Introducrion To Anatomy (Questions) Flashcards
What is anatomy?
Anatomy is the study of internal and external body structures and the relationships between them.
What is an example of how anatomy studies relationships between structures?
An example is the relationship between bones and muscles.
What are the two main subdivisions of anatomy?
The two main subdivisions are microanatomy and gross anatomy.
What is microanatomy, and what are its two subfields?
Microanatomy is the study of structures that require a microscope. Its subfields are cytology (study of individual cell structures) and histology (study of tissues)
What is gross anatomy?
Gross anatomy is the study of structures visible to the naked eye, such as bones, the heart, and the stomach.
What are some examples of structures studied in gross anatomy?
Examples include body cavities like cranial, thoracic, and abdominopelvic cavities.
What is the simplest level of organization in the body?
The simplest level of organization is the chemical level, which involves atoms and molecules.
What forms when atoms join together?
When atoms join together, they form molecules, such as water (H₂O).
What is the cellular level of organization?
The cellular level involves organelles forming cells, which are the basic units of structure and function in the body.
Give an example of different types of cells with varying functions.
Examples include erythrocytes (red blood cells), neurons, and muscle cells.
What defines the tissue level of organization?
The tissue level consists of groups of structurally similar cells with a common function.
What are the four major types of tissues in the body?
The four major tissue types are epithelial, connective, muscle, and nervous tissues.
What is the organ level of organization?
The organ level involves two or more tissues working together for a common function, such as the stomach’s role in digestion.
What is the organ system level?
The organ system level consists of several related organs working together to accomplish a common purpose, like the respiratory system.
What is an example of an organ system, and what is its function?
The respiratory system is an example, and its function is respiration.
