Introduction
Entering the world of anatomy as a chiropractic student might feel like being dropped into a foreign country where you don’t speak the language. Medical terminology, which is derived largely from Latin and Greek, may initially seem daunting. However, by breaking down the words into their components – prefixes, root words, and suffixes – we can begin to decipher the meaning behind the complex anatomical terms. This post will introduce you to the concept of prefixes in anatomical language and how understanding them can ease your anatomy learning journey.
Prefixes in Anatomy
In the realm of medical terminology, prefixes are attached at the beginning of words to modify or qualify their meaning. For example, ‘sub-‘ denotes something beneath or under, while ‘super-‘ signifies something above or excessive.
Anatomical prefixes often indicate position, number, timing, or direction. Consider the prefix ‘infra-‘, for instance. This term originates from Latin, where it means below or beneath. Therefore, in anatomy, anything referred to as ‘infra-‘ is positioned underneath something else. An example is the ‘infraspinatus’ muscle, which is situated below the spine of the scapula.
Another common prefix is ‘bi-‘, which is used to denote the number two. Hence, a ‘bicuspid’ tooth has two cusps.
Common Prefixes in Anatomy
To help you master anatomical prefixes, here’s a list of some of the most commonly used ones:
‘A-‘ or ‘An-‘: Without or lack of. Example: Avascular (Without blood vessels)
‘Ab-‘: Away from. Example: Abduction (Movement away from the midline)
‘Ad-‘: Towards or near. Example: Adduction (Movement towards the midline)
‘Anti-‘: Against. Example: Antiperistalsis (Reverse of the normal direction of peristalsis)
‘Bi-‘: Two. Example: Bicuspid (Having two cusps)
‘Brady-‘: Slow. Example: Bradycardia (Slow heart rate)
‘Dys-‘: Bad, difficult. Example: Dyspnea (Difficulty breathing)
‘Epi-‘: Above, upon. Example: Epidermis (Outer layer of the skin)
‘Hyper-‘: Over, above normal. Example: Hypertension (High blood pressure)
‘Hypo-‘: Under, less than normal. Example: Hypotension (Low blood pressure)
‘Infra-‘: Below. Example: Infraspinatus (Below the spine of the scapula)
‘Inter-‘: Between. Example: Intercostal (Between the ribs)
‘Intra-‘: Within. Example: Intracellular (Within the cells)
‘Sub-‘: Under, beneath. Example: Subcutaneous (Under the skin)
‘Super-‘: Above, excessive. Example: Superficial (Near the surface)
‘Tachy-‘: Fast. Example: Tachycardia (Fast heart rate)
‘Trans-‘: Across. Example: Transdermal (Through the skin)
Conclusion
Understanding the prefixes used in anatomical terminology can be a significant first step in unravelling the complex language of anatomy. As you delve deeper into your chiropractic studies, this knowledge will become an invaluable tool, helping you to understand not only the names of body parts and their relationships but also their functions and clinical significance.
