What is the anatomical term?
Anatomical terms are made up of roots, prefixes, and suffixes. The root of a term often refers to an organ, tissue, or condition, whereas the prefix or suffix often describes the root. For example, in the disorder hypertension, the prefix “hyper-” means “high” or “over,” and the root word “tension” refers to pressure, so the ...
What is the anatomical term refers to the groin?
The groin is a part of human anatomy, found high along the inner thighs where the leg muscles join the lower abdomen and form creases in the flesh as the legs meet with the torso. Muscles in the groin are responsible for parting and closing the thighs as well as for holding the thighs together.
What is the importance of anatomical terminologies?
It is important to use anatomical terminology when describing body parts to centralize communication about the body. This allows scientists and medical professionals to accurately describe anatomical locations, preventing both confusion and misunderstanding.

What are the 7 anatomical parts?
The entire human body is divided into regions, an approach called regional anatomy. Each main area (head, neck, thorax, abdomen, upper, and lower extremities) are divided into several smaller regions that aid compartmentalization.
What are the 3 types of anatomy?
These are surface anatomy, the study of external anatomical forms and markings; regional anatomy, which focuses on a certain region of the body (both internal and external); and systemic anatomy, which focuses on a given organ system.
Why is it important to be familiar with anatomical terminology?
Understanding terminology ensures doctors and technicians have a shared method of communicating, which helps to avoid confusion when pinpointing structures and describing locations of lesions. Knowing your directional terms makes things clear and saves time!
Why is it important to use anatomical terminology with children?
“It helps children develop a healthy, more positive body image, instead of using nicknames that their genitals are something shameful or bad,” she said. “It also gives children the correct language for understanding their bodies and asking questions about sexual development.”
What language does anatomical terminology come from?
Anatomical terms derive from ancient Greek and Latin words. Because these languages are no longer used in everyday conversation, the meaning of their words does not change. Anatomical terms are made up of roots, prefixes, and suffixes.
How many terms are in anatomy?
There are around eight thousand anatomical terms to learn in order to understand the macroscopic and microscopic structures that comprise the human body.
What are the 4 branches of anatomy?
Gross anatomy is subdivided into surface anatomy (the external body), regional anatomy (specific regions of the body), and systemic anatomy (specific organ systems). Microscopic anatomy is subdivided into cytology (the study of cells) and histology (the study of tissues).
What are the 4 main anatomical position?
Anatomically, there are four main positions: supine, prone, right lateral recumbent, and left lateral recumbent. It is important to note that each position has its medical implications.
What are some examples of an anatomical study?
An example of anatomical study would be learning about the different bones in the body and their location. Anatomy can often be confused with physiology, which focuses more on the function of organs rather than their location in the body.
What are the 4 main anatomical positions?

Why is it important to know the terminology used to describe location and relationships within the nervous system?
Familiarity with the terminology used to describe location and relationships within the nervous system is critical as we move forward into examining brain systems.
What are the three anatomical planes?
Figure 16.2. Three anatomical planes are used to divide the nervous system to be able to view internal regions and structures. The frontal or coronal plane is a vertical plane that runs parallel to the eyes or ears and will divide the body into front and back regions. The sagittal plane is a vertical plane that runs perpendicular to the eyes or ears and will divide the body into left and right regions. The horizontal plane runs parallel to the ground and will divide the body into top and bottom regions. ‘Anatomical Planes’ by Casey Henley is licensed under a Creative Commons Attribution Non-Commercial Share-Alike (CC BY-NC-SA) 4.0 International License.
What are the two main parts of the nervous system?
The nervous system is divided into two primary components. The central nervous system (CNS) is comprised of the brain and the spinal cord . The peripheral nervous system (PNS) is comprised of the cranial and spinal nerves. When information flow is described in the nervous system, it can either be afferent communication, meaning it is moving from the periphery to the brain, or efferent communication, meaning it is moving from the brain to the periphery.

