Chapter 1 Anatomy And Physiology Meaning Flashcards
What is anatomy
The scientific study of the body’s structure
Gross Anatomy
The study of larger structures of the body, those visible without magnification.
Macro=Large
Also referred to macroscopic anatomy
Microscopic Anatomy
Is the study of structures that can be observed only with the use of a microscope
Ex: cytology (study of cells), histology ( study of tissues)
What is Regional anatomy, and what does it help us understand
Definition- The study of the interrelationships of all the structures in a specific body region, like the abdomen.
- Helps us understand interrelationships of body structures, like how muscles, nerves, blood vessels, and other structures work together to serve a particular body region.
What is systemic anatomy?
The study of the structures that make up a body system that a group of structure work together to perform a unique body function
Ex: a systemic anatomical study of the muscular system would consider all of the skeletal muscles of the body.
What is physiology
The study of the chemistry and psychics of the structures of the body and the ways they work together to support the functions of life
Most of the study centers on the body tendency toward homeostasis
What is homeostasis
The state of steady internal conditions maintained by the living things.
What is a cell?
The smallest independently functioning unit of a living organism.
What is a organelle
A human cell that typically consists of flexible membranes that enclose cytoplasm, a water based cellular fluid together with a variety of tiny functioning units
Cells perform all functions of life.
What is a tissue
A group of may similar cells ( though sometimes composed of a few related types) that work together to perform a specifc function
What is an organ?
Organ is an anatomically distinct structure of the body composed of two or more tissue types.
Every organ performs major functions or meet physiological functions.
What is an organ system
A group of organs that work together to perform major functions or meet physiological needs of the body
