Looking to learn more about the human body? Start with learning about all of its parts! In this article, we will provide a comprehensive list of anatomical terms. This is a great place to start if you are looking to bone up on your knowledge of the human body. We will define each term and provide an image for reference. So, let’s get started!
Terms And Terminology For Anatomical Terms
- Anterior – front
- Posterior – back
- Superior – above
- Inferior – below
- Dorsal – toward the back (spine) side
- Ventral – toward the stomach/chest side
- Lateral – to the side
- Medial – in the middle
- Proximal – nearer to the centre of the body or point of attachment
- Distal- further from the centre of the body or point of attachment
Anatomical Directional Terms
These terms are used to describe the relative positions of various structures within the human body. These terms can be broken down into three main categories: planes and axes, regional terms, and surface anatomy terms. Let’s take a closer look at each of these categories.
Planes and Axes
A plane is a two-dimensional surface that passes through the body. There are three main planes that we use to describe the human body: the sagittal, frontal, and transverse planes.
The sagittal plane runs vertically through the midline of the body, dividing it into right and left halves. The frontal or coronal plane also runs vertically through the body, but it divides the front from the back. The transverse plane (also called a cross-section) divides the top from the bottom.
Axes are imaginary lines that pass through the body in a specific direction. There are three main axes that we use to describe anatomical position:
The vertical axis (also called the longitudinal axis) runs from top to bottom.
The horizontal axis (also called the transverse or crosswise axis) runs from side to side.
The anteroposterior or craniocaudal axis runs from front to back.
Regional Terms
Regional terms are used to describe specific areas of the body. For example, the axilla is the area under the arm where the arm meets the body. Similarly, the perineum is the area between the legs that includes the genitals and anus.
Here is a list of some common regional terms:
- Abdomen – stomach area
- Arms – upper limbs
- Back – posterior trunk
- Breasts – mammary glands
- Chest – thorax
- Ears – auricles
- Eyes – orbs
- Face – visage
- Fingers – digits
- Foot – pedal extremity
- Genitals – reproductive organs/external genitalia
- Hair – pili
- Hand – manus
- Head – cephalon or cranium
- Heart – cardiac muscle tissue and associated structures
- Kidneys- renal system organs
- Legs- lower limbs
- Lips- labia
- Mouth- oral cavity
- Nose- nares or nostrils
Surface Anatomy Terms
Surface anatomy is the study of the external features of the body. This includes things like hair, nails, and the skin. It also includes external features of the anatomical regions, such as the eyes, ears, and mouth.
Significance Of Anatomical Terms
Anatomical terms are important for precision and clarity when describing the location of structures in the body. This is especially important when communicating with other healthcare professionals. In addition, a strong understanding of anatomical terminology is essential for students of medicine, nursing, and other health sciences.
Conclusion
This list of anatomical terms is by no means exhaustive, but it should give you a good starting point in understanding the basic structure and function of the human body. With a little bit of practice, you’ll be able to use these terms like a pro!
