How does the transverse plane divide the body?
The transverse plane (axial or X-Z plane) divides the body into superior and inferior (head and tail) portions. It is typically a horizontal plane through the center of the body and is parallel to the ground.
What is a transverse section cut?
Cross, or transverse, section: a cut that is perpendicular to the main plane of the organ or specimen. Tangential section: a section that only grazes the surface of a spherical structure. Our body parts are not square.
What is a transverse cut?
Transverse plane—A horizontal cut that separates the top from the bottom of the specimen. Also known as a cross-sectional plane.
Is transverse the same as cross section?
Sections through or parallel to either the sagittal or coronal (also called frontal) plane are longitudinal. A transverse section is perpendicular the anterior-posterior axis and is also called a cross section .
Is longitudinal up and down?
We can make a horizontal transverse wave by moving the slinky vertically up and down. In a longitudinal wave the particles are displaced parallel to the direction the wave travels. An example of longitudinal waves is compressions moving along a slinky.
What is a longitudinal direction?
That direction parallel to the direction of maximum elongation in a worked material. See also normal direction and transverse direction.
What is a longitudinal dimension?
adj. 1 of or relating to longitude or length. 2 placed or extended lengthways.
What is a longitudinal study design?
In a longitudinal study, researchers repeatedly examine the same individuals to detect any changes that might occur over a period of time. Longitudinal studies are a type of correlational research in which researchers observe and collect data on a number of variables without trying to influence those variables.
Is a longitudinal study the same as a cohort study?
Longitudinal studies allow social scientists to distinguish short from long-term phenomena, such as poverty. However, not all longitudinal studies are cohort studies, as longitudinal studies can instead include a group of people who do not share a common event.
What is the greatest drawback of the longitudinal method?
Longitudinal studies require enormous amounts of time and are often quite expensive. Because of this, these studies often have only a small group of subjects, which makes it difficult to apply the results to a larger population.
What are the strengths and weaknesses of cross-sectional study?
4. Strengths and weaknesses of cross-sectional studies
- Relatively quick and easy to conduct (no long periods of follow-up).
- Data on all variables is only collected once.
- Able to measure prevalence for all factors under investigation.
- Multiple outcomes and exposures can be studied.
