chapter 1 Flashcards
What is anatomy ?
study of external and internal structures and physical relationship between body parts
What is physiology ?
study of the function of an organism
Homeostasis ?
maintenance of appropriate conditions within the body
• requires both proper structure and function
Pathology
study of disease
How to diagnose someone that has a disease ?
• diagnosis – decision about the nature of an illness – relies on understanding of normal structure and function of human body
Gross Anatomy
examination of structures visible with the eye
Surface Anatomy
external form of the body and relation to deeper structures determined through visualization (looking) and palpation (feeling)
Surface anatomy is part of ….
GROSS anatomy
Developmental anatomy
structural changes from conception to physical maturity
Embryology?
and it is part of ….
= changes in structure from(pregnancy)
developmental anatomy
Microscopic Anatomy ?
examples ?
requires use of microscope
ex: Cytology - examines internal structures of cells
Histology : examines tissues – groups of specialized cells working together to perform specific functions
Non-invasive imaging are the use of ….
examples ?
specialized equipment to view internal structure without the need of surgical intervention
1) X-RAY
2) Ultrasound
3) Computed tomography
4) Digital subtraction Angiography
5) Magnetic resonance Imaging
X -rays ?
• produces a radiograph
– bones and radiopaque dyes absorb the rays and creating areas that appear white.
- Only produce 2-D images of the body
Ultrasound
• produce a sonogram or echogram- sound waves that bounce off structures and echos picked up and analyzed by computer
o no adverse effects - useful for examining fetal development
Computed Tomography (CT)
scans serial x-rays in 360-degree arc and computer constructs image
