Chapter 1 Flashcards
Why is it important for a CT technician to understand brain anatomy?
To accurately interpret the sectional images and ensure correct positioning of the patient
What is the role of the CT technician in relation to the sectional images produced?
The technician must be able to interpret the sectional images produced of the brain.
For a cranial CT scan, what must the CT technician understand?
Relevant brain anatomy and the ability to interpret sectional images of the brain.
What is an important aspect of communication during an imaging procedure?
communicate clearly with a patient
What are the key imaging techniques used by a medical imaging technologist?
Ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI)
Anatomy
the study of structure and form
physiology
the study of function and body parts
the word anatomy is derived from??
anatome
anatome means
cut apart or dissect
anatomists are scientists who
theudy the form and structure of organisms
physiologists examine
how organs and body systems may be altered via medication or disease
the scientific method is method by which scientists
-examine natural events
-develop a hypothesis
-experiment to tes the hypothesis
-determine if the data supports the hypothesis.
early psychologists used the scientific method to
how blood cirulates throguh the body
how do we use the scientific method today
to understand how the brain stores memories or explain how cancer spreads
microscopic anaotmy examines
structures that cannot be seen by an unaided eye
people normally study microscopic anatomy by slicing a thin slices of body structures
by slicing thin slices of body structures, preparing specific cells,
microscopic anatomy has 2 main divisions
cytology and histology
cytology is
the study of body cells and their internal structures
histology
the study of body tissues
gross anatomy is another major field it investigates
the structure and relationships of body parts that are visible to the unided eye
gross anatomy is also called
macroscopic anatomy
gross anatomy studies things like
intrstines, stomach, brain, heart, and kidneys
gross anatomy is often done by _______ speciments
dissecting
systemic anatomy
studies anatomy of each functional body system
if someone who studies systemic anatomy wanted to study the urine what would they study
kidney. because thats where urine is made, and urine transport organs
most undergraduate anatomy and physiology classes use this approach
systemic
what are the urine transport organs
ureters and urethra
regional anatomy
examines all of the structures in a particular region.
axillary region
arm pit
surface anatomy
focuses on both superficial and internal body structures that relate to skin coivering them.
health care provders use surface features to identify and locate
important landmarks such as pulse locations or the proper body region on which to perform cpr.
comparative anatomy
examines the similarities and differences in the anatomy of different species.
comparative anatomy fight for example study
limbs of humans, dogs, chimps, and cats.
embryology
is the discipline concerned with developmental changes occurring from conception to birth
what branches of anatomy focus on the diagnoses of medical conditions or the advancement of basic scientific research
pathologic anatomy, radiographic anatomy
pathologic anatomy
examines all anatomic changes resulting from diseas
radiographic anatomy
investigates relkationship among internal structures tht may be visualized by soecific scanning procedures
what scans does radiographic anatomy do
x-ray, mri, ct scan, ultrasounds
MRI
magnetic resonance imaging
ct scan
computed tomagraphy
cardiovascular physiology focusus on
the functioning of the heart, blood vessels, and blood
neurophysiology examines
how nerve impulses are propagated throughout the nervous system
respitorty physiology studies
how respitory gases are transfered by gas exchange between lungs and the blood vessels.
reproductive physiology explores
how the regulation of reproductive hormones can drive the reproductive cycle and influence sex cell production and maturation.
pathophysiology investigastes
the relationship between the functioning of an organ system and disease or injury to that organ.
organization
all organisms exhibit a complex order
metabolism
sum of all chemical reactions that occur in the body
anabolism
small molecules form to make larger molecules
catabolism
large molecules are broken down into smaller ones
growth and development
during a organisms lifetime an organism may assimilate materials from their environment to increase in size
responsiveness
an organism must be able to adjust bodily function in respnse to environmental change
reproduction
all cells produce cells for growth, repair, and maintenance. somatic cells divide by a process called mitosis.
somatic cells divide by
mitosis
gamates or ____ divide by
sex cells, meiosis
all organisms must exchange_______(3) with their environments
nutrients, waste, and gases
muscular system
produces body movement, generates heat when muscles contract
nervous system
system that responds to stimuli. controls some muscles and glands. also responsible for intelligence, memory, and consciousness
integumentary systems
provides protection, prevents water loss, synthesizes vitamin D, releases secretion, houses sensory receptors
skeletal system
provides support, and protection. site of hematopoises. stores calcium. provides sites for ligament and muscle attachments
supine
laying down
