Flashcard Content Overview

It's Friday night, and you decide to turn on your favorite medical drama. Just as you settle into your seat, you hear the following dialogue:

'The patient is presenting with epidermal and dermal burns on the lateral sides of the arms. In addition, there is significant damage to the tissue found on the anterior portion of the left kidney and on the inferior portion of the contralateral lung.'

Though it might sound like gibberish, medical professionals use special terminology to communicate the body's basic organization. This flashcard set will help you start to make sense of the study of anatomy, which begins with understanding how multicellular organisms are organized and how to locate parts in and on their bodies.

Identify the Plane of the Body Labelled 'B'
Coronal plane
Coronal Plane

The plane that separates the anterior and posterior regions of the body

Also known as the frontal plane because it separates the front from the back

Transverse Plane

The plane that separates the superior and inferior regions of the body

Also known as the horizontal plane because it runs horizontal to the ground

Identify the Plane of the Body Labelled 'C'
Transverse plane
Ispilateral
An anatomical direction that refers to something on the same side of the midline of the body
Superior
An anatomical direction that refers to anything up towards the head or above something on the body
Organ System

A group of tissues and organs in an organism working together to perform a specific function

Example: the circulatory system, which includes the heart, blood, and blood vessels

Epidermis

Layers of skin cells that make up the outermost layer of the skin

Also contains specialized cells, including melanocytes, Merkel cells, and keratinocytes

Subcutis

Also known as the subcutaneous or hypodermis layer

The innermost layer of the skin, located beneath the dermis

Contains blood vessels, nerves, and connective tissue such as adipose tissue

Adipose Tissue
A type of connective tissue commonly referred to as body fat
