wk1 / c1 (a&p defined, levels of structural organization) Flashcards
- what is Human Anatomy
the study of body structure
what is Human Physiology
science of body of functions
(physio - the nature and how of things work and function)
how are Structure and function of the body related in a&p?
Structure mirrors function
subdivisions of anatomy
what are the Subdivisions of Anatomy?
(2)
- surface anatomy
- gross anatomy
subdivisions of anatomy
gross anatomy
can be studied by 2 different approches
(2)
- systematic approch (systematic anatomy)
- regional approch (regional anatomy)
subdivisions of anatomy
histology is the study of -
tissues
(histo means tissues)
subdivisions of anatomy
cytology
is the study of
cellular structures
(cyto means cells)
(ie) cell structure - microvilli
subdivisions of anatomy
This micrograph is typical of an _ and _ examination under light microscopy

histological
and cytological
subdivisions of anatomy
pathology is the study of
disease
(path refers to disease)
(ie) pic
polyps, from tissue from the bowel

subdivisions of anatomy
embryology is the study of
developmental anatomy
formation and growth of an embryo

levels of organisation
what are the
levels of organisation
(6)
- chemical level
- cellular level
- tissue level
- organ level
- system level
- organimal level
levels of organisation

what does the suffix logy
the study of something
subdivisions of anatomy
anatomy can be divided into 2 further categories
- surface anatomy
- gross anatomy
subdivisions of anatomy
surface anatomy
looking at marking on the body to visualize
internal anatomy or structures are looking like
we can also use touch
as a method to visualise structures
that are internal to the body
*no disection involved in surface anatomy
subdivisions of anatomy
gross anatomy
*can be studied by 2 general approaches
systemic approch:
(systemic anatomy)
systemic approach :
concider the whole body systems
(ie) cardiovascular system, or the muscular system, skeletal system
*does involve dissection
subdivisions of anatomy
gross anatomy
*can be studied by 2 general approaches
regional approach:
(regional anatomy)
looking at a specific
region of the body
(rather than looking at at the various systems involved
this in contrast is)
restricted to a particular region in the body
(ie) the head, chest etc.
*does involve dissection
subdivisions of anatomy
other subdivisions
of the study of anatomy
(4)
(these specialised areas which focus in on certain aspects of the anatomy)
- histology
- cytology
- pathology
- embryology
<strong>1st </strong>level of organisation
chemical level
atoms
(C, H, O, N, P)
group together to
form a very important molecule called
DNA
<strong>1st</strong> level of organisation
chemical level
atoms that make up DNA
- C carbon
- H hydrogen
- O oxygen
- N nitrogen
- P phosophorus
between<strong> 1st chemical and 2nd cellular</strong> level
DNA is the molecule that carries our _ _ or _
genetic material
or
code
<strong>2nd</strong> level of organsation
Cellular level
The genetic material of DNA is stored in
a cellular structure known as
the nucleus
(which occurs within each cell of our body)
<strong>3rd</strong> level of organisation
tissue level
from the cellular level how are tissues formed?
cells group together
with similar structure and function
and
form tissues
<strong> 4th</strong> level of organisation
organ level
from the tissue level, how are organs formed?
tissues that are similar in
function and structure
group together to
form organs
<strong>5th</strong> level of organisation
system level
where various organs make up a particular
system
in the body
(ie. the digestive system)
<strong>6th</strong> level of organisation
(final, highest level of organisation)
organismal level
(human organism)
when all the various body systems are put together
11 organ systems

muscular system
- skeletal muscles
- tendons
11 organ systems

reproductive system
11 organ systems

lymphatic system
(green vessels are our lymphnodes
*important to assist our immunity)
11 organ systems

respiratory system
11 organ systems

integumentary system
11 organ systems

nervous system
(yellow lines are nerve tracks)
11 organ systems

skeletal system
(all the bones and joints)
11 organ systems

urinary system
(*important for a range of functions incl.
ph of our blood,
excreating urea
among other functions)
11 organ systems

digestive system
11 organ systems

endocrine system
(what helps control our hormones)
11 organ systems

cardiovascular system
(works closely with our respitory system to
deliver oxygen to all the tissues,
via cells within the blood,
also with our lymphatic system in fighting infections,
immunity and delivering immune cells to injured tissues, or tissue that have pathogens invading them)
