of the body
Physiology
study of the

physi
nature or physical
sagittal plane
vertical plane that
divides the body into unequal left and right portions
midsagittal plane, midline
sagittal plane that divides the
body into equal left and right halves
frontal plane, coronal plane
vertical plane that divides the body
into anterior (front) and posterior (back) portions
transverse plane
horizontal plane
that divides the body into superior (upper) and inferior
(lower) portions
Ventral
front, or belly side, of
the organ or body
ventr
belly side of the body
Dorsal
the back of the organ
or body
dors
back of the body
Anterior
situated in the front. It
also means on the front or forward part of an organ
anter
front or before
Posterior
situated in the
back. It also means on the back part of an organ
poster
back or toward the back
Superior
uppermost, above, or toward the
head
Inferior
lowermost, below, or toward the feet.
Cephalic
toward the head
Caudal
toward the lower part of the
body
caud
tail or lower part of the body
Proximal
situated nearest
the midline or beginning of a body structure
Distal
situated farthest from the midline
or beginning of a body structure
Medial
the direction toward, or
nearer, the midline
Lateral
direction toward, or nearer, the
side of the body, away from the midline
dorsal cavity
located along the back of the
body and head, contains organs of the nervous system
that coordinate body functions and is divided into two
cranial cavity
located within the skull,
surrounds and protects the brain
spinal cavity
located within the spinal
column, surrounds and protects the spinal cord
ventral cavity
located along the front of the
body, contains the body organs that sustain homeostasis
Homeostasis
the processes
through which the body maintains a constant internal
environment
home
constant
-stasis
control
thoracic cavity,
chest cavity or thorax
surrounds and protects the
heart and the lungs. The diaphragm is a muscle that
separates the thoracic and abdominal cavities
abdominal cavity
contains
the major organs of digestion. This cavity is
frequently referred to simply as the abdomen
pelvic cavity
the space formed by
the hip bones and contains the organs of the reproductive
and excretory systems
abdominopelvic cavity
abdominal
and pelvic cavities as a
single unit
inguinal
groin, which is the crease at the
junction of the trunk with the upper end of the thigh
pelv
pelvis
chondr/i
cartilage
lumb
lower back
ili
hip bone
peritoneum
multilayered
membrane that protects and holds the organs in place
within the abdominal cavity
membrane
a thin layer
of tissue that covers a surface, lines a cavity, or divides a
space or organ
Parietal
cavity wall
parietal peritoneum
outer layer of the peritoneum
that lines the interior of the abdominal wall
mesentery
a fused
double layer of the parietal peritoneum that
attaches parts of the intestine to the interior
abdominal wall
visceral peritoneum
inner layer of the peritoneum that surrounds
the organs of the abdominal cavity
Visceral
relating to the internal organs
