the trunk in frontal plane
ex. lowering arms or legs to side horizontally
