To successfully study anatomy and physiology, you'll want to understand all the Latin and Greek roots, prefixes and suffixes. Also, make sure to get a good foundational knowledge of anatomic cavities, anatomic positions (standard positions when looking at an anatomical drawing), and anatomic planes.Latin and Greek in anatomy and physiologyScience, especially medicine, is permeated with Latin and Greek terms.

Atoms tend to arrange themselves in the most stable patterns possible, which means that they have a tendency to complete or fill their outermost electron orbits. They join with other atoms to do just that. The force that holds atoms together in collections known as molecules is referred to as a chemical bond. There are two main types and some secondary types of chemical bonds:Ionic bondIonic bonding involves a transfer of an electron, so one atom gains an electron while one atom loses an electron.

All matter — be it solid, liquid, or gas — is composed of atoms. An atom is the smallest unit of matter capable of retaining the identity of an element during a chemical reaction. An element is a substance that can’t be broken down into simpler substances by normal chemical reactions. There are 98 naturally occurring elements in nature and 20 (at last count) artificially created elements for a total of 118 known elements.

Science, especially medicine, is permeated with Latin and Greek terms. Latin names are used for every part of the body; and since the Greeks are the founders of modern medicine, Greek terms are common in medical terminology, as well. Latin and Greek roots This table represents some common Latin and Greek root

Molecules that pass muster with the cell membrane enter the cytoplasm, a mixture of macromolecules (such as proteins and RNA), small organic molecules (such as glucose), ions, and water. Because of the various materials in the cytoplasm, it’s a colloid, or mixture of phases, that alternates from a sol (a liquid colloid with solid suspended in it) to a gel (a colloid in which the dispersed phase combines with the medium to form a semisolid material).

It may look like cells are living out their useful lives simply doing whatever specialized jobs they do best, but in truth mitosis is a continuous process. When the cell isn’t actively splitting itself in two, it’s actively preparing to do so. DNA and centrioles (arrays of microtubules) are being replicated, and the cell is bulking up on cytoplasm to make sure there’s enough for both daughter cells.

The hard part of the fingernails and toenails contains a tough protein called keratin. Human nails (which actually are vestigial claws) have three parts: a root bed at the nail base, a body that’s attached to the fingertip, and a free edge that grows beyond the end of the finger or toe. Heavily cornified tissue forms the nails from modified strata corneum and lucidum.

Whenever you see an anatomical drawing, like the one below, you’re looking at the anatomic position. This standard position (standing straight, looking forward, arms at your side, and facing forward) keeps everyone on the same page when you’re talking anatomy and physiology. Keep this list handy of anatomic d

When you’re talking anatomy and physiology, the body is divided into sections, usually three planes. Separating the body into sections, or cuts, let’s you know which body half is being explained. The anatomic planes are: Frontal or coronal: Divides the body into front (anterior) and back (posterior) Sagit

Your body’s cavities are basically the “holes” that would be left (besides bones and tissues forming the space) if you removed your internal organs. Your body has two main cavities; the dorsal and ventral. Ventral cavity: Extends from just under the chin to the pelvic area, encompassing the thoracic cavity, d
