Regional -
anatomical
organisation
of specific
areas of the
body
Systemic -
structure of organ
systems. e.g.
skeletal system
Developmental - the
changes in form between
conception and full maturity
Embryology - the study of
the first 2 months of
development.
Clinical -
subspecialities
important in
clinical practice
Microscopic
Anatomy - anatomy
of structures that
can't be seen without
magnification.
Cytology - the study of
the internal structure of
individual cells
Histology - the
examination of
tissues
Physiology
Cell - the
study of the
functions of
cells
Organ - the study of
the function of organs
Systemic - the study
of the organ system
functions
Pathological - the study of
the effects of disease on
organ and organ system
functions
Levels of Organisation
Chemical/Molecular
- atoms
Cellular - cells
and their
organelles
Tissue - tissues, cells
that work together to
perform specific
functions
Organ - groups of tissues that work
together to perform several functions
Organ System - groups of
organs that work together
Organism - all organ systems
working together to form a
fully functioning organism
Organ Systems
Integumentary - protects
against the environment,
regulates body temp and
provides sensory information
Skeletal
Muscular
Nervous
Endocrine - directs long term changes
in organ systems, adjusts metabolic
activity, controls structural and
functional changes in development
Cardiovascular
Lymphatic
Respiratory
Digestive
Urinary
Reproductive
Homeostasis
Autoregulation - the organ
system automatically alters its
activites in response to an
environmental change
Extrinsic regulation -
a result of the nervous
or endocrine system,
the 2 systems that
control or adjust the
activity of other organ
systems
The mechanism
Receptors - sensitive to stimuli
Control centre - receives
processes and then
sends commands out
Effectors - cells or
organs that respond
to the commands of
the control centre
Negative Feedback
counteracting a
change in the
environment
control centre -
hypothalamus
normally maintains
a narrow range
rather than a single
value
Positive Feedback
exaggerating a
change in the
environment
it rests at a
state of dynamic
equilibrium
Anatomical Terms
Superficial Anatomy
locating structures
on or near the
body surface
the normal position for
anatomical position is
palms facing forward and
feet together
Supine - when in
anatomical position
lying down face UP
Prone - when in
anatomical position
lying down face DOWN
Anatomical Landmarks
Anatomical Regions
Anatomical Directions
Sectional Anatomy
Planes and Sections
Body Cavities
they protect
against shocks
and impacts
the allow for significant
changes in size and
shape of organs
Thoracic cavity
contains the
lungs and heart
also contains associated
organs of the respiratory,
cardiovascular and
lymphatic systems, the
inferior portions of the
esophagus and the thymus
it is divided into the
left and right plural
cavity seperated by
the mediastinum
the mediastinum contains the
pericardial cavity and connective
tissue that supports the esophagus,
trachae, thymus and the major blood
vessels that start or end at the heart.
Abdominopelvic Cavity
contains the
superior
abdominal cavity
and the inferior
pelvic cavity
the abdominal cavity contains
the peritoneal cavity which is
the lining around the organs in
the abdomen: liver, stomach,
spleen, small intestine and
most of the large intestine.
the pelvic cavity
the bones of the pelvis
form the wall of the cavity
it contains the
reproductive
organs, bladder and
the distal portion of
the large intestine
the kidneys and pancreas lie
between the peritoneal lining
and the muscular wall of the
abdominal cavity - they are
retroperitoneal