Why do anatomists use terminology?
However, the purpose of this language is not to confuse, but rather to increase precision and reduce medical errors.
How many regions are there in the abdominal cavity?
To promote clear communication, for instance about the location of a patient’s abdominal pain or a suspicious mass, health care providers typically divide up the cavity into either nine regions or four quadrants ( Figure 1.16 ).
Which body compartments contain the most organs?
The dorsal (posterior) cavity and the ventral (anterior) cavity are the largest body compartments ( Figure 1.15 ). These cavities contain and protect delicate internal organs, and the ventral cavity allows for significant changes in the size and shape of the organs as they perform their functions.
What does anterior mean in anatomy?
Anterior (or ventral) Describes the front or direction toward the front of the body. The toes are anterior to the foot.
What is the upper arm called?
Notice that the term “brachium” or “arm” is reserved for the “upper arm” and “antebrachium” or “forearm” is used rather than “lower arm.”. Similarly, “femur” or “thigh” is correct, and “leg” or “crus” is reserved for the portion of the lower limb between the knee and the ankle.
How many planes are there in anatomy?
A plane is an imaginary two-dimensional surface that passes through the body. There are three planes commonly referred to in anatomy and medicine, as illustrated in Figure 1.14.
When describing anatomical terms of location specific terms are used to avoid confusion.?
If there was an imaginary midline drawn on the body then anything closer towards the mid line is termed media l and anything away from the midline either left or right is termed lateral e.g. the little finger lies medially when compared to the index finger. Likewise if something is further to the front of the body it is anterior and if further back it is posterior.
What is the term for the position of the body?
Anatomical Terminology. Before defining any specific terms, the body must be given a universal position which is known as the anatomical position. This is a universal way to position the human body so it acts as a reference point for describing anatomy.
What are the three planes of anatomy?
This slice however can be done at different angles with respect to the body. The three most commonly used planes are: sagittal, coronal and transverse. The sagittal plane divides the body into left and right regions. The coronal plane separates the front (anterior) and back (posterior) halves of the body. The transverse plane demarcates the upper parts of the body from the lower e.g. it divides the torso + upper limbs from the legs + hips.
Which plane divides the upper body from the lower body?
The transverse plane demarcates the upper parts of the body from the lower e.g. it divides the torso + upper limbs from the legs + hips. Anatomical terms of movement are used to describe ways in which the body moves due to the action of certain muscles.
Is something posterior or anterior?
Likewise if something is further to the front of the body it is anterior and if further back it is posterior. In embryology, there are other terms used which is in further detail in the article on anatomical terminology.
What is human anatomy?
Human anatomy is the study of the structure of the human body. Anatomical terms allow health care professionals to accurately communicate to others which part of the body may be affected by disorder or a disease. Terms are defined in reference to a theoretical person who is standing in what is called anatomical position ...
Why is it important to communicate anatomical terms?
For example, suppose a doctor was trying to describe an area of the body to another physician on a patient who is lying face down? Descriptions would be based on anatomical position to make things simpler and to avoid any confusion.
Where is the ventral cavity?
The ventral cavity is on the front of the trunk. The diaphragm (the main muscle of breathing) divides the ventral cavity into two simple subcavities: thoracic and abdominopelvic cavities.

Superficial and Deep. Superficial means toward the body surface, deep means away from the body surface. E.g. Skin is superficial to a person’s organs. A person’s organs are deep to skin.
What is the difference between lateral and medial?
Medial and Lateral – Medial means toward the midline of the body, lateral means away from the midline. Proximal and Distal – Proximal means closest to the point of origin or trunk of the body, distal means farthest away. These terms are often used to describe the arms and legs.
What does superior mean in anatomy?
Superior and Inferior – Superior means above, inferior means below. E.g. The elbow is superior (above) to the hand. The foot is inferior (below) to the knee. Anterior and Posterior – Anterior means toward the front (chest side) of the body, posterior means toward the back.
Where is the plantar reference?
Plantar references the bottom of the foot.
Why do we use anatomical terminology?
For example, is a scar “above the wrist” located on the forearm two or three inches away from the hand? Or is it at the base of the hand? Is it on the palm-side or back-side? By using precise anatomical terminology, we eliminate ambiguity. Anatomical terms derive from ancient Greek and Latin words. Because these languages are no longer used in everyday conversation, the meaning of their words does not change.
What is the root of anatomical terms?
Anatomical terms are made up of roots, prefixes, and suffixes. The root of a term often refers to an organ, tissue, or condition, whereas the prefix or suffix often describes the root. For example, in the disorder hypertension, the prefix “hyper-” means “high” or “over,” and the root word “tension” refers to pressure, so the word “hypertension” refers to abnormally high blood pressure.
How many regions are there in the abdominal cavity?
To promote clear communication, for instance about the location of a patient’s abdominal pain or a suspicious mass, health care providers typically divide up the cavity into either nine regions or four quadrants ( Figure 5 ).
How do anatomists view the body?
Just as maps are normally oriented with north at the top, the standard body “map,” or anatomical position, is that of the body standing upright, with the feet at shoulder width and parallel, toes forward. The upper limbs are held out to each side, and the palms of the hands face forward as illustrated in Figure 1. Using this standard position reduces confusion. It does not matter how the body being described is oriented, the terms are used as if it is in anatomical position. For example, a scar in the “anterior (front) carpal (wrist) region” would be present on the palm side of the wrist. The term “anterior” would be used even if the hand were palm down on a table.
What does anterior mean in anatomy?
Anterior (or ventral) Describes the front or direction toward the front of the body. The toes are anterior to the foot.
What is the upper arm called?
Notice that the term “brachium” or “arm” is reserved for the “upper arm” and “antebrachium” or “forearm” is used rather than “lower arm.”. Similarly, “femur” or “thigh” is correct, and “leg” or “crus” is reserved for the portion of the lower limb between the knee and the ankle.

A plane is an imaginary two-dimensional surface that passes through the body. There are three planes commonly referred to in anatomy and medicine, as illustrated in Figure 3.
How to study anatomy?
Understanding anatomical directional terms and body planes will make it easier to study anatomy. It will help you to be able to visualize positional and spatial locations of structures and navigate directionally from one area to another. Another strategy that can be employed to help you visualize anatomical structures and their positions is to use study aids such as anatomy coloring books and flashcards. It may seem a bit juvenile, but coloring books and review cards actually help you to visually comprehend the information.
What are some examples of anatomical structures?
Some examples include the anterior and posterior pituitary, superior and inferior venae cavae, the median cerebral artery, and the axial skeleton.
How to describe anatomical planes?
Imagine a person standing in an upright position. Now imagine dissecting this person with imaginary vertical and horizontal planes. This is the best way to describe anatomical planes. Anatomical planes can be used to describe any body part or an entire body. (View a detailed body plane image.)
What is anatomical directional?
Anatomical directional terms are like the directions on a compass rose of a map. Like the directions, North, South, East and West, they can be used to describe the locations of structures in relation to other structures or locations in the body. This is particularly useful when studying anatomy as it provides a common method ...
