Study of Human Anatomy Flashcards
gross anatomical level
Examination of structures visible to the naked eye (bones, muscles, blood vessels)
histological level
The microscopic level of analysis (cells and the tissues they make up)
regional anatomy
When structures in a single region are examined as a group
systematic anatomy
When the focus is on all organs and structures that share a common function
surface anatomy
The study of the shapes and landmarks on the surface of the body that reveal underlying structures.
embryology
branch of anatomy that focuses on the formation and development of structures before birth
pathological anatomy
the study of the structural changes caused by disease
X-rays
Visualize bones, and locating abnormally dense structures
May include a contrast medium (barium)
Negative effects of traditional x-rays are that they can be blurry and not 3-D
Computer Tomography (CT)
Soft structures are better seen in CT scans vs typical radiographs because of computer enhancement techniques
The computers compile images very quickly
Sonography
Way of examining the internal body with pulses of high-frequency (ultrasonic) sound ways that echo off different tissues.
The echos are examined and organ outlines are generated
Angiography
Way of getting images of cardiac/other vessels by injecting a contrast medium in the blood stream and then using another method to view
Positron Emission Tomography (PET)
Detects radioactive isotopes, and can detect regions of cellular activity
Used heavily in oncology to assess tumor areas and their growth rates and distribution
Magnetic Resonance Imaging (MRI)
Provides high contrast images of soft tissues
Detects hydrogen levels and uses this to draw distinctions between tissues based on different water contents
