Chapter 2 The Human Body in Health and Disease A&P Flashcards
is the study of the structures of the body
anatomy
is the study of the functions of the structures of the body
physiology
describes the body standing in the standard position
anatomic position
are imaginary vertical and horizontal lines used to divide the body into sections for descriptive purposes
body planes
is an up-and-down plane that is a right angle to the horizon
vertical plane
is a vertical plane that divides the body into unequal left and right portions
sagittal plane
also known as the midline, is the sagittal plane that divides the body into equal left and right halves
midsagittal plane (midline)
is a vertical plane that divides the body into anterior and posterior portions
frontal plane (coronal plane)
is a flat crosswise plane, such as the horizon
horizontal plane
is a horizontal plane that divides the body into superior and inferior portions
transverse plane
refers to the front, or belly side, of the organ or body
ventral
refers to the back of the organ or body
dorsal
means situated in the front
anterior
means situated in the back
posterior
means uppermost, above, or toward the head
superior
means lowermost, below, or toward the feet
inferior
means toward the head
cephalic
means toward the lower part of the body
caudal
means situated nearest the midline or beginning of a body structure
proximal
means situated farthest from the midline or beginning of a body structure
distal
means the direction toward, or nearer, the midline
medial
means direction toward, or near, the side of the body, away from the midline
lateral
which is located along the back of the body and head, containing organs of the nervous system that coordinate body functions
dorsal cavity
which is located within the skull, surrounds and protects the brain
cranial cavity
means pertaining to the skull
cranial
which is located within the spinal column, surrounds and protects the spinal cord
spinal cavity
which is located along the front of the body, contains the body organs that sustain homeostasis
ventral cavity
also known as the chest cavity or thorax, surrounds and protects the heart and the lungs
thoracic cavity (chest cavity or thorax)
contains primarily the major organs of digestion
abdominal cavity
is the space formed by the hip bones and contains primarily organs of the reproductive and excretory systems
pelvic cavity
means relating to the groin
inguinal
region covered by the lower ribs
hypochondriac regions
region located above the stomach
epigastric region
region located near the inward curve of the spine
lumbar regions
region that surrounds the umbilicus
umbilical region
region located over the hip bones
iliac regions
region located below the stomach
hypogastric region
what are the four quadrants
right upper quadrant (RUQ)right lower quadrant (RLQ)left upper quadrant (LUQ) left lower quadrant (LLQ)
is a multilayered membrane that protects and holds the organs in place within the abdominal cavity
peritoneum
is a thin layer of tissue that covers a surface, lines a cavity, or divides a space or organ
membrane
is the outer layer of peritoneum that lines the interior of the abdominal wall
parietal peritoneum
is a fused double layer of parietal peritoneum that attaches parts of the intestine to the interior abdominal wall
mesentery
is the inner layer of peritoneum that surrounds the organs of the abdominal cavity
visceral peritoneum
means located behind the peritoneum
retroperitoneal
are the basic structural and functional units of the body
cells
is the study of the anatomy, physiology, pathology, and chemistry of the cell
cytology
