Chapter 12-the Nervous System Suffixes and Terms related to the Nervous System Corinne E. Preis BIO 120
While there are many word roots, prefixes and suffixes concerning the functioning of the nervous system, I have chosen to define 2 and provide you with some examples of theses suffixes in regards to the nervous system. - Plegia and -Esthesia
- esthesia This suffix probably looks familiar as we encounter this combined with a number of root words in the medical field.
esthesia is a term that is Greek in origin.
It’s meaning is the capacity for perception, sensitivity or feeling. It can also mean any disorder of the nervous system that affects perception or sensitivity.
The suffix- esthesia is combined with numerous prefixes and word roots to make a variety of word that describe conditions or symptoms of a disease or injury to the nervous system. Such as: Acroanesthesia Loss of sensation in the extremities; such as the hands, fingers, toes, and feet. Acroparesthesia Disease marked by attacks of tingling in the outer parts of the body. Numbness, tingling, and/or other abnormal sensations of the extremities (for example, the fingers, hands, forearms, and toes); usually due to a carpal tunnel syndrome but also from other causes; seen frequently in organic disorders, especially peripheral nerve lesions.
Hypoesthesia Diminished sensitivity to tactile stimuli. Anesthesia 1. Total or partial loss of sensation, especially tactile sensibility, induced by disease, injury, acupuncture, or an anesthetic, such as chloroform or nitrous oxide. 2. A drug, administered for medical or surgical purposes, that induces partial or total loss of sensation and may be topical, local, regional, or general, depending on the method of administration and area of the body affected.
- plegia This suffix is also of Greek origin. It is derived from the Greek “plege” which means blow or stroke. -Plegia means stroke or incapacitation.
Paraplegia Paralysis of the legs. Hemiplegia Paralysis of one side of the body. Quadriplegia Paralysis of al 4 of the extremities. Myeloplegia Paralysis of the spinal cord. Neuroplegia Any paralysis due to an injury or disease of the nervous system.
