Intro To Anatomy, Lab 1 Flashcards
What are Biological macromolecules?
Large organic molecules that are synthesized from smaller organic molecules.
Define Anatomy
The science of the body structure
what are the four main groups of macromolecules?
proteins
lipids
polysaccharides
nucleic acids
what is a cell?
a unit of living matter surrounded by a semi-permeable membrane and capable of reproduction.
what is lumen?
is the inside space (hollow space) within a tubular organ that connects to another organ.
what is a mucous membrane (mucosa)?
the lining layer of the tubular organs of the visceral body systems.
what do mucous membranes consist of?
epithelium
connective tissue
most of the time muscle tissue as well
What is the Normal Anatomic Position? aka NAP (demonstrate)
a standardized body position
what is an organ?
a body structure composed of at least two different tissues
what is an organelle?
they are the “organs” of a cell.
structural subcomponents of a cell, like the nucleus, endoplasmic reticulum, ribosomes, etc.
what is parenchyma?
the functional part of an organ
what is a plane?
a flat surface virtually passed through the body
define morphology
the structural design of the body
define serious membrane (serosa)
a thin transparent membrane formed of epithelium and connective tissue that lines the thoracic and abdominal cavities.
what is a sytem?
a group of organs that fulfills a specific function
how many system groups are in the human body?
12
5 visceral body systems
7 somatic body systems
what is taxonomy?
the science of classifying and naming plants and animals
what is a tissue?
a group of similar cells and their extracellular products
what the four basic tissues in the body?
muscle tissue
epithelial tissue
connective tissue
nervous tissue
Viscus (viscera=plural)
any organ that belongs to one of the visceral body systems.
- tubular in design
- mucous membrane lining
- one or more opening at the body surface
what subdivisions of anatomy will we be using in class?
gross anatomy
microscopic anatomy
systemic anatomy
define gross anatomy
body structure large enough to study without magnification
define microscopic anatomy
structures requiring magnification up to about 1000 times
define systemic anatomy
anatomy of the body divided into its organ systems
what is the best method of studying human anatomy?
dissection
what is the most common method and least invasive of studying anatomy?
palpation
what is auscultation and when would it be useful to use this method of studying anatomy?
evaluating structures by the sound that they make.
best use when studying; the heart, lungs, intestine, and in older people, joints.
what is percussion?
involves tapping on the body surface and listening to the noise that results
what is radiography?
its benefits and risks?
the science of using x-rays to produce radiographs
painless and noninvasive but have shown to be carcinogenic (cancer causing)
what is the best way to collect data that is the least invasive, that is painless and can produce a hard copy
MRI
but this is the most expensive form
The study of anatomy involves what 3 basic facets of information?
Name
Location
Function
What is the proper Anatomic nomenclature listed?
Nomina Anatomica
What are the 7 guidelines that are followed for naming an official nomenclature?
1-use a single or phrase
2-Latin on the official list
3-short and simple as possible (but retain instructional and discriptive)
4-easy to remember and above all, instructive and discriptive
5-structures that are closely related topographically should have similar names
6-differentiating objectives should generally be opposites
7-terms derived from proper names (people) should not be used
What does it me when body parts are ipsilateral to each other?
Their on the same side of the body
What is it when two body parts are contralateral to each other?
They are on opposite sides to each other
What are the five structural principles of morphology around which the body is organized?
1- Tubulation 2- Stratification 3- Zygomorphism 4- Metamerism 5- Cavitation
Describe the structural principle of tubulation
Hollowness that continues from one organ to another
Define the structural principle of stratification
Structural layering
Define the structural principle of zygomorphism
Refers to bilateral symmetry
Define the structural principle of metamerism
Linear series of similar structures (ribs, vertebrae)
Define the structural principle of cavitation
Implies hollowness. Large spaces within various body regions.
