Exam 1 Flashcards
the study of structures and relationships between structures of the human body
anatomy
deals with structures that are macroscopic; observable with the naked eye
gross anatomy
deals with structures too small to be seen with the naked eye
microscopic anatomy
study of the functions of specific organ systems and cellular/molecular events; how all elements carry out processes for necessary life
physiology
what a structure can do depends on its specific form
principle of complementarity of structure and function
Function is dependent on _____, and the form of a structure is related to its _____.
structure, function
levels of structural organization:
atom, molecule, organelle, cell, tissue, organ, organ system, organism
smallest unit of life
cell
protection, support, and movement
integumentary, skeletal, and muscular
communication and integration
endocrine and nervous
defense and assimilation
lymphatic and immune
gas exchange
respiratory and cardiovascular
transport
circulatory
absorption and excretion
digestive, reproductive, and urinary
reproduction
male and female reproductive
the body is erect, palms face forward, and thumbs point away from the body, eyes facing forward, feet flat on the floor, arms at the sides (position always assumed)
anatomical position
In anatomical position, right and left refer to the right and left sides of the _____.
person viewed
anatomical terms that refer to specific visible landmarks on the surface of the body
regional terms
body trunk
axial region
arms and legs
appendicular region
flat surfaces that lie at right angles to each other
plane
slice of a structure (how its cut)
section
divides the body or organ into left and right sides
sagittal
produces equal halves
midsagittal
produces unequal halves
parasagittal
divides the body or organ into front (anterior) and back (posterior) portions
frontal/coronal
divides the body or organ into top (superior) and bottom (inferior) portions
transverse/horizontal
divides the body or organ diagonally
oblique
open spaces within the body closed to the outside; contain the internal organs
body cavities
protects/houses the central nervous system
dorsal body
The dorsal body contains:
cranial cavity and vertebral (spinal) cavity
The dorsal body is lined with _____.
meninges
contains the brain; formed by the skull
cranial cavity
contains spinal cord; formed by vertebral column
vertebral (spinal) cavity
anterior and larger of the closed body cavities; houses viscera
ventral body cavity
body organs
viscera
The ventral body cavity is lined with _____.
serous membranes
The ventral body contains:
thoracic cavity and abdominopelvic cavity
body cavity located above the diaphragm
thoracic cavity
contains the lungs
pleura
area between the lungs containing the heart and thymus gland
mediastinum
contains heart and thymus; lies within the mediastinum
pericardium
body cavity that contains diaphragm; arbitrary boundary (no tissue)
abdominopelvic cavity
The abdominopelvic cavity is lined with _____.
peritoneum
The abdominopelvic cavity contains:
abdominal cavity and pelvic cavity
contains digestive organs
abdominal cavity
contains bladder, rectum, and some reproductive organs
pelvic cavity
large, dome-shaped muscle; separates thoracic and abdominopelvic cavities
diaphragm
prevents friction between the organ and the body cavity wall (serosae)
serous membrane
lines body cavity walls
parietal serosa
covers outer surfaces of organs
visceral serosa
unique to heart; most superficial
fibrous
Serous membranes secrete/separated by a thin layer of _____ (lubricant) found in the _____ (area between parietal and visceral).
serous fluid, serous cavity
toward the head
superior
away from the head
inferior
front of the body
anterior (ventral)
back of the body
posterior (dorsal)
away from the midline of the body
lateral
toward the midline of the body
medial
on the same side of the body
ipsilateral
on opposite sides of the body
contralateral
closer to the point of attachment
proximal
away from the point of attachment
distal
toward or at the body surface
superficial
away from the body surface; inner core
deep
contains the abdomen
peritoneum
contains the heart
pericardium
