Prefixes – a word element at the beginning of the word to alter its meaning. A prefix can not stand alone; it must be combined with a root word A-, an-Without or not Intro-Into; within Ab-Away from Leuk-White Ad-Toward Macro-Large Ante-Before, forward Mal-Bad, illness, disease Anti-Against Mega-Large Auto-Self Micro-Small Bi-Double, two Mono-One, single Circum-Around Neo-New Contra-Against, opposite Non-Not Para-Abnormal Per-By, through Peri-Around Poly-Many, much Ecto-Outer, outside Post-After, behind En-In, into, within Endo-Inner, inside Pro-Before, in front Epi-Over, on Re-Again Eryth-Red Retro-Backward Ex-Out, out of Semi-Half Hemi-Half Sub-Under Hyper-Excessive Super- Above, over Hypo-Under, decreased Supra-Above, over In-In, into, within, not Trans-Across Inter-Between Uni-One Intra-Within

Root words – provide the fundamental meaning of a term. Combinations of rootwords, prefixes and suffixes form medical and scientific terms. A vowel, called a combining vowel, often is added when two root words are combined or a suffix is added to a root word; the combining vowel is usually an o or an i.

Terminology of Location and Position C. Positional Terms 1. Anatomic position – stance of the body when erect, arms hanging at the sides, palms facing forward 2. Erect position – the body in a standing position 3. Supine position – the body lying in a horizontal position with face up 4. Prone position – the body in horizontal position with face down 5. Laterally recumbent position – the body lying horizontally on either the right or left side

The EndLets review terms

Medical Terminology Tissue – a collection of similar cells acting together to form a particicular function Epithelial – closely packed single or stratified layer of cells (skin) covering the body and lining its cavities with the exception of blood and lymph vessels Connective – tissue that supports and binds other tissue and parts Muscular – tissues that are contractible – 3 types: cardiac, smooth muscle and skeletal Nervous – CNS – brain and spinal cord PNS – cranial and spinal nerves ANS – nerves in thoracic, lumbar, cranial and sacral segments of the Spinal cord

Medical Terminology Histo - tissue Histology – study of microscopic anatomic and physiologic characteristics of tissues and cells therein Organ – structural part of a system of the body that is composed of tissue and cells that enable it to perform a particular function Bone – a dense, hard and somewhat flexible connective tissue Os, ossa, oste, osteo – having to do with bone

Medical Terminology Tendon – any one of the white, glistening bands of dense, fibrous connective tissue that attaches muscle to bone Ligament – shiny white flexible bands of fibrous tissue binding joints together and connecting articular bones and cartilages to facilitate movement Cartilage – a nonvascular dense supporting connective tissue composed of ground substance Hyaline cartilage – a type of elastic connective tissue composed of Specialized cells in a translucent, pearly blue matrix covering articulating ends of bones Fibrocartilage – Cartilage that consists of a dense matrix of white collagenous fibers.

Medical Terminology Joint – any one of the articulations between bones Articulation – movements of joints Bursae – a fibrous sac between certain tendons and the bones beneath them. The bursae acts as a small cushion that allows the tendons to move over the bone as it contracts and releases Osteoblasts – a bone forming cell during early development of the skeleton, differentiates from a fibroblast to function in the formation of bone tissue Osteoclasts – a large type of multinucleated bone cell with a large amount of acidophilic cytoplasm that functions to absorb and remove osseos tissue

Medical Terminology Manubrium – most anterior of the 3 bones of the sternum Xiphoid Process – the smallest of 3 parts of the sternum Malleolus – a rounded bony process such as each side of the ankle Process – a natural growth that projects from a bone Crest – a narrow, elongated elevation

Osteoporosis – a disorder characterized by abnormal loss of bone density and deterioration of bone tissue, with an increased fracture risk. Spondylitis – an inflammation of any of the vertebrae, usually characterized by stiffness and pain.

Medical Terminology Atrophy – a wasting or decrease in size or physiologic activity of a part of the body because of disease or other influence. Benign – noncancerous and therefore not an immediate threat. Chronic – persisting for a long period, often for the remainder of a persons lifetime. Clinical – pertaining to a clinic, to direct bedside medical or nursing care, to materials or equipment used in the care of a sick person. Diagnosis – identification of a disease or condition by a scientific evaluation of physical signs, symptoms, history, laboratory test results, and procedures.

Metastatic – the process by which tumor cells spread to distant parts of the body. Prognosis – a prediction of the probable outcome of a disease based on the condition of the person and the usual course of the disease as observed in similar situations. Sign – an objective finding as perceived by an examiner, such as fever, rash.

Medical Terminology Symptom – a subjective indication of a disease or a change in condition as perceived by the patient. Syndrome – a complex of signs and symptoms resulting from a common cause or appearing, in combination, to present a clinical picture of a disease or inherited abnormality. Systemic – pertaining to the whole body rather than to a localized area or region of the body. Bacterial – of or pertaining to bacteria. Cancer – a neoplasm characterized by the uncontrolled growth of anaplastic cells that tend to invade surrounding tissue and to metastasize to distant body parts.

Medical Terminology Congenital – present at birth, as in anomaly or defect Degenerative – pertaining to or involving degeneration or change to a lower or dysfunctional form. Epidemic – affecting a significantly large number of people at the same time. Exacerbation – an increase in the seriousness of a disease or disorderas marked by greater intensity in the signs and symptoms of the patient being treated Idiopathic – without a know cause
