Extras Flashcards
What are the names of the body cavities?
Posterior which are completely encased by bone (cranial and vertebral cavities); and ventral which is lined with serous membranes (thoracic and abdominopelvic)
Visceral membrane:
inner layer that covers internal organs
Parietal membrane:
outer layer that lines the visceral membrane
Serous membrane:
liquid BETWEEN the visceral and parietal membrane so there is no unwanted friction
Anatomy:
study of structure
Histology:
study of tissues
Cytology:
study of cells
What are the 6 characteristics all organisms have in common?
organisation, metabolism, growth and development, responsiveness, regulation, and reproduction
Organization:
Atom, molecule, macromolecule, organelle, cell, tissue, organ, organ system, organism
Metabolism has 2 subsections. What are they and define them.
Anabolism: needs energy and it builds units. Catabolism: releases energy and breaks up larger units
What is food an example of?
Catabolism
What is our body using food an example of?
Anabolism
Reproduction has what 2 processes?
Mitosis and meiosis
Explain the difference between section and plane.
Section: cut to see internal anatomy; plane: imaginary flat surface that passes through the body
Transverse and midsagittal.
Transverse: horizontal cut that divides into inferior and superior; midsagittal: vertical midline cut
What is the difference between gross and microscopic anatomy?
Gross anatomy, you can see with your naked eye; microscopic anatomy, you need a microscope.
What are the 5 subsections of gross anatomy?
Systemic, regional, surface, comparative, and embryology
What are the 2 subsections of microscopic anatomy?
Cytology and histology
What is the study of systemic anatomy?
Studying the structure of a body system (cardiovascular, endocrine, etc.)
What is the study of regional anatomy?
Studying the structure of everything in a body’s region, regardless of which systems operate there (e.g. focusing on the axillary (armpit))
What is the study of surface anatomy?
Studying the structure of organs without seeing them openly (e.g. doctor has to know where to place their stethoscope; people who are CPR trained need to know the heart)
What is the study of comparative anatomy?
Comparing the structure of the same type/similar structure of 2 organisms (e.g. comparing a human’s humerus bone to a horse’s)
What is the study of embryology anatomy?
Studying structures from conception to birth
Coronal plane:
vertical cut that makes anterior and posterior parts
