BIOL 2220- Exam 1 with completesolutions
Anatomy - Answers -The structure of parts and their composition as well as how they
work together.
Gross Anatomy - Answers -Study of the big stuff that you can see from the outside
(macroscopic).
Regional Anatomy - Answers -Study by region of the body.
Ex. Neck anatomy; Leg anatomy
Systemic Anatomy - Answers -Study of certain body systems.
Ex. Reproductive; Cardiovascular
Surface Anatomy - Answers -Study of what's on the surface of the body.
Ex. Markings
Important in forensics
Microscopic Anatomy - Answers -Studying what you can't see without a microscope.
Ex. Cytology--> Study of cells (pap smear)
Ex. Histology--> Study of tissues (connective, muscular, epithelial)
Developmental Anatomy - Answers -Study of structural changes from fertilization to
adulthood.
Ex. Embryology--> Study of embryo progression until birth
Pathological Anatomy - Answers -Study of changes in structure to disease.
- There's overlap here, because there can be changes in any structure.
Radiographic Anatomy - Answers -Study of structures using x-ray or other types of
biotechnology.
X-Ray - Answers -Puts light energy (gamma radiation) through the body, and the film on
the backside gets exposed and the body absorbs the light so we have a negative.
First of radioactive anatomy.
We can only see the hard structures!
CT Scan - Answers -"Computerized Topography"
Light energy is passed through the body, and the signals are sent to a computer where
an image is then created.
, Mostly see hard structures.
Basically an X-ray but with overlap (can take pictures at different levels.)
Xenon CT - Answers -Xenon gas is inhaled by the patient and the most active tissues
are the brightest colors on the scan.
Ex. Dark space means that a stroke has occurred.
DSR Scan - Answers -"Dynamic Spacial Reconstruction"
It's like a CT, but it's 3-D.
We're still using light energy for a computerized image.
DSA Scan - Answers -"Digital Subtraction Angiography"
You're taking a CT scan, but then adding in contrast dye and taking a second picture to
show the blood vessels/arteries.
Can see if anything is leaking.
PET Scan - Answers -"Positron Emission Tomography"
A radioactive substance is injected into the body and it will accumulate in the active
tissue.
Very good for cancer identification.
Ultrasound - Answers -Sound waves are projected on the body, are referred to the
receiver, and we can see the echos.
NOW we can see some soft tissue!
Developed in the 70's to look at babies in the womb.
MRI - Answers -"Magnetic Resonance Imaging"
Creates a magnetic field by using magnets around the patient.
The charged ions line up in the body as the MF is around it, and we get a computerized
image.
Should fill the empty spaces as bright white.
MRS Scan - Answers -"Magnetic Resonance Spectroscopy"
Detects the alignment and gives us a picture and shows us where different ions are
present.
Determines chemical makeup of the soft tissue that it's analyzing.
M2A - Answers -A pill that is swallowed with a camera inside that shoots pictures being
sent to a computer.
Much less invasive, but once it hits the stomach it's destroyed and passed.
Physiology - Answers -The study of the functions of body parts.
Chemical and physical processes.
The Big Integration - Answers -Structure can dictate function, and function can dictate
structure.
